I think I have adequatley proved my point (thanks to EA's co-operation). There is no common ground between the Eastern Orthodox and the non-Chalcedonians. We do not share the same faith.
Polemics aside, I think it has been clearly shown we do
share the same Orthodox Faith, and that the Councils of the EO Church do not teach a dogmatically different faith, from OOy. The EO extra-councils are considered Orthodox (by mouth of HG Metropolitan Bishoy of the COC), and the OO tradition is considered Orthodox by mouth of the EO's who signed the Common Declarations. What we have therefore, is that the EO extra councils express the same christological dogma that we find in the OO tradition (most clearly in the teachings of the greatest christologist of the OOC St. Severus of Antioch), the EO's merely expressing it in a way traditional and peculiar to the Easterns. The OO's have a different tradition of expressing the very same dogmatic factum.
The schism resulting from various, complex, factors at Chalcedon is a schism that makes it necessary to supercede it in a truly pan-Orthodox council, at which the anathemas are lifted and a satisfactory solution is found that allows both expressions of the one Orthodox truth.
I do not accept your conclusions, they contradict the path opened up by the Holy Spirit as reflected in the Common Declarations. These are promptings of the Holy Spirit, and voices continuing separation, even for pious reasons, are (imho) ill-conceived. They originate from the passions, rather than passionlessness. Unless we learn to free ourselves from the passions, we will be ever deceived by them, and the walls of separation we have (sinfully) erected in the One, True, Church will continue to exist. These walls of (sinful) separation will cease to exist where the passions cease to exist. Reunion of the Church is therefore, first and foremost a work achieved in humility and repentance. For we are revolting against Christ, we fail to "discern His Body" spiritual sickness be the consequence (as happened in the community of the Corinthians, as we detect in St. Paul's writngs).
Still,.. due to our common dogmatic faith, common apostolicity, and common sacramentality, the union of our communities into the One, True, Church allready exists. The schism exists, solely, on the human level, and is the result, again solely, of our sins and weaknessess. The healing of the schism, is achieved, as I said above, by humility and repentance. Such is the only way for each of us to the Holy Altar for receiving union with Christ our God, and a restoration of intercommunion (on a limited and local level, as is practiced in the Orient already, as well as in the Russian Orthodox Church I attend) between us will ease the way for full, ecclesial, intercommunion to be ratified by a pan-Orthodox council.
Perhaps, and it is likely, you will strongly disagree, but such is my belief and for it I stand in the full consciousness of being loyal to my Church and its Lord Jesus Christ. But I agree, we can continue this discussion, without going anywhere beyond the point where we are now. Evidently, the unity of the Faith is still to be achieved for all of us, and we must continue to pray for it as we are encouraged to do in the prayer of Hours.
