Others would cynically suggest Cameron is just trying to make a buck with a sensational claim.
But such a claim is a resurrection in itself: A 1996 BBC documentary made similar claims about the same tomb. Then, as now, scholars scoff at the notion.
More importantly, Cameron and Toronto filmmaker Simcha Jacobovici are recklessly rooting around the cellars of the beliefs of 2 billion Christians around the world.
Can you imagine the outcry, the outrage, the protests, were filmmakers to question the foundations of, say, Islam?
You needn't imagine it. Consider the riots that ensued after the publication of mere cartoons about Muhammad in Denmark. Or the brutal slaying of Dutch filmmaker Theo Van Gogh after he made a movie about Islam's treatment of women.
So Christianity is a much safer target. And every Lenten season, we're treated to a fresh attempt to disprove the fundamentals of the faith, to ascribe some new human frailty to the Savior, to rewrite the Scriptures, to have archaeology triumph over faith.
Christians may not take to the streets to show their displeasure over this unfortunate rite of spring. But we're bone tired of these recurring attacks, this made-for-television junk science that some folks clearly hope will pull the rug out from under the story of our Lord's resurrection.
