I like Brent Barnett's take on the Emrging Church syndrome. I am very hesitant about this phenamena. I agree with his view of deception. Read on at his site, Relevant Bible Teaching.
The emerging church is a contradiction and an ethereal entity. It is always unsure of itself, keeping up a continual “conversation” (one of their favorite words) but never coming to any real conclusions. This is something to really be wary of because the deceptions are more subtle in practice than it might at first seem.
