There is a great video of a discussion between Brian McLaren and Scot McKnight here;
McLaren is always worth listening to even if (like McKnight) you find him to have gone too far down the path of heresy. His intelligence and humanity mingled with a deep faith have been for many of us the means by which faith might live on beyond the religious straight jackets that we have gratefully shed. He has been a pioneer into new and deeper understandings, and these people are always seen by the establishment as heretics. Just read the comments under the video clip.
