Is this the same for ECs (within the EC Churches)?
From my experience, no.
In most EC parishes I have attended the ‘unknown’ persons strolling up for communion are assumed to be Latin Catholics. This destroys an important Orthodox practice but they are used to it by now.
Also, don’t some ROC people claim that in the EO order of precedence, they are higher than Constantinople (based on numbers of members)? I’m not attacking the ROC, remember…I actually like them alot. Just something I read.
The whole patriarchal system is a matter of practical administration.
In the beginning there were no patriarchs, it is an evolved system (what might be called discipline in the RC).
The earliest higher office we have good information on is the bishop of a metropolis … which is the major city of a province. So we have always called them the metropolitan bishop (or Archbishop). Patriarchs are just metropolitans, but the ‘inner circle’ of patriarchs are of the ancient mother churches which sent out missionaries. These were once great cities and the Apostles and other disciples reached them at an early date so they provided leadership for the church when Christianity was a small and persecuted band numbered in hundreds and thousands, not in millions.
Constantinople was declared a leading patriarchal city when Constantine rebuilt the city as his new capital. It was a new city built specifically as a Christian community, pagan temples were not allowed. It was the new Rome and a commercial center and quickly became quite large.
In fact, the reason why the First Ecumenical Council was held at Nicea was that the city of Constantinople was not ready.
So we can see that the church was using practical criteria to determine the order of precedence and was willing to reorder itself under changing conditions.
Even so, all patriarchs are still limited in direct authority to the bounds of their own synods, so there is no tradition of one synod being in submission to another. In fact, the early church fathers were always aware of this as a potential problem.
There is the famous case of the patriarch of Antioch claiming authority over the island of Cyprus. An Ecumenical Council rebuked the patriarch, declared that the church of Cyprus was to evermore be completely free of the control of outside churches, and warned that all other churches should take care to guard against this practice.
Canon 8 of Ephesus [abbreviated] reads:
…The same rule shall be observed in the other dioceses and provinces everywhere, so that none of the God beloved Bishops shall assume control of any province which has not heretofore, from the very beginning, been under his own hand or that of his predecessors.
But if any one has violently taken and subjected [a Province], he shall give it up; lest the Canons of the Fathers be transgressed; or the vanities of worldly honour be brought in under pretext of sacred office; or we lose, without knowing it, little by little, the liberty which Our Lord Jesus Christ, the Deliverer of all men, hath given us by his own Blood.
Wherefore,
this holy and ecumenical Synod has decreed that in every province the rights which heretofore, from the beginning, have belonged to it, shall be preserved to it, according to the old prevailing custom, unchanged and uninjured: every Metropolitan having permission to take, for his own security, a copy of these acts. And if any one shall bring forward a rule contrary to what is here determined, this holy and ecumenical Synod unanimously decrees that it shall be of no effect!
Thus neither the patriarch of Antioch, the patriarch of Constantinople nor the patriarch of Rome would ever be allowed to control that church or others like it.
The order of precedence is a secondary matter, it does not effect the administration of the church, the church in Russia is self-headed, but much larger than the church at Constantinople. In fact almost all Orthodox churches are larger than the one at Constantinople these days. Some people are making the argument that the church needs to reevaluate the order of precedence, which, after all is a discipline of the church and can be changed.
