I believe that, some years ago, Rome gave the Byzantine Catholics permission to omit the filioque in their recitation of the Creed, but with the understanding that they must accept the Dogma. I’ve known quite a few Melkiteand Maronite priests, from the Lawrence, Massachusetts area, and can say that all of them were enthusiastic supporters of Bergoglio. I never got the impression that either of those traditions was a good alternative. And, they were all as “loose as ashes” in their celebrations of Divine Liturgy, though the Byzantine, even celebrated poorly, outdoes the best Novus ordo.
