If there's one person a professed Christian doesn't wanted dissing them, it's the pope.
Too bad for GOP presidential candidate Donald Trump, because Pope Francis had some strong words for the frontrunner after his visit to Mexico this week.
Speaking with reporters Thursday as he was returning to Rome, the pope said anybody who wants to build a border wall "is not Christian," according to the Washington Post.
Not one to let anyone speak ill of him, Trump fired back by saying he is a proud Christian and calling the pope "disgraceful."
Trump added that as president, he would "not allow Christianity to be consistently attacked and weakened, unlike what is happening now with our current president."
