“The historical problems with Luke are even more pronounced. For one thing, we have relatively good records for the reign of Caesar Augustus, and there is no mention anywhere in any of them of an empire-wide census for which everyone had to register by returning to their ancestral home. And how could such a thing even be imagined? Joesph returns to Bethlehem because his ancestor David was born there. But David lived a thousand years before Joseph. Are we to imagine that everyone in the Roman Empire was required to return to the homes of their ancestors from a thousand years earlier? If we had a new worldwide census today and each of us had to return to the towns of our ancestors a thousand years back—where would
you go? Can you imagine the total disruption of human life that this kind of universal exodus would require? And can you imagine that such a project would never be mentioned in any of the newspapers? There is not a single reference to any such census in any ancient source, apart from Luke. Why then does Luke say there was such a census? The answer may seem obvious to you. He wanted Jesus to be born in Bethlehem, even though he knew he came from Nazareth ... there is a prophecy in the Old Testament book of Micah that a savior would come from Bethlehem. What were these Gospel writer to do with the fact that it was widely known that Jesus came from Nazareth? They had to come up with a narrative that explained how he came from Nazareth, in Galilee, a little one-horse town that no one had ever heard of, but was born in Bethlehem, the home of King David, royal ancestor of the Messiah.”
