"We are told by the word of the Gospel that in this His fold there are two swords—a spiritual, namely, and a temporal. […] Both swords, the spiritual and the material, therefore, are in the power of the Church; the one, indeed, to be wielded for the Church, the other by the Church; the one by the hand of the priest, the other by the hand of kings and knights, but at the will and sufferance of the priest."Nonsense.
John 18:36 Jesus answered, "My kingdom is not of this world. If my kingdom were of this world, my servants would have been fighting, that I might not be delivered over to the Jews. But my kingdom is not from the world."
“Do not think that I came to bring peace on the earth; I did not come to bring peace, but a sword." - Matthew 10:34
