What did martin luther do in response to his disagreement? what was the initial reaction?

 Protestant sects as to how to deal with the Catholic Church, Luther encouraged his follows to refrain from violence, since he knew the movement was fragile and could break easily.

They made a checks and balance system to equal power within the branches. the "check" meant that one branch would watch one branch and "balance" them if they were too powerful. if you want more info on this, i would just google checks and balance system.
