Are you endorsing this?
So, then, if anyone says that the Roman Pontiff has merely an office of supervision and guidance, and not the full and supreme power of jurisdiction over the whole Church, and this not only in matters of faith and morals, but also in those which concern the discipline and government of the Church dispersed throughout the whole world; or that he has only the principal part, but not the absolute fullness, of this supreme power; or that this power of his is not ordinary and immediate both over all and each of the Churches and over all and each of the pastors and faithful: let him be anathema. (First Vatican Council, First Dogmatic Constitution on the Church of Christ, III, 9)
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.
Dream on. How was Florence only a council of the "Western Church" when the Greeks were there and assented?
PS: Do we Latins get to demote the first seven councils to "general councils of the Eastern Church"?
Florence was agreed upon under duress and later was repudiated as a false council by the Eastern Churches.
To add Patriarch Gregory II's reservation: "Without prejudice to the rights, privileges and honor of the Eastern patriarchs."
