If Jesus teas born of a virgin why does He say nothing about it?

The Catholic Answers

We do not know that He said nothing about it. The evangelists do not record any special utterances of Christ on this subject, but they do not pretend to record all that He ever said. St Luke tells us that when He met the two disciples on the way to Emmaus, “beginning at Moses and all the prophets, he expounded to them in all the Scriptures, the things that were concerning him.” XXIV., 27. There is every probability that He explained His advent into this world according to the prophecy of Isaiah. Meantime the Gospels do record the fact that Mary was a virgin, and their words are as reliable in this as when they record the utterances of Christ.
