my understanding is that the Pope lacks any such authority
The faithful Catholics turned their cheek and are willing to die for their Faith in God.
Per Vatican I:
If anyone thus speaks, that the Roman Pontiff has only the office of inspection or direction, but not the full and supreme power of jurisdiction over the universal Church, not only in things which pertain to faith and morals, but also in those which pertain to the discipline and government of the Church spread over the whole world; or, that he possesses only the more important parts, but not the whole plenitude of this supreme power; or that this power of his is not ordinary and immediate, or over the churches altogether and individually, and over the pastors and the faithful altogether and individually: let him be anathema.
