If you haven't seen this video from Greg Hawkins, the Executive Pastor at Willow Creek, you owe it to yourself to watch it. It's a short version of Reveal, a book-form of qualitative research results on the effectiveness of the Willow Creek ministry philosophy and approach.
I won't rehash the video here. You can watch it for yourself or read what lots of other bloggers are saying, but the basic message from Willow Creek is 'Oops. We were wrong.'
A couple of thoughts I've not seen elsewhere:
1. It appears their strategy works as people move from non-followers to young followers. It breaks down the longer someone is a Christian. That's unquestionably not a good thing, but it's not as if their strategy had not value. It simply looks like it didn't have the capacity to reliably move people beyond early growth stages as followers.
2. My bet is most ministry leaders who followed Willow Creek in the Dao of the Big Box will look to Willow Creek to chart the new course. I don't get the sense that WC is losing credibility in this--mainly because most people trust that they will actually work to correct the HUGE problem.
3. I'm EXTREMELY interested to see whether other Big Box churches own up to the findings of Reveal or pretend that the findings aren't true for their church. What 'Reveal,' um, reveals is that the problem is systemic. It's not particular to Willow Creek. So if you're a Big Box ministry leader, you need a pretty good argument as to why your church is exempt from the problems their research uncovered.
