A presbyterian, and two Anglicans:
“…it can hardly be denied that the document [Clement to the Corinthians] reveals the sense of a certain superiority over all ordinary congregations. The Roman church here, without being asked (as far as appears), gives advice, with superior administrative wisdom, to an important church in the East, dispatches messengers to her, and exhorts her to order and unity in a tone of calm dignity and authority, as the organ of God and the Holy Spirit. This is all the more surprising if St. John, as is probable, was then still living in Ephesus, which was nearer to Corinth than Rome.” (Philip Schaff, History of the Christian Church, volume 2 [1910], page 158)
“Everywhere, in the East no less than the West, Rome enjoyed a special prestige, as is indicated by the precedence accorded without question to it…Thus Rome’s preeminance remained undisputed in the patristic period. For evidence of it the student need only recall the leading position claimed as a matter of course by the popes, and freely conceded to them, at the councils of Ephesus (431) and Chalcedon (451)…It goes without saying that Augustine [c. 354 - 430 AD] identifies the Church with the universal Catholic Church of his day, with its hierarchy and sacraments, and with its centre at Rome…By the middle of the fifth century the Roman church had established, de jure as well as de facto, a position of primacy in the West, and the papal claims to supremacy over all bishops of Christendom had been formulated in precise terms…The student tracing the history of the times, particularly of the Arian, Donatist, Pelagian and Christological controversies, cannot fail to be impressed by the skill and persistence with which the Holy See [of Rome] was continually advancing and consolidating its claims. Since its occupant was accepted as the successor of St. Peter, and prince of the apostles, it was easy to draw the inference that the unique authority which Rome in fact enjoyed, and which the popes saw concentrated in their persons and their office, was no more than the fulfilment of the divine plan.” (JND Kelly, Early Christian Doctrines, pages 406, 407, 413, 417)
"Unquestionably, the Roman church very early developed something like a sense of obligation to the oppressed all over Christendom…Consequently there was but one focus of authority…To Christians of the Occident, the Roman church was the sole, direct link with the age of the New Testament and its bishop was the one prelate in their part of the world in whose voice they discerned echoes of the apostles’ speech. The Roman bishop spoke always as the guardian of an authoritative tradition, second to none. Even when the eastern churches insisted that their traditions were older and quite as sacred, if not more so, the voice in the West, unaccustomed to rivalry at home, spoke on regardless of protest or denunciation at a distance…
"The Roman See, as distinct from the Roman church, was and ought to be predominant, not for its situation or other worldly advantages, not even for its treasure of doctrine, bequeathed by its two founders [Peter and Paul], but, primarily and fundamentally, because its bishop was heir in his own person to the unique prerogative conferred upon Peter. To Peter had been granted a primacy among the apostles, so to the Roman bishop was assigned a leadership over the bishops…
“The Arians, who had ousted Athanasius from Alexandria, offered to submit the case to [Pope] Julius for his judgment. Athanasius himself and other orthodox refugees from eastern sees went directly to Rome as to a court of appeal…From the time when Eleutherus was asked to condemn the Montanists, through the period when Callistus, Stephen and Dionysius revised and interpreted dogma, down to the days when the Nicene creed was defended on the ground of its Roman origin and Liberius and Damasus endorsed or rejected eastern declarations of faith according as they did or did not measure up to their own standards, the Roman bishops asserted their right to speak for the tradition of Peter.” (Shotwell/Loomis, The See of Peter, page 217-228)
