ROCOR hasn't issued a decree on the Antiochians. And I'm not really saying anything now that I didn't believe before (members of the various fora know my position on the monophysite dialogue/union): I'm just using more explicit language to articulate my position now. I suppose it might appear to be bold.
CHRIST IS RISEN!
Justin (Paradosis), my brother, try to settle down. You don't find lifelong "cradle" Orthodox Christians, as a rule, taking to such extremist positions. No, it seems to be a characteristic of certain recent zealous converts to Holy Orthodoxy who become addicted to what Blessed Father Seraphim Rose called the error of the "Super-Orthodox." Without losing zeal, which is good (but not in and of itself), allow youself some time to rethink the matter. I do *not* favor false ecumenism myself, but I try--and it is difficult at times, I must admit--not to rush into rash judgment.
Where you see the EO priest communing OO's, and you are certain beyond the shadow of a doubt that this is happening, have you politely inquired of the priest why he is doing this? If you do not receive a satisfactory answer, then write politely to this priest's bishop and explain your concern and wait for the bishop to investigate--he may not even know this is occurring.
