Papal Encyclicals, Apostolic Exhortations, Chirographs on Sacred Music, Infallible Statements…what does it all mean?
I have some definite opinions on things like the liturgy, and they tend to line up very stalwartly with the Pope’s opinions and those of Cardinal Arinze.
But between the aforementioned documents, which ones are REQUIRED to be believed and followed? For instance, the Pope has opined that guitars don’t belong in the Mass, but my understanding is that it is nowhere canonically forbidden.
What is the strength placed behind each of the aforementioned types of documents?
