I hope the Vatican’s official comments have made clear that the Pope is entitled to bend the rubrics, but that this effects no change in the duties of all other priests.
In the Novus Ordo, for many years, it was incorrect, at the “Ecce Agnus Dei,” for the priest to hold the Host over the chalice (rather than the paten), as in the Old Mass. (It is now okay.) JPII did this at least a few times when celebrating an N.O. Mass. Even if he did it by mistake, it was correct, because he was Pope. The liturgy is whatever the Pope chooses to do or happens to be doing.
“I hope the Vatican’s official comments have made clear that the Pope is entitled to bend the rubrics, but that this effects no change in the duties of all other priests.”
You’ve got to be kidding. In other words, do what the Church says, not what I do.
