Dominic was born to noble parents in Caleruega, in the Kingdom of Castile, present-day Spain. An early biographer tells that his mother, struggling to conceive, made a pilgrimage to a local monastery where Saint Dominic of Silos had been abbot. At that time, she dreamt that a dog emerged from her womb and, with a torch, set the world on fire. “Dominic” is translated as “The Lord’s Dog.”
Today’s saint came from a holy family, excelled at his studies, and was devoted to the poor. When Dominic was twenty-four, Bishop Diego de Acebo of Osma ordained him as an Augustinian canon of the cathedral, hoping that he would help reform the other canons. For nine years, Father Dominic lived a life of deep prayer and witness, eventually becoming prior.
In 1203, Father Dominic accompanied Bishop Diego on a diplomatic mission for the King of Castile during which they discovered two grave needs in the Church. First, many northern Europeans had not heard the Gospel message. Second, a heretical group in southern France, the Cathars, were leading many astray. The Cathars followed a form of the Albigensian Heresy, which taught that there were two gods: one good, associated with the New Testament and the spiritual world, and one evil, associated with the Old Testament and the material world. They believed that people must escape the material world’s evil, achieved by a rigorously ascetic lifestyle. When Bishop Diego and Father Dominic detoured to Rome to consult with the pope, he sent them back to southern France to convert the Cathars. Father Dominic understood that the best way to combat the heresy was to form an order that lived in extreme asceticism yet remained true to the faith.
Living in poverty as itinerant preachers, Father Dominic and Bishop Diego engaged in public debates and private dialogues with the Cathars to point out their errors through reason and persuasion. After Bishop Diego died, Father Dominic founded a convent in Prouille in 1206 dedicated to Saint Mary Magdalene, believing that it was through prayer that souls would be saved. While providing a safe haven for women and nuns converted away from the Albigensian heresy, the convent educated girls in the true faith.
Miracles that God worked through Father Dominic resulted in conversion and new followers. In 1215, with the Bishop of Toulouse’s permission, Father Dominic founded an order of men dedicated to evangelization. They lived communally; prayed together; embraced poverty, obedience, and chastity; studied the faith; and went on preaching and evangelizing missions. The following year, Pope Honorius III gave formal consent to the Order of Preachers, also known as the Dominicans. In 1217, the pope gave Father Dominic the Church of Santa Sabina in Rome as the order’s second home and made Father Dominic the pope’s chief theological adviser. Still, Father Dominic slept on the floor, wore a hairshirt, and often walked barefoot when entering a new town.
In the years following until Dominic’s death in 1221, other houses were founded in Paris, Madrid, and Bologna. After his death, the order continued to expand. By the mid-1200s, hundreds of Dominican houses had sprung up across Europe and in other parts of the world.
