Orthodox ping!
It is seldom, no, never fruitful to quote the Latin polemicist Likudis to Orthodox Christians.
As a Greek Orthodox Christian, the Ravenna Document clearly states our position. That the Russians think otherwise is no surprise. Perhaps the matter will be cleared up and consensus found at the upcoming Great and Holy Council where I am sure the Pope will be ably represented.
As an aside, it is ironic that the thoroughly legalistic Russians would be opposed to some efforts at a reunion of the Churches. Their phronema, or mindset, is so much more Western than that of the Greeks and the Arabs and some of the Slavs one would think they would like the idea.
