Just a brief comment on point 5.
One of my pet peeves was that a written agenda for all elder's meetings would be furnished several days before the event. Each elder could study the proposed topics, do research, pray, etc.
Inevitably, in spite of my broken-record insistance on a pre-meeting agenda, the PO would say toward the close of a meeting: "Bro. So-and-So has something he would like to bring before the body." Then Bro. So-and-So would detail a well-orchestrated plan for something, usually the weightiest and most far-reaching topic of the entire meeting. His chronies would add their support and influence. All the t's were crossed and i's dotted for this proposal.
My response would always be: "Well, its obvious some thought has been given to this, but the rest of us are caught a little flat-footed here. Perhaps, we could all give this prayerful consideration and consider it at the next meeting."
If looks could kill, I would have been dead 1000 times.
