The Vatican probably loathes their presence there and views them as an American fifth column inasmuch as Mormonism is strictly one of those entrepreneurial religions that spring up like weeds in the USA. From what I've read of it,admittedly not much, one can have serious doubts that they are even a Christian religion. I once had a client who was a Mormon, from the Ukraine no less, and he was decidedly odd. It takes all.kinds, I suppose, but I will have nothing to do with them.
