I happen to think sacrilege at Papal Masses have been a very common thing.
Check out the canonization Mass of St. Juan Diego and the beatification Mass of Mother Theresa. Marini invents something new, each and every time.
"Mischief is my name, novelty is my game."
I don't know about 'sacrilege' at Papal Masses--but I can tell you, regards Marini, that even a stopped clock is right twice a day.
B-16 is a far different "report" than was JPII. You can expect Marini to conform--he's not stupid.
