You insist on calling it ‘consensus,’ which is not supported by the evidence.
I disagree. Again, if it were otherwise, why were they writing to him to explain
what they had already done? It would be rather silly to call a council, make all kind of decisions, decrees, pronouncements, etc. and then write to the Roman Pope in hopes that he’ll ratify them. What if he doesn’t? “Whoops. Sorry for coming out, everybody! Sorry for several of you dying on the way here! I guess we all wasted our time and money because Rome does not agree!” Again, Rome didn’t agree with the Quinisext Council, nor with all of the canons of Constantinople I, yet Constantinople is accepted today as an ecumenical council by the Orthodox and the Roman Catholic Church, and the Quinisext Council forms the basis of Eastern Orthodox canon law (and was accepted by the Eastern bishops over a century before the tragic events of 1054). So I’m afraid the picture you are painting is an overly simplistic one.
“…having examined…has given witness…” means you considered the facts and made a determination based on the facts. ‘Complete agreement’ may be accurate. It means, without the Pope’s agreement, the matter was not settled.
See above for two counterexamples to this idea. I know Rome is the center of your ecclesiastical universe, but it is not so for all of us.
When you said you never suggested the Pope’s opinion was irrelevant or offensive it became clear you misunderstood what I wrote, which is why I repeated it. I was making an argument from logic and deductive reasoning. Having repeated it, you still seem not to know what I said, so let’s just drop it.
Okay.
The ‘Roman pope’ is in quotes because it’s the term you used, which most Catholics find derisive. We never use that ‘title.’ You may be using it as a distinction from the Coptic pope, but I think we can agree that isn’t necessary in this conversation.
I’m actually using it in a geographical sense, not ecclesiastical (I agree that it would not make sense to use it in an ecclesiastical sense to refer to times prior to the Chalcedonian schism; we were one church at the time of Constantinople). “Pope” is a title that has an interesting history which cannot be attributed to Rome alone, either historically or currently. I don’t particularly like the phrase “Coptic Pope”, either, as ‘Copt’ (unlike ‘Roman’) is an ethno-linguistic term, and not all popes have been ethnic Copts. Some have been Syrians, just as in the case of the Roman papacy. In the context of our conversation, which is addressing the subject of the proper ecclesiastical boundaries and application of Roman (Papal) authority at the time of the early councils, it is entirely appropriate to emphasize that he is the Pope of
Rome in order to emphasize my belief, which is the Orthodox belief, that every Patriarch has a particular canonical territory which is within his governance, i.e., there is no universal jurisdiction.
The Council informed the Pope of its actions because the Pope’s ratification was the only way those actions would have an effect on the universal Church and be carried into the future.
No. Plenty of things that the Roman Popes have approved of were not taken up by the rest of the church: clerical celibacy, Papal supremacy, Papal Petrine exclusivism (e.g., the apparent belief that the Roman See is the sole See of Peter, to the exclusion of Antioch), many modern dogmas, etc. The Roman Pope is not the be all and end all of the faith. The sad case of Honorius should be more than enough of an example of why that can’t be so.
You seem to think all this correspondence was just polite chatter with no substance. If that’s what you think, I think you’re wrong.

God bless you.
No, no, no…you seem to think that’s what I think, but that’s not what I think. I’ve addressed this already, but just to be absolutely clear: The conciliar model of early church governance (which is to say,
the model of early church governance)
included the Pope of Rome during Rome’s orthodox period. So it wasn’t just a formality or a pleasantry on the part of other bishops that they should seek his support. Just the same, as several examples have already shown, he wasn’t the be-all and end-all of Church governance, just as St. Peter, who is recognized as foremost among the apostles by the Orthodox Church, was not the expositor of the faith at the Apostolic Council in Jerusalem, where he was withstood by St. Paul for his acceptance (temporarily) of the Judaizing tendencies popular in the Church at that time.
