From the start of his pontificate, the Pope has used his Wednesday audiences to present the timeless wisdom that has been expressed in the writings and lives of holy men and women down through the ages. He began with the Apostles and then moved to the Fathers of the Church. Next he presented the great Christian teachers of the late Roman Empire and the early Middle Ages. In this volume, he picks up the thread in the high Middle Ages with the inspirational St. Francis and St. Dominic, followed by some of the men and women they profoundly influenced, such as Clare, Bonaventure, and Thomas Aquinas.
