NewsElections Donald Trump vs. Pope Francis: An explainer By Jamie Reysen Updated February 19, 2016 10:33 AM Print Share fbShare Tweet Email Shade thrown? Pope Francis is the latest high-profile name to draw the ire of Donald Trump after the pontiff appeared to suggest that the Republican presidential candidate is not Christian. It all started when Trump last week took issue with the pope's trip to the Mexican border, calling the pontiff "a very political person." Then, the pope responded. "A person who thinks only about building walls, wherever they may be, and not building bridges, is not Christian," Pope Francis said Thursday when asked about Trump's plan to stop illegal immigration. The GOP presidential candidate quickly fired back, calling it "disgraceful" to question a person's faith. On Friday, the Vatican responded that the pope's remarks were not "a personal attack" on Trump. Take a look back at what Trump and the pope have said about each other.

Back on Dec. 25, 2013, he tweeted, "The new Pope is a humble man, very much like me, which probably explains why I like him so much!" But then he took issue with the pope's border visit Photo Credit: AFP / Getty Images / Jim Watson Donald Trump first criticized Pope Francis on Feb. 11 in a Fox Business Network interview after learning of the pontiff's planned trip to visit migrants at the Mexican border. "I think that the pope is a very political person... I don't think he understands the danger of the open border that we have with Mexico. I think Mexico got him to do it because Mexico wants to keep the border just the way it is because they're making a fortune, and we're losing," he told Stuart Varney. And the Vatican released a statement... Photo Credit: AFP / Getty Images / Tiziana Fabi Vatican spokesman the Rev. Federico Lombardi said in a Feb. 16 statement that "the pope always talks about migration problems all around the world, of the duties we have to solve these problems in a humane manner, of hosting those who come from other countries in search of a life of dignity and peace."

"A person who thinks only about building walls, wherever they may be, and not building bridges, is not Christian," the pontiff said while traveling back to Rome after his trip to pray with migrants in Mexico. "This is not in the gospel." ... and Trump was not pleased Photo Credit: Getty Images / Spencer Platt It wasn't long before Trump fired back at the pope, calling it "disgraceful" to question his faith in a lengthy statement. "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," he said. "ISIS would have been eradicated unlike what is happening now with our all talk, no action politicians." Trump then charged the Mexican government with making "many disparaging remarks about [him] to the Pope, because they want to continue to rip off the United States, both on trade and at the border." He continued, "For a religious leader to question a person's faith is disgraceful. I am proud to be a Christian and as President I will not allow Christianity to be consistently attacked and weakened, unlike what is happening now, with our current President. No leader, especially a religious leader, should have the right to question another man's religion or faith. They are using the Pope as a pawn and they should be ashamed of themselves for doing so, especially when so many lives are involved and when illegal immigration is so rampant." Then the retweeting began... Shortly after releasing his long statement, Trump's Twitter account started to retweet photos of the walls surrounding the Vatican. One photo that he retweeted came from DailyWire.com editor-in-chief Ben Shapiro's account. The tweet reads, "Pope on Trump: 'A person who thinks only about building walls...is not Christian.' This is Vatican City." Vatican: Pope's remarks weren't 'personal attack' on Trump Photo Credit: AFP / Getty Images / Gabriel Bouys Vatican spokesman Father Federico Lombardi said on Friday that the pope's comments on Thursday weren't a personal attack on Trump and explained that Pope Francis was just affirming that the world should help migrants. "In no way was this a personal attack, nor an indication of how to vote," he said about the pope's response to a question about Trump.
