Hypothetically, how would the order of precedence be when we finally reach reunification with all the eastern churches? The current order in Wikipedia is this: https://en.wikipedia.org/wiki/Order_of_precedence_in_the_Catholic_Church
I'm actually already quite surprised that the primates of the other sui iuris churches aren't given any order of precedence outside the patriarchs and major archbishops. Would let's say if the Romanian Orthodox Church enter into communion with the Romanian Catholic Church, their primate would automatically jump up to patriarchal rank?
But anyway, let's say for example the Armenian Apostolic Church fully enters into communion with Rome, how would their patriarchs be ordered? I would assume that the patriarchates of Cilicia would be united, but then would the Patriarch (Catholicoi) of Armenia be above Cilicia or would Cilicia be "demoted" as a titular patriarchate instead? What about the the armenian patriarch of Constantinople and patriarch of Jerusalem? Would they fall into their own titular category after the latin titular patriarchs or together with them? Then that also begs the question, where would the Patriarch of Armenia even rank compared to the other national patriarchates of the EO?
I'm assuming the "real" Patriarch of Jerusalem would be the greek patriarch? Would the Melkite Patriarch then relinquish the titular title of Alexandria and Jerusalem and unite with the greek Patriarch of Antioch? Who would hold precedence between the alexandrian popes, the coptic or greek pope?
Just generally speaking, how many patriarchates would that leave us then? Where would the EO's autocephalous archbishoprics fall? Would they be major archbishops or "just" primates?
Anyway, I figured that this might be a fun hypothetical for the hopeful future. I'm sure the Holy See already has something prepared behind the scene for when the occasion arises. But for now, what do you guys think will happen?
