The Meaning of the Front Side of the Miraculous Medal
Mary is standing upon a globe, crushing the head of a serpent beneath her foot. She stands upon the globe, as the Queen of Heaven and Earth. Her feet crush the serpent to proclaim Satan and all his followers are helpless before her (Gn 3:15). The year of 1830 on the Miraculous Medal is the year the Blessed Mother gave the design of the Miraculous Medal to Saint Catherine Labouré. The reference to Mary conceived without sin supports the dogma of the Immaculate Conception of Mary—not to be confused with the virgin birth of Jesus, and referring to Mary's sinlessness, “full of grace” and “blessed among women” (Luke 1:28)—that was proclaimed 24 years later in 1854.

The Meaning of the Back Side of the Miraculous Medal
The twelve stars can refer to the Apostles, who represent the entire Church as it surrounds Mary. They also recall the vision of Saint John, writer of the Book of Revelation (12:1), in which “a great sign appeared in heaven, a woman clothed with the sun, and the moon under her feet, and on her head a crown of 12 stars.” The cross can symbolize Christ and our redemption, with the bar under the cross a sign of the earth. The “M” stands for Mary, and the interleaving of her initial and the cross shows Mary’s close involvement with Jesus and our world. In this, we see Mary’s part in our salvation and her role as mother of the Church. The two hearts represent the love of Jesus and Mary for us. (See also Lk 2:35).

Testimonial:
My father received a Miraculous Medal from my aunt who was a Daughter of Charity, to help protect him while driving. He was a police officer in a large city. At the request of my aunt, he kept his medal on his key chain. One day, he was in a shootout while on duty. A bullet struck his keys and deflected away from his femoral artery. He probably would have bled to death if the bullet had struck his artery. He ended up walking away from the shooting. He still has that Miraculous Medal.
