“...RCC, the Russian Orthodox, the Geneva Reformed with Calvin, the Anglicans, the Lutherans.”
the difference is that “ the Russian Orthodox, the Geneva Reformed with Calvin, the Anglicans, the Lutherans” were actually owned and operated by the state to the point that in 3 out of 4 of them doctrine was decided on BY THE STATE. The Catholic was never owned or operated by the state, the state did not decide its doctrine.
You are right. Thr RCC ended up controlling the state, not the other way around.
Either way, they ended up persecuting independent believers.
