You keep making assertions like this, but you can't actually show these assertions in scripture. The requirements for these positions are listed, but the function is not, (at least not in the Bible).
Now that's a good reply!
Even though the Scriptures tell us that each local congregation is to be governed by a board of Elders with a second tier of Deacons, where 1 Timothy certainly speaks of the credentials of both an Elder and a Deacon but there is no mention as to who and what these people are.
As the silence of Scripture toward the makeup of a local Eldership allows in my opinion for a degree of diversity when it comes to the arrangement of the Elders, this does not mean that the Elders could not appoint someone to coordinate their meetings, such as with how the Synagogues of Jesus' time apparently appointed presidents for each Synagogue council, where the presidency was rotated between the Synagogue elders.
Paul tells us in 1 Cor 12:28 that the Father has established within each local congregation 8 Offices and theoretically, if these Offices are in proper operation, then we would expect these same Offices to be reflected within each local board of Elders, though I doubt that most congregations would have enough people to fully reflect these Offices within such a board.
1Cor 12:28
In the Church God has established . . .
1. apostle (aka, church-planter, missionaries who are directly involved with establishing new works.)
2. Prophet
3. Teacher
4. Deeds of powers (aka, miracles)
5. Healings
6. Guidance (aka, administrations)
7. Helps
8. Tongues
Even though our Evangelical brothers tend to dismiss the view that the Office of the
apostle is for today, they have oddly enough been sending out apostles for some centuries under the guise of church-planting missionaries; where after a period of time, where many of these apostle/missionaries have often been in sole charge of a local Body of Believers they have then moved on, which is what even the Apostles-of-Christ themselves always did.
As there are no longer any Apostles-of-Christ, which means that no ministy can justify trying to connect their ministry with Eph 2:20 "...foundation of the Apostels and prophets"; then any attempt to establish a system under this model where there is supposed to be an apostle over a particular region is absolutely untenable.
It should be pointed out that this thread is not so much about who is in leadership of each local congregation, but with the Latter-Rain/NARzie distinctive teaching that apostles are supposed to be in charge or various regions of the world.
