Saint Augustine (354–430) was bishop of Hippo and one of the Latin Fathers of the Church. Born in Tagaste, Numidia, he studied in Carthage and taught rhetoric in Carthage and Milan. His career eventually collapsed, and he became a clergyman in Hippo, where he remained for the rest of his life. He became bishop of Hippo in 395 or 396. Arguably the most significant Christian philosopher of antiquity, Augustine adapted classical thought into Christian teachings. His many sermons, writings, and books, including Confessions and The City of God, helped lay the foundations of modern Christian thought.
