The organization of church government was shown clearly in Acts 20 and 1 Timothy.
These were the guys Timothy had picked according to the instruction of Paul. The Greek word interpreted 'bishop' is, also, translated 'overseer'.
Thus, we know that a city's church has a plurality of bishops.
The bishops were not, as individuals, autonomous, the bishop council was once they had been commended to God and the Word of God's grace.
Thus, they were supposed to watch each other. Specifically, they were supposed to make sure that none of their number started taking advantage of the sheep by becoming manually unproductive.
It takes only three years to prepare men to become bishops. Since they are productive in order to gain the giver's blessing, the have resources which must be distributed to the weak. That job is given to a person who is drafted by the congregation and overseen by overseers/bishops. The draftee becomes a deacon who, if proven to be faithful in small things, gets promoted.
When deacons are proven, they may be promoted into offices of deacons. The Greek word transliterated 'deacon' is, also, interpreted 'minister. A deaconry is a ministry.
It is natural that elders/bishops/overseers could be drafted for the deaconry. But, Peter says that they should not wait to be drafted.
So, you would like a nice communal church, which is episcopal, having independent Bishops overseeing Priests (ministers) and deacons?
