Whether in business or pleasure, Donald Trump deals only in so-called transactional relationships. If the pope has nothing material to offer him I doubt Trump's interested in much the pope has to say, except perhaps where his own "ratings" are concerned. If they're dipping a little low among Catholics he'll send out a 3 am tweet saying how much he loves the pope then all will be right with the world again and everybody's happy, including Catholics - or so it would seem.
