I think you can only judge people by your own reactions. If I started telling people that a concept named God somehow dictated a whole series of apparently contradictory texts at various times to various people so that as mis-copied and mis-translated they would, thousands of years later, be absolutely true I'd be a cynical lying scoundrel, or a brainwashed idiot, and anyone who trusted me would some sort of Dostoievskian Christian or a halfwit. How exactly are these persons different from me? Are they brighter? Do they have some special revalation? I think not. Why then should I trust them?
