(I know it’s a lot, but this is the final one…)
“Peter is again called 'the coryphaeus of the Apostles.’” *Basil of Seleucia, Oratio 25 (ante A.D. 468). *
“The holy Roman Church is senior to the other churches not by virtue of any synodal decrees, but obtained the primacy from Our Lord and Savior in the words of the Gospel, ‘Thou art Peter…’” *Pope Gelasius, Decree of Gelasium (A.D. 492). *
“[T]he statement of Our Lord Jesus Christ who said, ‘Thou art Peter, and upon this rock I will build my Church,’…These (words) which were spoken, are proved by the effects of the deeds, because in the Apostolic See the Catholic religion has always been preserved without stain.’” *Pope Hormisdas, Libellus professionis fidei, (A.D. 519). *
“To Peter, that is, to his church, he gave the power of retaining and forgiving sins on earth.” *Fulgentius, De Remissione Peccatorum, 2:20 (A.D. 523). *
“Who could be ignorant of the fact that the holy church is consolidated in the solidity of the prince of the Apostles, whose firmness of character extended to his name so that he should be called Peter after the ‘rock’, when the voice of the Truth says, ‘I will give to thee the keys of the kingdom of heaven’. To him again is said "When after a little while thou hast come back to me, it is for thee to be the support of thy brethren.” *Pope Gregory the Great, Epistle 40 (A.D. 604). *
“The decrees of the Roman Pontiff, standing upon the supremacy of the Apostolic See, are unquestionable.” *Isidore of Seville, (ante A.D. 636). *
“For the extremities of the earth, and all in every part of it who purely and rightly confess the Lord, look directly towards the most holy Roman Church and its confession and faith, as it were a sun of unfailing light, awaiting from it the bright radiance of our fathers, according to what the six inspired and holy Councils have purely and piously decreed, declaring most expressly the symbol of faith. For from the coming down of the Incarnate Word among us, all the churches in every part of the world have possessed that greatest church alone as their base and foundation, seeing that, according to the promise of Christ Our Savior, the gates of hell do never prevail against it, that it possesses the Keys of right confession and faith in Him, that it opens the true and only religion to such as approach with piety, and shuts up and locks every heretical mouth that speaks injustice against the Most High.” *Maximus the Confessor, Opuscula theologica et polemica (A.D. 650). *
“Peter was pronounced blessed by the Lord…the duty of feeding the spiritual sheep of the Church under whose protecting shield, this Apostolic Church of his has never turned away from the path of truth in any direction of error, whose authority, as that of the Prince of all the Apostles, the whole Catholic Church and the Ecumenical Synods have faithfully embraced…” *Pope Agatho, To Ecumenical Council VI at Constantinople, (A.D. 680). *
"A copy of the letter sent by the holy and Ecumenical Sixth Council to Agatho, the most blessed and most holy pope of Old Rome…Therefore to thee, as to the bishop of the first see of the Universal Church, we leave what must be done, since you willingly take for your standing ground the firm rock of the faith, as we know from having read your true confession in the letter sent by your fatherly beatitude to the most pious emperor: and we acknowledge that this letter was divinely written (perscriptas) as by the Chief of the Apostles, and through it we have cast out the heretical sect of many errors which had recently sprung up…” *Constantinople III, Council to Pope Agatho, (A.D. 680). *
“For, although the devil desired to sift all the disciples, the Lord testifies that He Himself asked for Peter alone, and wished that the others be confirmed my him; and to Peter also was committed the care of ‘feeding the sheep’(John 21:15);and to him also did the Lord hand over the ‘keys of the kingdom of heaven’(Matthew 16:19),and upon him did He promise to ‘build His Church’ (Matthew 16:18);and He testified that ‘the gates of Hell would not prevail against it’ (Matthew 16:19).” *Pope Pelagius II, Quod Ad Dilectionem (c. A.D. 685). *“‘Thou art Peter, and upon this rock I will build my church, and the gates of hell shall not prevail against it, and to thee I will give the keys of the kingdom of heaven’? When Wilfrid spoken thus, the king said, ‘It is true, Colman, that these words were spoken to Peter by our Lord?’ He answered, ‘It is true O king!’ Then says he, ‘Can you show any such power given to your Columba?’ Colman answered, ‘None.’ Then added the king, "Do you both agree that these words were principally directed to Peter, and that the keys of heaven were given to him by our Lord?’ They both answered, ‘We do.’” Venerable Bede, (A.D. 700), Ecclesiastical History, 3:5 (A.D. 700).
