The Rabbit and the Elephant by Tony and Felicity Dale provides an intriguing perspective on "doing church":
Put two elephants in a room together, close the door and in 22 months you'll end up with one baby elephant. Put two rabbits in a room together, close the door, and in 22 months you'll end up with thousands of baby rabbits!
The Dale's, teamed with George Barna, make a case for Rabbit Churches (house churches -- or at least congregations that have that kind of mindset) as opposed to Elephant Churches (or the traditional approach.)
Although they overlook some major advantages to the classic church structure, they bring a refreshing new way of thinking about doing church in a way that is relevent and real.
One concept of the book was absolutely transformational for me -- thinking of church as liquid rather than solid.
Solid church is the structure -- the budget -- the program - -the building -- the policy.
Liquid church is the relationship -- the love -- the flowing with the Holy Spirit.
I have really thought a lot about this and would like to write, speak and blog much more on the concept in the days to come. (My belief is that church should be both solid and liquid -- with the emphasis on liquid!)
