Regarding: " “...it is also clear for us as Catholics that loyalty to the pope is substantial for the Catholic faith.”"
- No doubt 'catholic' hear means those catholics who are in communion and union with the successor to Peter, the archbishop of Rome. There are a great many catholics who are in neither communion, or union.
- No doubt 'loyalty' means being attentive to the ArchborRome as the one with whom one is in union and communion.
- The relationship of communion and union allows for a great deal of dialog, discussion, and disagreement. In such a relationship the 'taught church' (body of christ)  effectively teaches the 'teaching church' (the successors of the apostles).
