I do not expect that the mere fact that I was once an evangelical apologist and now see things differently should itself count as evidence that I must be right. That would be the genetic fallacy. It would be just as erroneous to think that John Rankin must be right in having embraced evangelical Christianity since he had once been an agnostic Unitarian and repudiated it for the Christian faith.

Speculation is not knowledge.

Does it take a blanket presupposition for a historian to discount some miracle stories as legendary? No, because, as even Bultmann recognized, there is no problem accepting reports even of extraordinary things that we can still verify as occurring today, like faith healings and exorcisms. However you may wish to account for them, you can go to certain meetings and see scenes somewhat resembling those in the gospels. So it is by no means a matter of rejecting all miracle stories on principle. Biblical critics are not like the Committee for Scientific Investigation of Claims of the Paranormal.

In broad outline and in detail, the life of Jesus as portrayed in the gospels corresponds to the worldwide Mythic Hero Archetype in which a divine hero's birth is supernaturally predicted and conceived, the infant hero escapes attempts to kill him, demonstrates his precocious wisdom already as a child, receives a divine commission, defeats demons, wins acclaim, is hailed as king, then betrayed, losing popular favor, executed, often on a hilltop, and is vindicated and taken up to heaven.

If, when we compare two versions of a story, the second known to be a retelling of the first, and find that the second has more of a miraculous element, we may reasonably conclude we have legendary (or midrashic or whatever) embellishment. The tale has grown in the telling. This sort of comparison is common in extrabiblical research and no one holds that it cannot properly indicate legend formation there.

The notorious tendency of conservative apologists and New Age paperback writers alike is to leap from mere possibility to the right to believe. "If there might be space aliens, we can assume there are." "If the idea of Atlantis is not impossible, we can take it for granted." "If the traditional view of gospel authorship cannot be definitievely debunked, we can go right on assuming it's truth." No, you can't.

Today's Politically Correct "historical Jesuses" are no different, being mere clones of the scholars who design them.
