I disagree about the "Lord's Prayer" being weird. I can see how it would strike too "Christianist" a tone, but this is hardly surprising from someone like Warren. But, as a prayer, you can't get much more basic, and I think it nicely presaged the return to basics Obama paid homage to in his inaugural address.
Give us "our daily bread"; "forgive our trespasses, as we forgive those who trespass against us"...what's not to like?
Don't blame the messenger for the message.
