Others are probably better suited to answer your question. Thus far, I think the work of the Joint Commission is one of those things that, while great, is being prayed over and thought about in both communions, but nothing concrete has been done on a wide scale. In certain places, it is allowed for members of one Church to commune at the other. I don't have a problem with this so much. In at least one instance (Antioch), it seems that the Orthodox Patriarch of Antioch and the Greek Patriarch in the same city allow for concelebration in some instances, which is something that I don't see a particularly urgent need for, and which I have mixed feelings about. Because I feel that EO and OO essentially believe the same things, it doesn't bother me on that level, but I still think it is premature for Orthodox hierarchs to sanction concelebration with the Greeks as in the Antiochian case. So a lot of work needs to be done, with a lot of sobriety and prayer, but I think it is a step in the right direction.
