For me, the only reason to abandon a human hierarchical system is for something directly from God. My wife and I were called out of the system to break bread from house to house in 1990. While the road has been long and perilous, the depth of encounter with the Lord is worth every difficulty. Experiencing a revival changes everything.
I haven't looked at the current stats, but it seems there is a move away from the institutional church. On the other hand,
I can see the value of the cooperative effort to build something that facilitates a comfortable environment to meet in.
I was involved for a short time helping out with a church plant extension of the church we were attending at that time.
Considered a campus of the parent church, the whole thing fit in a trailer that we drove to the elementary school where we rented space.
And I remembered having the feeling of the early church as we carried all our gear in to set up in the cafeteria.
After a Sunday of arriving early and setting up for a small congregation and staying late to pack everything back in the trailer,
it really makes one appreciate having your own building where everything is pretty well ready to go.
