Religions and governments from the beginning of time have used the idea of a God to lord over the people. God gives them and them alone The authority to rule and if your not a slave to them you'll die and be sent to hell or not go to and kind of decent after life.
This is nothing new and the cult likes it. The cult of Jehovahs witnesses is much closer in the way they act to the old chatholic church then most would realize. They even wrote in a WT in the 1950's that if it wasn't for the laws of the land they would like nothing more then to kill apostates.
