An excellent example of petitio principii. You have already here assumed what it is you wish to prove.
Your petitio principii that is revealed here answers a posters question that is found from Sacred Scripture and practiced from Sacred Tradition via the Church councils.
I have not assumed to prove the view of Orthodoxy rejecting the Primacy of Peter.
What I would like see clarified here, the Orthodox view of the Primacy of Peter has to be the same Primacy of Peter which the Catholic Church believes it to be supported by Sacred Scripture, Sacred Tradition.
The Orthodox view of rejection comes post Constantinople not pre-Constantinople. Thirdly, what the Orthodox view of Peter’s Primacy is never an Apostolic Catholic view of the primacy of Peter in the Bishop’s of Rome united with all the apostolic successors.
Thus far all I have heard from Orthodoxy are false views of Peter’s primacy. The Orthodox play on words that come from the Magesterium of the Church such as “supreme”, “jurisdiction”, “infallible”, “Primacy”, “authority”, “power” takes on a whole different meaning for which these terms are applied from the Church.
For example; Infallibility is a doctrine that is applied to the apostolic teachings and revelations of God, that when the Pope’s (Peter) speak excathedra this doctrine protects the Popes from teaching error. As scripture proves when all the bishops united with Peter in Jesus presence not only has the power and authority to bind and loose on earth, yet from this unity (council) their findings ratified by the Popes are infallible without error.
I get the sense that when Orthodox and protestant christians view “infallibility” almost always arrive at a wrong conclusion that this doctrine makes the Pope’s impeccable or superhuman. The doctrine of infallbility falls upon the whole Church’s faith, that the revelations of Jesus Christ and the apostolic teachings handed down are infallible, when the Pope’s declare these same teachings “unchanged” they remain “infallible” without error in every age, language, people, culture, nations and tongue. The declaration is spoken excathedra from the chair of Peter the rock which cannot and does not change to the whole Church.
When the Popes write as theologians or scholars, these are not “ex-cathedra” documents binding on the whole church. These are teachings that point to the infallible teachings of Jesus Christ and the revelations of God to His Church. These points have to be made for those who have a wrong understanding of infallibility and who have been influenced by wrong interpretations of Church documents.
Such points as I have stated above, which are asked to be proven here and clarified by the Orthodox view.
**I am sharing from a Catholic perspective, so as to bring a Catholic’s understanding and clarification to the Orthodox view that rejects the primacy of Peter are many times rejecting what Catholics do not believe in the primacy of Peter. **
Peace be with you
