Gregory of Nazianzus

Gregory of Nazianzus — called in the East simply “the Theologian” — was one of the three Cappadocian Fathers and, briefly, archbishop of Constantinople. A shy and bookish man happier in retirement than in office, he was nonetheless the finest orator of the Greek Church; his Five Theological Orations, preached at Constantinople as Arianism was collapsing, did more than any other writing to fix the language of the doctrine of the Trinity. He presided for a time over the First Council of Constantinople in 381 before resigning to return to a quiet life.
