In your opinion, what will replace the dying patriarchate?
Whatever needs to. Constantinople is not the New Jerusalem, and His Kingdom is not of this world. Rome fell away, and so can New Rome. No one is exempt, least of all me, who has not even yet tasted His most precious Body and Blood. Pray for me.
However, I hope that a strong zeal and conviction for the Orthodox Catholic faith will return to the Ecumenical Patriarchate. It was an unfortunate series of events which led to the current situation, and it seems to me that Ecumenical Patriarchate would have been better off if it had retained its control over the Orthodox Church in the Hellenic Republic. I know things couldn't have happened this way, it's just unfortunate. He's a shepherd without a flock, unless he reinterprets the canons to put everyone in the "barbarian" lands under his immediate jurisdiction. Then he suddenly goes from being in charge of several thousand souls to millions.
