Your
ecclesiology,
authority of Patriarchs as well as
understanding of primacy
has changed.
Ekklesiastically, we still hold that the Church is the Communion of the (geographically) local Churches in Communion one with another…
Rome, instead, has made of Herself the one Church alone in whose Communion is found the Church…
We hold all Patriarchs to be the autocephalous Heads of the local Churches of which each is its Head, subject only to the discipline of the withdrawal of Communion by the Head(s) of the other Church(es) with whom the offending Church is in Communion…
Rome, instead, has now made of Herself the ultimate Authority over all the Patriarchs of all the other Churches in Her Communion alone, able to intervene in their “Sui-juris-icality” according to the sole judgement of the Roman Patriarch-Pope…
The EOC has always held the Primacy of the Pope to be a Primacy of Honor…
The Latin Church NOW has Primacy of Honor to mean the Supremacy of Her Own Authority…
The Latin Church has never been the definition of the Church incapable of error…
The Latin Patriarchate has never had authority over other Patriarchs…
And Papal Primacy has never meant Papal Supremacy over Christ’s Body…
We have never believed any of this from the beginnings…
So who has changed?
Yes, contrary to their own understanding of the Church… as per Orthodox wiki
Withdrawal of Communion is a disciplinary measure of one local Church against another, when they cannot resolve the matter directly - And it CAN become enjoined by other Churches, and indeed by all the Communions against the one offending Church… It creates a state of tension offering the offending Church an opportunity to repent from its transgression… ROCOR was out of Communion with many Churches in the EOC because She would not reconcile with the Moscow Patriarchate (for lots of reasons) - They reconciled in Moscow and all the Communions were in that action re-conjoined…
You do not understand it that way - The whole EOC withdrew its Communion from the Latin Church, and that Church alone could only understand that the EOC has departed from Rome and was no longer in Communion with the Source of Communion, the Church of the Chair of Peter… We see this as Ecclesiastical Pride, you see… You see it as God’s will in His Giving to Rome ALONE the defining Communion of His Body on earth…
We have never understood Rome in this manner…
We have always understood Christ alone as the Source of the Communion of the Churches that comprise His Body upon this earth…
Rome agrees, but adds that He Speaks through the Chair of Peter alone…
