And if they say that she who conceived is called not a virgin but a young woman in Scripture (for so it is said it is explained among them) what worthy sign of the promise of God, we answer, would this be, if like all women after union with a man a young woman were naturally to conceive? And how could he that were born of her be God? And not simply God, but "God with us"? For that is the meaning of Emmanuel, which name it says the child is to be called. "For behold a virgin," it says, "shall conceive (316) and bear a son, and thou shalt call his name Emmanuel, which is interpreted God with us." Where would be God's struggle, where His labour and difficulty, if a woman were to bring forth in the accustomed manner?
