So you are saying that no religion has ever told their followers that they are "bad" so they could be controlled and manipulated?
How do you think cults get so much power over their members? It's because the followers believe that the religion has the "answer" to their salvation.
"Cults" are not Christianity. Anyone who follows the dictates of a human being (be they priest,pastor,imam) are subject to error. The Scripture which has proved itself merely by surviving efforts to stamp it out over 4,000 years should be our manuel for living.
As a matter of fact, there's that "moral relativity" so many complain about. "we're all sinners" equates shoplifting with mass murder.
I'm off to work soon so not many more responses today
