Commissioned by Our Lord Himself to preach His Gospel, St. Vincent began at age 50 an apostolate of preaching that would extend to France, Italy, Spain, Belgium, Switzerland, Austria, Germany and a few other countries as well. Travelling with him were as many as 10,000 people, including at least 50 priests. The throngs that gathered to hear him came from many miles around, such that he was forced to preach in the open—no church being large enough to hold all the people. Impr. 205 pgs, 12 Illus.,
