Fr. Carl Pieber, C.M. can be seen here saying the Mass at the Miraculous Medal Chapel in Paris where Our Lady first appeared to St. Catherine Laboure. He goes to say a Mass each year for the intentions of all those enrolled in Mary's Miraculous Medal Family.
The Medal of the Immaculate Conception, popularly known as the Miraculous Medal, is unique among all medals. It was given by the Blessed Virgin Mary herself! No wonder, then, that it wins such extraordinary graces for those who wear it and pray for Mary's intercession and help. Our Lady manifested the Medal to St. Catherine Labouré on November 27, 1830, in the motherhouse of the Daughters of Charity of St. Vincent de Paul and St. Louise de Marillac, in Paris. Catherine saw Our Lady standing on a globe, with dazzling rays of light streaming from her outstretched hands. Framing the figure was an inscription: "O Mary, conceived without sin, pray for us who have recourse to thee." Then Mary spoke to Catherine: "Have a medal struck upon this model. Those who wear it will receive great graces, especially if they wear it around the neck."
The vision then seemed to turn to show the reverse of the Medal: the letter M surmounted by a cross with a bar at its base; below this monogram, the Sacred Heart of Jesus crowned with thorns, and the Immaculate Heart of Mary pierced with a sword.
With approval of the Catholic Church, the first medals were made in 1832 and were distributed in Paris. Almost immediately the blessings that Mary had promised began to shower down on those who wore her medal, and soon all of France was clamoring for what the people referred to as the "Miraculous Medal." Use of the Medal spread from country to country and now blankets the world. Everywhere, the Medal is still drawing down from God blessings for body and soul.
As far as we know, the last photograph on the left reveals what the first Miraculous Medals might have looked like when they were made and distributed in the 1830's. This would be about two years after Our Lady manifested the Medal to St. Catherine Labouré on November 27, 1830, in the Apparition Chapel of the motherhouse of the Daughters of Charity in Paris.
