Brian's new kind of Christianity is quite old. And the problem is that it's not old enough.
McKnight does an outstanding job of reviewing Brian McLaren's 'A New Kind of Christianity' and explains why he thinks McLaren has drifted from both evangelicalism and orthodoxy and wandered wandered down the path of 19th Century theology.
Perhaps you have joined Brian McLaren in his wanderings, hoping that somehow this 'fresh perspective' will give birth to a 'missional church'. It won't. It can't. It never has been anything more than the symptom of a faith that has lost its way.
