I realize this is not the case for everyone. Some people in Eastern Catholic Churches can make the move to Orthodoxy and be very comfortable in doing so. I also feel this temptation from time to time (the temptation seems particularly strong on Sunday mornings when I am confronted with the fact that the Melkite parish is significantly farther away than the Antiochian Orthodox one!

). But I know that for me Orthodoxy is not a solution. Not only because no Church is perfect (though this is true – they all have their fights and scandals and problems to wrestle with), but even more because even as an Orthodox Christian I would still be caught in the middle. One would still be faced with a sense of longing and a sense of pain. Now we long for reunion with those who are admittedly our very near kin: Antioch. We long to see the Apostolic Church of Antioch be the vibrant and whole reality that it is capable of being. Should we leave communion with Rome, though, we will find ourselves longing, with a very similar sense of pain, for communion with our sister Church in Rome. To be Melkite is to be caught in this middle. This in fact was how the Melkite Church was born. Constantinople could not understand our longing for communion with our sister in Rome, was threatened and angered by it.
Following up on that thought, I would say that the communion of Catholic Churches appreciates that middle much better than Orthodoxy does at the moment. The uniqueness of our Churches is confirmed. There is a recognition that we have sacrificed something to be in communion with Rome. It is permissible and even a good that we long for communion with our family, that we feel close to them.
Within Orthodoxy there is an acknowledgement of the importance of Rome, but I think time and history have convinced the Orthodox that for now than get by without Rome. There is no urgency to the pain. There is even some suspicion of those who do express the desire for unity (and one need only think of the beating that the Ecumenical Patriarch regularly takes, especially from Moscow, for being a Papal stooge).
To be Melkite is to be in the middle. The Body of Christ is torn and broken, and we are the ones who mark the place where those wounds exist. For now this is what our Church does.
Finally, I would just say that the Latins you meet on a forum like this are not the typical person in the pew, nor are they very representative of the people in Rome who have made the East their lifelong concern. Quite honestly we have never been more respected by the Latin Church than we have been since Vatican2. Of course Rome is learning and still trying to figure out how deal with the non-Latin world…to find its place in the Body of Christ. And, the people in the pews barely even know we exist. Do not the occasional rabid and nostalgic Latin should not discourage you or even really bother you. (And when they do, remember that there are plenty of rabid and nostalgic Orthodox out there as well). The typical Roman Catholic you meet, as you probably well know, is much more curious than anything else to find out what it is we do and believe.
Salaam al-Maseeh.
