Great opening post!! My response addresses the opening post and does not address any of the follow-on posts.
Clarity is a key for constitutional changes. You could make a change for one purpose, and because of vagueness, the change could then be used for a different purpose.
1) To whom does the Elder or Elders report to? Must they report to the membership quarterly? Are they accountable to the membership. Can the membership remove them from office by a simple majority vote. Otherwise leadership can usurp power unto itself.
2) Are Elders nominated by the Deacon/Elder board and then confirmed initially and periodically (every 3 years) by the membership.
3) Which decisions must be approved by the membership, such as real estate transactions?
4) Disqualifying behavior, prior to professing salvation should not be held against believers after a period of years (3?) subsequent to professing salvation, but disqualifying behavior subsequent to professing salvation should apply for at least 3 years, and at the discretion of the membership, could be considered a permanent disqualification.
5) Your qualification requirements for your church can be established by your membership. Since smoking and drinking set an example that could cause some to stumble, the Bible allows for requiring your leadership to abstain from substance dependence.
Hopefully you will not include soda and coffee in your list.
1) Currently the leadership reports to the congregation monthly on matters of church operation such as the members whom we haven't seen in some time, those whose membership is up for termination due to...unfortunately it seems that the only reason we see is that some husband has decided he no longer wants to be a husband and a father. That just occurred to me. The monthly church members' meeting covers those things. Quarterly or more often, as necessary, that meeting will discuss the church's finances as well as the finances of the K-12 school.
2) Currently, a nomination from a currently serving pastor or deacon, ratified by a simple majority (out of a church body of about 750-780: we are a church in a military town and we have a lot of turnover) is how we select deacons. We would select elders in a similar fashion, except they would be nominated by other elders, and demonstrate the ability to teach the Word, as that is the fundamental difference between the two offices. The unpaid will always outnumber the paid in the concept given by our Senior Pastor.
3) Which issues MUST go to the membership? To be determined. Right now, below a certain dollar threshold, and assuming the church won't incur more debt, the pastors and the deacons vote. That part will, under the new constitution become the domain of the elders, both paid and unpaid. Determining the actual dollar amount seems a bit tricky off the top of my head because say $1000 (pulled that number out of air) in 2018 will not be the same as the same amount in 2028, 2038, etc....
Constitutional and other changes to how the church stands on a biblical issue resemble a representative democracy: now the pastors and deacons, but hopeful in the future, elders will draft, refine and assuming a majority of elders then wish to proceed, present them to the membership for a 2/3 vote. Our most recent example was just last year to more clearly articulate our stance on gender. We believe in two. God made them and called them "man" and "woman", equal in value, distinct in purpose.
4) Disqualifying behavior - This is where the potential for the inner workings of the committee to become contentious. Currently, "...the husband of one wife...." applies completely and prescriptively, that is, we have no single men in any leadership position. We also have no divorced men in any leadership position. It's the first question they asked me when I was nominated as deacon. It's serious business, and it should and shall remain so. However, in many of the cases, the divorce occurred well before salvation, even decades, and the man has subsequently been saved, married and faithful to God and his wife.
3 years, perhaps as many as 5, seems like a long enough time.
5) Alcohol and tobacco - Forbidden to everyone who holds any position in the church or in the school. The partial revision will not change this at all, but simply include the newly-created office of elder in the language of the restriction. That change MUST occur if the office of elder is established.
The full revision will prohibit public and excessive drinking and specifically prohibit drunkenness.
