The idea or to think or say or imply 1st of equals, 2nd of equals etc. is a figment of our imagination coupled with wishful thinking. These 'positions' are not bibilicalyl grounded and do not have apostolic origin.
WE made it up; probably to placate humility and preserve a sense of arrogance and superiority at the same time.
The church is undefineable in such terms as 1st or 2nd and so on.
The Church of God is one and is headed by Christ.
How do you know where 1st position is or 2nd position is?
Do we determine ourselves or is there an actual position that can be found in Christs Holy Church?
The Church is the body of Christ. And His body is before the beginning and beyond the end.
That is why the word "church" is used o describe the faith.
"church" is to say 'circle' or round which is eternity.
This word (church) is very important to understand because it is filled with christeology. (NOT theology).
Examine names like Keril, Kerilos, Keriya, Kerka, Kerkos, Kereestos, Karl, Karlos, Circa, Circle, Curl, Charilos ('K' sound spelling of the saxons), Christ, Charles ('Ch' sound of the Germanics), Church. etc etc
If you research these words as well as words that mean 'round' in your own language you will begin to see the vast endlessness, unattainable, absolute meaning of the modern word 'Church'. And thus why the only real position is held by Christ.
WE are all servants of the Word incarnate on earth. The Church is out of our reach. It is a gift to mankind that he can have a life in the church.
Just think round.
How do you find the beginning (or end) of a circle?
If you can than you can find the primal position of the church.
I hope this is not too convoluted.
