Admittedly this is off-topic now, but you raise an interesting point about the definition of being a christian (or any other religion). To what extent can you ignore some of the core teachings but still define yourself in that way? Is this how the different sects formed, with people rejecting some teachings in favour of new interpretations? Take islam: I saw a chart which showed something like 20 different sects, I couldn't name them all, but you have sunni, shia, and the one Assad belongs to (allawites?) and a lot more. As far as the different religions all being the same basically, their teachings are quite different, no? I don't think that works. (But I'm no expert, so correct me if I'm wrong).
