Yep... Exactly. The written bible published by the two roman churches and later islam and later protestantism...was never written by anyone alive at the time. It was essentially spreading through out the whole Roman empire by word of mouth. As the Judeo-Christians were illiterate. But the Romans sure found out how to exploit that... ITs called roman catholic (universal changeable) and orthodox(preserved or maintained). The Muslims and Protestants could be defined as skeptics or disruptive to those older theologies built on controlling every aspect of human life.

Religion is about controlling the masses and treat hem like mushrooms - keep them in the dark and feed them crap.

There is always the greed component but, it is mostly about power and control.
