Life

The Dutch Jesuit who almost single-handedly held the German lands for the Church — forty years of preaching from Vienna to Fribourg, founding colleges, attending Trent, and writing the catechism that went through two hundred editions in his lifetime. He assured the overburdened that with God’s help they would find time to do it all.
