It's not my "personal beliefs" that Mormonism, Jehovah's Witnesses, and Christian Science are not Christian. It's inherent in their own self-proclaimed scriptures, and their statements about the nature of Christ, which differ (esp. in the case of JWs) from Jesus' own statements, which are the basis for my beliefs, not my personal tastes.
Christian Science appears to be dying out. Mormonism is growing rapidly. However, these 3 sects are still small compared to orthodox Christianity.
The idea that anyone can cook up his own "personal belief system" is known as cultural relativism, and is more commonly associated with the Left than with conservatism.
I disagree with you...you have made a personal judgement about which religions are and are not Christian religions...and yes, it is your personal judgement...you have made my point...
It does not matter if a religion is at a steady pace, growing or dwindling downward...that has nothing to do with whether they are Christian or not...
