Catherine Labouré stated that on July 18, 1830, the eve of the feast of Saint
Vincent de Paul, she woke up after hearing the voice of a child calling her and leading her to the chapel of her convent. There, the Virgin Mary appeared to her and said: "God wishes to charge you with a mission...You will be contradicted, but do not fear, you will have grace...Tell your spiritual director all that passes within you...Times are evil. Sorrows will come upon France...The whole world will be upset by miseries of every kind...". that shone rays of light over the globe. Reportedly, Mary said to her that the rays symbolize the graces she is "shedding upon those who ask for them", and that the gems which did not shed light "are the graces for which souls forget to ask". As Catherine watched, the frame seemed to rotate, showing a circle of twelve stars, a large letter 'M' surmounted by a cross, and the stylized
Sacred Heart of Jesus crowned with thorns and the
Immaculate Heart of Mary pierced with a sword. Catherine heard the Virgin Mary ask her to "have a Medal struck after this model" and to take these images to her
confessor, and that "All who wear them will receive great graces...". Catherine did so, and after two years of investigation and observation of her ordinary daily behavior, her
priest took the information to the
archbishop of Paris,
Hyacinthe-Louis de Quélen, without revealing Catherine's identity. The request was approved and medallions were designed and produced through the goldsmith Adrien Vachette. The first 1,500 medals, originally called the "Medal of the
Immaculate Conception",
The chapel in which Catherine experienced her visions is located at the mother house of the
Daughters of Charity of Saint Vincent de Paul in
rue du Bac, Paris. The
incorrupt bodies of Saint Catherine Labouré and Saint
Louise de Marillac, a co-founder of the
Congregation of the Daughters of Charity of Saint Vincent de Paul, are interred in the chapel. == Properties of the medal ==
