The Nicene Age

Who Caesarius of Nazianzus was

Younger brother of Gregory the Theologian, a brilliant physician trained at Alexandria who rose to be chief doctor at the imperial court in Constantinople — remarkably keeping his post even under Julian the Apostate, who tried and failed to win him back to paganism. He survived an earthquake at Nicaea that his brother read as a divine summons, was baptized late, and died soon after, leaving his estate to the poor. Gregory’s funeral oration for him is a meditation on a Christian who served at the heart of a pagan-leaning court without losing his faith.
