I have been getting quite an education in Protestant Christianity from the WTM boards. I have to admit that I am much more familiar with most major world religions than I am with general Christianity. I am a Christian myself, but I really only know about my specific beliefs and practices.
I had no idea before that children in many churches don't sit with their parents during the main worship service. I didn't know that contemporary Christian music was so widely used instead of hymns. I didn't know a thing about Universal Unitarians. I had no idea that Jehovah's Witnesses don't belive that Jesus Christ is divine. I didn't know that people would change churches so often to find one that fit their style and that styles within a given denomiation could vary so much from place to place.
I can tell you about Jewish practices. I could tell you about specific divisions within Islam. I've read a lot about Eastern Christianity. I'm pretty good with Christianity historically. But I have a definite gap in what I know about contemporary Christianity, and I need to fix that.
Are there any good unbiased books out there that would help me with this?
