There are so many arguments back and forth between the Mormons and Christians as to really what it comes down to is what is true Christianity and who can be classed as Christians. The anti-Mormons will argue that just because the Mormons believe in Jesus does not make them a Christian because even the demons believe in Jesus. The argument will retort right back by the Mormons again that the believe what Christianity is among Christians is that it again does not refer to the same type of Christianity that took place in the New Testament.
