I thought the answer might be shared theology,
Well, yes it is. It is the received theology.
But it is the desire to conform to this theology which we recived from our Lord through the apostles. We don’t join a club when we become Orthodox, we convert.
It is through this common Faith that we are one, so our desire is to conform. I don’t understand how that can work for so long unless with the assistance of the Holy Spirit. But the outward goal is to conserve and preserve the faith handed to us, neither adding nor subtracting.
… but I remember you saying this in another thread. It is the desire to be one along with God that holds the Orthodox together.
Which essentially means we desire to learn our received Faith, our common Faith, and learn how to worship together.
It makes one stubbornly conservative in religious matters, which I think becomes obvious from some of the discussions we have here.
But on that note, I’ve heard a rumor. Is it true that Orthodox church A can be in communion with church B but not C, and that C can be in communion with church B but not A?
It does sometimes happen.
In which case those are generally matters of discipline, and the breaking of communion hardly impacts the laity. It is more significant to the hierarchy who cannot concelebrate.
In fact it definitely happened in the early church in the east and the west. I know that Saint Ambrose of Milan excommunicateds some Spanish bishops (yet both he and they were in communion with the same other bishops in the church).
And if one reads the fragmentary history of the Great schism most athorities will agree that the break (between the Cardinals and the Patriarch at first, then the entire Roman church and the EP) did not happen all at once, it sort of fell apart over time and the process is hard to pin down in detail. So I am not sure when we can say that Antioch and Rome separated, the patriarch there apparently tried hard not to let the affair affect his church.
Each of the 15 or so churches is autonomous so does intercommunion between them ever hit trouble. I remember just a while back that the Church of Jerusalem broke communion with the Church of Romania because in essence one was building stuff on the other’d turf without permission. Are things like this a recurring problem or a fluke? Just wondering…
It is basically a fluke.
The Romanians could have had a ‘Representation’ parish if they received permission, but they didn’t get it, so they should not have built it.
That would be like the Archbishop of New York putting up a parish for Americans in Paris. It just isn’t done. The Jerusalem church has finally elevated it about as high as they can go, but in fact it has not caused a split in Orthodoxy, everyone else is in communion with both parties while they continue to dialog (or argue, as the case may be). As a practical matter nothing has really changed except the Romanian church and the Jerusalem church will not be concelebrating any liturgies any time soon, and their Primates will not be honored in one another’s dyptichs.
This is all about church discipline.
