Sherlock:
I am having a discussion with a Lutheran who says that the Church Fathers, pre-Constantine, did hold the Church of Rome to be authorative. I gave him Clement’s epistle to the Corinthians, and pointed out the very authorative laguage used. He countered with: "You forget one thing…church of Corinth were under direct jurisdiction of church in Rome at the time.
Here is a link to a number of early writings:
web.globalserve.net/~bumblebee/ecclesia/patriarchs.htm
St. Peter, Bishop of Alexandria (306-311 A.D.):
Head of the catechetical school in Alexandria, he became bishop around A.D. 300, reigning for about eleven years, and dying a martyr’s death.
Peter, set above the Apostles. (Peter of Alexandria, Canon. ix, Galland, iv. p. 98)
St. Athanasius (362 A.D.):
Rome is called the Apostolic throne. (Athanasius, Hist. Arian, ad Monach. n. 35).
The Chief, Peter. (Athan, In Ps. xv. 8, tom. iii. p. 106, Migne)
St. John Chrysostom, Patriarch of Constantinople (c. 387):
Peter himself the Head or Crown of the Apostles, the First in the Church, the Friend of Christ, who received a revelation, not from man, but from the Father, as the Lord bears witness to him, saying, ‘Blessed art thou, &c.’ This very Peter and when I name Peter I name that unbroken Rock, that firm Foundation, the Great Apostle, First of the disciples, the First called, and the First who obeyed he was guilty …even denying the Lord." (Chrysostom, T. ii. Hom)
Peter, the Leader of the choir of Apostles, the Mouth of the disciples, the Pillar of the Church, the Buttress of the faith, the Foundation of the confession, the Fisherman of the universe. (Chrysostom, T. iii Hom).
(Peter), the foundation of the Church, the Coryphaeus of the choir of the Apostles, the vehement lover of Christ …he who ran throughout the whole world, who fished the whole world; this holy Coryphaeus of the blessed choir; the ardent disciple, who was entrusted with the keys of heaven, who received the spiritual revelation. Peter, the mouth of all Apostles, the head of that company, the ruler of the whole world. (De Eleemos, iii. 4; Hom. de decem mille tal. 3)
And why, then, passing by the others, does He converse with Peter on these things? (John 21:15). He was the chosen one of the Apostles, and the mouth of the disciples, and the leader of the choir. On this account, Paul also went up on a time to see him rather than the others (Galatians 1:18). And withal, to show him that he must thenceforward have confidence, as the denial was done away with, He puts into his hands the presidency over the brethren. And He brings not forward the denial, nor reproches him with what had past, but says, 'If you love me, preside over the brethren, …and the third time He gives him the same injunction, showing what a price He sets the presidency over His own sheep. And if one should say, ‘How then did James receive the throne of Jerusalem?,’ this I would answer that He appointed this man (Peter) teacher, not of that throne, but of the whole world. (Chrysostom, In Joan. Hom. 1xxxviii. n. 1, tom. viii)
There are thousands and thousands of instances.
