Ορθοδοξία ή Θάνατος - Orthodoxy or Death — Μονή Εσφιγμένου - Esphigmenou Monastery.
Enemies, but not opposites, rather the mirror image of, the Orthodox counterpart to that tiny minority of Traditionalist Catholics who are Sedevacantist, both "'Catholic' Sedevacantists" and "opposed to 'world orthodoxy' Orthodox" are in full Communion with no one, and both appear to think that all holiness resides in, or at least with, themselves alone.
Confused? If you are not a specialist in this area of study, well you should be. Evil is attached to the sowing of confusion.
By way of the briefest of summaries, it may be said that:
- Old Catholics reject Pastor Aeternus, central to Vatican I, and Papal Infallibility in the pronouncement of binding doctrine on the Eternal Church by any pope on his own authority;
- Sedevacantist Catholics reject any inroads, real, symbolic or imagined, on the doctrine of Papal Infallibility, as also Vatican II and the legitimacy of all popes after Pius XII, regarding them as antipopes;
- Extremist Orthodox such as those at Esphigmenou Monastery essentially reject any dialogue with Catholics, as also with Oriental Orthodox to the limited extent that any of them even know who or want Oriental Orthodox are. With this they have come to reject their own leaders, the recent Ecumenical Patriarchs, Bartholomew of Constantinople and his predecessors Demetrios and Athenagoras. Of course they reject both Vatican I and and Vatican II. They reject as heretics all popes since the 1054 Great Schism at least, regarding them not as bishops. But even if future popes were to satisfy all their demands, such would enjoy only a primacy of honor. Popes would not bear the leadership of the Standing Apostolic Synod, as indeed such Orthodox see Apostle Saint Peter as either having had no successors, or alternatively they embrace an ecclesiology which holds that all bishops are successors of Peter and are so equally.
But the picture is vastly more complicated, as the latter two mentioned of these extremist groups,
Extremist Orthodox and Sedevacantist Catholics, are in fact right on many points.
Both are sometimes bulwarks against the Indifferentism with which "interfaith dialogue" is so very often conflated.
Both fail utterly to understand the vital distinction between on the one hand the holy re-unification of the Orthodox,
Oriental Orthodox and Catholic Churches back into the Orthodox Catholic Church, and on the other hand the unholy false unity
that constitutes most of the Ecumenical Movement, and worse still interfaith syncretism, e.g., "Judeo-Christendom" or "Chrislam".
And yet ignoring, or relegate to the secondary or still lower order of importance, that which is near the center
of God's explicitly expressed wishes is evil, as it is also itself a kind of heresy.
