Interesting. Why do you suppose so many churches are following him then? Mine did and I really didn't see the harm in it. Exactly what is the crux of his misgivings related to Christianinty? I've read a lot of conjecture here but no one is making a really good point. Just a lot of nit-picking at various interpretations of what he said, or meant.
Clarity is important. One thing that helps is that he has lots of printed materials available to document what he says and preaches. In a review of this material you can see unbiblical or scripturally skewed preaching.
Certainly not all of it but enough that causes myself to question his overall method of preaching and what his intentions are as a Pastor.
May I invite you to read THIS carefully and then answer your own question.
No hostility is intended. I am merely trying to open your eyes to another perspective.
There are so many reasons, but you really need to do some research. Do a Google search on Rick Warren, or Purpose Driven, and see what the opposition has amassed in information.
Many of us have studied this for years. Here's a good start for you: http://www.newswithviews.com/PaulProctor/proctor85.htm
read any number of his columns.
Do you realize that more people are LEAVING these churches than are joining? The largest growth movement is home churches and small churches, from people being "purpose driven" from the megachurches.
there are a few people on this thread who think Billy Graham preaches a false Gospel, so one whould not be surprised at the attacks on Rick Warren. He's not exactly a professor at a high brow seminary, so why should anyone expect him not to preach the gospel in a manner that is effective with the vast majority of the people who hear it.
