On Wednesday, Pope Francis answered a question about the presidential candidacy of Donald J. Trump by saying that “a person who thinks only about building walls, wherever they may be, and not building bridges, is not Christian.”

Mr. Trump, a Republican candidate, responded on Thursday, saying that it was “disgraceful” for a religious leader to question a person's faith. He also released a note on Facebook conjuring up the specter of the Vatican City being attacked by the Islamic State group, and suggesting that the pontiff was being used as a political pawn (though he did not say who was using him).

We’re interested in hearing from our Catholic readers about whether the back-and-forth between the pope and Mr. Trump influences the way they think about the 2016 election. Let us know using the form below. A Times reporter may contact you to learn more.
