Are Mormons Christians?

[True Federalist (진정한 연방 주의자)]

It depends on which tenets of traditional Christianity one considers to be essential to be Christian.  For example, if one believes that Trinitarianism is essential, they aren't Christian.  If you consider believe in Christ as the savior of man to all that is essential, they are Christian.

That quote you gave isn't the part of the Nicene Creed that the Mormons would disagree with most.  As for the theological justification in the Bible that the Mormons have for the belief that the Christ visited North America, they point to John 10:16.  While the traditional Christian view of the verse is that the "other sheep" mentioned in that verse are the gentiles, the Mormons hold that Jesus is there referring to other groups of Jews that had been scattered elsewhere, such as those who had been sent to North America before the fall of Jerusalem to Babylon (according to the account in the Book of Mormon).  They also take literally the part of John 10:16 where Jesus says those other sheep will hear "my voice" so that the preaching is done in person, and not indirectly or metaphorically.

Heck, I don't buy Mormonism at all.  As far as I'm concerned the Book of Mormon is a hodgepodge written by Joseph Smith that contains an account of early North America that does not match up in the slightest with what is known today about what actually happened here pre-Columbus from archeology, ethnology, or linguistics.  But I don't think you'll find anything in the Book of Mormon that directly contradicts the New Testament, tho it does in places require a different interpretation than standard Christian theology.

Do Mormons (I don't know any) refer to themselves as Christians?

Yes they do.  Indeed, at one time they did not care to be called Mormons, but for the most part they have no problem with that now. (Some of the Latter Day Saint groups still do.)

I wonder how a Jehovah's Witnesses poll like this would go.

While their missionaries can be as irritating as the Mormons, except for other Christian groups who believe that they are the only true Christians (as the Witnesses do), I think most Christians would count them as Christians.

Unless they use the Trinitarian standard.

True, but unlike the Mormons, they don't have additional books of scripture besides the Bible.  I can see someone thinking they both are Christian, neither is Christian, or that JW is Christian but LDS is not.  I can't see anyone thinking Mormons are Christian while Witnesses are not, with the possible exception of any extreme Mormons who think that all non-Mormons are also non-Christian.

Actually, Ernest, we're literally besieged with radio commercials for the Mormon religion and those in the commercials constantly say "and I'm a Mormon".........

Yes, the Church of Jesus Christ of Latter-day Saints has embraced the term "Mormon" but some who hold the Book of Mormon to be scripture are not part of the church Brigham Young led out to Utah, while others have fractured off later. So just because the largest group of Mormons is fine with the term does not mean that all Mormons are.
