This doctor of the church, famous for his understanding of and writing about the Incarnation, became bishop of his hometown, Alexandria, Egypt, when he was in his early 30s. As metropolitan patriarch for 45 years, he fought the heresy of Arius, a well-educated Alexandrian priest; ran afoul of three emperors and was exiled multiple times; and defended church unity despite long-standing difficulties with other bishops.
