Good question!
The Vatican has yet to make any concessions to the Orthodox (removal of the Filioque etc.) save for the concession on agreeing with Orthodoxy on the historic Unia of Brest and in trying to keep the UGCC in check, and also by denying it recognition of its patriarchate. Pope Benedict XVI recently went on record as telling an Orthodox representative that “we have inherited” the EC situation and the like. As close to an apology for the Unia as can be.
This truly is an internal matter of the RC Church - the traditional wing of the Latin Church, of which Pope Benedict is a member, is simply trying to gather up its allies to join in a common struggle. This is why traditionalist Anglicans and even Lutherans now have the Ordinariate model of church unity by which to reintegrate with Rome.
How Rome will get around the SSPX issues with Vatican II will be most interesting.
If it can, then perhaps this could be sent to the Congregation for the Causes of the Saints as a real miracle?
Alexander the Great is venerated as a prophet in Islam. Perhaps his cult in this regard can be extended to the Catholic Church and he could then become patron of Vatican ecumenism.
After all, “Big Al” did cut the Gordion Knot!
