A Church Father’s theological citadel. Aurelius Augustine (AD 354–430), one of the most important figures in the development of western Christianity and philosophy, was the son of a pagan, Patricius of Tagaste, and his Christian wife, Monnica. While studying to become a rhetorician, he plunged into a turmoil of philosophical and psychological doubts, leading him to Manichaeism. In 383 he moved to Rome and then Milan to teach rhetoric. Despite exploring classical philosophical systems, especially skepticism and Neoplatonism, his studies of Paul’s letters with his friend Alypius, and the preaching of Bishop Ambrose, led in 386 to his momentous conversion from mixed beliefs to Christianity. He soon returned to Tagaste and founded a religious community, and in 395 or 396 became bishop of Hippo. From Augustine’s large output the Loeb Classical Library offers that great autobiography the Confessions (in two volumes); On the City of God (seven volumes), which unfolds God’s action in the progress of the world’s history, and propounds the superiority of Christian beliefs over pagan in adversity; and a selection of Letters which are important for the study of ecclesiastical theologians.
