why?
shouldn't the church of. Jerusalem, since you argue, Peter. is not the apostle to ge tiles. but Jews? Roman empire is ge tile, not Jewish, and Jerusalem is part. of the Easter Roman empire, not the west.
The RCC argument for preimenence makes zero sense, and even if that argument was to be accepted, then Moscow is the head of the Roman empire church, not Rome. Rome has not been the seat of the Roman empire since the 300s
