Saint Catherine Labouré (1806)
Shortly after Labouré joined the Daughters of Charity, a religious order devoted to serving the poor, she reportedly began having visions of the Virgin Mary. In one, she was shown the design for what has come to be known as the Miraculous Medal, now worn by Christians the world over. Her role in the medal’s creation was concealed until after her death, so she lived out her life in relative obscurity. In 1947, she was canonized by the Roman Catholic Church. What invocation appears on the medal?
