“This seems like an invitation for trouble.”
I doubt it. In any event it won’t have any Vatican II effects. In Orthodoxy, NOTHING a council (even an ecumenical one) says or does becomes dogma (or even a binding discipline) absent the Great Axios of the People of God, the Laity. We are the guardians of Orthodoxy, not the crowned heads!
Were that not enough, without the presence of Rome it can’t be an ecumenical council capable of defining dogma.
In general I agree with your comment. However...
“Were that not enough, without the presence of Rome it can’t be an ecumenical council capable of defining dogma.”
...is doubtful. There is a lot of divergent opinion in Orthodoxy on that subject. I have heard it said we can’t have an ecumenical council without an emperor to convene it. But with the Papacy in schism (and almost certainly heresy) the prerogatives of Old Rome have passed to the See of St. Andrew per the canons of the Fourth Ecumenical Council. It is worth remembering that we have held two great Councils that are universally accepted by the Church but not by Rome (three if we include the Qunisext Council).
