A.D. 431
“This was the sentiment of the holy Fathers; therefore they ventured to call the Holy Virgin, the Mother of God, not as if the nature of the Word or his divinity had its beginning from the Holy Virgin, but because of her was born that holy body with a rational soul, to which the Word being personally united is said to be born according to the flesh.”
Letter to Nestorius, read at the Council of Ephesus
