Saint Benedict, father of western monasticism, is rather more known for his life and Rule than for a medal cast in his honor. The history of the image and the exorcism engraved on the medal, as well as the power of that Cross which the holy patriarch bears in his right hand, can be traced back to the eleventh century. Before he became Pope Saint Leo IX, one Bruno of Toul was cured of a mortal sickness after Saint Benedict appeared to him in the very guise we see depicted today on this sacramental. The Sisters of Charity under Saint Vincent de Paul also wore the blessed medal on their rosary. Abbot Gueranger, spiritual son of Saint Benedict, wrote this book to promote this very powerful devotion.
