But the one thing that ALL Christians believe that NEITHER Muslims nor Jehovah Witnesses believe is that Jesus is the Only Begotten Son of God and, is, in Fact, God. That is not a minor difference. Muslims are not a "branch" of Christianity - they do not hold to the creeds that ALL Christians profess. The waters of the Christian faith are not as muddy as you make it. Sure there are differences on theological issues and interpretations BUT NOT ON THE PERSON OF CHRIST. Christians DO agree on who Jesus is. That is what defines them.
