>>It seems there are thousands of stories of people being driven from their churches when the pastor adopts the Purpose Driven philosophy.<<
A thousand and one. It's the main reason we left ours, and several other families left right behind us. PDL is a poisonous heresy.
Why do you say that? Have you read it?
I have, and while it's certainly not deep, I found nothing "heretical" about it.
The problem is not PDL. The problem is that people are using PDL instead of the Scriptures. PDL should be a starting point for moving further into the Scriptures.
The fact that people aren't doing that is not Warren's fault. If it wasn't PDL and Warren, there would be something and someone else taking its place.
