Any subsequent Ecumenical Council is their equal.
And I didn't mean inject error--I meant change the words by which the dogmatic truth is expressed. Totally different.
A dogmatic pronouncement of an ecumenical council accepted by The Church is not a disciplinary matter nor are concilliar prohibitions of any change in dogma.
Remember we are talking here only about the canon that apparently (I don't believe it did, but I'll grant the argument) forbade any change in wording of the Creed. The concepts within the Creed are dogmatic and eternal. But regulations concerning how or when those concepts are put into words can be changed. See the difference? If the words themselves were dogmatic and the Creed could not be added to, then by what right did the Fathers of 381 dare to add to the words given them by the Fathers of Nicaea?
No offense guys, but you’re off topic.
The topic of the thread is regarding the relations with the Romanian Catholic Church and the Romanian Orthodox Church and inter-Communion. Not the Latin Church and the Orthodox Churches on the filioque.
As for the subject, I would suspect that the Hierarchy in Rome would consider this an internal Romanian issue.
