I think that’s the inherent problem with the doctrine of the papacy as proclaimed by the Roman Catholic Church. By virtue of his office and the dogmas associated with it, the Pope does not require the consent and agreement of the Church to proclaim dogma. Once the bishops themselves have agreed to accept whatever the present Pope may happen to teach, their very ability to function as teachers and defenders of the faith within Christendom is now compromised. They are now, instead of being overseers within the diocese they shepherd, reduced to being a voice of what the Roman diocese may happen to teach.
I’ve heard it said that Vatican I reduced the rest of the bishops to bishop making machines, as there was really now only one bishop. And as much as the supporters of the Vatican protest it, that is an accurate description: I’ve seen it proclaimed from the pulpit that the seminaries teach “the pope is 51% of the Church’s infallibility”).
This is expressly against the witness of Scripture, and the practice of the ancient Church. When Christ commissioned the apostolic ministry, he said “As My Father hath sent Me, even so send I you.” He says that He sends them individually in the same manner as He Himself was sent; hence He grants to no one a prerogative or lordship above the rest.
And St. I Clement reiterates what the Lord said (XLII-XLIV):
The apostles have preached the Gospel to us from the command of the Lord Jesus Christ; Jesus Christ [has done so] from the command of God. Christ therefore was sent forth by God, and the apostles by Christ. Both these appointments, then, were made in an orderly way, according to the will of God. Having therefore received their orders, and being fully assured by the resurrection of our Lord Jesus Christ, and in the word of God, with full assurance of the Holy Ghost, they went forth proclaiming that the kingdom of God was at hand. And thus preaching through countries and cities,
they appointed the first-fruits [of their labours], having first proved them by the Spirit, to be bishops and deacons of those who should afterwards believe. Nor was this any new thing, since indeed many ages before it was written concerning bishops and deacons. For thus saith the Scripture in a certain place, “I will appoint their bishops in righteousness, and their deacons in faith.” [Isaiah 60:17, LXX].
And what wonder is it if those in Christ who were entrusted with such a duty by God, appointed those [ministers] before mentioned, when the blessed Moses also, “a faithful servant in all his house,” [Num. xii. 7; Heb. iii. 5]. noted down in the sacred books all the injunctions which were given him, and when the other prophets also followed him, bearing witness with one consent to the ordinances which he had appointed? For, when rivalry arose concerning the priesthood, and the tribes were contending among themselves as to which of them should be adorned with that glorious title, he commanded the twelve princes of the tribes to bring him their rods, every tribe being written according to its name. And he took them and bound them [together], and sealed them with the rings of the princes of the tribes, and laid them up in the tabernacle of witness on the table of God. And having shut the doors of the tabernacle, he sealed the keys, as he had done the rods, and said to them, Men and brethren, the tribe whose rod shall blossom has God chosen to fulfil the office of the priesthood, and to minister unto Him. And when the morning was come, he assembled all Israel, six hundred thousand men, and showed the seals to the princes of the tribes, and opened the tabernacle of witness, and brought forth the rods. And the rod of Aaron was found not only to have blossomed, but to bear fruit upon it. [See Num. xvii]. What think ye, beloved? Did not Moses know beforehand that this would happen? Undoubtedly he knew; but he acted thus, that there might be no sedition in Israel, and that the name of the true and only God might be glorified; to whom be glory for ever and ever. Amen.
Our apostles also knew, through our Lord Jesus Christ, and there would be strife on account of the title of bishop. For this reason, therefore, inasmuch as they had obtained a perfect fore-knowledge of this, **they appointed those [ministers] already mentioned, and afterwards gave instructions, that when these should fall asleep, other approved men should succeed them in their ministry. We are of opinion, therefore, that those appointed by them,
. or afterwards by other eminent men, with the consent of the whole Church, and who have blamelessly served the flock of Christ in a humble, peaceable, and disinterested spirit, and have for a long time possessed the good opinion of all, cannot be justly dismissed from the ministry. For our sin will not be small, if we eject from the episcopate those who have blamelessly and holily fulfilled its duties/presented the offerings. Blessed are those presbyters/elders/priests who, having finished their course before now, have obtained a fruitful and perfect departure [from this world]; for they have no fear lest any one deprive them of the place now appointed them.
The episcopacy is an ontological whole, because there is but One Priesthood, that of Christ (as the Divine Liturgy says “Thou are who offers and is offered”). The ordained priesthood subsists in His Priesthood (which is why we don’t get into the issue of orders of those outside those bishops outside the diptychs, much to the Vatican’s frustration. Since we don’t commune with anyone not on the diptychs, it is not our concern: we are only concerned with the exercise of the charism within the Church, as it is not a possession or right that a bishop has outside the context of the Church. That is why, as St. Ignatius writes, “Where the bishop is, there is the Catholic Church” Smyrneans 8): the priests exercise it as an extension of the bishops (we do not hold to “a priest forever,” once you are defrocked (even when, as a case I know, not for wrong doing but volunatry resignation) you are no longer a priest; the deacons do so at the bishops pleasure (notice, it is an office the Church creates in Acts, not one directly from the Lord, in contrast to the Apostolate/Epispocy as shown at the beginning of Acts, complete with proof from the prophecies from the OT). So too the royal priesthood of the Faithful/laity. This is the basis of the Ecumenical Councils, which, just like Acts 15 do what "seemed good to the Holy Spirit and to us Apostles, the elders * and the brethren [the Faithful]"Acts 15:23, 28. Btw, this is also the basis of the so called Caesaropapism we are accused of (though I note that they don’t mind the meddling of King Ricardo of Spain and Henry II of Germany in sticking the filioque in the Creed): the emperor has the same responsibility to defend the faith in his station. (btw, Caesaropapism only exists in the West, the Anglican and Swedish churches being the chief examples).***
