McLarenism--another gospel

I read Brian McLaren's A New Kind of Christian a few years ago. I did so tethered to a friend in order to not be deceived by someone's unique communication skills during one of my "questioning phases". For those who don't have such friends to tether to, try on Kevin DeYoung. He writes a great response to McLaren's new book, which he is bold enough to call a New Christianity. Christianity is about the gospel of Jesus. A new Christianity then, must be about a new gospel or a new Jesus or both. Seems to me that the apostle Paul had words about this kind of thing.
