Athanasius of Alexandria


Abélard's tract regarding the power of God to create Himself was one of the many distant echoes of the great Arian-Athanasian controversy of the fourth century. St. Athanasius, bishop of Alexandria, well deserved the title conferred on him by the Church as "the father of orthodoxy," and it was by his name that the doctrine of identity of substance ("the Son is of the same substance with the Father") became known. Much of the life of Athanasius was passed amid persecutions at the hands of his enemies, and on several occasions he was driven into exile.
