GfS,
Are you talking about experiencing the oneness of the universe, and being aware of the power that animates it? Or are you talking about worshiping a conscious being that chooses to be involved in our lives, had a human son with a virgin mother, and generally conforms to the mythologies of various religions? My question is how anyone gets from the first to the second.

I consider myself a deeply spiritual person, and that means that I have had deeply spiritual experiences. It is a capacity that humans have, and it has been documented extensively in most cultures and can be taught to most people. But the most important thing is that it is a deeply moving, often life-changing experience that brings the perception of greater awareness, of being plugged in to the whole cosmos in some way. If that is how you are defining belief in god, then we are in agreement and just need to work out the terminology.

But if you want to say that it is rational to believe in three-in-one, Satan, rose from the dead, god wrote the Bible (or said anything at all), then we have source of serious disagreement.
