I personally think that religion has less to do with ideology or dogma than it does with a certain way of life, attitude, community, etc. There is much more to the religious lifestyle than "interpreting scripture", for e.g., going to church, temple, etc. on a weekly basis, fund-raising for charities, meditating, praying, etc. on a daily basis, understanding that, while we can comprehend most of the world around us, there is still that mystical element, having certain kinds of weddings, having certain kinds of funerals, etc., etc.

What I'm trying to say here is that there is lots of reasons one may "bother" to be religious at all, if one loosely interprets scripture (if, even, at all!)

P.S. I think dogma of any kind; religious, scientific, artistic, etc. is always a bad thing. Dogma to me, is the bane of philosophical insight.
