It seems to me that some people have a very narrow view of who is and who is not a Christian. I will make one thing very clear to them, however, and that is that I am not one. As a result I usually don't get involved in dogmatic discussions like this one. I am however, quite happy to become involved in a discussion of what actually defines a Christian. Just to clarify a point here is a dictionary definition of a Christian.
Chris·tian (kr
s
ch

2. Relating to or derived from Jesus or Jesus's teachings.
3. Manifesting the qualities or spirit of Jesus; Christlike.

5. Showing a loving concern for others; humane.
n.1. One who professes belief in Jesus as Christ or follows the religion based on the life and teachings of Jesus.
2. One who lives according to the teachings of Jesus.
Now it seems to me that Mormons fit all of the above parameters. It also seems to me that every one of the 2000 plus Christian sects seems to think that it alone has the one and only true Christian faith. If every Christian thought the same way then there would be only one Christian church, not thousands. Excluding any Christian group because it does not fit within the narrow parameters of one's own beliefs is simply a form of religious bigotry. Such thinking, of course is not new. It is why many Christians took such great delight in murdering, hanging, and burning one another during the European wars of religion.
Some believers may not think Mormons are Christians due to a few of their rather unusual beliefs, but I see little difference between Mormons and Roman Catholics with their religious relics and bizarre cult of saints or between Mormons and most other Christian groups.
