It is the late twelfth century and Christendom is threatened from within by the Albigensian heresy - a belief that the world is so evil that it must have been created by the devil. The consequences of this are more serious than one might at first think. Although they believe the man's soul was created by God (and therefore good), the Albigensians (who presumably "started out" as Catholics) reject the doctrine of the Real Presence because they believed the bread and wine were made by the devil, they didn't believe in marriage and having children and even went so far as justifying murder and suicide.

Enter Dominic de Guzman. Dominic decided to be a priest when he was very young. He understood the importance of all of his studies as preparation for his vocation. "A priest, or in fact any well-educated person, must learn all that he possibly can about all subjects He must learn not only those that are especially necessary for his chosen work." The story contains an excellent explanation of a good education and its purpose. "You must perfect yourself in arithmetic, algebra, geometry - the exact sciences, which will teach you to think clearly. You must learn to read with understanding...And, of course, logic. That will teach you to reason in a sound and exact way."

The story follows the life of St. Dominic as becomes a great preacher, continually arguing against the Albigensian heresy. He has limited success, however, until Our Lady appears to him and entrusts him with one of the greatest heavenly gifts - the Rosary.

This is an excellent story, well written and understandable, and filled with many important insights for us today.
