I just listened to a great podcast of a lecture given by Diana Butler Bass. She is a church history PhD who, in this talk, is addressing a group of main line emergent folk. Though you may not be a "main liner", I think you'll find it helpful, especially if you lead in any context where you have persons of varying worldviews - ie. post-modern, modern or pre-modern - trying to coexist.
