Saints: Holy. Virtuous. Violent.
Fr. Sibley's asking for examples of saints who opened cans of whup-ass. [Scroll down to "Behind-Kicking Saints" in the June 5 postings--permalinks on the fritz]
Sts. Gabriel Possenti and Louis de Montfort come immediately to mind. St. Gabriel for his handgun artistry and St. Louis for his cleaning out of a saloon full of hecklers who were disturbing his outdoor mass (check Fr. Sibley's archives for 4/28/03).
Feel free to join the fray.
