From what I've heard, (and I've heard much), there are several possibilities regarding the fate of ROCOR administration if/when reunion happens.
The first thing that most people here (I mean this forum) apparently think is that our bishops will sign a sheet of paper & say "Your the boss now..." or something like that. Then in comes a swarm of "clergy" from "over there" to take over our churches and kick out our priests and begin corrupting all and sundry by their false messages of salvation.
Ain't gonna happen.
Administratively it will be impossible for the MP to run ROCOR parishes from Russia. Most parishes in the US (I do not know about South American, European or Australian parishes) are incorporated, and actually don't belong physically to the ROCOR Synod. Therefore, it is the parish's choice ultimately of who is the priest there, what is done with the actual church building, etc. The MP will have no say in matters of church property of incorporated parishes unless individual parishes let it. This is a big decision that would be taken on by parish councils, etc. Besides that it means, if a parish decides to leave on a whole, it can take the building with it.
The reunion will be more spiritual than anything else. ROCOR will just become a self-ruling portion of the Russian Church, just like Japan is now. There will be free exchanges of anything to do with church life (be it clergy, books, learning materials, supplies, etc) that is beneficial to both sides. Also property seized by authorities for the MP will be sorted out... do not think that has been swept under the rug. Also locations with both MP & ROCOR will be working together to build a stronger Orthodox community.
Quite honestly, (and I say this while being a loyal ROCORist), if the MP was an evil opportunist, what the heck could it want ROCOR for??? We're such a pain to deal with, first of all. 2nd, yes, we do have some icons & relics that are highly prized, but they've got loads more. Our properties? We've already seen that in other countries, they don't our permission to snatch it. Besides that, with the amount of $ they have coming in, they could probably buy up twice the amount of property, and build bigger churches. Do they need us to obtain visas? Not anymore... if they are truly agents, there are easier avenues to get here than through us. Do they want money from us? Take into account how many people from ROCOR are already spending their hard earned dollars, pesos, euros whatever on MP products. Think of how many ROCOR parishes already send $ over there to help rebuild churches, feed & cloth & house the needy, etc etc. Do they need to feel validated, acknowledged by us to be sure that everyone accepts that they are a real church? They’ve already got a bunch of patriarchs outside their borders acknowledging them, do you really think they need a nod from 93rd St. in NYC to be seen as legit? If they want to control us somehow? To what end for goodness sake? To what purpose? To somehow turn us into their little minions? Get real. I think by now they would realize that we're to paranoid to ever let that happen.
