I find that the underlining of differences between the Apostolic Churches is psychological in nature. I believe our differences are stressed over our similarities is because it’s much easier to discuss our differences and similarities. Having a conversation where the other side just nods and says “Yep, that’s right, I agree” doesn’t last very long, and once you both have reached full agreement, what point is there in further discussing the topic?
However, with differences, that provides a much livelier discussion, with each side challenging the other’s ideas. The question of who’s right becomes a puzzle that needs to be solved. And people love puzzles. Solving puzzles means progress.
And a definite progress is discerning that both can be considered right, and getting through that, building on every contribution, a higher and common point of view.
Let us thank the Lord for our already manifest extraordinary commonalities !
I think we’re agreed on the indefectible part, but inherent is still up in the air for me, if only because we would have to then define how indefectibility is inherent and what the implications of that are.
A not inherent indefectibility would mean a quality the Church can loose. An indefectibility which can be lost …is not indefectibility. Should we believe that Jesus’ message can be lost before His second coming ?
See what I bolded? That’s always the copout whenever someone brings up an event that challenges the dogma of Papal Infallibility. The idea that “Oh, well if they taught something wrong, then they weren’t authoritatively teaching” is simply a No True Scotsman fallacy. If the Pope or a Council teaches error, you handwave it and say “Oh, well, they didn’t teach it authoritatively.” Well, how do we define “authoritatively?” What does that mean, and how can we tell when something is “authoritatively” taught?
Throwing infallibility into the mix doesn’t help anything. How do we know when the Pope or a Council is infallible and when it isn’t? Because they clearly aren’t always infallible.
Speaking about infallibilty, consider please that there is no a priori reason to single out the Pope, or whatever organ. A No True Scotsman game can be played about any organ or source of infallibility.

And it can be played even about the inerrancy of the Scriptures. What is the precise scope of biblical inerrancy ? The Church is still working on that question, as I understand. So Christians could be charged with making inerrancy a mobile target.
Are we going then to throw away biblical inerrancy ? Or are we going to throw away ecclesial infallibility because of that ?
Infallibility has other problems, deeper that the True Scotsman game.
Namely, that I have to discern the infallible source ( whatever it is, the Toronto Star say ) fallibly.
Then I have to interpret its statements fallibly. That is IMHO a critique we should all consider.
So it is important IMHO fixing whether a given difficulty we may have concerns a specific organ of infalliblity, or infallibility in itself.
As for the definition of the scope of the expression of ecclesial infallibility through the pope, I guess the answer is in Pastor Aeternus. We also know that the scope is the same,
ratione materiae, for Ecumenical Councils, and that in such solemn gatherins the college must be united with its head.
And no, there is no irreformable complete list of irreformable statements .
I am under the impression that many Orthodox brothers do believe in ecclesial infallibility, in particular expressed though the organ of Ecumenical Councils. Is that correct ? I don’t know whether you are being taught this way.
How do we know that a particular Council is Ecumenical, and therefore infallible ?
Alright, nothing I haven’t already mentioned as part of my argument (except maybe Canon 4).
However, appellate universal jurisdiction is quite different from the universal jurisdiction that the Pope enjoys in the Catholic Church today.
Also note that the Bishop of Rome is never the initiator in any of those canons. He only acts (or refuses to) after being requested to. Even in canon 5, the Pope is never a judge in the bishop’s trial himself, but sends some priests to be judges with the rest of the bishops.
More accurately, per Canon 5 the Bishop of Rome has the power to be judge through legates.
Anyway we seem to agree that the the principle of universal jurisdiction was there in the first millennium. An appellate jurisdiction.
To honor St. Peter ( Canon 3), say the Fathers of Sardica. ( which does underline that the link between the bishop of Rome and Peter was perceived as unique ).
So universal jurisdiction cannot be anathema, in itself, it seems.
As I said before, the meaning of “confirm your brothers” needs to be agreed upon before you can pull that card.
See previous post please. Is your present difficulty about the meaning of “confirm your brothers”, or about the Popes being entrusted with that task after Peter ( or both ) ?
Please, do not explain away the unique role of the Apostolic See in preserving Orthodoxy through the upheavals to the IX century. (Try a mental experiment imagining those centuries without Rome and the West.

)
Define “officially.” This smells like another No True Scotsman.
I
s any adverb a No True Scotsman here ?

Seriously, the adverb is not the operative word . What I invite to consider is that the way the Council adresses the Pope seems to imply a belief in a sort of infallibility. Am I completely off target ?
Do you have the relevant part from Constantinople III?
See again previous post.
Oh, and Bishop Leo of Rome thinks Bishop Leo of Rome is right. SURPRISE!
Well I do not think I am exercising an infallible magisterium. Do you ? Leo did, we can infer, about his Tome. Is that irrelevant , in a thread about about ecclesial infallibility in the early church ? BTW, nobody told St. Leo he was a fool, to my poor knowledge.
As a general remark, the argument about what first millennium Popes would attribute to their own ministry, is not just about their own opinions ( on this part, if you are going to tell me that it is obvious that a pope in any century declares his ministry is
jure divino over all churches, or that Rome has a stainless record in orthodoxy, well, I’m OK. Let’s consider it within the obvious if we want

)
The fact is you don’t have routine rejections, or rebuking on that, by orthodox hierarchs. On the contrary, you sometimes have full reception by Easterners. ( I am not suggesting that words, and actions, were always consistent and linear through the centuries, far from that ). And that is what I hope that can be appropriately pondered by anyone.
Looking forward to your opinions on my opinions.
And here they were, for what they can help.

In Christ
