St. Clement
The first witness is St. Clement, a disciple of the Apostles, who, after Linus and Anacletus, succeeded St. Peter as the fourth in the list of popes. In his "Epistle to the Corinthians", written in 95 or 96, he bids them receive back the bishops whom a turbulent faction among them had expelled. "If any man", he says, "should be disobedient unto the words spoken by God through us, let them understand that they will entangle themselves in no slight transgression and danger" (Ep. 59). Moreover, he bids them "render obedience unto the things written by us through the Holy Spirit". The tone of authority which inspires the latter appears so clearly that Lightfoot did not hesitate to speak of it as "the first step towards papal domination" (Clement 1:70). Thus, at the very commencement of church history, before the last survivor of the Apostles had passed away, we find a Bishop of Rome, himself a disciple of St. Peter, intervening in the affairs of another Church and claiming to settle the matter by a decision spoken under the influence of the Holy Spirit. Such a fact admits of one explanation alone. It is that in the days when the Apostolic teaching was yet fresh in men's minds the universal Church recognized in the Bishop of Rome the office of supreme head.
Here we see, quite early, the necessity of submitting to the BISHOP of Rome.
If you truly believe the v2 leaders are Popes you have to submit to them.
