The Ninth and Tenth Commandments forbid us to covet what belongs to our neighbor, whether it be his spouse or his possessions. This commandment, in other words, requires us to limit our desires by respecting the boundaries between what is ours and what isn’t.
That is a sacred boundary that is completely shattered by abortion. The boundary between what is the mother’s and what is the child’s completely disappears. Some, for instance, will justify abortion because the mother has to get on with her life. But so does the child.
Some will justify it because the mother has freedom not to be burdened. But so does the child. And in denying that the child has the same freedom she claims to have, she destroys the meaning and foundation of her own.
