it isn't a matter of corrupting. It is a matter of fear.
For the average person, religion is a way of living and a way of dealing with death. Two big important things. For many people, the Bible is used to back itself up. As much as it sucks, circular logic is employed.
now, you must realize, in a situation like that, the shit hits the fan when something turns out to maybe be wrong. When something is not of the divine, but of man's hands.
Christianity pivots on it all being backed up by God. It does not pivot on it perhaps being a collection of man's wisdom and a poorly recorded record of the spirituality of a culture.
The possibility that they are wrong, and they are not right about death and life scares the shit out of most people. The beliefs of one's society and community changing and passing away, scares the shit out of people. And the power that will be lost when this culture shifts to that of a new identity scares the shit out of people.
Simple people in that situation do not give a shit about the truth or flattering God. They want their fear to go away and they want to KNOW that things will continue as they have.
