To Anfilochius, Bishop of Iconia:
She who has intentionally destroyed [the fetus] is subject to the penalty corresponding to a homicide. For us, there is no scrutinizing between the formed and unformed [fetus]; here truly justice is made not only for the unborn but also with reference to the person who is attentive only to himself/herself since so many women generally die for this very reason.
-First Letter 2
Let her that procures abortion undergo ten years' penance, whether the embryo were perfectly formed, or not.
- The First Canonical Epistle of Our Holy Father Basil, Archbishop of Caesarea in Cappadocia to Amphilochius, Bishop of Iconium.
…those who give the abortifacients and those who take the poisons are guilty of homicide.
-First Letter 8
