If any one attempted to rule the world by the Gospel, and put aside all secular law and the secular sword, on the plea that all are baptised and Christian, and that according to the Gospel, there is to be among them neither law nor sword, nor necessity for either, pray, what would happen? He would loose the bands and chains of the wild and savage beasts, and let them tear and mangle every one, and at the same time say they were quite tame and gentle creatures; but I would have the proof in my wounds.
