Quote: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.
