The people that take everything from the Bible literally would be shocked. Smart Christians like me who know that there are metaphors in the Bible wouldn't be.
and it would prove once and for all that Jesus was a troll. Once they find all of his questions on yahoo answers printed off onto a sheet of paper he carries around - "The holocaust never happened. My dad hates fags etc."
Only that the historical figure Christ existed. It would of course cast some doubt on the story that he has risen to the heavenly kingdom, though that probably will be reasoned away like so many other inconsistencies.
