For a mere legend about Christ, in the form of the Gospel, to have gained the circulation and to have had the impact it had, without one shred of basis in fact, is incredible. Such a story is so wild it would never get off the ground because there are still too many people around who knew Kennedy. The legend theory does not hold water in the light of the early date of the Gospel manuscripts. The only other alternative is that Jesus spoke the truth. From one point of view, however, claims don't mean much.
Talk is cheap.
Anyone can make claims. There have been others who have claimed to be God. In my case it wouldn't take you five minutes to disprove my claim. It probably wouldn't take too much more to dispose of yours. But when it comes to Jesus of Nazareth, it's not so simple.
