I agree with you about the real question. (See my Post #17.)
Thus far, only a few posters have shown any interest in defining Christian. It seems to me that until that is done, we cannot possibly decide who is or is not a Christian.

This is not true in the process of defining something you may come across a property which can be used in an exclusionary way. In this case the Mormon penchant for polytheism (Where by they themselves can become a God) excludes them from Christianity. The Fact they limit Gods power by saying there are other Gods of other planets also excludes them..
points of Heresy are rather easy to spot when they are that bad..
