Pope Francis started out by saying (LINK), "A person who thinks only about building walls, wherever they may be, and not building bridges, is not Christian."
Asked specifically about Trump, Pope Francis said,
"I say only that ‘This man is not Christian if he has said things like that,’†Francis said. "We must see if he said things in that way and in this I give the benefit of the doubt."
...for ambiguity, for equivocation --- and even for insinuation --- but the record shows he did not initiate an attack on Trump. Despite being egged-on by the press, he chose to give Trump "the benefit of the doubt."
No, it was just a mealy mouthed attack instead of a direct one.
