How do you determine that there was no hierarchy in the first century Church from teh new Testament? Did not the Apostles make the decision to include Gentiles as full members despite their non adherence of Kosher? Not only did the Gentiles wait for their decision, they rejoiced, as if their authority mattered in what they were going to do. The very fact that Paul wrote to the Corinthians though he was not with the communion at the time and used his authority to discipline the church demonstrates hierarchy.
Montanism was the idea that the Church doesn't need ecclesiastical leaders but prophetic leaders (Montanus claimed he was the Holy Spirit). Your appeal to Clement and Polycarp is odd, since Polycarp affirmed the epistles of Ignatius who stresses Episcopal authority and Clement likewise chastises the Corinthian Church for doing away with their leaders in a fashion unbecoming of a Church. Clement insisted on an order for the Church which was found in the structure of leaders and laity and he assumes a communion between which it is possible for members of that one communion, despite geographical distance to criticise each other. The complete autonomy within Protestantism on the other hand, especially evangelical forms which insist on the absolute autonomy of the local Church to which none may challenge, hardly adheres to the structure of the first or second Century Church. There is a common communion within the early Church and thus an ability for members to correct one another.
The Ante-Nicenes were not Pentecostals, they were of the same Church that Augustine was part of. Now I agree we need to know what went askew, but on the whole I do not believe the fathers ever went askew, at least to the point where the Church required Protestantism.
In the early church there were the apostles, they were under Christ and God. Under them anyone could rise up with a great gifting, others with humbler gifts... There were names like Timothy and Apollos. But really there was God, the apostles and offices filled, laity serving, children rising, that's all, very flat hierarchy apart from God and Heaven.
Our hierachy consists of historical infallible writers, the Popes, the Cardinals, Bishops, Monsignors, priests, deacons and acolytes and laity. Also there are groups of Catholic Apologists that may not accept the popes letters as correct...
Montanus I have not read much about, but if they threw away personal prophecy with him claiming to be the Holy Spirit they threw away the baby with the bath water. It goes back to 1 Corinthians and the apostles teachings on spiritual gifts, offices, and the laying on of hands... even as in Hebrews.
A Bishop could be a prophetic leader, I recall a bishop is meant to be prophetic, and with that they would prophesy, say, in Corinth and test prophecy from gifted laity...
Corinthians were known to be jealous of others' gifting. I was bitten hard in my youth regarding this. Those bishops would have had trouble regarding the privilege of having a gifting and position above others. The old, "If you have a two story house, I must also have a two story house. If I can't afford it, I will help you rebuild after yours burns down."
Howard Storm is protestant and his church decides on who preaches there...
In my churches as a Pentecostal, they are run like business offices, managerial style. That is different. New fashion for a purpose, soul harvest.
It is important that in the fourth century for example that there were healing rallies.
Not all Pentecostals are the same, John Arnott of Catch the Fire decided not to become a CEO. And the messages are prophetic or for the laying on of hands. Many people are active, using gifts, able to make a point with the head pastor, or preacher. Global Awakening focuses on apostles and prophets, spiritual gifts, healing and freedom from sin,
people come at will, if they are critical, they can go to another church. This is a different demographic mission field.
Perhaps too much arguing and not enough soul harvesting was a mistake, too much dogma, extreme punishment and control. After St Francis approached the pope, but to not enough avail, and after Hus was killed then was a need for a break away even for the Catholic hierarchy to be meaningful. Not that Luther was 'all good'.
