A belief that could not possibly meet the Vincentian canon of
Universality, Antiquity and Consent, and in fact a belief not universally shared by Catholics even within living memory of the Council that solemnly defined it.

St. Cyprian:
“The heretics dare to sail off and carry letters from profane schismatics to the chair of Peter, to the first of Churches from which first came the unity of the priesthood. Don’t they know that they are Romans there, whose faith was praised by the preaching of the apostle, and among whom faithlessness can have no influence?” (Letter 59 to Pope Cornelius, 14, A.D. 252).
Bachiarius, monk, (fl. 420 AD):
“…none of the heresies could gain hold of or move the Chair of Peter, that is the See of faith.”
(Professio fidei, 2)
John Cassian, Monk (c. AD 430), to Pope Celestine I:
“That great man, the disciple of disciples, that master among masters, who wielding the government of the Roman Church possessed the principle authority in faith and in priesthood. Tell us, therefore, we beg of you, Peter, prince of Apostles, tell us how the Churches must believe in God.”
(Cassian, Contra Nestorium, III).
Socrates Scholasticus (c. AD 380-450), a Greek Church historian in Constantinople:
“…the churches shall not make any ordinances against the opinion of the bishop of Rome.”
(The Ecclesiastical History 2, 8)
St. Peter Chrysologus (449 A.D.):
“We exhort you in every respect, honorable brother, to heed obediently what has been written by the most blessed pope in the city of Rome, for blessed Peter, who lives and presides in his own see, provides the true faith to those who seek it. For we … cannot try cases on the faith without the consent of the bishop of Rome.”
(St. Peter Chrysologus, Letters 25:2)
Theodoret of Cyrus:
“For that holy see has precedence of all churches in the world, for many reasons; and above all for this, that it is free from all taint of heresy, and that no bishop of false opinions has ever sat upon its throne, but it has kept the grace of the apostles undefiled.”
(Theodoret, Ep. 116, to Renatus the presbyter. A.D. 449.
The Greek historian Salminius Hermias Sozomen (A.D. ca. 375?-447/48):
“For there is a priestly law, making void whatever is effected against the mind of the bishop of Rome.”
(Sozomen, Church History, Book 3. A.D. 450.)
St. Fulgentius of Ruspe (A.D. 465-533):
“That which the Roman Church, which has the loftiest place on the earth, teaches and holds, so does the whole Christian world believe without hesitation for their justification, and does not delay to confess for their salvation”
(Letter 17, 21, A.D. 519).
Signatories of the “Formula of Hormisdas” (519 AD) to restore union after the Acacian Schism (484 AD),signed by 2,500 Eastern bishops:
“[We agree that] in the Apostolic See the Catholic Religion is always kept immaculate. . . . We receive and approve all the letters of the blessed Pope Leo . . . and, as we have said, we follow the Apostolic See in everything and teach all its laws. Therefore, I hope that I may deserve to be with you [Pope Hormisdas] in that one Communion taught by the Apostolic See, in which Communion is the whole, real and perfect solidity of the Christian Religion. And I promise that in the future I will not say in the holy Mysteries the names of those who are banished from the Communion of the Catholic Church, that is, who do not agree with the Apostolic See.”
