I think I have.If you want to attack their theology lay it out and explain it. But use specific theology. And give specific examples. Do not use the fact that EVERYONE believed at the time that the government and the church were comingled together. We all know that. No one is advocating that.
Puritan theology maintained the RCC doctrine that the government is a part of the church. Puritan doctrine taught that the Puritans were God's elect people charged with purifying the world (hence the name "Puritan").
Puritan doctrine taught that Baptists were heretics and the Puritans Church was charged by God with ending the heresy of "believers baptism" as it placed the souks of men in danger. It taught that Quakers held a greater heresy and they should be killed.
That was not their doctrine as a whole, but it was a part of their doctrine.
