Regarding the language of Canon VI, I contend your conclusion of the language is specious (not to mention that interpretation does not fit with the primacy of the Roman Church both before and after Nicea in 325.
There was no such thing as "primacy of the Roman Church" as Rome later laid claim to.
A good treatment by Mark Bonocore (
full article):
"Let the ancient customs in Egypt, Libya, and Pentapolis prevail that the Bishop of Alexandria has jurisdiction in all these, since **the like** is customary for the Bishop of Rome also. Likewise, in Antioch and the other provinces, let the churches retain their priveledges." (Nicaea, Canon 6).
Now, ... Here we see the "big three" one again. ...And they are spoken about as if they have always (Traditionally) been in place. Also, ... There has been much ink spilled over the phrase "the like" when refering to Rome above. Is Nicaea saying that Alexandria has local jurisdiction because Rome has similar local jurisdiction? Or, is Nicaea saying that Alexandria has jurisdiction in Egypt, Libya, and Pentapolis BECAUSE it is the custom of the Roman Church that Alexandria holds jurisdiction here? ...That Rome recognizes the local jurisdiction of Alexandria ...and of Antioch as well?

Well, ... I say it's the latter. And, again ... See the quote from Pope Damasus:
"The first see, therefore, is that of Peter the Apostle, that of the Roman church, which has neither stain nor blemish, nor anything like that. The second see is that of Alexandria, consecrated on behalf of the blessed Peter by Mark, his disciple and an Evangelist, who was sent to Egypt by the Apostle Peter, where he preached the word of truth and finished his glorious martyrdom. The third see is that of Antioch, which belonged to the most blessed Peter, where first he dwelled before he came to Rome, and where the name "Christians" was first applied, as to a new people." (Decree of Damasus # 3, 382 A.D.)
See also the Epistle of Pope Julius I (A,D. 342) ...a contemporary of Nicaea itself ...where he writes to the Byzantine court to complain about St. Athanasius and St. Marcellus when they were deposed by the Arians from their sees of Alexandria and Antioch, respectfully:
"It behoved you to write to us that thus what is just might be decreed for all. For they who suffered were bishops, and the Churches that suffered no common ones, over which the Apostles ruled in person. And why were we (the Pope) not written to concerning the Church, *****especially Alexandria*****? Or are they (the Arians) ignorant that ****this has been the custom first to write to us, and thus what is just be decreed from this place (Rome)*****? If therefore, any such suspicion fell upon the bishop there (Alexandria), it was benefitting to write to this Church (Rome)." (Julius, Ep. n. 6,21.)
So, again, we have Rome defending the Traditional set up. And Julius' statement that Rome has authority to give rulings over Alexandria (the 2nd See) places Canon 6 of Nicaea into its proper context. The jurisdiction of Alexandria (over Egypt, Libya, and Pentapolis) was recognized by the Council ***because*** that was the custom of Rome (i.e., Peter --when at Rome --had sent his disciple Mark to preside over Alexandria, allowing that see to participate in the Petrine ministry of Rome through ties of discipleship).
At the end of the day, one has to read into the phrase "the like" in Canon VI from Nicea to mean equality in authority, and the text neither confirms nor excludes that as the meaning. But in historical context, it can be seen that Nicea was not defining equality of authority among Rome, Alexandria, and Antioch.
Well, of course Bonocore is going to present the Roman spin on the subject.
At the very least, I think you have helped show that the only serious Churches to even be considered as the true Church Christ set up are the Catholic and Orthodox.
Wrong again! You have cut and pasted Roman Catholic spin is all you have done.
Now for the facts.
The authority given to Peter was given to all the Apostles and in turn, to all believers.
1.There are no explicit references to a papacy in the earliest centuries of Christianity. Catholic apologists often suggest that a papacy is alluded to in
Matthew 16,
John 21, First Clement, Against Heresies, and other early documents, but all of these documents can reasonably be interpreted in non-papal ways. There are explicit references to the church offices of bishop and deacon, as well as doctrines such as Christ's deity, the Trinity, and the eucharist, but there aren't any explicit references to a papacy.
2. Many of the words and actions of the earliest Christians contradict the concept of a papacy. The disciples repeatedly argued about who was the greatest among them, even after the words of
Matthew 16:18-19 were spoken (
Luke 22:24). The disciples don't seem to have had any concept of Peter having been established as their ruler. Paul wrote about apostles (plural), not a Pope, being the highest order in the church (
1 Corinthians 12:28). He also wrote that, in terms of apostolic authority, he was in no way inferior to any other apostle (
2 Corinthians 12:11). Many events in early post-apostolic church history, such as Polycarp's disagreements with the Roman bishop Anicetus and Cyprian's disagreements with the Roman bishop Stephen, also contradict the concept of a papacy (
http://members.aol.com/jasonte2/denials.htm).
3. The earliest non-Christian sources who commented on Christianity said nothing about a papacy. Though Pliny the Younger, Celsus, Lucian, and other early non-Christian sources wrote about the eucharist, Christ's deity, and other Christian doctrines, they didn't say anything about a papacy. If one man was viewed as the ruler of all Christians on earth, the "Vicar of Christ" and "Bishop of bishops", he would have been an ideal object of criticism. None of the earliest non-Christian sources seem to have any concept of a papacy, though.
4. The earliest interpretations of the scripture passages most often cited in favor of a papacy are all non-papal. Tertullian (On Modesty, 21) writes that Peter was the "rock" of
Matthew 16:18 in the sense that he played a major role in founding the Christian church. He identifies the usage of the "keys" of
Matthew 16:19 not as papal authority, but as the preaching of the gospel and the exercising of church discipline. Origen (Commentary on Matthew, 10-11) writes that everybody who confesses the faith Peter confessed in
Matthew 16:18 is also a "rock". He emphasizes that
Matthew 16:18 doesn't apply only to Peter, and he says nothing about this passage applying in any exclusive way to the bishops of Rome. Cyprian (Epistle 26) writes that all bishops, not just the bishop of Rome, are the successors of Peter, so that
Matthew 16:18 applies to all of them. The Apostolical Constitutions (6:5) refers to
Luke 22:32 as a passage about the faith of all Christians, and says nothing of a papacy or of this passage referring to papal infallibility. Cyril of Alexandria, John Chrysostom, Augustine, and other church fathers also interpreted
Matthew 16,
Luke 22, and
John 21 in non-Roman-Catholic ways. Some church fathers even applied multiple interpretations to these passages of scripture, but the earliest church fathers never applied the Roman Catholic interpretations to these passages.
5. Men like Clement of Alexandria (The Stromata), Cyprian (On the Unity of the Church), and Augustine (Sermons) wrote entire treatises relating to church government and Christian doctrine without mentioning a papacy. Offices such as bishop and deacon are mentioned over and over again, councils are discussed, and the authority of scripture is referred to again and again, yet nobody in the earliest centuries of Christianity writes about papal authority. There are treatises instructing Christians on how to interpret scripture, explaining how to view doctrines like the incarnation and the Trinity, and encouraging Christians to obey bishops and other church leaders. There are no treatises devoted to a papal office, though, nor is a papacy even mentioned. For example, the influential bishop of Carthage, Cyprian, wrote a treatise on church government and unity (On the Unity of the Church) that not only doesn't mention a papacy, but even contradicts the concept.
Not only did many church fathers not see Peter as the "rock", but some, such as Jerome and Augustine, even changed their interpretation of
Matthew 16:18 from time to time. This was a passage considered to be open to multiple interpretations, with the interpretation of "rock" not considered a matter of much importance. Obviously, the early church didn't see this passage as the foundation for a papal office. Origen, commenting on
Matthew 16 early in the third century, reflects the early church's ignorance of the papal interpretation of the passage:
And if we too have said like Peter, "Thou art the Christ, the Son of the living God," not as if flesh and blood had revealed it unto us, but by light from the Father in heaven having shone in our heart, we become a Peter, and to us there might be said by the Word, "Thou art Peter," etc. For a rock is every disciple of Christ of whom those drank who drank of the spiritual rock which followed them, and upon every such rock is built every word of the church, and the polity in accordance with it; for in each of the perfect, who have the combination of words and deeds and thoughts which fill up the blessedness, is the church built by God. But if you suppose upon the one Peter only the whole church is built by God, what would you say about John the son of thunder or each one of the Apostles? Shall we otherwise dare to say, that against Peter in particular the gates of Hades shall not prevail, but that they shall prevail against the other Apostles and the perfect? Does not the saying previously made, "The gates of Hades shall not prevail against it," hold in regard to all and in the case of each of them? And also the saying, "Upon this rock I will build My church"? (Commentary on Matthew, 10-11)
