Well, to be fair, the guy didn't say that he came to bring peace. He said that he came to bring a sword, drawing from Jeremiah 25:15 where the sword is identified as a curse in a cup of wine.And peace hasn’t come to the world.
Take from my hand this cup of fiery wine and make all the nations to whom I send you drink it. When they have drunk it they will vomit and go mad; such is the sword that I am sending among them."
