Today Pope Francis suggested that Donald Trump was "not Christian," citing the Republican presidential candidate's desire to deport Mexicans and build a wall. The New York Times reports that when asked about Donald Trump by a reporter on a flight from Mexico to Rome, Pope Francis responded, "A person who thinks only about building walls, wherever they may be, and not building bridges, is not Christian." Donald Trump responded to the Pope's comments on his website, writing, "If and when the Vatican is attacked by ISIS, which as everyone knows is ISIS’s ultimate trophy, I can promise you that the Pope would have only wished and prayed that Donald Trump would have been President because this would not have happened. ISIS would have been eradicated unlike what is happening now with our all talk, no action politicians." Click on for the funniest memes about the verbal tussle.
