It's amazing as I read more and more sources on the Reformation how much Caesaro-Papism occured. It was really an Erastian Reformation. It wasn't theologians deliberating in Zurich or Geneva or Wittenburg, it was state-appointed theologians like Calvin and Zwingli who ruled with an iron fist (this might sound exaggerrated but I really don't think it is).
We had to read the other day about how Luther went back on the priesthood of all believers and the freedom of a Christian to a large extent as reformed-style Protestants arrived in Lutheran Wittenburg. The solution: disallow foreign students to enter the university without heavy fees.
We also read a document where Luther, Melancthon, and Carlstadt disagreed so viamently and referred to their speeches of 'angry bickering' that they had to sign this document saying they wouldn't discuss the differences anymore and try to forget it all.
Sola Scriptura sure was a can of worms. In a sense I think the Quakers and Anabaptists just took the principles of the Reformation to their logical end, and the Lutherans and more conservative reformers just fought to arbitrarily stop the reformation based on 'human traditions' that they had denounced (infant baptism, Trinitarian formulas w/ neo-platonic language, etc).
