Saint Athanasius, pillar of Orthodoxy and Father of the Church, was born in Alexandria in 275, to pious Christian parents. Even as a child, his piety and devotion to the Faith were so notable that Alexander, the Patriarch of the city, took Athanasius under his protection.

With St Athanasius, the Church commemorates St Cyril (Kyrillos), also Archbishop of Alexandria (412-44). His lot was to defend the Faith against the heretic Nestorius, Patriarch of Constantinople, who denied that Christ in his Incarnation truly united the divine with the human nature. Cyril attempted in private correspondence to restore Nestorius to the Christian faith, and when this failed he, along with Pope Celestine of Rome, led the defense of Orthodoxy against Nestorius’ teaching.
