... I gave as an offering my all to Him Who had won me and saved me, my property, my fame, my health, my very words... In considering all these things, I preferred Christ. And the words of God were made sweet as honeycombs to me, and I cried after knowledge and lifted up my voice for wisdom. There was moreover the moderation of anger, the curbing of the tongue, the restraint of the eyes, the discipline of the belly, and the trampling under foot of the glory which clings to the earth.
Gregory of NazianzusMore Gregory of Nazianzus quotes
If 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.
Gregory of Nazianzus
