^Father, to be honest, Archbishop Zoghby seems more consistent than you give him credit for. He explicitly stated he is completely in agreement with the Eastern Orthodox in everything (including so far as to say papal primacy is only in honor). Unless he was lying, there would be no doctrinal difference between us and his position.
If such were true of the Melkite Church itself, what would there be to work out? If they did completely agree with us on everything doctrinally, and communion is only possible with unity of belief, then what would be wrong with communing with them? Even if we don't care for their communion with Rome, so long as they do retain Orthodoxy (again, assuming such is the case like Archbishop Zoghby himself professed), I don't think that's enough to completely dismiss them.
Note: I am speaking of Antiochians and Melkites only, not necessarily all EO and definitely not all RCs.
