LOL! Now you made me laugh. :) As long as the Orthodox teach that there is no Immaculate Conception, no papal infallibility, no Purgatory, no "Original Sin" as Augustine defined it, etc. the Orthodox teach a different doctrine from the Latins. And that is, the definition, heresy. The Orthodox deny your dogmas and they are mere "schismatics?"
the Pope and the EP "committed to oblivion" in 1964. as regards excommunications of 1054, it merely returned the EP Ceruliarus and Cardinal Umbert back to the Church, making those excommunications null and void.
It doesn't change the fact that the two Churches differ on theological grounds as well as papal primacy of jurisdiction. What is different between protestants and Orthodox is that the latter is a sui juris Church and Protestant communities are Catholic fallouts. The Portetsants have only two options: remain outside the Church or return to the Latin fold. I think when it comes to reuniting with the Orthodox, the issue is moot, and the uniate approach is outright out of the question.
Yes they are.
The break with Rome was a schism. Absolutely a schism. Nothing more. An entirely different set of circumstances from the new theology of the Reformation. This was not a fundamental rupture over the very nature of what constitutes "church" or the sacraments. Heresy did not cause the break with Rome.
The Immaculate Conception issue did not cause the break with Rome neither did the quarrel over the nature of Purgatory. This was not a dispute over dogma. In fact in the case of the quarrels over purgatory, consecration by the words of institution, the procession of the Holy Ghost etc, there is really a misrepresentation of the the dogma to which the Orthodox object.
The relative integrity of the Orthodox churches in spite of their break with Rome does not in any way undermine the argument I made with respect to the Protestant churches for there is one fundamental difference between the two. The Orthodox still maintain access to the true sacraments of the Church while the Protestants do not. In that respect, the rupture with Rome is of an entirely different nature and of a drastically different severity to that which has occurred with the post-Reformation churches.
