i wouldn’t call rocor separate from moscow. i would call them distinct from the oca.
(that’d be 2 ‘jurisdictions’ not 3 if that really amounts to a different jurisdiction)
i’d say it’s similar to how the uniate parishes function within the catholic church which isn’t considered to be multiple jurisdictions.
i’d kind of like to see the MP yank the OCA’s autocephally, and bring them into the same situation ROCOR is in. I’d also like to see concelebration between the OCA and ROCOR.
(noting that the mp and oca can concelebrate, and today rocor and the mp have concelebrated, so why not the oca and rocor??)
My usage of the term jurisdiction was in reference to episcopal jurisdiction, not patriarchal or autocephalous. As for the Eastern Rite Catholics, their separate episcopal jurisdictions are based either on rites or ethnic origins (as is the case with the multiple Orthodox jurisdiction in the West). With the ROCOR and OCA there will be the case of two different bishops ministering in the same territory to parishes of the same rite and same ethnic origin.
If Moscow and ROCOR are in Communion, that means that the OCA and ROCOR are in Communion as well.
Same goes for all the Canonical Orthodox Churches.
