Quite an encyclical, Marmema. Seems +BXIV disagrees with gbcdoj.
Don't forget that my former Melkite pastor delivered a sermon on the Feast of Sts. Peter and Paul denying the pope has universal jurisdiction by divine right.
Pope Benedict XVI would be doing a great service if he suppressed the filioque and declared Lyons II and Florence to have merely been general councils of the Western Church. BTW, Dominus Iesus includes the Creed without the Filioque.
