mormonism is a “restorationist” church and thus should not (in my opinion) be classified as protestant, schismatic, or even apostate christianity. I do not consider it a christian religion either though. many new age sects and even Islam “recognize” jesus as being “important”. i see LDS as a heretical sect at best if one insists on categorizing a religion that does not worship or pray to jesus as “christian”. I think they are truly a new religion. they didn’t “transition” from another church (although a case could be made for sidney rigdon’s cambellite background). they started new with new concepts, doctrines and even scriptures. that they CLAIM a restoration of the original christian church is something the evidence appears to disprove. once again though there are other religions that recognize the bible as having some validity without being christian. so what are mormons? they are mormons. a unique religion just like their early leaders said they were. they have a lot of pentecostalish teachings as well some asiatic but wrapped up in a very nationalistic, “covenant race” type container in their early days and seem to have grown into a well marketed religious home based business type model like a spiritual amway. they teach the doctrines of men mingled scripture

and exercise hierarchical control over their members like JW’s. they have ongoing revelation with open canon but these days really downplay that so as not to appear all “branch davidian” (a good analogy to their JS days though). it’s kind of like a cheaper, easier scientology that appears sufficiently “christianish” to appeal to a larger demographic.
so to answer the OP… they are separate.
I agree. And I think that the most important reason I personally object to Mormons calling themselves Christian (when all know that it isn’t so) is that by calling themselves “Christian”, poor innocent people are “taken in” and not made aware that they are about to hear some “hard sell” about “a testament of a
different Jesus”. (Sorry BDawg, I really don’t want to offend you–you have been really very kind and open about answering–unlike some others–but both of us know it happens.) If those nice clean-cut and very polite boys came to the door admitting that their message is not a Christian message, but is a one from an organization that has beliefs that are quite contrary to it, the “investigators” would be put on guard and there would less likelihood of a Mormon baptism out of it all.
And of course without solid evidence of a total apostasy (loss of the priesthood) there is
no need for a “restoration of Christianity” which the Mormon Church says that they are.
(About the Total Apostasy claim–A hint to our Mormon friends: reread the Church history from the
beginning–from where Jesus gave His authority to Peter and follow it out
from there (using Catholic/Christian definitions instead of using LDS ones) to see if there
really is a break that may have resulted in a loss of the priesthood. With 2000 years of Church History, it’s easy to get sidetracked if a person tries to look for it from modern-day perspectives.)
As to whether Mormons are indeed Protestant, I think the question is answered when we consider the very word, protesting, and the date of the Protestant Reformation. Before that, there is
one Church, no Mormons, and afterward there were again no Mormons. In fact Mormonism didn’t come into being until 1830–a long time from the foundation of Protestant denominations. What Protestant religion did the Mormons split from? What Protestant religion claims the split. None? Well there’s the answer. Mormons are their own peculiar selves, not Protestant.
