When I did the series of posts on redefining church I briefly explored the concept that the church has an intrinsic sub cultural weakness, and like many institutions this is a preference for evolution over revolution, yet I feel that the shifts we see in scripture are so dramatic that they are more like revolutionary change.

Pete Rollins has been exploring the concept Revelation as a rupture and you can check out some of his thoughts here which in many ways helps describe the type/scale of change and root of what I was getting at. However I find it quite hard to find which post to recommend on his site so would suggest as an alternative to check out the talk he gave at Greenbelt 2006.
