John Calvin and Jan Hus united human and civil matters with metaphysical concepts. This group constituted the Anabaptists. The Anabaptists were extreme and very frank in their condemnation of the government powers and the connection between these organizations and the Catholic Church. The difference between the two is that Charles honored his promise when he might have seized Luther, and Luther was then under the protection of the Elector of Saxony. Luther, on the other hand, had taken a more conservative approach to the propagation of the reformist principles. He did not incorporate political sentiments in his reinforcements. Instead, he called for a bloodless reformation which was denounced by John Calvin. Luther had a powerful political patron who sheltered him from his enemies, and Hus put himself in the hands of people hostile to him.
