That’s what I am wondering. I can’t find scriptures where church boards have equal power to the pastor when it comes to voting on things, much less any scripture where a deacon board has much power at all - period.
Nowhere in scripture do we find a man heading a church called a pastor. Nowhere.
When the singular word “shepherd” or “pastor” is used in the New Testament, it always and only refers to the Lord Jesus Christ, never any other man. I Peter 5:4 for example, John 10:11, “I am the good shepherd.” And more. Only once in all scripture do we find the phrase, “My pastor....” Psalm 23.
The only time the noun pastor/shepherd is used in the New Testament, it is not singular, but plural. Ephesians 4:11
However, the verb form of the Greek word “poimen” is used as the charge, function, or responsibility of the elders (plural) or overseers (plural). E.g. I Peter 5:1,2 and others.
