I'm sorry, but I can't celebrate Rome's continued ineptness in dealing with Eastern Catholics.
How can the Eastern Orthodox, Oriental Orthodox, etc. interpret the head of a sui juris Church in communion with Rome *kneeling* before the Pope and having *another* omophorion placed on him but as a act of submission?
The better question is, does Rome think the Ecumenical Patriarch, the Patriarch of Moscow, the Pope of Alexandria, etc. would find these sorts of actions acceptable? If the answer is no, Rome should immediately cease them in respect of the dignity of the Eastern Churches and their traditions (as Rome herself has said should be the case). If Rome answers yes, we have bigger problems. (I really think it would be a simple process for Rome to ask this question every time an action concerning the East is contemplated.)
The Eastern Catholic bishops should politely, but firmly decline any and all such gestures and structures that suggest a subservient status to the Bishop of Rome.
That being said, I think the act of requesting and giving the pallium to be a beautiful tradition as a sign of communion, but it cannot be done in any way that might even suggest that they derive their authority from the Pope.
