After all these [writings of] the prophets and the evangelical and apostolic scriptures which we discussed above, on which the catholic church is founded by the grace of God, we also have thought necessary to say what, although the universal catholic church diffused throughout the world is the single bride of Christ, however the holy Roman church is given first place by the rest of the churches without [the need for] a synodical decision, but from the voice of the Lord our saviour in the gospel obtained primacy: 'You are Peter,' he said, 'and upon this rock I shall build my church and the gates of hell shall not prevail against it; and to you I give the keys of the kingdom of heaven, and whatever you shall bind upon Earth shall be bound also in heaven and whatever you release upon Earth shall also be released in heaven'.
In addition there is also the presence of the blessed apostle Paul, 'the chosen vessel', who not in opposition, as the heresies jabber, but on the same date and the same day was crowned in glorious death with Peter in the city of Rome suffering under Nero Caesar; and equally they made the above-mentioned holy Roman church special in Christ the Lord and gave preference in their presence and veneration-worthy triumph before all other cities in the whole world.
Therefore first is the seat at the Roman church of the apostle Peter 'having no spot or wrinkle or any other [defect]'.
However the second place was given in the name of blessed Peter to Mark his disciple and gospel-writer at Alexandria, and who himself wrote down the word of truth directed by Peter the apostle in Egypt and gloriously consummated [his life] in martyrdom.
Indeed the third place is held at Antioch of the most blessed and honourable apostle Peter, who lived there before he came to Roma and where first the name of the new race of the Christians was heard.
