Now Gabriel means “strength of God.” Rightly he shone forth with such a name, since by his testimony he bore witness to the coming birth of God in the flesh. The prophet said this in the psalm, “The Lord strong and powerful, the Lord powerful in battle”—that battle, undoubtedly, in which he [Christ] came to fight “the powers of the air” and to snatch the world from their tyranny.
Truly full of grace was she to whom it was granted to give birth to Jesus Christ, the very one through whom grace and truth came. And so the Lord was truly with her whom he first raised up from earthly to heavenly desires, in an unheard of love of chastity, and afterwards sanctified, by means of his human nature, with all the fullness of his divinity. Truly blessed among women was she who without precedent in the womanly state rejoiced in having the honor of parenthood along with the beauty of virginity, inasmuch as it was fitting that a virgin mother bring forth God the Son.
