So the ancients commonly made up stories about how their gods were born through virgin births.
Yes, denying that is not an option, especially if your reasoning has any basis in history.
It’s the only logical way they could claim that a human being was also a god.
I don’t know any reason to assume that is a requirement.
To deny that the person was conceived by a god and born of a virgin is to deny the person’s divinity.
If that is the ONLY reason you have for believing Jesus was God, then I guess so. I see no logical way to insist on Jesus’ supernatural nature if you are
only relying on what was a common legendary way of writing about the infancies of great leaders.
So rejecting the virgin birth story of Alexander means you reject that Alexander was divine. And rejecting the virgin birth story of Jesus means you reject that Jesus was divine.
If you understood the classic literary form of the story, you would know that it is not a matter of believing or rejecting the story at all. The birth stories of Alexander, exactly like the birth stories of Jesus, were not written to tell us what happened from a historical viewpoint, they were written to tell us who the person was and to attach supernatural significance to what they became.
The author of an infancy narrative is not responding to the question “How can I tell the story of this person’s birth exactly as it occurred?” but to the question “How can I tell this story so that the reader understands just how great this person became?” An infancy narrative is
not written from a point of view contemporary with its subject’s birth; it is written in
hindsight, in the light of subsequent events to teach what came to be known about the person over time. The birth narratives of Jesus were written after the resurrection, after the disciples had come to understand Jesus’ true identity (exactly like the other infancy stories we have discussed).
If you understood the point of view of the author of an infancy narrative, you wouldn’t ask, “Are infancy narratives historically accurate?” The author is not trying to describe events exactly as they occurred, as would a historian. Rather, the author is trying to describe events so that the listeners, or readers, understand the significance of events within the context of their lives.
Scripture scholars believe that Matthew and Luke’s infancy narratives include a historical core – the information that the stories have in common – but they also contain many details that do not find their source in events but in the text of the scripture. The infancy narratives wind throughout their accounts of events scriptural images that cast light on the significance of events. (This teaching technique, known as midrash, was common in Jesus’ time and culture).
