One way to redefine church is to be Kingdom minded instead of church minded. In other words, we need to understand that the Kingdom of God is much bigger than the church. The seven main "gatekeeper areas" in any community where "church organizations" are just one of the seven. I believe these seven jurisdictions of authority line up perfectly with the seven Spirits of the Lord mentioned in Isaiah 11:2.
The following chart will explain these seven spheres of authority:
