(The first two parts of this series covered the childhood of Catherine (“Zoe”) Laboure´, her entrance into the order of the Sisters of Charity, and her first visions. Part 3 describes the visions of the Blessed Virgin Mary that revealed her mission to bring the “Miraculous Medal” into existence.)
Part 3: The Miraculous Medal
By November of 1830, the unrest in Paris was over, and Louis Philippe had taken the throne. On Nov. 27, eve of the First Sunday of Advent, Catherine was in the chapel with the other sisters for evening meditation, when she again heard the swish of a silk dress. Looking up, she saw a vision of the Queen of Heaven dressed all in white, standing on a globe and holding a golden ball in her hands. Her fingers were covered with rings whose stones sparkled with brilliant light that poured from them all the way down to her feet. She was radiant “in all her perfect beauty,” as Catherine later described it. Catherine heard the words, “The ball which you see represents the whole world, especially France, and each person in particular. These rays symbolize the graces I shed upon those who ask for them. The gems from which rays do not fall are the graces for which souls forget to ask.”
Then the vision changed. The ball vanished, and Mary’s arms swept downward, the rays cascading to the globe on which she still stood, her foot crushing the head of a serpent. The globe had the year “1830” inscribed upon it. The Virgin wore a blue mantle over a white dress, with a white veil draped back over her shoulders. An oval formed around the vision like a frame, and written in gold letters within it were the words: “O Mary, conceived without sin, pray for us who have recourse to thee.”
The voice said, “Have a medal struck after this model. All who wear it will receive great graces; they should wear it around the neck….” The apparition reversed, and Catherine saw a large M surmounted by a bar and a cross, with the Hearts of Jesus and Mary beneath it, one crowned with thorns, the other pierced by a sword (symbolic of the prophecy of Simeon, when he told Mary, “a sword shall pierce your own heart, so that the thoughts of many hearts will be revealed.” Luke 2:35). Twelve stars encircled the whole thing. The vision then faded, but would be repeated five more times over the next year.
Catherine told Fr. Aladel about the latest apparitions and the request to have a medal struck. As with her other visions, he did not accord it much importance. Each time the vision was repeated, poor Catherine was compelled once again to approach Fr. Aladel about it. These were extremely unpleasant encounters for Catherine, often involving verbal battles between her and Fr. Aladel. The other Sisters would see Catherine approach the confessional trembling with fear, then hear the sound of raised voices issuing from within.
Although Catherine was never disobedient or rebellious, and would cease the discussion at Fr. Aladel’s order, she was not to be dissuaded from the mission she believed God had entrusted to her. While honoring her vow of obedience, she nonetheless possessed a strong will and a spirited tongue, and doggedly pursued her mission. There is no doubt that, as Our Lady had warned, Catherine suffered much during this period, even to the extent of telling the Virgin that she “had better appear to someone else, since no one will believe me.” Only Our Lady’s promise of God’s grace sustained Catherine and made it possible for her to persevere.
In fairness to Fr. Aladel, his was not an easy task, either. He needed to determine if Sister Catherine’s visions were genuine and whether it would be prudent to act on them. But eventually, as he came to know Catherine better, he realized that by her very nature it was unlikely that she was inventing it all. He knew that she was good and pious, and he did not doubt the sincerity of her belief that she had seen these things. He also realized that of herself she did not possess the intellectual ability nor the imagination to fabricate such a story with all its lavish detail. Then, too, was the fact that her reported prophecies had indeed come true. Furthermore, he had given his promise to Catherine early on that her identity not be revealed, which placed all the responsibility for carrying out heaven’s orders on his shoulders alone.
Meanwhile, the end of Catherine’s novitiate was fast approaching, when she could possibly be assigned to a far-away post. Somehow, Fr. Aladel managed to use his influence to ensure that Catherine was assigned to the Hospice d’Enghien at Reuilly, where he was the regular confessor. This, of course, was necessary because of his role as Catherine’s spiritual advisor in the matter of her visions. The Hospice had been founded as a retirement home for the old men who in earlier years had served the royal family. Sr. Catherine’s duty would now be to care for these aged residents.
Shortly after her arrival at Enghien, while visiting the chapel at the Motherhouse, Catherine saw Our Lady again. The apparition took the same form as it had on Nov. 27, but on this occasion Our Lady informed Catherine, “You will see me no more, but you will hear my voice in your prayers.” In the following weeks, during her prayers Catherine heard the frequent urging of Our Lady that the medal be struck. When Catherine complained that Fr. Aladel did not believe her, Our Lady replied, “Never mind. He is my servant and would fear to displease me.”
No doubt it was these words reported back to Fr. Aladel that finally spurred him to action. His love for Mary and his fear of angering her overcame the lingering doubts he had about Catherine’s visions. Indeed, Our Lady seemed to have great confidence in him, as he also would later be spiritual advisor to Sr. Justine Bisqueyburu, to whom the Green Scapular was manifested in 1840, and would be responsible for its production and distribution.
In January 1832, his good friend, Fr. Etienne, had an appointment with Archbishop de Quelen and asked Fr. Aladel to accompany him. After Fr. Etienne’s meeting, Fr. Aladel took this opportunity to tell the Archbishop about the visions and Our Lady’s request for a medal. After much careful questioning, the Archbishop, who was especially devoted to the Immaculate Conception, consented. On June 30, 1832, the first 2,000 Medals of the Immaculate Conception were delivered. Catherine, upon receiving her share of medals, said, “Now it must be propagated!” She was to keep a few of these first Medals until the end of her life (one of them can be seen at the Miraculous Medal Art Museum in Germantown, PA).
As the saying goes, the rest is history: The Medal’s rapid spread throughout France and the world, and its astonishing impact as a sacramental was rivaled only by the Rosary. So many healings, conversions, and wonders sprang from it that it soon became known as “the Miraculous Medal.”

Catherine’s great mission was accomplished; and the ecstasy of the heavenly visions, as well as the despair and frustration of trying to convince Fr. Aladel to act on them, was over. Now Catherine would embark on the final, and longest, phase of her earthly journey: the hidden life of obscurity as she settled into the ordinary routine that was to be her destiny for 46 years.
