ENCYCLICAL LETTER

To All the Bishops of the Catholic Church

Regarding Certain Fundamental Questions of the Church's Moral Teaching

Venerable Brothers in the Episcopate, Health and the Apostolic Blessing!

THE SPLENDOR OF TRUTH shines forth in the works of the Creator and, in a special way, in man, created in the image and likeness of God (cf. Gen 1:26). Truth enlightens man's intelligence and shapes his freedom, leading him to know and love the Lord. Hence the Psalmist prays: "Let the light of your face shine on us, O Lord" (Ps 4:6).

Introduction

Jesus Christ, the True Light that Enlightens Everyone

1. Called to salvation through faith in Jesus Christ, "the true light that enlightens everyone" (Jn 1:9), people become "light in the Lord" and "children of light" (Eph 5:8), and are made holy by "obedience to the truth" (1 Pet 1:22).

This obedience is not always easy. As a result of that mysterious original sin, committed at the prompting of Satan, the one who is "a liar and the father of lies" (Jn 8:44), man is constantly tempted to turn his gaze away from the living and true God in order to direct it towards idols (cf. 1 Thes 1:9), exchanging "the truth about God for a lie" (Rom 1:25). Man's capacity to know the truth is also darkened, and his will to submit to it is weakened. Thus, giving himself over to relativism and skepticism (cf. Jn 18:38), he goes off in search of an illusory freedom apart from truth itself.

But no darkness of error or of sin can totally take away from man the light of God the Creator. In the depths of his heart there always remains a yearning for absolute truth and a thirst to attain full knowledge of it. This is eloquently proved by man's tireless search for knowledge in all fields. It is proved even more by his search for the meaning of life. The development of science and technology, this splendid testimony of the human capacity for understanding and for perseverance, does not free humanity from the obligation to ask the ultimate religious questions. Rather, it spurs us on to face the most painful and decisive of struggles, those of the heart and of the moral conscience.

2. No one can escape from the fundamental questions: What must I do? How do I distinguish good from evil? The answer is only possible thanks to the splendor of the truth which shines forth deep within the human spirit, as the Psalmist bears witness: "There are many who say: 'O that we might see some good! Let the light of your face shine on us, O Lord,"' (Ps 4:6).

The light of God's face shines in all its beauty on the countenance of Jesus Christ, "the image of the invisible God" (Col 1:15), the "reflection of God's glory" (Heb 1:3), "full of grace and truth" (Jn 1:14). Christ is "the way, and the truth, and the life" (Jn 14:6). Consequently the decisive answer to every one of man's questions, his religious and moral questions in particular, is given by Jesus Christ, or rather is Jesus Christ himself, as the Second Vatican Council recalls: "In fact, it is only in the mystery of the Word incarnate that light is shed on the mystery of man. For Adam, the first man, was a figure of the future man, namely, of Christ the Lord. It is Christ, the last Adam, who fully discloses man to himself and unfolds his noble calling by revealing the mystery of the Father and the Father's love."(1)

Jesus Christ, the "light of the nations," shines upon the face of his Church, which he sends forth to the whole world to proclaim the Gospel to every creature (cf. Mk 16:15).(2) Hence the Church, as the People of God among the nations,(3) while attentive to the new challenges of history and to mankind's efforts to discover the meaning of life, offers to everyone the answer which comes from the truth about Jesus Christ and his Gospel. The Church remains deeply conscious of her "duty in every age of examining the signs of the times and interpreting them in the light of the Gospel, so that she can offer in a manner appropriate to each generation replies to the continual human questionings on the meaning of this life and the life to come and on how they are related."(4)

3. The Church's Pastors, in communion with the Successor of Peter, are close to the faithful in this effort; they guide and accompany them by their authoritative teaching, finding ever new ways of speaking with love and mercy not only to believers but to all people of good will. The Second Vatican Council remains an extraordinary witness of this attitude on the part of the Church which, as an "expert in humanity,"(5) places herself at the service of every individual and of the whole world.(6) The Church knows that the issue of morality is one which deeply touches every person; it involves all people, even those who do not know Christ and his Gospel or God himself. She knows that it is precisely on the path of the moral life that the way of salvation is open to all. The Second Vatican Council clearly recalled this when it stated that "those who without any fault do not know anything about Christ or his Church, yet who search for God with a sincere heart and under the influence of grace, try to put into effect the will of God as known to them through the dictate of conscience...can obtain eternal salvation." The Council added: "Nor does divine Providence deny the helps that are necessary for salvation to those who, through no fault of their own have not yet attained to the express recognition of God, yet who strive, not without divine grace, to lead an upright life. For whatever goodness and truth is found in them is considered by the Church as a preparation for the Gospel and bestowed by him who enlightens everyone that they may in the end have life."(7)

The Purpose of the Present Encyclical

4. At all times, but particularly in the last two centuries, the Popes, whether individually or together with the College of Bishops, have developed and proposed a moral teaching regarding the many different spheres of human life. In Christ's name and with his authority they have exhorted, passed judgment and explained. In their efforts on behalf of humanity, in fidelity to their mission, they have confirmed, supported and consoled. With the guarantee of assistance from the Spirit of truth they have contributed to a better understanding of moral demands in the areas of human sexuality, the family, and social, economic and political life. In the tradition of the Church and in the history of humanity, their teaching represents a constant deepening of knowledge with regard to morality.(8)

Today, however, it seems necessary to reflect on the whole of the Church's moral teaching, with the precise goal of recalling certain fundamental truths of Catholic doctrine which, in the present circumstances, risk being distorted or denied. In fact, a new situation has come about within the Christian community itself, which has experienced the spread of numerous doubts and objections of a human and psychological, social and cultural, religious and even properly theological nature, with regard to the Church's moral teachings. It is no longer a matter of limited and occasional dissent, but of an overall and systematic calling into question of traditional moral doctrine, on the basis of certain anthropological and ethical presuppositions. At the root of these presuppositions is the more or less obvious influence of currents of thought which end by detaching human freedom from its essential and constitutive relationship to truth. Thus the traditional doctrine regarding the natural law, and the universality and the permanent validity of its precepts, is rejected; certain of the Church's moral teachings are found simply unacceptable; and the Magisterium itself is considered capable of intervening in matters of morality only in order to "exhort consciences" and to "propose values," in the light of which each individual will independently make his or her decisions and life choices.

In particular, note should be taken of the lack of harmony between the traditional response of the Church and certain theological positions, encountered even in seminaries and in faculties of theology, with regard to questions of the greatest importance for the Church and for the life of faith of Christians, as well as for the life of society itself. In particular, the question is asked: do the commandments of God, which are written on the human heart and are part of the Covenant, really have the capacity to clarify the daily decisions of individuals and entire societies? Is it possible to obey God and thus love God and neighbor, without respecting these commandments in all circumstances? Also, an opinion is frequently heard which questions the intrinsic and unbreakable bond between faith and morality, as if membership in the Church and her internal unity were to be decided on the basis of faith alone, while in the sphere of morality a pluralism of opinions and of kinds of behavior could be tolerated, these being left to the judgment of the individual subjective conscience or to the diversity of social and cultural contexts.

5. Given these circumstances, which still exist, I came to the decision—as I announced in my Apostolic Letter Spiritus Domini, issued on August 1, 1987 on the second centenary of the death of Saint Alphonsus Maria de Liguori—to write an encyclical with the aim of treating "more fully and more deeply the issues regarding the very foundations of moral theology,"(9) foundations which are being undermined by certain present-day tendencies.

I address myself to you, Venerable Brothers in the Episcopate, who share with me the responsibility of safeguarding "sound teaching" (2 Tim 4:3), with the intention of clearly setting forth certain aspects of doctrine which are of crucial importance in facing what is certainly a genuine crisis, since the difficulties which it engenders have most serious implications for the moral life of the faithful and for communion in the Church, as well as for a just and fraternal social life.

If this encyclical, so long awaited, is being published only now, one of the reasons is that it seemed fitting for it to be preceded by the Catechism of the Catholic Church, which contains a complete and systematic exposition of Christian moral teaching. The Catechism presents the moral life of believers in its fundamental elements and in its many aspects as the life of the "children of God": "Recognizing in the faith their new dignity, Christians are called to lead henceforth a life 'worthy of the Gospel of Christ' (Phil 1:27). Through the sacraments and prayer they receive the grace of Christ and the gifts of his Spirit which make them capable of such a life."(10) Consequently, while referring to the Catechism "as a sure and authentic reference text for teaching Catholic doctrine,"(11) the encyclical will limit itself to dealing with certain fundamental questions regarding the Church's moral teaching, taking the form of a necessary discernment about issues being debated by ethicists and moral theologians. The specific purpose of the present encyclical is this: to set forth, with regard to the problems being discussed, the principles of a moral teaching based upon Sacred Scripture and the living Apostolic Tradition,(12) and at the same time to shed light on the presuppositions and consequences of the dissent which that teaching has met.

Chapter I

"Teacher, What Good Must I Do...?" (Mt 19:16)

Christ and the Answer to the Question About Morality

"Someone came to him..." (Mt 19:16)

6. The dialogue of Jesus with the rich young man, related in the nineteenth chapter of Saint Matthew's Gospel, can serve as a useful guide for listening once more in a lively and direct way to his moral teaching: "Then someone came to him and said, 'Teacher, what good must I do to have eternal life?' And he said to him, 'Why do you ask me about what is good? There is only one who is good. If you wish to enter into life, keep the commandments.' He said to him, 'Which ones?' And Jesus said, 'You shall not murder; You shall not commit adultery; You shall not steal; You shall not bear false witness; Honor your father and mother; also, You shall love your neighbor as yourself.' The young man said to him, 'I have kept all these; what do I still lack?' Jesus said to him, 'If you wish to be perfect, go, sell your possessions and give the money to the poor, and you will have treasure in heaven; then come, follow me"' (Mt 19:16-21).(13)

7. "Then someone came to him...." In the young man, whom Matthew's Gospel does not name, we can recognize every person who, consciously or not, approaches Christ the Redeemer of man and questions him about morality. For the young man, the question is not so much about rules to be followed, but about the full meaning of life. This is in fact the aspiration at the heart of every human decision and action, the quiet searching and interior prompting which sets freedom in motion. This question is ultimately an appeal to the absolute Good which attracts us and beckons us; it is the echo of a call from God who is the origin and goal of man's life. Precisely in this perspective the Second Vatican Council called for a renewal of moral theology, so that its teaching would display the lofty vocation which the faithful have received in Christ, (14) the only response fully capable of satisfying the desire of the human heart.

In order to make this "encounter" with Christ possible, God willed his Church. Indeed, the Church "wishes to serve this single end: that each person may be able to find Christ, in order that Christ may walk with each person the path of life."(15)

"Teacher, what good must do to have eternal life?" (Mt 19:16)

8. The question which the rich young man puts to Jesus of Nazareth is one which rises from the depths of his heart. It is an essential and unavoidable question for the life of every man, for it is about the moral good which must be done, and about eternal life. The young man senses that there is a connection between moral good and the fulfillment of his own destiny. He is a devout Israelite, raised as it were in the shadow of the Law of the Lord. If he asks Jesus this question we can presume that it is not because he is ignorant of the answer contained in the Law. It is more likely that the attractiveness of the person of Jesus had prompted within him new questions about moral good. He feels the need to draw near to the One who had begun his preaching with this new and decisive proclamation: "The time is fulfilled and the Kingdom of God is at hand; repent, and believe in the Gospel" (Mk 1:15).

People today need to turn to Christ once again in order to receive from him the answer to their questions about what is good and what is evil. Christ is the Teacher, the Risen One who has life in himself and who is always present in his Church and in the world. It is he who opens up to the faithful the book of the Scriptures and, by fully revealing the Father's will, teaches the truth about moral action. At the source and summit of the economy of salvation, as the Alpha and the Omega of human history (cf. Rev 1-8; 21-6; 22-13), Christ sheds light on man's condition and his integral vocation. Consequently, "the man who wishes to understand himself thoroughly—and not just in accordance with immediate, partial, often superficial and even illusory standards and measures of his being—must, with his unrest, uncertainty and even his weakness and sinfulness, with his life and death, draw near to Christ. He must, so to speak, enter him with all his own self, he must 'appropriate' and assimilate the whole of the reality of the Incarnation and Redemption in order to find himself. If this profound process takes place within him, he then bears fruit not only of adoration of God but also of deeper wonder at himself."(16)

If we therefore wish to go to the heart of the Gospel's moral teaching and grasp its profound and unchanging content, we must carefully inquire into the meaning of the question asked by the rich young man in the Gospel and, even more, the meaning of Jesus' reply, allowing ourselves to be guided by him. Jesus, as a patient and sensitive teacher, answers the young man by taking him, as it were, by the hand, and leading him step by step to the full truth.

"There is only one who is good" (Mt 19:17)

9. Jesus says: "Why do you ask me about what is good? There is only one who is good. If you wish to enter into life, keep the commandments" (Mt 19:17). In the versions of the Evangelists Mark and Luke the question is phrased in this way: "Why do you call me good? No one is good but God alone" (Mk 10:18; cf. Lk 18:19).

Before answering the question, Jesus wishes the young man to have a clear idea of why he asked his question. The "Good Teacher" points out to him—and to all of us—that the answer to the question, "What good must I do to have eternal life?" can only be found by turning one's mind and heart to the "One" who is good: "No one is good but God alone" (Mk 10:18; cf. Lk 18:19). Only God can answer the question about what is good, because he is the Good itself.

To ask about the good, in fact, ultimately means to turn towards God, the fullness of goodness. Jesus shows that the young man's question is really a religious question, and that the goodness that attracts and at the same time obliges man has its source in God, and indeed is God himself. God alone is worthy of being loved "with all one's heart, and with all one's soul, and with all one's mind" (Mt 22:37). He is the source of man's happiness. Jesus brings the question about morally good action back to its religious foundations, to the acknowledgment of God, who alone is goodness, fullness of life, the final end of human activity, and perfect happiness.

10. The Church, instructed by the Teacher's words, believes that man, made in the image of the Creator, redeemed by the Blood of Christ and made holy by the presence of the Holy Spirit, has as the ultimate purpose of his life to live "for the praise of God's glory" (cf. Eph 1:12), striving to make each of his actions reflect the splendor of that glory. "Know, then, O beautiful soul, that you are the image of God," writes Saint Ambrose. "Know that you are the glory of God (1 Cor 11:7). Hear how you are his glory. The Prophet says: Your knowledge has become too wonderful for me (cf. Ps 138:6, Vulg.). That is to say, in my work your majesty has become more wonderful; in the counsels of men your wisdom is exalted. When I consider myself, such as I am known to you in my secret thoughts and deepest emotions, the mysteries of your knowledge are disclosed to me. Know then, O man, your greatness, and be vigilant." (17)

What man is and what he must do becomes clear as soon as God reveals himself. The Decalogue is based on these words: "I am the Lord your God, who brought you out of the land of Egypt, out of the house of bondage" (Ex 20:2-3). In the "ten words" of the Covenant with Israel, and in the whole Law, God makes himself known and acknowledged as the one who "alone is good"; the One who, despite man's sin, remains the "model" for moral action in accordance with his command, "You shall be holy; for I the Lord your God am holy" (Lev 19:2); as the One who, faithful to his love for man, gives him his Law (cf. Ex 19:9-24 and 20:18-21) in order to restore man's original and peaceful harmony with the Creator and with all creation, and, what is more, to draw him into his divine love: "I will walk among you, and will be your God, and you shall be my people" (Lev 26:12).

The moral life presents itself as the response due to the many gratuitous initiatives taken by God out of love for man. It is a response of love, according to the statement made in Deuteronomy about the fundamental commandment; "Hear, O Israel: The Lord our God is one Lord; and you shall love the Lord your God with all your heart, and with all your soul, and with all your might. And these words which I command you this day shall be upon your heart; and you shall teach them diligently to your children" (Dt 6:4-7). Thus the moral life, caught up in the gratuitousness of God's love, is called to reflect his glory: "For the one who loves God it is enough to be pleasing to the One whom he loves: for no greater reward should be sought than that love itself; charity in fact is of God in such a way that God himself is charity."(18)

11. The statement that "There is only one who is good" thus brings us back to the "first tablet" of the commandments, which calls us to acknowledge God as the one Lord of all and to worship him alone for his infinite holiness (cf. Ex 20:2-11). The good is belonging to God, obeying him, walking humbly with him in doing justice and in loving kindness (cf. Mic1:8). Acknowledging the Lord as God is the very core, the heart of the Law, from which the particular precepts flow and towards which they are ordered. In the morality of the commandments the fact that the people of Israel belong to the Lord is made evident, because God alone is the One who is good. Such is the witness of Sacred Scripture, imbued in every one of its pages with a lively perception of God's absolute holiness: "Holy, holy, holy is the Lord of hosts" (Is 6:3).

But if God alone is the Good, no human effort, not even the most rigorous observance of the commandments, succeeds in "fulfilling" the Law, that is, acknowledging the Lord as God and rendering him the worship due to him alone (cf. Mt 4:10). This "fulfillment" can come only from a gift of God: the offer of a share in the divine Goodness revealed and communicated in Jesus, the one whom the rich young man addresses with the words "Good Teacher" (Mk 10:17; Lk 18:18). What the young man now perhaps only dimly perceives will, in the end, be fully revealed by Jesus himself in the invitation: "Come, follow me" (Mt 19:21).

"If you wish to enter into life, keep the commandments" (Mt 19:17)

12. Only God can answer the question about the good, because he is the Good. But God has already given an answer to this question: he did so by creating man and ordering him with wisdom and love to his final end, through the law which is inscribed in his heart (cf. Rom 2:15), the "natural law." The latter "is nothing other than the light of understanding infused in us by God, whereby we understand what must be done and what must be avoided. God gave this light and this law to man at creation."(19) He also did so in the history of Israel, particularly in the "ten words," the commandments of Sinai, whereby he brought into existence the people of the Covenant (cf. Ex 24) and called them to be his "own possession among all peoples," "a holy nation" (Ex 19:5-6), which would radiate his holiness to all peoples (cf. Wis 18:4; Ez 20:41). The gift of the Decalogue was a promise and sign of the New Covenant, in which the law would be written in a new and definitive way upon the human heart (cf. Jer 31:31-34), replacing the law of sin which had disfigured that heart (cf. Jer 17:1). In those days, "a new heart" would be given, for in it would dwell "a new spirit," the Spirit of God (cf. Ez 36:24-28).(20)

Consequently, after making the important clarification: "There is only one who is good," Jesus tells the young man: "If you wish to enter into life, keep the commandments" (Mt 19:17). In this way, a close connection is made between eternal life and obedience to God's commandments: God's commandments show man the path of life and they lead to it. From the very lips of Jesus, the new Moses, man is once again given the commandments of the Decalogue. Jesus himself definitively confirms them and proposes them to us as the way and condition of salvation. The commandments are linked to a promise. In the Old Covenant the object of the promise was the possession of a land where the people would be able to live in freedom and in accordance with righteousness (cf. Dt 6:20-25). In the New Covenant the object of the promise is the "Kingdom of Heaven," as Jesus declares at the beginning of the "Sermon on the Mount"—a sermon which contains the fullest and most complete formulation of the New Law (cf. Mt 5-7), clearly linked to the Decalogue entrusted by God to Moses on Mount Sinai. This same reality of the Kingdom is referred to in the expression "eternal life," which is a participation in the very life of God. It is attained in its perfection only after death, but in faith it is even now a light of truth, a source of meaning for life, an inchoate share in the full following of Christ. Indeed, Jesus says to his disciples after speaking to the rich young man: "Every one who has left houses or brothers or sisters or father or mother or children or lands, for my name's sake, will receive a hundredfold and inherit eternal life" (Mt 19:29).

13. Jesus' answer is not enough for the young man, who continues by asking the Teacher about the commandments which must be kept: "He said to him, 'Which ones?"' (Mt 19:18). He asks what he must do in life in order to show that he acknowledges God's holiness. After directing the young man's gaze toward God, Jesus reminds him of the commandments of the Decalogue regarding one's neighbor: "Jesus said: 'You shall not murder; You shall not commit adultery; You shall not bear false witness; Honor your father and mother; also, You shall love your neighbor as yourself'" (Mt 19:18-19).

From the context of the conversation, and especially from a comparison of Matthew's text with the parallel passages in Mark and Luke, it is clear that Jesus does not intend to list each and every one of the commandments required in order to "enter into life," but rather wishes to draw the young man's attention to the "centrality" of the Decalogue with regard to every other precept, inasmuch as it is the interpretation of what the words "I am the Lord your God" mean for man. Nevertheless we cannot fail to notice which commandments of the Law the Lord recalls to the young man. They are some of the commandments belonging to the so–called "second tablet" of the Decalogue, the summary (cf. Rom 13:8-10) and foundation of which is the commandment of love of neighbor: "You shall love your neighbor as yourself" (Mt 19:19; cf. Mk 12:31). In this commandment we find a precise expression of the singular dignity of the human person, "the only creature that God has wanted for its own sake."(21) The different commandments of the Decalogue are really only so many reflections of the one commandment about the good of the person, at the level of the many different goods which characterize his identity as a spiritual and bodily being in relationship with God, with his neighbor and with the material world. As we read in the Catechism of the Catholic Church, "the Ten Commandments are part of God's Revelation. At the same time, they teach us man's true humanity. They shed light on the essential duties, and so indirectly on the fundamental rights, inherent in the nature of the human person."(22)

The commandments of which Jesus reminds the young man are meant to safeguard the good of the person, the image of God, by protecting his goods. "You shall not murder; You shall not commit adultery; You shall not steal; You shall not bear false witness" are moral rules formulated in terms of prohibitions. These negative precepts express with particular force the ever urgent need to protect human life, the communion of persons in marriage, private property, truthfulness and people's good name.

The commandments thus represent the basic condition for love of neighbor; at the same time they are the proof of that love. They are the first necessary step on the journey towards freedom, its starting-point. "The beginning of freedom," Saint Augustine writes, "is to be free from crimes...such as murder, adultery, fornication, theft, fraud, sacrilege and so forth. Once one is without these crimes (and every Christian should be without them), one begins to lift up one's head toward freedom. But this is only the beginning of freedom, not perfect freedom...."(23)

14. This certainly does not mean that Christ wishes to put the love of neighbor higher than, or even to set it apart from, the love of God. This is evident from his conversation with the teacher of the Law, who asked him a question very much like the one asked by the young man. Jesus refers him to the two commandments of love of God and love of neighbor (cf. Lk 10:25-27), and reminds him that only by observing them will he have eternal life: "Do this, and you will live" (Lk 10:28). Nonetheless it is significant that it is precisely the second of these commandments which arouses the curiosity of the teacher of the Law, who asks him: "And who is my neighbor?" Lk 10:29). The Teacher replies with the parable of the Good Samaritan, which is critical for fully understanding the commandment of love of neighbor (cf. Lk 10:30-37).

These two commandments, on which "depend all the Law and the Prophets" (Mt 22:40), are profoundly connected and mutually related. Their inseparable unity is attested to by Christ in his words and by his very life: his mission culminates in the Cross of our Redemption (cf. Jn 3:14-15), the sign of his indivisible love for the Father and for humanity (cf. Jn 13:1).

Both the Old and the New Testaments explicitly affirm that without love of neighbor, made concrete in keeping the commandments, genuine love for God is not possible. Saint John makes the point with extraordinary forcefulness: "If anyone says, 'I love God,' and hates his brother, he is a liar; for he who does not love his brother whom he has seen, cannot love God whom he has not seen" (1 Jn 4:20). The Evangelist echoes the moral preaching of Christ, expressed in a wonderful and unambiguous way in the parable of the Good Samaritan (cf. Lk 10:30-37) and in his words about the final judgment (cf. Mt 25:31-46).

15. In the "Sermon on the Mount," the magna charta of Gospel morality,(24) Jesus says: "Do not think that I have come to abolish the Law and the Prophets; I have come not to abolish them but to fulfill them" (Mt 5:17). Christ is the key to the Scriptures: "You search the Scriptures...; and it is they that bear witness to me" (Jn 5:39). Christ is the center of the economy of salvation, the recapitulation of the Old and New Testaments, of the promises of the Law and of their fulfillment in the Gospel; he is the living and eternal link between the Old and the New Covenants. Commenting on Paul's statement that "Christ is the end of the law" (Rom 10:4), Saint Ambrose writes: "end not in the sense of a deficiency, but in the sense of the fullness of the Law: a fullness which is achieved in Christ (plenitudo legis in Christo est), since he came not to abolish the Law but to bring it to fulfillment. In the same way that there is an Old Testament, but all truth is in the New Testament, so it is for the Law: what was given through Moses is a figure of the True law. Therefore, the Mosaic Law is an image of the truth."(25)

Jesus brings God's commandments to fulfillment, particularly the commandment of love of neighbor, by interiorizing their demands and by bringing out their fullest meaning. Love of neighbor springs from a loving heart which, precisely because it loves, is ready to live out the loftiest challenges. Jesus shows that the commandments must not be understood as a minimum limit not to be gone beyond, but rather as a path involving a moral and spiritual journey towards perfection, at the heart of which is love (cf. Col 3:14). Thus the commandment "You shall not murder" becomes a call to an attentive love which protects and promotes the life of one's neighbor. The precept prohibiting adultery becomes an invitation to a pure way of looking at others, capable of respecting the spousal meaning of the body: "You have heard that it was said to the men of old, 'You shall not kill; and whoever kills shall be liable to judgment.' But I say to you that every one who is angry with his brother shall be liable to judgment.... You have heard that it was said, 'You shall not commit adultery.' But I say to you that every one who looks at a woman lustfully has already committed adultery with her in his heart" (Mt 5:21-22, 27-28). Jesus himself is the living "fulfillment" of the Law inasmuch as he fulfills its authentic meaning by the total gift of himself: he himself becomes a living and personal Law, who invites people to follow him; through the Spirit, he gives the grace to share his own life and love and provides the love and provides the strength to bear witness to that love in personal choices and actions (cf. Jn 13:34-35).

"If you wish to be perfect" (Mt 19:21)

16. The answer he receives about the commandments does not satisfy the young man, who asks Jesus a further question. "I have kept all these; what do I still lack?" (Mt 19:20). It is not easy to say with a clear conscience "I have kept all these," if one has any understanding of the real meaning of the demands contained in God's Law. And yet, even though he is able to make this reply, even though he has followed the moral ideal seriously and generously from childhood, the rich young man knows that he is still far from the goal: before the person of Jesus he realizes that he is still lacking something. It is his awareness of this insufficiency that Jesus addresses in his final answer. Conscious of the young man's yearning for something greater, which would transcend a legalistic interpretation of the commandments, the Good Teacher invites him to enter upon the path of perfection: "If you wish to be perfect, go, sell your possessions and give the money to the poor, and you will have treasure in heaven; then come, follow me" (Mt 19:21).

Like the earlier part of Jesus' answer, this part too must be read and interpreted in the context of the whole moral message of the Gospel, and in particular in the context of the Sermon on the Mount, the Beatitudes (cf. Mt 5:3-12), the first of which is precisely the Beatitude of the poor, the "poor in spirit" as Saint Matthew makes clear (Mt 5:3), the humble. In this sense it can be said that the Beatitudes are also relevant to the answer given by Jesus to the young man's question: "What good must I do to have eternal life?" Indeed, each of the Beatitudes promises, from a particular viewpoint, that very "good" which opens man up to eternal life, and indeed is eternal life.

The Beatitudes are not specifically concerned with certain particular rules of behavior. Rather, they speak of basic attitudes and dispositions in life and therefore they do not coincide exactly with the commandments. On the other hand, there is no separation or opposition between the Beatitudes and the commandments: both refer to the good, to eternal life. The Sermon on the Mount begins with the proclamation of the Beatitudes, but also refers to the commandments (cf. Mt 5:20-48). At the same time, the Sermon on the Mount demonstrates the openness of the commandments and their orientation toward the horizon of the perfection proper to the Beatitudes. These latter are above all promises, from which there also indirectly flow normative indications for the moral life. In their originality and profundity they are a sort of self-portrait of Christ, and for this very reason are invitations to discipleship and communion of life with Christ.(26)

17. We do not know how clearly the young man in the Gospel understood the profound and challenging import of Jesus' first reply: "If you wish to enter into life, keep the commandments." But it is certain that the young man's commitment to respect all the moral demands of the commandments represents the absolutely essential ground in which the desire for perfection can take root and mature, the desire, that is, for the meaning of the commandments to be completely fulfilled in following Christ. Jesus' conversation with the young man helps us to grasp the conditions for the moral growth of man, who has been called to perfection: the young man, having observed all the commandments, shows that he is incapable of taking the next step by himself alone. To do so requires mature human freedom ("If you wish to be perfect") and God's gift of grace ("Come, follow me").

Perfection demands that maturity in self-giving to which human freedom is called. Jesus points out to the young man that the commandments are the first and indispensable condition for having eternal life; on the other hand, for the young man to give up all he possesses and to follow the Lord is presented as an invitation: "If you wish...." These words of Jesus reveal the particular dynamic of freedom's growth towards maturity, and at the same time they bear witness to the fundamental relationship between freedom and divine Law. Human freedom and God's law are not in opposition; on the contrary, they appeal one to the other. The follower of Christ knows that his vocation is to freedom. "You were called to freedom, brethren" (Gal 5:13), proclaims the Apostle Paul with joy and pride. But he immediately adds; "only do not use your freedom as an opportunity for the flesh, but through love be servants of one another" (ibid.). The firmness with which the Apostle opposes those who believe that they are justified by the Law has nothing to do with man's "liberation" from precepts. On the contrary, the latter are at the service of the practice of love: "For he who loves his neighbor has fulfilled the Law. The commandments, 'You shall not commit adultery; You shall not murder; You shall not steal; You shall not covet,' and any other commandment, are summed up in this sentence, 'You shall love your neighbor as yourself"' (Rom 13:8-9). Saint Augustine, after speaking of the observance of the commandments as being a kind of incipient, imperfect freedom, goes on to say: "Why, someone will ask, is it not yet perfect? Because 'I see in my members another law at war with the law of my reason....' In part freedom, in part slavery: not yet complete freedom, not yet pure, not yet whole, because we are not yet in eternity. In part we retain our weakness and in part we have attained freedom. All our sins were destroyed in Baptism, but does it follow that no weakness remained after iniquity was destroyed? Had none remained, we would live without sin in this life. But who would dare to say this except someone who is proud, someone unworthy of the mercy of our deliverer...? Therefore, since some weakness has remained in us, I dare to say that to the extent to which we serve God we are free, while to the extent that we follow the law of sin, we are still slaves."(27)

18. Those who live "by the flesh" experience God's Law as a burden, and indeed as a denial or at least a restriction of their own freedom. On the other hand, those who are impelled by love and "walk by the Spirit" (Gal 5:16), and who desire to serve others, find in God's Law the fundamental and necessary way in which to practice love as something freely chosen and freely lived out. Indeed, they feel an interior urge—a genuine "necessity" and no longer a form of coercion—not to stop at the minimum demands of the Law, but to live them in their "fullness." This is a still uncertain and fragile journey as long as we are on earth, but it is one made possible by grace, which enables us to possess the full freedom of the children of God (cf. Rom 8:21) and thus to live our moral life in a way worthy of our sublime vocation as "sons in the Son."

This vocation to perfect love is not restricted to a small group of individuals. The invitation, "go, sell your possessions and give the money to the poor," and the promise "you will have treasure in heaven," are meant for everyone, because they bring out the full meaning of the commandment of love for neighbor, just as the invitation which follows, "Come, follow me," is the new, specific form of the commandment of love of God. Both the commandments and Jesus' invitation to the rich young man stand at the service of a single and indivisible charity, which spontaneously tends towards that perfection whose measure is God alone: "You, therefore, must be perfect, as your heavenly Father is perfect" (Mt 5:48). In the Gospel of Luke, Jesus makes even clearer the meaning of this perfection: "Be merciful, even as your Father is merciful" (Lk 6:36).

"Come, follow me" (Mt 19:21)

19. The way and at the same time the content of this perfection consists in the following of Jesus, sequela Christi, once one has given up one's own wealth and very self. This is precisely the conclusion of Jesus' conversation with the young man: "Come, follow me" (Mt 19:21). It is an invitation the marvelous grandeur of which will be fully perceived by the disciples after Christ's Resurrection, when the Holy Spirit leads them to all truth (cf. Jn 16:13).

It is Jesus himself who takes the initiative and calls people to follow him. His call is addressed first to those to whom he entrusts a particular mission, beginning with the Twelve; but it is also clear that every believer is called to be a follower of Christ (cf. Acts 6:1). Following Christ is thus the essential and primordial foundation of Christian morality: just as the people of Israel followed God who led them through the desert to wards the Promised Land (cf. Ex 13:21), so every disciple must follow Jesus, towards whom he is drawn by the Father himself (cf. Jn 6:44).

This is not a matter only of disposing oneself to hear a teaching and obediently accepting a commandment. More radically, it involves holding fast to the very person of Jesus, partaking of his life and his destiny, sharing in his free and loving obedience to the will of the Father. By responding in faith and following the one who is Incarnate Wisdom, the disciple of Jesus truly becomes a disciple of God (cf. Jn 6:45). Jesus is indeed the light of the world, the light of life (cf. Jn 8:12). He is the shepherd who leads his sheep and feeds them (cf. Jn 10:11-16); he is the way, and the truth, and the life (cf. Jn 14:6). It is Jesus who leads to the Father, so much so that to see him, the Son, is to see the Father (cf. Jn 14:6-10). And thus to imitate the Son, "the image of the invisible God" (Col 1:15), means to imitate the Father.

20. Jesus asks us to follow him and to imitate him along the path of love, a love which gives itself completely to the brethren out of love for God: "This is my commandment, that you love one another as I have loved you" (Jn 15:12). The word "as" requires imitation of Jesus and of his love, of which the washing of feet is a sign: "If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another's feet. For I have given you an example, that you should do as I have done to you" (Jn 13:14-15). Jesus' way of acting and his words, his deeds and his precepts constitute the moral rule of Christian life. Indeed, his actions, and in particular his Passion and Death on the Cross, are the living revelation of his love for the Father and for others. This is exactly the love that Jesus wishes to be imitated by all who follow him. It is the "new" commandment: "A new commandment I give to you, that you love one another; even as I have loved you, that you also love one another. By this all men will know that you are my disciples, if you have love for one another" (Jn 13:34-35).

The word "as" also indicates the degree of Jesus' love, and of the love with which his disciples are called to love one another. After saying: "This is my commandment, that you love one another as I have loved you" (Jn 15:12), Jesus continues with words which indicate the sacrificial gift of his life on the Cross, as the witness to a love "to the end" (Jn 13:1): "Greater love has no man than this, that a man lay down his life for his friends" (Jn 15:13).

As he calls the young man to follow him along the way of perfection, Jesus asks him to be perfect in the command of love, in "his" commandment: to become part of the unfolding of his complete giving, to imitate and rekindle the very love of the "Good" Teacher, the one who loved "to the end." This is what Jesus asks of everyone who wishes to follow him: "If any man would come after me, let him deny himself and take up his cross and follow me" (Mt 16:24).

21. Following Christ is not an outward imitation, since it touches man at the very depths of his being. Being a follower of Christ means becoming conformed to him who became a servant even to giving himself on the Cross (cf. Phil 2:5-8). Christ dwells by faith in the heart of the believer (cf. Eph 3:17), and thus the disciple is conformed to the Lord. This is the effect of grace, of the active presence of the Holy Spirit in us.

Having become one with Christ, the Christian becomes a member of his Body, which is the Church (cf. 1 Cor 12:13, 27). By the work of the Spirit, Baptism radically configures the faithful to Christ in the Paschal Mystery of death and resurrection; it "clothes him" in Christ (cf. Gal 3:27): "Let us rejoice and give thanks," exclaims Saint Augustine speaking to the baptized, "for we have become not only Christians, but Christ (...). Marvel and rejoice: we have become Christ!"(28) Having died to sin, those who are baptized receive new life (cf. Rom 6:3-11): alive for God in Christ Jesus, they are called to walk by the Spirit and to manifest the Spirit's fruits in their lives (cf. Gal 5:16-25). Sharing in the Eucharist, the sacrament of the New Covenant (cf. 1 Cor 11:23-29), is the culmination of our assimilation to Christ, the source of "eternal life" (cf. Jn 6:51-58), the source and power of that complete gift of self, which Jesus—according to the testimony handed on by Paul—commands us to commemorate in liturgy and in life: "As often as you eat this bread and drink the cup, you proclaim the Lord's death until he comes" (1 Cor 11:26).

"With God all things are possible" (Mt 19:26)

22. The conclusion of Jesus' conversation with the rich young man is very poignant: "When the young man heard this, he went away sorrowful, for he had many possessions" (Mt 19:22). Not only the rich man but the disciples themselves are taken aback by Jesus' call to discipleship, the demands of which transcend human aspirations and abilities: "When the disciples heard this, they were greatly astounded and said, 'Then who can be saved?"' (Mt 1-9:25). But the Master refers them to God's power: "With men this is impossible, but with God all things are possible" (Mt 19:26).

In the same chapter of Matthew's Gospel (19:3-10), Jesus, interpreting the Mosaic Law on marriage, rejects the right to divorce, appealing to a "beginning" more fundamental and more authoritative than the Law of Moses: God's original plan for mankind, a plan which man after sin has no longer been able to live up to: "For your hardness of heart Moses allowed you to divorce your wives, but from the beginning it was not so" (Mt 19:8). Jesus' appeal to the "beginning" dismays the disciples, who remark: "If such is the case of a man with his wife, it is not expedient to marry" (Mt 19:10). And Jesus, referring specifically to the charism of celibacy "for the Kingdom of Heaven" (Mt 19:12), but stating a general rule, indicates the new and surprising possibility opened up to man by God's grace. "He said to them: 'Not everyone can accept this saying, but only those to whom it is given"' (Mt 19:11).

To imitate and live out the love of Christ is not possible for man by his own strength alone. He becomes capable of this love only by virtue of a gift received. As the Lord Jesus receives the love of his Father, so he in turn freely communicates that love to his disciples: "As the Father has loved me, so have I loved you; abide in my love" (Jn 15:9). Christ's gift is his Spirit, whose first "fruit" (cf. Gal 5:22) is charity: "God's love has been poured into our hearts through the Holy Spirit which has been given to us" (Rom 5:5). Saint Augustine asks: "Does love bring about the keeping of the commandments, or does the keeping of the commandments bring about love?" And he answers: "But who can doubt that love comes first? For the one who does not love has no reason for keeping the commandments."(29)

23. "The law of the Spirit of life in Christ Jesus has set me free from the law of sin and death" (Rom 8:2). With these words the Apostle Paul invites us to consider in the perspective of the history of salvation, which reaches its fulfillment in Christ, the relationship between the (Old) Law and grace (the New Law). He recognizes the pedagogical function of the Law, which, by enabling sinful man to take stock of his own powerlessness and by stripping him of the presumption of his self-sufficiency, leads him to ask for and to receive "life in the Spirit." Only in this new life is it possible to carry out God's commandments. Indeed, it is through faith in Christ that we have been made righteous (cf. Rom 3:28): the "righteousness" which the Law demands, but is unable to give, is found by every believer to be revealed and granted by the Lord Jesus. Once again it is Saint Augustine who admirably sums up this Pauline dialectic of law and grace: "The law was given that grace might be sought; and grace was given, that the law might be fulfilled."(30)

Love and life according to the Gospel cannot be thought of first and foremost as a kind of precept, because what they demand is beyond man's abilities. They are possible only as a result of a gift of God who heals, restores and transforms the human heart by his grace: "For the law was given through Moses; grace and truth came through Jesus Christ" (Jn 1:17). The promise of eternal life is thus linked to the gift of grace, and the gift of the Spirit which we have received is even now the "guarantee of our inheritance" (Eph 1:14).

24. And so we find revealed the authentic and original aspect of the commandment of love and of the perfection to which it is ordered: we are speaking of a possibility opened up to man exclusively by grace, by the gift of God, by his love. On the other hand, precisely the awareness of having received the gift, of possessing in Jesus Christ the love of God, generates and sustains the free response of a full love for God and the brethren, as the Apostle John insistently reminds us in his first Letter: "Beloved, let us love one another; for love is of God and knows God. He who does not love does not know God; for God is love.... Beloved, if God so loved us, we ought also to love one another.... We love, because he first loved us" (1 Jn 4:7-8, 11, 19).

This inseparable connection between the Lord's grace and human freedom, between gift and task, has been expressed in simple yet profound words by Saint Augustine in his prayer: "Da quod iubes et iube quod vis" (grant what you command and command what you will).(31)

The gift does not lessen but reinforces the moral demands of love: "This is his commandment, that we should believe in the name of his Son Jesus Christ and love one another just as he has commanded us" (1 Jn 3:32). One can "abide" in love only by keeping the commandments, as Jesus states: "If you keep my commandments, you will abide in my love, just as I have kept my Father's commandments and abide in his love" (Jn 15:10).

Going to the heart of the moral message of Jesus and the preaching of the Apostles, and summing up in a remarkable way the great tradition of the Fathers of the East and West, and of Saint Augustine in particular, (32) Saint Thomas was able to write that the New Law is the grace of the Holy Spirit given through faith in Christ.(33) The external precepts also mentioned in the Gospel dispose one for this grace or produce its effects in one's life. Indeed, the New Law is not content to say what must be done, but also gives the power to "do what is true" (cf. Jn 3:21). Saint John Chrysostom likewise observed that the New Law was promulgated at the descent of the Holy Spirit from heaven on the day of Pentecost, and that the Apostles "did not come down from the mountain carrying, like Moses, tablets of stone in their hands; but they came down carrying the Holy Spirit in their hearts...having become by his grace a living law, a living book."(34)

"Lo, I am with you always, to the close of the age "(Mt 28:20)

25. Jesus' conversation with the rich young man continues, in a sense, in every period of history, including our own. The question: "Teacher, what good must I do to have eternal life?" arises in the heart of every individual, and it is Christ alone who is capable of giving the full and definitive answer. The Teacher who expounds God's commandments, who invites others to follow him and gives the grace for a new life, is always present and at work in our midst, as he himself promised: "Lo, I am with you always, to the close of the age" (Mt 28:20). Christ's relevance for people of all times is shown forth in his Body, which is the Church. For this reason the Lord promised his disciples the Holy Spirit, who would "bring to their remembrance" and teach them to understand his commandments (cf. Jn 14:26), and who would be the principle and constant source of a new life in the world (cf. Jn 3:5-8; Rom 8:1-13).

The moral prescriptions which God imparted in the Old Covenant, and which attained their perfection in the New and Eternal Covenant in the very person of the Son of God made man, must be faithfully kept and continually put into practice in the various different cultures throughout the course of history. The task of interpreting these prescriptions was entrusted by Jesus to the Apostles and their successors, with the special assistance of the Spirit of truth: "He who hears you hears me" (Lk 10:16). By the light and the strength of this Spirit the Apostles carried out their mission of preaching the Gospel and of pointing out the "way" of the Lord (cf. Acts 18:25), teaching above all how to follow and imitate Christ: "For to me to live is Christ" (Phil 1:21).

26. In the moral catechesis of the Apostles, besides exhortations and directions connected to specific historical and cultural situations, we find an ethical teaching with precise rules of behavior. This is seen in their Letters, which contain the interpretation, made under the guidance of the Holy Spirit, of the Lord's precepts as they are to be lived in different cultural circumstances (cf. Rom 12-15; 1 Cor 11-14; Gal 5-6; Eph 4-6; Col 3-4; 1 Pt and Jas). From the Church's beginnings, the Apostles, by virtue of their pastoral responsibility to preach the Gospel, were vigilant over the right conduct of Christians,(35) just as they were vigilant for the purity of the faith and the handing down of the divine gifts in the sacraments.(36) The first Christians, coming both from the Jewish people and from the Gentiles, differed from the pagans not only in their faith and their liturgy but also in the witness of their moral conduct, which was inspired by the New Law.(37) The Church is in fact a communion both of faith and of life; her rule of life is "faith working through love" (Gal 5:6).

No damage must be done to the harmony between faith and life: the unity of the Church is damaged not only by Christians who reject or distort the truths of faith but also by those who disregard the moral obligations to which they are called by the Gospel (cf. 1 Cor 5:9-13). The Apostles decisively rejected any separation between the commitment of the heart and the actions which express or prove it (cf. 1 Jn 2:3-6). And ever since Apostolic times the Church's Pastors have unambiguously condemned the behavior of those who fostered division by their teaching or by their actions.(38)

27. Within the unity of the Church, promoting and preserving the faith and the moral life is the task entrusted by Jesus to the Apostles (cf. Mt 28:19-20), a task which continues in the ministry of their successors. This is apparent from the living Tradition, whereby–as the Second Vatican Council teaches–"the Church, in her teaching, life and worship, perpetuates and hands on to every generation all that she is and all that she believes. This Tradition which comes from the Apostles, progresses in the Church under the assistance of the Holy Spirit."(39) In the Holy Spirit, the Church receives and hands down the Scripture as the witness to the "great things" which God has done in history (cf. Lk 1:49); she professes by the lips of her Fathers and Doctors the truth of the Word made flesh, puts his precepts and love into practice in the lives of her Saints and in the sacrifice of her Martyrs, and celebrates her hope in him in the Liturgy. By this same Tradition Christians receive "the living voice of the Gospel,"(40) as the faithful expression of God's wisdom and will.

Within Tradition, the authentic interpretation of the Lord's law develops, with the help of the Holy Spirit. The same Spirit who is at the origin of the Revelation of Jesus' commandments and teachings, guarantees that they will be reverently preserved, faithfully expounded and correctly applied in different times and places. This constant "putting into practice" of the commandments is the sign and fruit of a deeper insight into Revelation and of an understanding in the light of faith of new historical and cultural situations. Nevertheless, it can only confirm the permanent validity of revelation and follow in the line of the interpretation given to it by the great Tradition of the Church's teaching and life, as witnessed by the teaching of the Fathers, the lives of the Saints, the Church's Liturgy and the teaching of the Magisterium.

In particular, as the Council affirms, "the task of authentically interpreting the word of God, whether in its written form or in that of Tradition, has been entrusted only to those charged with the Church's living Magisterium, whose authority is exercised in the name of Jesus Christ. "(41) The Church, in her life and teaching, is thus revealed as "the pillar and bulwark of the truth" (1 Tm 3:15), including the truth regarding moral action. Indeed, "the Church has the right always and everywhere to proclaim moral principles, even in respect of the social order, and to make judgments about any human matter insofar as this is required by fundamental human rights or the salvation of souls."(42)

Precisely on the questions frequently debated in moral theology today and with regard to which new tendencies and theories have developed, the Magisterium, in fidelity to Jesus Christ and in continuity with the Church's tradition, senses more urgently the duty to offer its own discernment and teaching, in order to help man in his journey towards truth and freedom.

Chapter II

"Do Not Be Conformed to This World" (Rom 12:2)

The Church and the Discernment of Certain Tendencies in Present-Day Moral Theology

Teaching what befits sound doctrine (cf. Tit 2:1)

28. Our meditation on the dialog between Jesus and the rich young man has enabled us to bring together the essential elements of revelation in the Old and New Testament with regard to moral action. These are: the subordination of man and his activity to God, the One who "alone is good"; the relationship between the moral good of human acts and eternal life; Christian discipleship, which opens up before man the perspective of perfect love; and finally the gift of the Holy Spirit, source and means of the moral life of the "new creation" (cf. 2 Cor 5:17).

In her reflection on morality, the Church has always kept in mind the words of Jesus to the rich young man. Indeed, Sacred Scripture remains the living and fruitful source of the Church's moral doctrine; as the Second Vatican Council recalled, the Gospel is "the source of all saving truth and moral teaching."(43) The Church has faithfully preserved what the word of God teaches not only about truths which must be believed but also about moral action, action pleasing to God (cf. 1 Thes 4:1); she has achieved a doctrinal development analogous to that which has taken place in the realm of the truths of faith. Assisted by the Holy Spirit who leads her into all the truth (cf. Jn 16:13), the Church has not ceased, nor can she ever cease, to contemplate the "mystery of the Word Incarnate," in whom "light is shed on the mystery of man."(44)

29. The Church's moral reflection, always conducted in the light of Christ, the "Good Teacher," has also developed in the specific form of the theological science called "moral theology," a science which accepts and examines Divine Revelation while at the same time responding to the demands of human reason. Moral theology is a reflection concerned with "morality," with the good and the evil of human acts and of the person who performs them; in this sense it is accessible to all people. But it is also "theology," inasmuch as it acknowledges that the origin and end of moral action are found in the One who "alone is good" and who, by giving himself to man in Christ, offers him the happiness of divine life.

The Second Vatican Council invited scholars to take "special care for the renewal of moral theology" in such a way that "its scientific presentation, increasingly based on the teaching of Scripture, will cast light on the exalted vocation of the faithful in Christ and on their obligation to bear fruit in charity for the life of the world."(45) The Council also encouraged theologians, "while respecting the methods and requirements of theological science, to look for a more appropriate way of communicating doctrine to the people of their time; since there is a difference between the deposit or the truths of faith and the manner in which they are expressed, keeping the same meaning and the same judgment."(46) This led to a further invitation, one extended to all the faithful, but addressed to theologians in particular: "The faithful should live in the closest contact with others of their time, and should work for a perfect understanding of their modes of thought and feelings as expressed in their culture.(47)

The work of many theologians who found support in the Council's encouragement has already borne fruit in interesting and helpful reflections about the truths of faith to be believed and applied in life, reflections offered in a form better suited to the sensitivities and questions of our contemporaries. The Church, and particularly the Bishops, to whom Jesus Christ primarily entrusted the ministry of teaching, are deeply appreciative of this work, and encourage theologians to continue their efforts, inspired by that profound and authentic "fear of the Lord, which is the beginning of wisdom"(cf. Prov 1:7).

At the same time, however, within the context of the theological debates which followed the Council, there have developed certain interpretations of Christian morality which are not consistent with "sound teaching" (2 Tm 4:3). Certainly the Church's Magisterium does not intend to impose upon the faithful any particular theological system, still less a philosophical one. Nevertheless, in order to "reverently preserve and faithfully expound" the word of God,(48) the Magisterium has the duty to state that some trends of theological thinking and certain philosophical affirmations are incompatible with revealed truth.(49)

30. In addressing this encyclical to you, my Brother Bishops, it is my intention to state the principles necessary for discerning what is contrary to "sound doctrine," drawing attention to those elements of the Church's moral teaching which today appear particularly exposed to error, ambiguity or neglect. Yet these are the very elements on which there depends "the answer to the obscure riddles of the human condition which today also, as in the past, profoundly disturb the human heart. What is man? What is the meaning and purpose of our life? What is good and what is sin? What origin and purpose do sufferings have? What is the way to attain true happiness? What are death, judgment and retribution after death? Lastly, what is that final, unutterable mystery which embraces our lives and from which we take our origin and towards which we tend?"(50) These and other questions, such as: what is freedom and what is its relationship to the truth contained in God's Law? what is the role of conscience in man's moral development? how do we determine, in accordance with the truth about the good, the specific rights and duties of the human person?—can all be summed up in the fundamental question which the young man in the Gospel put to Jesus: "Teacher, what good must I do to have eternal life?" Because the Church has been sent by Jesus to preach the Gospel and to "make disciples of all nations..., teaching them to observe all" that he has commanded (cf. Mt 28:19-20), she today once more puts forward the Master's reply, a reply that possesses a light and a power capable of answering even the most controversial and complex questions. This light and power also impel the Church constantly to carry out not only her dogmatic but also her moral reflection within an interdisciplinary context, which is especially necessary in facing new issues.(51)

It is in the same light and power that the Church's Magisterium continues to carry out its task of discernment, accepting and living out the admonition addressed by the Apostle Paul to Timothy: "I charge you in the presence of God and of Christ Jesus who is to judge the living and the dead, and by his appearing and his kingdom: preach the word, be urgent in season and out of season, convince, rebuke, and exhort, be unfailing in patience and in teaching. For the time will come when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own likings, and will turn away from listening to the truth and wander into myths. As for you, always be steady, endure suffering, do the work of an evangelist, fulfill your ministry" (2 Tm 4:1-5; cf. Tit 1:10,13-14).

"You will know the truth, and the truth will make you free" (Jn 8:32)

31. The human issues most frequently debated and differently resolved in contemporary moral reflection are all closely related, albeit in various ways, to a crucial issue: human freedom.

Certainly people today have a particularly strong sense of freedom. As the Council's Declaration on Religious Freedom Dignitatis Humanae had already observed, "the dignity of the human person is a concern of which people of our time are becoming increasingly more aware."(52)

Hence the insistent demand that people be permitted to "enjoy the use of their own responsible judgment and freedom, and decide on their actions on grounds of duty and conscience, without external pressure or coercion."(53) In particular, the right to religious freedom and to respect for conscience on its journey towards the truth is increasingly perceived as the foundation of the cumulative rights of the person.(54)

This heightened sense of the dignity of the human person and of his or her uniqueness, and of the respect due to the journey of conscience, certainly represents one of the positive achievements of modern culture. This perception, authentic as it is, has been expressed in a number of more or less adequate ways, some of which however diverge from the truth about man as a creature and the image of God, and thus need to be corrected and purified in the light of faith.(55)

32. Certain currents of modern thought have gone so far as to exalt freedom to such an extent that it becomes an absolute, which would then be the resource of values. This is the direction taken by doctrines which have lost the sense of the transcendent or which are explicitly atheistic. The individual conscience is accorded the status of a supreme tribunal of moral judgment which hands down categorical and infallible decisions about good and evil. To the affirmation that one has a duty to follow one's conscience is unduly added the affirmation that one's moral judgment is true merely by the fact that it has its origin in conscience. But in this way the inescapable claims of truth disappear, yielding their place to a criterion of sincerity, authenticity and "being at peace with oneself," so much so that some have come to adopt a radically subjectivistic conception of moral judgment.

As is immediately evident, the crisis of truth is not unconnected with this development. Once the idea of a universal truth about the good, knowable by human reason, is lost, inevitably the notion of conscience also changes. Conscience is no longer considered in its primordial reality as an act of a person's intelligence, the function of which is to apply the universal knowledge of the good in a specific situation and thus to express a judgment about the right conduct to be chosen here and now. Instead, there is a tendency to grant to the individual conscience the prerogative of independently determining the criteria of good and evil and then acting accordingly. Such an outlook is quite congenial to an individualistic ethic, wherein each individual is faced with his own truth, different from the truth of others. Taken to its extreme consequences, this individualism leads to a denial of the very idea of human nature.

These different notions are at the origin of currents of thought which posit a radical opposition between moral law and conscience, and between nature and freedom.

33. Side by side with its exaltation of freedom, yet oddly in contrast with it, modern culture radically questions the very existence of this freedom. A number of disciplines, grouped under the name of the "behavioral sciences," have rightly drawn attention to the many kinds of psychological and social conditioning which influence the exercise of human freedom. Knowledge of these conditionings and the study they have received represent important achievements which have found application in various areas, for example in pedagogy or the administration of justice. But some people, going beyond the conclusions which can be legitimately drawn from these observations, have come to question or even deny the very reality of human freedom.

Mention should also be made here of theories which misuse scientific research about the human person. Arguing from the great variety of customs, behavior patterns and institutions present in humanity, these theories end up, if not with an outright denial of universal human values, at least with a relativistic conception of morality.

34. "Teacher, what good must I do to have eternal life?" The question of morality, to which Christ provides the answer, cannot prescind from the issue of freedom. Indeed, it considers that issue central, for there can be no morality without freedom: "It is only in freedom that man can turn to what is good."(56) But what sort of freedom? The Council, considering our contemporaries who "highly regard" freedom and "assiduously pursue" it, but who "often cultivate it in wrong ways as a license to do anything they please, even evil," speaks of "genuine" freedom: "Genuine freedom is an outstanding manifestation of the divine image in man. For God willed to leave man 'in the power of his own counsel' (cf. Sir 15:14), so that he would seek his Creator of his own accord and would freely arrive at full and blessed perfection by cleaving to God."(57) Although each individual has a right to be respected in his own journey in search of the truth, there exists a prior moral obligation, and a grave one at that, to seek the truth and to adhere to it once it is known.(58) As Cardinal John Henry Newman, that outstanding defender of the rights of conscience, forcefully put it: "Conscience has rights because it has duties."(59)

Certain tendencies in contemporary moral theology, under the influence of the currents of subjectivism and individualism just mentioned, involve novel interpretations of the relationship of freedom to the moral law, human nature and conscience, and propose novel criteria for the moral evaluation of acts. Despite their variety, these tendencies are at one in lessening or even denying the dependence of freedom on truth.

If we wish to undertake a critical discernment of these tendencies—a discernment capable of acknowledging what is legitimate, useful and of value in them, while at the same time pointing out their ambiguities, dangers and errors—we must examine them in the light of the fundamental dependence of freedom upon truth, a dependence which has found its clearest and most authoritative expression in the words of Christ: "You will know the truth, and the truth will set you free" (Jn 8:32).

I. Freedom and Law

"Of the tree of the knowledge of good and evil you shall not eat" (Gen 2:17)

35. In the Book of Genesis we read: "The Lord God commanded the man, saying, 'You may eat freely of every tree of the garden; but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall die"' (Gen 2:16-17).

With this imagery, Revelation teaches that the power to decide what is good and what is evil does not belong to man, but to God alone. The man is certainly free, inasmuch as he can understand and accept God's commands. And he possesses an extremely far reaching freedom, since he can eat "of every tree of the garden." But his freedom is not unlimited: it must halt before the "tree of the knowledge of good and evil," for it is called to accept the moral law given by God. In fact, human freedom finds its authentic and complete fulfillment precisely in the acceptance of that law. God, who alone is Good, knows perfectly what is good for man, and by virtue of his very love proposes this good to man in the commandments.

God's law does not reduce, much less do away with human freedom; rather, it protects and promotes that freedom. In contrast, however, some present-day cultural tendencies have given rise to several currents of thought in ethics which center upon an alleged conflict between freedom and law. These doctrines would grant to individuals or social groups the right to determine what is good or evil. Human freedom would thus be able to "create values" and would enjoy a primacy over truth, to the point that truth itself would be considered a creation of freedom. Freedom would thus lay claim to a moral autonomy which would actually amount to an absolute sovereignty.

36. The modern concern for the claims of autonomy has not failed to exercise an influence also in the sphere of Catholic moral theology. While the latter has certainly never attempted to set human freedom against the divine Law or to question the existence of an ultimate religious foundation for moral norms, it has, nonetheless, been led to undertake a profound rethinking about the role of reason and of faith in identifying moral norms with reference to specific "innerworldly" kinds of behavior involving oneself, others and the material world.

It must be acknowledged that underlying this work of rethinking there are certain positive concerns which to a great extent belong to the best tradition of Catholic thought. In response to the encouragement of the Second Vatican Council,(60) there has been a desire to foster dialog with modern culture, emphasizing the rational—and thus universally understandable and communicable—character of moral norms belonging to the sphere of the natural moral law.(61) There has also been an attempt to reaffirm the interior character of the ethical requirements deriving from that law, requirements which create an obligation for the will only because such an obligation was previously acknowledged by human reason and, concretely, by personal conscience.

Some people, however, disregarding the dependence of human reason on Divine Wisdom and the need, given the present state of fallen nature, for Divine Revelation as an effective means for knowing moral truths, even those of the natural order,(62) have actually posited a complete sovereignty of reason in the domain of moral norms regarding the right ordering of life in this world. Such norms would constitute the boundaries for a merely "human" morality; they would be the expression of a law which man in an autonomous manner lays down for himself and which has its source exclusively in human reason. In no way could God be considered the Author of this law, except in the sense that human reason exercises its autonomy in setting down laws by virtue of a primordial and total mandate given to man by God. These trends of thought have led to a denial, in opposition to Sacred Scripture (cf. Mt 15:3-6) and the Church's constant teaching, of the fact that the natural moral law has God as its Author, and that man, by the use of reason, participates in the eternal law, which it is not for him to establish.

37. In their desire, however, to keep the moral life in a Christian context, certain moral theologians have introduced a sharp distinction, contrary to Catholic doctrine, (63) between an ethical order, which would be human in origin and of value for this world alone, and an order of salvation, for which only certain intentions and interior attitudes regarding God and neighbor would be significant. This has then led to an actual denial that there exists, in Divine Revelation, a specific and determined moral content, universally valid and permanent. The word of God would be limited to proposing an exhortation, a generic paraenesis, which the autonomous reason alone would then have the task of completing with normative directives which are truly "objective," that is, adapted to the concrete historical situation. Naturally, an autonomy conceived in this way also involves the denial of a specific doctrinal competence on the part of the Church and her Magisterium with regard to particular moral norms which deal with the so-called "human good." Such norms would not be part of the proper content of Revelation, and would not in themselves be relevant for salvation.

No one can fail to see that such an interpretation of the autonomy of human reason involves positions incompatible with Catholic teaching.

In such a context it is absolutely necessary to clarify, in the light of the word of God and the living Tradition of the Church, the fundamental notions of human freedom and of the moral law, as well as their profound and intimate relationship. Only thus will it be possible to respond to the rightful claims of human reason in a way which accepts the valid elements present in certain currents of contemporary moral theology without compromising the Church's heritage of moral teaching with ideas derived from an erroneous concept of autonomy.

"God left man in the power of his own counsel" (Sir 15:14)

38. Taking up the words of Sirach, the Second Vatican Council explains the meaning of that "genuine freedom" which is "an outstanding manifestation of the divine image" in man: "God willed to leave man in the power of his own counsel, so that he would seek his Creator of his own accord and would freely arrive at full and blessed perfection by cleaving to God."(64) These words indicate the wonderful depth of the sharing in God's dominion to which man has been called: they indicate that man's dominion extends in a certain sense over man himself. This has been a constantly recurring theme in theological reflection on human freedom, which is described as a form of kingship. For example, Saint Gregory of Nyssa writes: "The soul shows its royal and exalted character...in that it is free and self-governed, swayed autonomously by its own will. Of whom else can this be said, save a king...? Thus human nature, created to rule other creatures, was by its likeness to the King of the universe made as it were a living image, partaking with the Archetype both in dignity and in name."(65)

The exercise of dominion over the world represents a great and responsible task for man, one which involves his freedom in obedience to the Creator's command: "Fill the earth and subdue it" (Gen 1:28). In view of this, a rightful autonomy is due to every man, as well as to the human community, a fact to which the Council's Constitution Gaudium et Spes calls special attention. This is the autonomy of earthly realities, which means that "created things have their own laws and values which are to be gradually discovered, utilized and ordered by man."(66)

39. Not only the world, however, but also man himself has been entrusted to his own care and responsibility. God left man "in the power of his own counsel" (Sir 15:14), that he might seek his Creator and freely attain perfection. Attaining such perfection means personally building up that perfection in himself. Indeed, just as man in exercising his dominion over the world shapes it in accordance with his own intelligence and will, so too in performing morally good acts, man strengthens, develops and consolidates within himself his likeness to God.

Even so, the Council warns against a false concept of the autonomy of earthly realities, one which would maintain that "created things are not dependent on God and that man can use them without reference to their Creator."(67) With regard to man himself, such a concept of autonomy produces particularly baneful effects, and eventually leads to atheism: "Without its Creator the creature simply disappears.... If God is ignored the creature itself is impoverished."(68)

40. The teaching of the Council emphasizes, on the one hand, the role of human reason in discovering and applying the moral law: the moral life calls for that creativity and originality typical of the person, the source and cause of his own deliberate acts. On the other hand, reason draws its own truth and authority from the eternal law, which is none other than divine wisdom itself.(69) At the heart of the moral life we thus find the principle of a "rightful autonomy"(70) of man, the personal subject of his actions. The moral law has its origin in God and always finds its source in him: at the same time, by virtue of natural reason, which derives from divine wisdom, it is a properly human law. Indeed, as we have seen, the natural law "is nothing other than the light of understanding infused in us by God, whereby we understand what must be done and what must be avoided. God gave this light and this law to man at creation."(71) The rightful autonomy of the practical reason means that man possesses in himself his own law, received from the Creator. Nevertheless, the autonomy of reason cannot mean that reason itself creates values and moral norms.(72) Were this autonomy to imply a denial of the participation of the practical reason in the wisdom of the divine Creator and Lawgiver, or were it to suggest a freedom which creates moral norms, on the basis of historical contingencies or the diversity of societies and cultures, this sort of alleged autonomy would contradict the Church's teaching on the truth about man.(73) It would be the death of true freedom: "But of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall die" (Gen 2:17).

41. Man's genuine moral autonomy in no way means the rejection but rather the acceptance of the moral law, of God's command: "The Lord God gave this command to the man..." (Gen 2:16). Human freedom and God's law meet and are called to intersect, in the sense of man's free obedience to God and of God's completely gratuitous benevolence towards man. Hence obedience to God is not, as some would believe, a heteronomy, as if the moral life were subject to the will of something all-powerful, absolute, extraneous to man and intolerant of his freedom. If in fact a heteronomy of morality were to mean a denial of man's self-determination or the imposition of norms unrelated to his good, this would be in contradiction to the Revelation of the Covenant and of the redemptive Incarnation. Such a heteronomy would be nothing but a form of alienation, contrary to divine wisdom and to the dignity of the human person.

Others speak, and rightly so, of theonomy, or participated theonomy, since man's free obedience to God's law effectively implies that human reason and human will participate in God's wisdom and providence. By forbidding man to "eat of the tree of the knowledge of good and evil," God makes it clear that man does not originally possess such "knowledge" as something properly his own, but only participates in it by the light of natural reason and of Divine Revelation, which manifest to him the requirements and the promptings of eternal wisdom. Law must therefore be considered an expression of divine wisdom: by submitting to the law, freedom submits to the truth of creation. Consequently one must acknowledge in the freedom of the human person the image and the nearness of God, who is present in all (cf. Eph 4:6). But one must likewise acknowledge the majesty of the God of the universe and revere the holiness of the law of God, who is infinitely transcendent: Deus semper maior.(74) Blessed is the man who takes delight in the law of the Lord (cf. Ps 1:1-2).

42. Patterned on God's freedom, man's freedom is not negated by his obedience to the divine law; indeed, only through this obedience does it abide in the truth and conform to human dignity. This is clearly stated by the Council: "Human dignity requires man to act through conscious and free choice, as motivated and prompted personally from within, and not through blind internal impulse or merely external pressure. Man achieves such dignity when he frees himself from all subservience to his feelings, and in a free choice of the good, pursues his own end by effectively and assiduously marshaling the appropriate means."(75)

In his journey towards God, the One who "alone is good," man must freely do good and avoid evil. But in order to accomplish this he must be able to distinguish good from evil. And this takes place above all thanks to the light of natural reason, the reflection in man of the splendor of God's countenance. Thus Saint Thomas, commenting on a verse of Psalm 4, writes: "After saying: Offer right sacrifices (Ps 4:5), as if some had then asked him what right works were, the Psalmist adds: There are many who say: Who will make us see good ? And in reply to the question he says: The light of your face, Lord, is signed upon us, thereby implying that the light of natural reason whereby we discern good from evil, which is the function of the natural law, is nothing else but an imprint on us of the divine light."(76) It also becomes clear why this law is called the natural law: it receives this name not because it refers to the nature of irrational beings but because the reason which promulgates it is proper to human nature."(77)

43. The Second Vatican Council points out that the "supreme rule of life is the divine law itself, the eternal, objective and universal law by which God out of his wisdom and love arranges, directs and governs the whole world and the paths of the human community. God has enabled man to share in this divine law, and hence man is able under the gentle guidance of God's providence increasingly to recognize the unchanging truth."(78)

The Council refers to the classic teaching on God's eternal law. Saint Augustine defines this as "the reason or the will of God, who commands us to respect the natural order and forbids us to disturb it."(79) Saint Thomas identifies it with "the type of the divine wisdom as moving all things to their due end."(80) And God's wisdom is providence, a love which cares. God himself loves and cares, in the most literal and basic sense, for all creation (cf. Wis 7:22; 8:11). But God provides for man differently from the way in which he provides for beings which are not persons. He cares for man not "from without," through the laws of physical nature, but "from within," through reason, which, by its natural knowledge of God's eternal law, is consequently able to show man the right direction to take in his free actions.(81) In this way God calls man to participate in his own providence, since he desires to guide the world—not only the world of nature but also the world of human persons—through man himself, through man's reasonable and responsible care. The natural law enters here as the human expression of God's eternal law. Saint Thomas writes: "Among all others, the rational creature is subject to divine providence in the most excellent way, insofar as it partakes of a share of providence, being provident both for itself and for others. Thus it has a share of the Eternal Reason, whereby it has a natural inclination to its proper act and end. This participation of the eternal law in the rational creature is called natural law."(82)

44. The Church has often made reference to the Thomistic doctrine of natural law, including it in her own teaching on morality. Thus my Venerable Predecessor Leo XIII emphasized the essential subordination of reason and human law to the Wisdom of God and to his law. After stating that "the natural law is written and engraved in the heart of each and every man, since it is none other than human reason itself which commands us to do good and counsels us not to sin," Leo XIII appealed to the "higher reason" of the divine Lawgiver: "But this prescription of human reason could not have the force of law unless it were the voice and the interpreter of some higher reason to which our spirit and our freedom must be subject." Indeed, the force of law consists in its authority to impose duties, to confer rights and to sanction certain behavior: "Now all of this, clearly could not exist in man if, as his own supreme legislator, he gave himself the rule of his own actions." And he concluded: "It follows that the natural law is itself the eternal law, implanted in beings endowed with reason, and inclining them towards their right action and end; it is none other than the eternal reason of the Creator and Ruler of the universe."(83)

Man is able to recognize good and evil thanks to that discernment of good from evil which he himself carries out by his reason, in particular by his reason enlightened by Divine Revelation and by faith, through the law which God gave to the Chosen People, beginning with the commandments on Sinai. Israel was called to accept and to live out God's law as a particular gift and sign of its election and of the divine Covenant, and also as a pledge of God's blessing. Thus Moses could address the children of Israel and ask them: "What great nation is there that has a god so near to it as the Lord our God is to us, whenever we call upon him? And what great nation is there that has statutes and ordinances so righteous as all this law which I set before you this day?" (Dt 4:7-8). In the Psalms we encounter the sentiments of praise, gratitude and veneration which the Chosen People is called to show towards God's law, together with an exhortation to know it, ponder it and translate it into life. "Blessed is the man who walks not in the counsel of the wicked, nor stands in the way of sinners, nor sits in the seat of scoffers, but his delight is in the law of the Lord and on his law he meditates day and night" (Ps 1:1-2). "The law of the Lord is perfect, reviving the soul; the testimony of the Lord is sure, making wise the simple; the precepts of the Lord are right, rejoicing the heart; the commandment of the Lord is pure, enlightening the eyes" (Ps 18/19:8-9).

45. The Church gratefully accepts and lovingly preserves the entire deposit of Revelation, treating it with religious respect and fulfilling her mission of authentically interpreting God's law in the light of the Gospel. In addition, the Church receives the gift of the New Law, which is the "fulfillment" of God's law in Jesus Christ and in his Spirit. This is an "interior" law (cf. Jer 31:31-33), "written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts" (2 Cor 3:3); a law of perfection and of freedom (cf. 2 Cor 3:17); "the law of the Spirit of life in Christ Jesus" (Rom 8:2). Saint Thomas writes that this law "can be called law in two ways. First, the law of the spirit is the Holy Spirit...who, dwelling in the soul, not only teaches what it is necessary to do by enlightening the intellect on the things to be done, but also inclines the affections to act with uprightness.... Second, the law of the spirit can be called the proper effect of the Holy Spirit, and thus faith working through love (cf. Gal 5:6), which teaches inwardly about the things to be done...and inclines the affections to act."(84)

Even if moral–theological reflection usually distinguishes between the positive or revealed law of God and the natural law, and, within the economy of salvation, between the "old" and the "new" law, it must not be forgotten that these and other useful distinctions always refer to that law whose author is the one and the same God and which is always meant for man. The different ways in which God, acting in history, cares for the world and for mankind are not mutually exclusive; on the contrary, they support each other and intersect. They have their origin and goal in the eternal, wise and loving counsel whereby God predestines men and women "to be conformed to the image of his Son" (Rom 8:29). God's plan poses no threat to man's genuine freedom; on the contrary, the acceptance of God's plan is the only way to affirm that freedom.

"What the law requires is written on their hearts" (Rom 2-15)

46. The alleged conflict between freedom and law is forcefully brought up once again today with regard to the natural law, and particularly with regard to nature. Debates about nature and freedom have always marked the history of moral reflection; they grew especially heated at the time of the Renaissance and the Reformation, as can be seen from the teaching of the Council of Trent.(85) Our own age is marked, though in a different sense, by a similar tension. The penchant for empirical observation, the procedures of scientific objectification, technological progress and certain forms of liberalism have led to these two terms being set in opposition, as if a dialectic, if not an absolute conflict, between freedom and nature were characteristic of the structure of human history. At other periods, it seemed that "nature" subjected man totally to its own dynamics and even its own unbreakable laws. Today too, the situation of the world of the senses within space and time, physio-chemical constants, bodily processes, psychological impulses and forms of social conditioning seem to many people the only really decisive factors of human reality. In this context even moral facts, despite their specificity, are frequently treated as if they were statistically verifiable data, patterns of behavior which can be subject to observation or explained exclusively in categories of psychosocial processes, As a result, some ethicists, professionally engaged in the study of human realities and behavior, can be tempted to take as the standard for their discipline and even for its operative norms the results of a statistical study of concrete human behavior patterns and the opinions about morality encountered in the majority of people.

Other moralists, however, in their concern to stress the importance of values, remain sensitive to the dignity of freedom, but they frequently conceive of freedom as somehow in opposition to or in conflict with material and biological nature, over which it must progressively assert itself. Here various approaches are at one in overlooking the created dimension of nature and in misunderstanding its integrity. For some, "nature" becomes reduced to raw material for human activity and for its power: thus nature needs to be profoundly transformed, and indeed overcome by freedom, inasmuch as it represents a limitation and denial of freedom. For others, it is in the untrammeled advancement of man's power, or of his freedom, that economic, cultural, social and even moral values are established: nature would thus come to mean everything found in man and the world apart from freedom. In such an understanding, nature would include in the first place the human body, its make-up and its processes: against this physical datum would be opposed whatever is "constructed," in other words "culture," seen as the product and result of freedom. Human nature, understood in this way, could be reduced to and treated as a readily available biological or social material. This ultimately means making freedom self-defining and a phenomenon creative of itself and its values. Indeed, when all is said and done man would not even have a nature; he would be his own personal life-project. Man would be nothing more than his own freedom!

47. In this context, objections of physicalism and naturalism0 have been leveled against the traditional conception of the natural law, which is accused of presenting as moral laws what are in themselves mere biological laws. Consequently, in too superficial a way, a permanent and unchanging character would be attributed to certain kinds of human behavior, and, on the basis of this, an attempt would be made to formulate universally valid moral norms. According to certain theologians, this kind of "biologistic or naturalistic argumentation" would even be present in certain documents of the Church's Magisterium, particularly those dealing with the area of sexual and conjugal ethics. It was, they maintain, on the basis of a naturalistic understanding of the sexual act that contraception, direct sterilization, autoeroticism, pre-marital sexual relations, homosexual relations and artificial insemination were condemned as morally unacceptable. In the opinion of these same theologians, a morally negative evaluation of such acts fails to take into adequate consideration both man's character as a rational and free being and the cultural conditioning of all moral norms. In their view, man, as a rational being, not only can but actually must freely determine the meaning of his behavior. This process of "determining the meaning" would obviously have to take into account the many limitations of the human being, as existing in a body and in history. Furthermore, it would have to take into consideration the behavioral models and the meanings which the latter acquire in any given culture. Above all, it would have to respect the fundamental commandment of love of God and neighbor. Still, they continue, God made man as a rationally free being; he left him "in the power of his own counsel" and he expects him to shape his life in a personal and rational way. Love of neighbor would mean above all and even exclusively respect for his freedom to make his own decisions. The workings of typically human behavior, as well as the so-called "natural inclinations," would establish at the most–so they say–general orientation towards correct behavior, but they cannot determine the moral assessment of individual human acts, so complex from the viewpoint of situations.

48. Faced with this theory, one has to consider carefully the correct relationship existing between freedom and human nature, and in particular the place of the human body in questions of natural law.

A freedom which claims to be absolute ends up treating the human body as a raw datum, devoid of any meaning and moral values until freedom has shaped it in accordance with its design. Consequently, human nature and the body appear as presuppositions or preambles, materially necessary, for freedom to make its choice, yet extrinsic to the person, the subject and the human act. Their functions would not be able to constitute reference points for moral decisions, because the finalities of these inclinations would be merely "physical" goods, called by some "pre-moral." To refer to them, in order to find in them rational indications with regard to the order of morality, would be to expose oneself to the accusation of physicalism or biologism. In this way of thinking, the tension between freedom and a nature conceived of in a reductive way is resolved by a division within man himself.

This moral theory does not correspond to the truth about man and his freedom. It contradicts the Church's teachings on the unity of the human person, whose rational soul is per se et essentialiter the form of his body.(86) The spiritual and immortal soul is the principle of unity of the human being, whereby it exists as a whole—corpore et anima unus(87)—as a person. These definitions not only point out that the body, which has been promised the resurrection, will also share in glory. They also remind us that reason and free will are linked with all the bodily and sense faculties. The person, including the body, is completely entrusted to himself, and it is in the unity of body and soul that the person is the subject of his own moral acts. The person, by the light of reason and the support of virtue, discovers in the body the anticipatory signs, the expression and the promise of the gift of self, in conformity with the wise plan of the Creator. It is in the light of the dignity of the human person—dignity which must be affirmed for its own sake—that reason grasps the specific moral value of certain goods towards which the person is naturally inclined. And since the human person cannot be reduced to a freedom which is self-designing, but entails a particular spiritual and bodily structure, the primordial moral requirement of loving and respecting the person as an end and never as a mere means also implies, by its very nature, respect for certain fundamental goods, without which one would fall into relativism and arbitrariness.

49. A doctrine which dissociates the moral act from the bodily dimensions of its exercise is contrary to the teaching of Scripture and Tradition. Such a doctrine revives, in new forms, certain ancient errors which have always been opposed by the Church, inasmuch as they reduce the human person to a "spiritual" and purely formal freedom. This reduction misunderstands the moral meaning of the body and of kinds of behavior involving it (cf. 1 Cor 6:19). Saint Paul declares that "the immoral, idolaters, adulterers, sexual perverts, thieves, the greedy, drunkards, revilers, robbers" are excluded from the Kingdom of God (cf. 1 Cor 6:9). This condemnation—repeated by the Council of Trent—(88) lists as "mortal sins" or "immoral practices" certain specific kinds of behavior the willful acceptance of which prevents believers from sharing in the inheritance promised to them.

In fact, body and soul are inseparable: in the person, in the willing agent and in the deliberate act they stand or fall together.

50. At this point the true meaning of the natural law can be understood: it refers to man's proper and primordial nature, the "nature of the human person,"(89) which is the person himself in the unity of soul and body, in the unity of his spiritual and biological inclinations and of all the other specific characteristics necessary for the pursuit of his end. "The natural moral law expresses and lays down the purposes, rights and duties which are based upon the bodily and spiritual nature of the human person. Therefore this law cannot be thought of as simply a set of norms on the biological level; rather it must be defined as the rational order whereby man is called by the Creator to direct and regulate his life and actions and in particular to make use of his own body."(90) To give an example, the origin and the foundation of the duty of absolute respect for human life are to be found in the dignity proper to the person and not simply in the natural inclination to preserve one's own physical life. Human life, even though it is a fundamental good of man, thus acquires a moral significance in reference to the good of the person, who must always be affirmed for his own sake. While it is always morally illicit to kill an innocent human being, it can be licit, praiseworthy or even imperative to give up one's own life (cf. Jn 15:13) out of love of neighbor or as a witness to the truth. Only in reference to the human person in his "unified totality," that is, as "a soul which expresses itself in a body and a body informed by an immortal spirit,"(91) can the specifically human meaning of the body be grasped. Indeed, natural inclinations take on moral relevance only insofar as they refer to the human person and his authentic fulfillment, a fulfillment which for that matter can take place always and only in human nature. By rejecting all manipulations of corporeity which alter its human meaning, the Church serves man and shows him the path of true love, the only path on which he can find the true God.

The natural law thus understood does not allow for any division between freedom and nature. Indeed, these two realities are harmoniously bound together, and each is intimately linked to the other.

"From the beginning it was not so" (Mt 19:8)

51. The alleged conflict between freedom and nature also has repercussions on the interpretation of certain specific aspects of the natural law, especially its universality and immutability. "Where then are these rules written," Saint Augustine wondered, "except in the book of that light which is called truth? From thence every just law is transcribed and transferred to the heart of the man who works justice, not by wandering but by being, as it were, impressed upon it, just as the image from the ring passes over to the wax, and yet does not leave the ring."(92)

Precisely because of this "truth" the natural law involves universality. Inasmuch as it is inscribed in the rational nature of the person, it makes itself felt to all beings endowed with reason and living in history. In order to perfect himself in his specific order, the person must do good and avoid evil, be concerned for the transmission and preservation of life, refine and develop the riches of the material world, cultivate social life, seek truth, practice good and contemplate beauty.(93)

The separation which some have posited between the freedom of individuals and the nature which all have in common—as it emerges from certain philosophical theories which are highly influential in present-day culture—obscures the perception of the universality of the moral law on the part of reason. But inasmuch as the natural law expresses the dignity of the human person and lays the foundation for his fundamental rights and duties, it is universal in its precepts and its authority extends to all mankind. This universality does not ignore the individuality of human beings, nor is it opposed to the absolute uniqueness of each person. On the contrary, it embraces at its root each of the person's free acts, which are meant to bear witness to the universality of the true good. By submitting to the common law, our acts build up the true communion of persons and, by God's grace, practice charity, "which binds everything together in perfect harmony" (Col 3:14). When on the contrary they disregard the law, or even are merely ignorant of it, whether culpably or not, our acts damage the communion of persons, to the detriment of each.

52. It is right and just, always and for everyone, to serve God, to render him the worship which is his due and to honor one's parents as they deserve. Positive precepts such as these, which order us to perform certain actions and to cultivate certain dispositions, are universally binding; they are "unchanging."(94) They unite in the same common good all people of every period of history, created for "the same divine calling and destiny."(95) These universal and permanent laws correspond to things known by the practical reason and are applied to particular acts through the judgment of conscience. The acting subject personally assimilates the truth contained in the law. He appropriates this truth of his being and makes it his own by his acts and the corresponding virtues. The negative precepts of the natural law are universally valid. They oblige each and every individual, always and in every circumstance. It is a matter of prohibitions which forbid a given action semper et pro semper, without exception, because the choice of this kind of behavior is in no case compatible with the goodness of the will of the acting person, with his vocation to life with God and to communion with his neighbor. It is prohibited—to everyone and in every case—to violate these precepts. They oblige everyone, regardless of the cost, never to offend in anyone, beginning with oneself, the personal dignity common to all.

On the other hand, the fact that only the negative commandments oblige always and under all circumstances does not mean that in the moral life prohibitions are more important than the obligation to do good indicated by the positive commandments. The reason is this: the commandment of love of God and neighbor does not have in its dynamic any higher limit, but it does have a lower limit, beneath which the commandment is broken. Furthermore, what must be done in any given situation depends on the circumstances, not all of which can be foreseen; on the other hand there are kinds of behavior which can never, in any situation, be a proper response—a response which is in conformity with the dignity of the person. Finally, it is always possible that man, as the result of coercion or other circumstances, can be hindered from doing certain good actions; but he can never be hindered from not doing certain actions, especially if he is prepared to die rather than to do evil.

The Church has always taught that one may never choose kinds of behavior prohibited by the moral commandments expressed in negative form in the Old and New Testaments. As we have seen, Jesus himself reaffirms that these prohibitions allow no exceptions: "If you wish to enter into life, keep the commandments.... You shall not murder, You shall not commit adultery, You shall not steal, You shall not bear false witness" (Mt 19:17-18).

53. The great concern of our contemporaries for historicity and for culture has led some to call into question the immutability of the natural law itself, and thus the existence of "objective norms of morality" (96) valid for all people of the present and the future, as for those of the past. Is it ever possible, they ask, to consider as universally valid and always binding certain rational determinations established in the past, when no one knew the progress humanity would make in the future?

It must certainly be admitted that man always exists in a particular culture, but it must also be admitted that man is not exhaustively defined by that same culture. Moreover, the very progress of cultures demonstrates that there is something in man which transcends those cultures. This "something" is precisely human nature: this nature is itself the measure of culture and the condition ensuring that man does not become the prisoner of any of his cultures, but asserts his personal dignity by living in accordance with the profound truth of his being. To call into question the permanent structural elements of man which are connected with his own bodily dimension would not only conflict with common experience, but would render meaningless Jesus' reference to the "beginning, " precisely where the social and cultural context of the time had distorted the primordial meaning and the role of certain moral norms (cf. Mt 19:1-9). This is the reason why "the Church affirms that underlying so many changes there are some things which do not change and are ultimately founded upon Christ, who is the same yesterday and today and for ever."(97) Christ is the "Beginning" who, having taken on human nature, definitively illumines it in its constitutive elements and in its dynamism of charity towards God and neighbor.(98)

Certainly there is a need to seek out and to discover the most adequate formulation for universal and permanent moral norms in the light of different cultural contexts, a formulation most capable of ceaselessly expressing their historical relevance, of making them understood and of authentically interpreting their truth. This truth of the moral law—like that of the "deposit of faith"—unfolds down the centuries: the norms expressing that truth remain valid in their substance, but must be specified and determined "eodem sensu eademque sententia"(99) in the light of historical circumstances by the Church's Magisterium, whose decision is preceded and accompanied by the work of interpretation and formulation characteristic of the reason of individual believers and of theological reflection.(100)

II. Conscience and Truth

Man's sanctuary

54. The relationship between man's freedom and God's law is most deeply lived out in the "heart" of the person, in his moral conscience. As the Second Vatican Council observed: "In the depths of his conscience man detects a law which he does not impose on himself, but which holds him to obedience. Always summoning him to love good and avoid evil, the voice of conscience can when necessary speak to his heart more specifically: 'do this, shun that.' For man has in his heart a law written by God. To obey it is the very dignity of man; according to it he will be judged (cf. Rom2:14-16)."(101)

The way in which one conceives the relationship between freedom and law is thus intimately bound up with one's understanding of the moral conscience. Here the cultural tendencies referred to above—in which freedom and law are set in opposition to each another and kept apart, and freedom is exalted almost to the point of idolatry—lead to a "creative" understanding of moral conscience, which diverges from the teaching of the Church's tradition and her Magisterium.

55. According to the opinion of some theologians, the function of conscience had been reduced, at least at a certain period in the past, to a simple application of general moral norms to individual cases in the life of the person. But those norms, they continue, cannot be expected to foresee and to respect all the individual concret
