Augustine

Early Christian church father and philosopher who served (396-430) as the bishop of Hippo (in present-day Algeria). Through such writings as the autobiographical Confessions (397) and the voluminous City of God (413-426), he profoundly influenced Christianity, arguing against Manicheanism and Donatism and helping to establish the doctrine of original sin.

Italian-born missionary and prelate who introduced Christianity to southern Britain and in 597 was ordained as the first archbishop of Canterbury.
