I've been thinking about the emerging church stuff quite a bit and read Andrew Jones' blog where he writes:

Translate that to church: Our parents defined church by what they DID when they got together. But what if emerging church was defined by what people gave up to be together, by the activities that they sacrificed in order to "assemble" and the assembly itself was an act of worship, valuable because these people stopped the machinery of makingmoney/havingfun/cleaninghouse/etc to BE TOGETHER with God and each other. Not what you do, but what you don't do. The Catholics might do this better than the Protestants - with their discipline of silence, abstenance from foods and things, fastings, etc.

Its good fuel for thought.
