These three things God requires of all the Baptized: right faith in the heart, truth on the tongue, temperance in the body.
Gregory of NazianzusThe Godhead is, to speak concisely, undivided there is one mingling of Light, as it were of three suns joined to each other.
Gregory of NazianzusWhat He was, He laid aside; what He was not, He assumed. He takes upon Himself the poverty of my flesh so that I may receive the riches of His divinity.
Gregory of NazianzusIf anyone does not believe that Holy Mary is the Mother of God, he is severed from the Godhead. If anyone should assert that He passed through the Virgin as through a channel, and was not at once divinely and humanly formed in her (divinely, because without the intervention of a man; humanly, because in accordance with the laws of gestation), he is in like manner godless.
