I found this on Spirit Daily which doesn’t link here nearly often enough
This is an article entitled
Bl. John Paul’s former personal secretary, Stanislaw Card. Dziwisz, now Archbishop of Krakow, spoke of two times the late Pope got angry.
He also revealed the two occasions he saw John Paul II “really angry,” but with “good reason.”
“In Agrigento, [Sicily], he raised his voice against the mafia, and we were all a little scared,” he said.
“And the other occasion was during the Angelus, before the Iraq War, when he said with force: no to war, war doesn’t resolve anything. I have seen war. I know what war is.”
Off the top of my head I can think of a couple more occasions.
One was when he publicly reprimanded a priest in Nicaragua, even shaking his finger at him, for being disobedient.
Another time was during a trip to his native Poland after the fall of Communism. Poland was sliding towards materialism and not using well their newly-won freedom and the Pope really let them have it.
There is a third time that I heard about but cannot verify. I was told by a source that when the clerical sexual abuse crisis blew up in the USA, and various prelates were summoned to a meeting, the Pope hollered at people, speaking among other things of “betrayal”. But that is a rumor.
I have known some pretty cool-headed icy-veined prelates in my time. And I have seen them in their rare moments of anger. Far more than the habitually choleric, the habitually placid leave a real impression when they are riled.
Imagine what Our Lord was like in the moment he saw the sacrilegious market activities in the Temple. He would never have gone out of control in anger, of course. But I suspect that He left His closest disciples rather small and very quiet.
