I will dispute that the Bishop of Rome presided over the whole Church…this notion of Papal Supremacy just didn’t exist then.
Then your dispute is not with me, but with those Saints and Martyrs who give witness to the authority of Peter’s Chairs presided by the Bishop of Rome alone. I can agree that the early Church was free from secular powers and the Bishop of Rome’s authority was not viewed in a secular way as it does later when the persecution is lifted. But you cannot refute the faith of the Early Church Father’s pre-Constantinople period, who declared the Bishop of Rome who presides in the Chair of Peter, settling all disputes over the whole Church.
An example from a list too many early Church Father’s to list here;
Ignatius of Antioch
“Ignatius . . . to the church also which holds the presidency, in the location of the country of the Romans, worthy of God, worthy of honor, worthy of blessing, worthy of praise, worthy of success, worthy of sanctification, and, because you hold the presidency in love, named after Christ and named after the Father” (Letter to the Romans 1:1
[A.D. 110]).
“You [the church at Rome] have envied no one, but others you have taught. I desire only that what you have enjoined in your instructions may remain in force” (ibid., 3:1).
Irenaeus
“But since it would be too long to enumerate in such a volume as this the succession of all the churches, we shall confound all those who, in whatever manner, whether through self-satisfaction or vainglory, or through blindness and wicked opinion, assemble other than where it is proper, by pointing out here the successions of the bishops of the greatest and most ancient church known to all, founded and organized at Rome by the two most glorious apostles, Peter and Paul, that church which has the tradition and the faith which comes down to us after having been announced to men by the apostles. With that church, because of its superior origin, all the churches must agree, that is, all the faithful in the whole world, and it is in her that the faithful everywhere have maintained the apostolic tradition” (Against Heresies 3:3:2 [
A.D. 189]).
