Well, only the Christians would be screwed if they found the bones of Christ. The Jews have all the tombs of their prophets, and the Muslims, too. In fact, I'm sitting here wondering if there is another religion which has at it's core, the ascension of it's founder. Christianity has not one, but two, don't forget the Assumption of Mary. (she had to wait until she was dead.)
Of course, not all Christians believe that Mary was assumed into heaven. (Sister Elephantina would cry out) Rather like the Sunnis and the Shi'a, there is a disagreement as to who is disappeared.
It's a many layered myth including the
Violet Flame
