Mark Galli wrote a piece in Christianity Today musing about the future of the organic church movement. Although he's on the outside looking in (would have been better coming from someone who's actually participated in the movement), he does raise some interesting questions about the viability of the movement. I noticed in particular his thoughts on the current leaders of the various organic churches (whom cover a wide spectrum of 'church'), and echo his sentiments on the potential of losing many unhappy people in the future.
Organic church. The term is fluid, but it contains at least three ingredients: Frustration with the-church-as-we-know-it, a focus on people (vs. programs) and mission (vs. institutional maintenance), and a vision to transform the world.
