Our Triune God

“Be reconciled to God (2 Cor 5:20) and do not quench the Spirit (1 Thess 5:19); or rather may Christ be reconciled to you, and may the Spirit enlighten you. But if you are too fond of your quarrel, we at any rate will hold fast to the Trinity, and by the Trinity may we be saved” (Gregory the Theologian, Oration, 29:21, PG 36.104A-B).
