Life

Athanasius was born around 296 in Alexandria, the great Christian and Greek city of Roman Egypt. As a boy — the story is well attested — he played at "baptizing" his friends on the seashore with such gravity that the Patriarch Alexander, watching from a window, sent for the children and decided the boy was destined for the Church. He was educated in the catechetical school of Alexandria under Alexander's tutelage, ordained deacon by him, and served at his side at the First Ecumenical Council at Nicaea in 325, where Athanasius — not yet thirty — was the most penetrating opponent of Arius.

In 328, on Alexander's death, the people of Alexandria carried Athanasius into the cathedral and acclaimed him bishop. He was thirty-three. For the next forty-five years he held the see through five separate exiles totaling seventeen years away from it — driven out four times by Arian emperors (Constantine the Great, Constantius II twice, Julian the Apostate, Valens) and once by an imperial commission. Three times he was sentenced to death and three times escaped. He went into hiding in the Egyptian desert with Anthony's monks and in the cellars of his own city; he went on writing the whole time.

His writings shaped the Christology of the entire later Church. On the Incarnation, written in his twenties, contains the famous sentence "The Word became man that we might become god" — the heart of the Orthodox doctrine of theosis. Against the Arians, in four books, gave the East the vocabulary it needed for the Trinity. His Life of Anthony, written in his seventies, single-handedly created the Western monastic tradition; Augustine of Hippo at Milan wept over it and through it was converted.

He reposed in his own city, finally at peace under the Emperor Valens's brief truce, on May 2, 373. He had spent his whole adult life defending the consubstantiality of the Son with the Father. The Church gave him his title — Athanasius the Great — almost at once, and reckons him among the four great doctors of the Eastern tradition together with Basil, the two Gregories, and Chrysostom.
