Christy: Thanks for giving such a thoughtful response.  As to your first thought about the way language about the divine as mediated by the person of Jesus, I hear you.  In my experience (for whatever it's worth), most of the people I talk to who've walked away or decided against Christianity give as their reason something like "hypocrisy," or "dead ritual," or that it's "intellectually compromised," etc.  I didn't mean to suggest, however, only that Christianity is perfectly acceptable theoretically; it's Christians who screw it up by failing to put it into practice--because it's possible to have real problems with Christianity in theory, before one ever gets to the embodiment.

In regard to your second point about the connection between using religious terms and belonging to a religion, I agree with your conclusion that doing the former doesn't imply a need to do the latter.  My argument is with the idea (held by many of my university students, for instance) that spirituality can be created, if not "ex nihilo," then certainly unaided by anything or anyone other than individual creativity.
