Calvin's Main Argument in the Servitas Controversy?

If you were to bring Calvin back and just sort of put him in conversation with Kuiper and Bovingk, it seems like they would have a lot that they agree on because they're starting from these similar foundations. But then Calvin was obviously very much for this established church order that ordered civil life. And he made a mistake by suggesting to the magistrate or the magistrate, it was the decision of the magistrate what to do with him.
