Mark, a translator of Peter, was sent (think apostle) to the Hebrews of Alexandia, Egypt by John the Apostle AFTER having borne the Gospel of Peter (now called the gospel of Mark) and the Gospel of Paul (now called Hebrews, but penned by Luke) to John in Ephesus of Asia – in the ministry of being an messenger (after the same special ministry Phoebe was an"angel" in bearing the book of Romans from Jerusalem to the Corinthian missionaries in Rome, pre-Peter and pre-Paul).
Cite the source of his information. Though his findings are rather questionable, my Catholic friend.
Hence, having been sanctified by John, and earlier by Paul (as being sent for as profitable to his ministry), even if Mark did not get approval from Peter – nor resistance, he was an equal to Clement. Paul was that co-founding Apostle of the Churches of Rome, whose disciple – Clement – perpetuated the Churches at Rome (that is, not Peter’s, but Paul’s disciple who sat upon the “holy see”) for 43-44 years (from May 57 to 100/101 A.D.) That is…with the death of Anacletus, the Apostolic Succession of Peter CEASED in ROME, and for 19 1/2 centuries, the Roman Catholic Church has cursed its origin in Paul.
I have just read Mike Aquilina’s book on the ECF and none of it mention that Paul sat on the Holy See, nor have I read any ECF saying that Paul was the Bishop.
The following ECF seem to disagree with your friend. Historically speaking, your friend is in error.
Tatian the Syrian
“Simon Cephas answered and said, ‘You are the Messiah, the Son of the living God.’ Jesus answered and said unto him, ‘Blessed are you, Simon, son of Jonah: flesh and blood has not revealed it unto thee, but my Father which is in heaven. And I say unto thee also, that you are Cephas, and on this rock will I build my Church; and the gates of hades shall not prevail against it” (The Diatesseron 23 [A.D. 170]).
“Was anything withheld from the knowledge of Peter, who is called ‘the rock on which the Church would be built’ [Matt. 16:18] with the power of ‘loosing and binding in heaven and on earth’ [Matt. 16:19]?” (Demurrer Against the Heretics 22 [A.D. 200]).
“[T]he Lord said to Peter, ‘On this rock I will build my Church, I have given you the keys of the kingdom of heaven [and] whatever you shall have bound or loosed on earth will be bound or loosed in heaven’ [Matt. 16:18–19]. . . . What kind of man are you, subverting and changing what was the manifest intent of the Lord when he conferred this personally upon Peter? Upon you, he says, I will build my Church; and I will give to you the keys” (Modesty 21:9–10 [A.D. 220]).
The Letter of Clement to James
“Be it known to you, my lord, that Simon [Peter], who, for the sake of the true faith, and the most sure foundation of his doctrine, was set apart to be the foundation of the Church, and for this end was by Jesus himself, with his truthful mouth, named Peter” (Letter of Clement to James 2 [A.D. 221]).
Cyprian of Carthage
"The Lord says to Peter: ‘I say to you,’ he says, ‘that you are Peter, and upon this rock I will build my Church, and the gates of hell will not overcome it. And to you I will give the keys of the kingdom of heaven . . . ’ [Matt. 16:18–19]. On him [Peter] he builds the Church, and to him he gives the command to feed the sheep [John 21:17], and although he assigns a like power to all the apostles, yet he founded a single chair [cathedra], and he established by his own authority a source and an intrinsic reason for that unity. Indeed, the others were that also which Peter was , but a primacy is given to Peter, whereby it is made clear that there is but one Church and one chair. . . . If someone does not hold fast to this unity of Peter, can he imagine that he still holds the faith? If he [should] desert the chair of Peter upon whom the Church was built, can he still be confident that he is in the Church?" (The Unity of the Catholic Church 4; 1st edition [A.D. 251]).
