St. Augustine (354-430 CE) reversed centuries of Christian teaching in Western Europe, by returning to the Aristotelian Pagan concept of " delayed ensoulment. " He wrote 7 that a human soul cannot live in an unformed body. Thus, early in pregnancy, an abortion is not murder because no soul is destroyed (or, more accurately, only a vegetable or animal soul is terminated). He wrote extensively on sexual matters, teaching that the original sin of Adam and Eve are passed to each successive generation through the pleasure generated during sexual intercourse. This passed into the church's canon law. Only abortion of a more fully developed " fetus animatus " (animated fetus) was punished as murder.
