I concede  that if Pope Francis changes Church Law to stop the cover-ups of clergy pedophilia then that would be easier than getting 196 countries to agree on something.

However, countries that oppose to change their criminal laws could be named and shamed for allowing cover-ups of clergy pedophilia.

Besides, I see a zero chance of the Curia (who, in my opinion, is the real boss at the Vatican) agreeing to change the sections of Church Law that allow the concealment of child sexual abuse by priests.

It seems obvious that the Curia will wait until nearly all the current Bishops and Cardinals are dead (that means until around 2040) to once more offer apologies and hope that this issue will be almost forgotten by then.
