I just find it odd that you would call all denominations wrong. Was The apostolic faith allowed to pass from human memory?
I don't read a whole lot about Church organization save the few pastoral epistles, but the churches in Antioch, Rome, and Alexandria were all very early establishments and many of their early bishops were second generation apostles. Antioch even claims Peter was its first Bishop before he went on to Rome.
These schisms, with each one, goes farther and farther from the church that The King established while here.
Where ALL can be called by The Holy Spirit to be priests, not just men.
Where ONLY the Holy Spirit can ordain you, not a pieces of lambskin from a college, university or seminary.
Where the priesthood is not a career.
Where divorce can only be granted if there is adultery by one or both partners.
Where you cannot remarry unless your spouse dies.
Where Mammon is not part of the worship.
Where alms are given in secret.
Where sinners are loved, but not their sins.
Where the Two Great Commands, not the ten, not the 613, are the ONLY commands to be upheld.
Where the faithful are reminded that we do not wage war of the flesh but of the spirit.
Where we render unto the fallen world what is theirs.
Where we do not yoke the righteous with the unrighteous.
Where we do not sell Grace.
Where we harm not the innocent.
Where we keep the Two Great Commands.
Where we use all scripture for teaching and reproof, not just what we traditionally say is canon.
Where we place The King on the throne, not ourselves.
I see no denomination, at present that can do ALL of these. They do some, or only in part.
The church is in disarray and is in need of revival.
. I just know I have been impacted by my own church and can't agree that all megachurches have this one motive
