Augustine of Hippo
Aurelius Augustinus, Augustine of Hippo, or Saint Augustine (November 13, 354–August 28, 430) was one of the most important figures in the development of Western Christianity. In Roman Catholicism, he is a saint and pre-eminent Doctor of the Church. Many Protestants, especially Calvinists, consider him to be one of the theological fountainheads of Reformation teaching on salvation and grace. Born in Africa as the eldest son of Saint Monica, he was educated and baptized in Italy. His works—including The Confessions, which is often called the first Western autobiography—are still read by Christians around the world.
