You either follow the Synoptic Tradition, or John (14:27, 16:33), it cannot be both.
Think not that I am come to send peace on earth: I came not to send peace, but a sword.
-- Matthew 10:34 (οὐκ ἦλθον βαλεῖν εἰρήνην ἀλλὰ μάχαιραν)
Suppose ye that I am come to give peace on earth? I tell you, Nay; but rather division:
-- Luke 12:51
