There have been some discussions I have come across here in the community of Missouri of what is the Catholic view on Mormonism. I personally adhere that the LDS Church is misguided in many areas and is not in line with orthodox Christian beliefs. The Resurrection is a major issue as outlined in 1 Cor 15:14-16. With that to the side, I have had a hard time coming across a official Vatican response to the issue. This is close as I could come for now. This is only part of the article that is relevent here. Seems to be in line with most Protestant viewpoints on how the LDS Church relates to Christ and other doctrines.
(Note: I have italicized and made bold the portion about The Church of Jesus Christ of Latter Day Saints(Mormons). Moreover, this article is not specifically about the Latter Day Saints, but does mention a view on the Vatican's official website about Mormon doctrine. Finally, the Dialogue Center(which this article seems to originate from) information is located at http://www.dc-international.org/)
although its current importance in American Evangelical Christian circles has come about through a concern with Mormonism. The Church of Jesus Christ of Latter Day Saints (Mormons) used to teach with some vehemence that Christians were doomed to hell. More recently, though, they have tried to insist that they, too, are Christians. Given their numbers, they claim that they are one of the “mainline” Christian denominations. But Mormon theology distorts Christian doctrine on most major issues; they have become rather reticent in their new stance towards Christianity about their teaching that “men (sic) can become gods”. In fact, though, they have maintained deification rites. This has sparked off a renewed interest in the writings of the Church Fathers on theosis (e.g. Saint Irenaeus’ dictum in the Preface to Book V of Adversus Haereses: “… Jesus Christ, who did, through His transcendent love, become what we are, that He might bring us to be even what He is Himself”). Confusion apparently reigns, especially since much of the discussion has been carried on through the Internet! But this article offers useful pointers towards a correct interpretation of the Christian doctrine of theosis.
