The issue is not whether the Filioque can or cannot remain but why we can't get along better, if we can't agree that we all have the same Father and Jesus our savior.—Robert Helfman  I had an experience, once, visiting the sick in the hospital, the man may have been dying, but he recognized me as an apparent RCC priest.  An Orthodox priest also happened by and the man became furious with his dying breath, that the Orthodox priest should beat it.  The dying man was Uniate.  I knew enough Greek to gather that much.

The Faithful tend to miss the fact that Pope John XXIII called Vatican II ecumenical to attract the Orthodox, with considerably less concern for the impact of Vatican II on the RCC.  The Faithful are right to point to the Orthodox.  God bless you in this anticipatory Christmas Season.
