Life
Gregory was born at Arianzus near Nazianzus in Cappadocia, where his father was bishop. He studied at Caesarea in Cappadocia, Caesarea in Palestine, Alexandria and Athens; at Athens he renewed his friendship with Basil.
His father, by then bishop, overcame Gregory’s reluctance and had him ordained priest. He was consecrated about 372 by Basil, much against his will, as bishop of Sasima, a see Basil had created; he never took possession of it, and the episode strained their friendship. He assisted his father at Nazianzus until his father’s death in 374.
In 379 he went to Constantinople to lead the small community there that held to the faith of Nicaea, preaching in a private house he called the Anastasia (“Resurrection”). There he delivered the five orations on the Trinity that gave him the name “the Theologian”.
At the Council of Constantinople in 381 he was recognised as bishop of the city and for a time presided over the council, but faced with opposition, and in poor health, he resigned after a few months. He returned to Cappadocia, wrote much of his poetry, including his verse autobiography, and died at Arianzus in 389 or 390.
Principal written sources
- His 45 orations, including the five Theological Orations (27–31) and the funeral oration for Basil (43).
- Letters, and poems including the autobiographical On His Own Life (De vita sua).
