As earlier stated, churches were set up for the one purpose of controlling the thinking and actions of their members. Control is a very human thing. Why, because our humanity is controlled by Lucifer. At no time in history has a "Christian" ever been in control of anything. Why, because "Christians" can’t control. It is against the nature of God to control. God is love. Love must give you the right to say "Yes" and the right to say "No".
Right in the beginning we see this. God was a Christian and could not control Adam and Eve to obey Him. He gave them their choice.
Adam and Eve then became Christians and refused to control Cain. Cain refused to become a Christian and he tried to control Abel. When he couldn’t, he killed him.
