No definitions available. Sorry. But for those wanting to discuss and think through the conversation, you can head over to Andrew's Blog (do I even read any other blog?) as he has just updated his "On Defining Emerging Church" post. I've read a few of them and it's a good place to just dig in (but please don't get lost in - at some point we actually have to be who we are) to the conversation.
