Are Mormon's Christians?

[MODU]

This is the fault of labels.  Are Mormons "Christians?"  Are Catholics?  Are Mormons more "Christian" than Catholics?  Are Muslims "Christians?" 

In general, we consider the difference between Jews and "Christians" to be the placement of Jesus in the equation.  Similarly, we consider the difference between "Christians" and Muslims to be the placement of Mohammed.  With those being examples of where the various religions differ, you can consider the difference between "Christians" and Mormons to be Joseph Smith.  Smith is comparable to Mohammed in the way that he received visions/was a prophet which added onto the existing "Christian" beliefs.

So, using that concept, one could argue that no, Mormons are not "Christians."  They're just Mormons.

Mormons are like Muslims.  They follow an additional doctrine outside of the Bible, so they are not "Christians" in that sense.  They are their own stand-alone religion.  After all, the Mormon view of the afterlife is far different than "Christian" views.
