scratchme,
The benefit I see -- for those who need it -- is that a Church provides them with a community of like-minded people. I guess I make it sound banal, but we see any number of communities of people who have similar convictions, and in this instance the commonality lies with myths and the supernatural.
I suspect that arguing against the belief systems of other myth-followers enables one to have a sense of protecting one's local community and of identifying with it. Although arguing against conflicting belief systems is a tool exploited by religious leaders to construct a fence around their sheep (Trinity, etc.).
While conducting this Study, I have been struck by the range of ideas and explanations regarding "salvation", to the point where I asked myself: "Why do people listen to and heed the opinions of religious leaders/voices?" Paul had his opinion (after supposedly speaking with the spirit of an executed person) but why should his ideas be taken as absolute?
My background had been within Christianity and that is the limit of my personal experience. There is such a vast tapestry for enquiry, and looking at these has helped me shape my relationship with current events. I have no real knowledge of belief systems outside the Judaeo/Christian stream.
I see Christianity as an element of Judaism. The Christian Bible is comprised of Jewish writings, apart from probably Luke, Acts, Hebrews and 2 Peter -- I am open to thoughts on whether there are other non-Jewish writings in any of the Christian Bibles. What about the Didache, Shepherd of Hermas, Barnabas and Thomas - were they Jewish in origin? Likely not.
