I recently read a good book on the topic, I think his name was Brent Webb-Mitchell and the book was Christly Gestures. If you ever read it you should know that I loved his theory, but when he tries to put it a practice from his theory he shows an amazing lack of understanding of how the church REALLY works. That criticism notwithstanding, I give him an A+ for TRYING to figure out what his theory means in practice.
