The familiar Christmas story, including the virgin conception and birth of Jesus, is found in the gospels of Matthew and Luke. Scholars have pointed out that these stories are somewhat disconnected from other parts of these Gospels and the rest of the New Testament. In fact, by the time he is a young boy in the temple, Jesus’s parents seem to have forgotten the virgin birth. They act surprised by his odd behavior. There is never any other mention in the New Testament of these incredible events! These stories seem to be an afterthought, written later than the rest of the gospels that contain them. To make matters more interesting, the stories themselves have inconsistencies and ambiguities – contradictory genealogies, for example. Our Christmas story (singular) is actually a composite.
Or consider the idea that Mary is a virgin. The Greek writer of Matthew quotes Isaiah as saying: “a parthenos shall conceive and bear a child.” The Hebrew word in Isaiah is “almah,” which means simply “young woman.” But the Greek word parthenos can mean either a virgin or a young woman, and it got translated as “virgin.” Modern Bible translations have corrected this, but it is a central part of the Christmas story.
