Here's a Vatican bigwig during the Reformation who didn't light anyone on fire, nor did he grow rich, fat, and lazy on the blood, sweat, and tears of the exploited working class. That alone sounds miraculous enough to earn sainthood, but then consider that he held about a dozen titles (archbishop of this, cardina-protector of that, administrator, papal legate, etc) and took them all seriously. He reorganized the church (starting with calling the rich, fat, lazy clerics in Milan to task for neglecting their flocks) of Milan, and then survived an assassination attempt by a hitman hired by some Milanese clergy. He fed 3000 people with the wealth of his diocese during a famine. And he organized the care of the sick and burial of the dead during a famine.
It is good to know that even at a low point in the history of the western church, there were good folks like St. Charles who took seriously the charge to care for their flocks.
