I've just recently become aware of the Joseph Farah-Rick Warren situation as well as the Brian McLaren-Mark Driscoll online "debate," which is now very dated (you can get most of the text here). In any case, having read all of the article written by Farah and the short rebuttal by Warren, on the record I side with Farah. Being late to the McLaren-Driscoll situation, I don't know that I have all of the info but I've read the original post by McLaren, Driscoll's response, McLaren's response to that and then Driscoll's short, to the point question to McLaren. That's where I've stopped. If there is more, forgive me, I'm not aware.

Anyway, after reading this and doing a little more research on my man Driscoll (I've written here before how much I appreciated his book "Radical Reformission" and his thoughts on various topics), this info below from Wiki also hits right where I am at right now:

Brief association with Emerging Church movement:
Mark Driscoll describes his association with, and eventual distancing from the Emerging Church movement in his blog"In the mid-1990s I was part of what is now known as the Emerging Church and spent some time traveling the country to speak on the emerging church in the emerging culture on a team put together by Leadership Network called the Young Leader Network.But, I eventually had to distance myself from the Emergent stream of the network because friends like Brian McLaren and Doug Pagitt began pushing a theological agenda that greatly troubled me. Examples include referring to God as a chick, questioning God's sovereignty over and knowledge of the future, denial of the substitutionary atonement at the cross, a low view of Scripture, and denial of hell which is one hell of a mistake."

I like a lot of the questions the emerging network are asking and some of the paradigms they are changing, but their lack of foundational theology greatly troubles me for the exact reason Driscoll notes above.
