The three quotes I gave you show that the priests (or if you prefer, "elders") had abilities not given laity; that the church was thought of as distinct place not suitable for eating anything but the Eucharist, even if arcghitecturally or legally it was someone's private property; and that the roles during the Church service were distinct and separated laity from the president and the deacons, -- all in direct contradiction to the Protestant mythology.
"Elder" and "priest", or "president" are incidentally all translations of "presbyteros"; one uses a similar word with a Germanic root, the other the same Greek root, and the third is the corresponding Latin.
None of your quotes state what you are trying to make them say.
James say that the elders of the church should pray over one who is ill.
Since elders (pastors) are to be in constant prayer, what is so unusual about that? (Acts.6:4)
As for having house churches, that is what the scriptures say existed ( a point you seem hard to deal with)
There are house churches today that are able to handle both the Lord's supper and adult Baptism (in a pool or stream) without any great difficulty.

Well, 'priest' has a far different modern connotation then does elder or even presbyterian.
As for 'priests' I read in 1Pe.2:5 that every believer is a priest, able to approach God directly, without any need for the intercession of a clergy class.
The only mythology that is going on is the myth of the RCC, that chooses its manmade traditions over the revealed truth of God (Mk.7:7)
