That we are inherently evil people that need someone to give us all the instruction, tell us what to think and do, and control our ideas. Of course, there is one person that is capable of saving us IF we are willing to follow a few rules and sacrifice time, money, and energy to some religious leader.
This is common to all Christian denominations. True, some are more ridiculous than others (the Watchtower Society is extreme, and they substitute the Filthful and Disgraceful Slavebugger for Christ, and they focus too much on the rules and the sacrifice). But all of them distort Christ's real intended message--which is freedom of thinking on one's own. Notice that the truth was supposed to set one free, not bind one to a bunch of mandatory traditions, celebrations, observations, and/or sacrifice. Nor was a small group of people supposed to get rich off the backs of those in the membership.
I don't think it's possible for anyone to be a true Christian--that is, anyone other than Christ himself. Christ himself would have felt defeated if his followers tried to imitate him in every little way, since he was trying to get them to think on their own rather than do their thinking for them.
