Attempts by theologians of both families aimed at overcoming the misunderstandings inherited from the past centuries of alienation towards one another have happily reached the same conclusion that fundamentally and essentially we on both sides have preserved the same Faith in our Lord Jesus Christ, in spite of diverse formulations and resulting controversies. On the Unity of the Faith- Joint Declaration of the Patriarchs of the Middle East
So Orthodox can disagree on if the Oriental Churches are "heretical" and still be in communion with one another. This of course contradicts Ecumenical Councils.
Which ones? There is no ecumenical council condemning the Coptic Church, the Armenian Church, etc., as heretical. Dioscorus was condemned at Chalcedon for convening a council unlawfully, not for heresy. I would of course agree that the Orthodox bishops describing the non-Chalcedonians as "fellow Orthodox" are misguided and engaging in wishful thinking, but doing so is far from a clear violation of the councils.
The Oriental churches were not, as a whole, condemned at Chalcedon; rather, it was the Oriental churches which chose to reject Chalcedon. I don't think it's possible to generalize about all of them, but the Copts certainly insist that there was no semantic misunderstanding. Regardless of what certain high-level joint statements may say, the Copts still consider Chalcedon to either have been Nestorian or to have been compromised by Nestorian tendencies. The only reason they
might be willing to enter communion with the Orthodox is that they believe we have since re-interpreted Chalcedon to mean something different. In other words, the Church did in fact lapse into Nestorian heresy but then corrected itself at the fifth ecumenical council. That, in my opinion, is an entirely unacceptable basis for union.
If you haven't already, I would recommend reading Pope Shenouda's
The Nature of Christ, available online. While it does not express monophysitism of the Eutychian sort, it is monothelite and monoenergist.
On a side note, for those Catholics who are considering uniting with
both the non-Chalcedonians and the Nestorians, I'm afraid you have a very tough road ahead. The Copts will absolutely not accept any union that does not uphold Ephesus and the theology of St. Cyril as the standard of orthodoxy. They will never accept union with a church that upholds Nestorius as a standard-bearer of orthodoxy. The following statement is worth reading:
http://www.lacopts.org/news/dialogu...s-effect-the-dialogue-the-roman-catholicBut Catholics of the East can't disagree with Rome on how certain Latin Dogmas (which we have shown are open for discussion as the Holy See has instructed) and practices relate to the East? We can't understand Papal Primacy or infallibility in different ways than our Roman brothers and sister? Or see Vatican I as a local council?
Erring as they may be, none of the Orthodox bishops would dare relegate Ephesus and Chalcedon to the level of "local council." None of the Orthodox bishops, as far as I know, has even hinted at repudiating these councils. As Fr. Ambrose pointed out, the joint statements tend to have a very nebulous character; this is necessary, because the theologies of the two communions are really not as close as many would like to think.
To me these issues are not black and white and there is a grey era. In my mind its nothing more than the Royal path of the Fathers.
I think the Royal Path of the Fathers was expressed very well in the ecumenical councils they gathered in. I don't presume to know better than the Fathers of the Church. As an Orthodox Christian, I believe in One, Holy, Catholic and Apostolic Church. The oneness of the Church is expressed visibly in communion and it is therefore impossible for two or more sections of the Church to be divided from one another for 1000 years or more. I was under the impression that the Catholic Church thought the same, but perhaps I was mistaken.
