Contra-Catholic Revisionist History.
Protestan Patristic scholar J.N.D. Kelly in his classic work Early Christian Doctrines sums up how unanimous the Church was in the patristic period, evidence becomes overwhelming for the primacy and authority of the Romean Church -- "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). We even find the fifth-century historians Socrates and Sozomen concluding...that it was unconstitutional for synods to be held without the Roman pontiff being invited or for decisions to be taken without his concurrence. At the outbreak of the Christological controversy, it will be remembered, both Nestorius and Cyril hastened to bring their cases to Rome, the latter declaring that the ancient custom of the churches constrained him to communicate matters of such weight to the Pope and to seek his advice before acting. In one of his sermons he goes so far as to salute Celestine as 'the archbishop of the whole world' .....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....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." (Kelly, pages 406, 407, 413, 417)
Protestant scholar John Lawson’s work The Biblical Theology of St. Irenaeus had this to say about the Bishop of Lyons and his view of the Roman church and its primacy:
[W]hat church can compare with Rome? She is the life-work of the two greatest Apostles, known of all and knowing all, she is a supreme witness to the unified voice of the Church. If it is necessary for each and all to consent to the voice of the whole Church, how necessary is it for all to consent to Rome? To S. Irenaeus Rome was most certainly an authority none must question, as she cannot be imagined as ever in error. The word ‘infallible’ to some extent begs the question, for the use of it imports into the discussion the results of later definition. It is nevertheless a word which is difficult to do without. With this proviso we may say that Irenaeus regarded Rome as the very corner-stone and typification of a whole structure of ecclesiastical infallibility. The Church and Infallibility by B.C. Butler pgs. 136-137 (c. 1954
Protestant Historical scholar Harnack recognizes the original teacher here.
Ignatius is our first external witness in regard to the Roman Church in 110AD. After making allowances for exaggeration of language in his letter to the Romans, it remains clear that Ignatius assigns a de facto primacy to the Roman Church among its sister churches and that he knew of an energetic and habitual activity of this church in protecting and instructing other churches. The Church and Infallibility pg. 140 (c. 1954
Taking into account the phenomenon of development, the notion of primacy needs to be established first. The Church of Rome enjoyed a Primacy over the other Churches from the earliest period for which we have records with indications that this priority was not an innovation. Dr. Harnack claimed that "The Roman Church from the end of the first century possessed a de facto primacy in Christendom" (Mission und Ausbreitung pg. 398).

CHAPTER IV:
In the external organization of the church, several important changes appear in the post apostolic period before us. The distinction of clergy and laity, and the sacerdotal view of the ministry becomes prominent and fixed; subordinate church offices are multiplied; the episcopate arises; the beginnings of the Roman primacy appear; and the exclusive unity of the Catholic church develops itself in opposition to heretics and schismatics. The apostolical organization of the first century now gives place to the old Catholic episcopal system.

I cited the testimony of Protestant Historical scholars acknowledging that the Catholic position was the one espoused in the ancient Church of the late first Century and throughout much of the 1500 years before the Reformation
