You are absolutely right! Perhaps you can now educate the Catholics on this matter ;-)
While I understand this comes from the Roman Catholic Church, I'm not sure the Orthodox would agree with this. They certainly don't agree with the filique in the Nicene Creed. They don't agree with some of the doctrines about Mary produced by the Roman Catholic Church and they certainly don't agree with the infallibility of the Pope. So how can the Pope be the final word?
The two churches were once one. Their division occurred nearly 1,000 years ago. The painstaking process of restoring unity is not something that can be accomplished overnight. However, progress is being made in that understanding.
From a 2007 Catholic News Service article:
Orthodox and Roman Catholics recognize that the bishop of Rome has primacy among all the world's bishops, although they disagree on the extent to which his leadership translates into a concrete exercise of authority.
Why should there be any "progress" if the matter is based upon tradition? This wouldn't be something new but something that people would look back on with a clear trail.
On another point, from the article...
