Some Christian join skeptics on this point. They doubt Matthew’s claim about Mary: “While she was sill a virgin, she became pregnant through the power of the Holy Spirit” (Matthew 1:18).
Matthew says this fulfills prophecy: “The virgin will conceive a child!” (Isaiah 7:14). But virgin in Hebrew-Isaiah’s language-can mean “young woman”or “virgin.” In either case, Isaiah wasn’t talking about a pregnant virgin.
He was talking about a specific woman in his time, perhaps someone the king was about to marry. This young woman would soon get pregnant-the normal way-and have a son. And by the time this boy was old enough to eta solid food, two nations threatening the Jewish kingdom would be destroyed. So the son was a sign.
Matthew sees the prophecy as a sign for his time, 700 years after Isaiah. The Greek word that Matthew uses for “virgin” means just that-a woman who hasn’t had sex. Perhaps Matthew gets this insight from Jesus. But he doesn’t say.
Early Christians came to accept the teaching literally. They saw it as a miraculous expression of an unsolved mystery-evidence supporting the Christian teaching that Jesus is fully human and family God.
