St. Cyril of Alexandria: "The virgin mother"

“CHRIST, as I have said, was also God in his humanity, permitting human nature to use its laws while nonetheless conserving also the purity of divinity. For in this way and in no other is God to be understood both what was born by nature and those things which the virgin mother produced not only of flesh and blood in the same way that other mothers do, but the flesh and blood of the Lord and of God imbued with our likeness.”

~St. Cyril of Alexandria: Pascal Homilies, 17: 2.
