As for your comments on those who go into the ministry, I believe they go into it with the best of intentions, but once they actually start really delving into Scripture the obvious errors and contradictions found therein make them begin questioning the whole thing.
Most "Christians" are completely unfamiliar with their own Scriptures, relying instead on others to interpret them; most don't even read the Bible, but simply half remember Bible stories from Sunday school. However, when scholars subject "holy writ" to the same analysis to which they subject other ancient writings, those same Biblically-illiterate Christians are the first to cry "foul."
Self-referencial; can't use it.
