Can the Christian Prince Have the Authority to Enforce Right Doctrine?

In the Puritan era in New England, which was very little religious freedom, he points out that they were willing to accept nonconforming or non-Baptists into their churches. They wanted to have all Protestants who worship the same Jesus who believe the same basic doctrines to worship together. As long as they didn’t disrupt the Commonwealth, they didn't disrupt town life, etc,. So I think he would say that he'd say in theory, if you're talking about people who are actually teaching a heresy that the Christian prince has the authority to even execute them.
