I wanted to be an elder all my life. I had an ambitious personality, and as I look back, I latched on to the first goal offered and encouraged.
I am aware that the bible speaks of leadership. To be sure, all groups that try to organize will either have leadership imposed on it, or, the natural leaders will step up. Sometimes, its both.
Frankly, it isn't that the bible has its own leadership system in the OT and NT. It has everything to do with the concept of the governing body.
There are elders mentioned in each congregation. What isn't stated is a central body that appoints elders as JW's practice. The bible specifically mentions Paul, the Apostles, Timothy, Titus, and some others I think that are not coming to mind at the moment.
The bible paints the 1st century congregations as loosely organized communities of worship. They were visited by Paul, who seemed hell bent on enforcing all sorts of ideas not found in the gospels... (another story.) Interestingly, Jesus never referred to the leadership of elders, wanting all to be brothers, not to be rabbi's, etc. (yet another story)
When it comes to the elder arrangement of Jehovah's Witnesses, the issue isn't the need to have "organization" or leadership. Any group dynamic, even if its the "Toy's R Us Tots for Obama" gang (I made that up, work with me) will have some kind of leadership..... And the bible refers to leadership, so thats not an issue as to its utility.
It's the fact that the elder's have morphed. As far as the Governing Body is concerned, it is a frustrating necessity, because as much time is spent at the Service Dept at Bethel straightening out the messes elders create as they do helping elders shepherd their flocks.
Yet, without the elders, the GB could not have grown as they have. So they are not being disingenuous when they make comments in the Proclaimers book that the growth is in large part to having the elder arrangement since 1972. They have had good ROI.
If Freddie Franz only could see what he helped create. Instead of one easy elder to control per congregation, now you have a bunch of elders, who have turned into a bunch of Agent Smith's, very hard to control.... That is the downside.....
Oh wait, I'm sorry, they'refor YOU! The history, the BS, the politics, it could all be excused if they helped their flocks. But being an elder is a personal goal, an accomplishment. For all the politics that goes on, many bodies of elders can circle the wagons like nobody's business. (ostensibly, this is why MTS was started, to break up these body of elders......)
AND ITS NOT ABOUT THE FLOCK. ITS NOT ABOUT YOU!
Even if you get the occasional liberal elder who wants to help people, eventually, if it goes against borgish teachings, this well intentioned elder will have to make a decision on whether to the true to what their conscience is telling them or be obedient to the borg. Often, if an elder has a lot invested in the borg, (hints and promises of CO-ship, Bethel, Gilead, Assembly parts, etc) then they might screw you. Or they might step down. Either way, your help won't last for long.
