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

There's a pretty glaring flaw in that. It either assumes it's 100% false, or 100% true. What if some parts are true and other parts aren't?

It's basing off of the idea that if God exists and what Christianity teaches is true, is the most important thing in life. Otherwise if there is no God then Christianity isn't important at all.
