Stephen Prothero wrote this really interesting book, God Is Not One, where he argues what seems in retrospect to be an obvious point—that Hindus, Muslims, Christians and Buddhists don’t share the same beliefs and by extension don’t worship the same god(s). The question, I guess, is whether each worships a different god, or the same one seen through a specific social/cultural filter. His argument about what each religion sees as “the problem” is really pithy and fun. As a Unitarian Universalist, I’m not ready to throw in the towel, but I’ve enjoyed the perspective a lot.
