Sam Harris vs. Rick Warren.
Follow up: I hadn’t read it all when I posted, but my assessment after finishing is that it’s pretty good and easy to follow. I’m biased, of course, but it’s abundantly clear to me that Warren can’t adequately respond to any of Harris’ objections. It’s all the same gobbledygook I used to hear back in Sunday school. That the arguments haven’t improved any, at all, suggests two possibilities: first, it’s just the best they’ve got (they really think Pascal’s Wager is clever); second, it’s sufficient to convince enough people, and in the end, it’s just a numbers game. If you could come up with arguments that would get people to believe in Zeus, then you would have "serious" theology surrounding Zeus (kind of the anthropomorphic principle applied to religious belief).
