Tipping my hat to Ed for pointing out Matthew's Table. This is similar to what Jane and I were thinking about oh-so-many eons ago. The idea seems to be catching on nicely now (and I don't mean to insinuate it was our idea in any way). I doubt ours would have ever been quite as classy or hip as this one. I like their liturgy: Blessing, Eating, Listening, Learning, and Sending.
