Jehovah’s Witnesses and Mormons each have, uh, unique beliefs that don’t mesh very well with those of other faiths that call themselves “Christian.” I know I’m treading dangerous water here, but let me put it this way: I have attended Catholic, Baptist, Methodist, and Presbyterian churches so far in my life. I am involved with an interdenominational Christian organization on campus. Often members of one denomination disagree with the views, beliefs and interpretations of another denomination. In the case of the Catholic/Protestant spit the disagreements can be points of major doctrinal contention and the arguments can be quite heated. However, at the end of the day, all but the most bigoted individuals can agree that, while they may still feel that their opponents are in grave error, other denominations are still fundamentally Christian. I have never encountered anyone who felt that Jehovah’s Witnesses or Mormonism where Christian faiths other than those who practice them. My own (limited) examination of the doctrines of these faiths supports this observation.
If I have offended anyone, it is not my intent. I can only present things as I see them. Please feel free to PM me if you have evidence that can show me this assessment is erroneous, I will happily review it and change my opinion if that is the case.
