"Christianity, if false, is of no importance, and if true, of infinite importance. The only thing it cannot be is moderately important."

[radishhead]

Obviously untrue, and easily provable: look at the influence the religion has had throughout history, that shaped the world we live in today. Even if every word of the Bible was disproven tomorrow, it would still have been a belief system of massive importance (and therefore still would be, due to the effects on the structuring of society, laws, etc).
