In response to Martin's question:
I'm just about three quarters through. We're reading it in staff meeting and have covenanted not to read faster than each other.
It is quite enjoyable. Brian Mclaren is having a Big Blogger conversation. However if the truth be told his conversation is between ultra-conservative evangelicalism and modern evangelicalism. It doesn't move much beyond that into post-modernism.
Interesting about other faiths, evangelism as conversation not conversion and interpreting the Bible through our own cultural grid.
Essentially I think the church is going to change dramatically in the next 25 years. In the meantime the best versions (franchises) of the old way of doing church will thrive. One story from the book is about transport:
If you were going to buy the best possible mode of transport in 1910 what would you buy? Many would say that the age of the car was just beginning and they would buy a car. They'd be wrong. As the age of the car was just beginning, cars were incredibly unreliable and dangerous - you sat behind plate glass. If you wanted reliability you'd buy a buggy. Buggy technology had reached a pinnacle and only the very best buggy manufacturers remained in business. Horses were reliable.
As churches die out all over the place they are like buggy manufacturers going out of business. Anyone wanting a church will go to a surviving one. The remaining ones will get bigger and better. Few will buy a car until they become knowingly useful and reliable.
I've seen the car coming and I don't think many others have. Meanwhile buggy manufacturing churches will fall away because of:
Buildings being in the wrong place
Treatment of women in leadership
Failing to attract younger members
Treatment of the gay and lesbian community
Better and bigger churches being more attractive
Insistence on newcomers eventually ticking boxes to do with minor bits of doctrine
Failure to ditch the 'Bible as history' model and embrace science
And then the car will come...
I'm sure the buggy preservation society exists and has an enthusiastic and active membership who get together, show off their polished buggies and talk about the old days.
