Jo S,
The church in the city is biblical. That's why you can't let it go completely. The Bible never tells us to figure out how to implement it. It just presents it as something that is real. It just means God sees us as one. Not one organization, but one family. Whether we all meet together and recognize the same pastors is irrelevant. What is relevant is that we receive and honor one another, and are willing to cooperate to some extent.
Through that a lot can be accomplished. I'm already seeing it happen. It's got nothing to do with organizations. It's just Christians getting along and cooperating, putting the majors ahead of the minors. It's nothing to fear.
The forum is a good example. Well, sometimes.
