As much as I admire your tolerance, I truly do, I must simply state that the Holy Mother Church does not view the Church of Jesus Christ of Latter Day Saints as a fellow Christian religion. Holy Mother Church considers only those faiths which can state the Creed without alteration, and with all sincerity, as Christian. As the LDS Church cannot do so, they do not belong to the christian faith.
If you disagree with this, and please no offense intended, I would suggest doing a little research into what the LDS church actually believes. I have no issue with Mormon’s on a personal or moral level. My best friend growing up is and was a Mormon, his family was always open and warm despite the vast differences between our theological views. That said, their beliefs go directly against the central tenant of the Judao-Christian faith family, that God is the One and ONLY God.
So as far as the building of one of their very beautiful temples in Rome, while I believe in tolerance, I personally find it rather depressing to see the city that has served as the center of the Catholic world for over two millenia, is so secularized as to have room or enough interested people to justify the building of a LDS Temple there.
Pax et Bonum,
