Answer to the Pelagians, IV

What we call the Pelagian heresy actually took many forms, and had multiple proponents at different stages before it was officially condemned. Augustine, as bishop of Hippo, saw that these teachings were dangerous and set out to address them by explaining the true Church doctrine on these subjects. He first denounced the heresies verbally, in sermons and conferences. When a friend asked him to clarify the Christian doctrines contradicted by certain heresies, Augustine wrote down his rebuttal at length. Over time he wrote nearly a dozen distinct texts in direct answer to the various Pelagian heresies.
