November 27 is the feast of the miraculous medal. The miraculous medal (French: Médaille miraculeuse), also known as the Medal of the Immaculate Conception, is a medal, the design of which was originated by Saint Catherine Labouré following her vision of the Blessed Virgin Mary and made by goldsmith Adrien Vachette. November 27 marks the anniversary of the Medal of the Immaculate Conception, known as the Miraculous Medal. This aided the Church's official declaration of the dogma in 1854. On the front is written: "O Mary, conceived without sin, pray for us who have recourse to thee." On the reverse, twelve stars surround a large "M," from which a cross arises. Below the "M," the medal depicts two flaming hearts.
The left heart, circled with thorns, represents Jesus. The right heart, pierced by a sword, symbolizes Mary. A 24-year-old novice, received the visions, in the community of Sisters known as the Daughters of Charity, Paris, France, in 1830. On July 18, 1830, a child awakened Sister Catherine Laboure. The child lead her to the convent's chapel where the Virgin Mary was sitting in a chair. She kneels beside Mary. A little more than four months later, during her evening meditation on Nov. 27, 1830, Catherine had a vision of Mary. Mary said, "Have a medal struck upon this model. Those who wear it will receive great graces, especially if they wear it around their neck."
