Before going to her new destination, Sister Labouré passed some days in one of the large establishments of Paris. Wishing to examine the young Sister more leisurely, M. Aladel made a pretext of visiting the Sisters at this house. The account of these visions had already been circulated throughout the Community, and it was known that M. Aladel had received the Sisters' confidence; hence, as soon as he appeared, the Sisters surrounded him, and each one eagerly plied him with questions. He had his eye upon Sister Catherine, who, without being disconcerted, quietly mingled her inquiries with the others. The worthy missionary was reassured, understanding that the Sister kept her secret.

The last time the Blessed Virgin appeared to Sister Labouré in the sanctuary of the Mother House, she said to her: "My daughter, henceforth you will see me no more, but you will hear my voice during your meditations." And, indeed, during the whole course of her life, she had frequent communications of this kind. They were no longer sensible apparitions, but mental visions, that she well knew how to distinguish from the illusions of imagination or the impressions of a pious fervor.

Her mission had not been accomplished in regard to the medal. Some months elapsed, and the Immaculate Virgin complained to Sister Catherine that her orders had not been executed.

"But, my good Mother," replied Sister Catherine, "you see that he will not believe me." "Be calm," was the answer; "a day will come when he will do what I desire; he is my servant, and he would fear to displease me."

These words were soon verified.

When the pious missionary received this communication, he began to reflect seriously. "If Mary is displeased," said he, "it is not with the young Sister, whose position prevents her doing anything; it must be with me." This thought troubled him.[4] A long time previous, he had related these visions to M. Étienne, then Procurator General. One day, at the beginning of the year 1832, when they had gone together on a visit to Mgr. de Quélen, M. Aladel profited by the opportunity to speak to the latter of these apparitions, and especially of his own embarrassment, since the Blessed Virgin had complained to the Sister of the delay in fulfilling her commands.

Mgr. de Quélen replied that, seeing nothing in it at all contrary to faith, he had no objection to the medal being struck at once. He even asked them to send him some of the first.

The ravages of the cholera, which had broken out meanwhile, retarded the execution of this design until June; the 30th of that month, two thousand medals were struck, and M. Aladel hastened to send some of them to the Archbishop of Paris.

Mgr. de Quélen wished to make an immediate trial of its efficacy; he was very much troubled concerning the spiritual condition of the former Archbishop of Mechlin, Mgr. de Pradt, now on the verge of death; he desired his conversion so much the more earnestly, as the death of this prelate might be the occasion of scandal and grave disorders, such as have accompanied the interment of the constitutional bishop Gregory. Providing himself with a medal, he went to visit the sick man. At first he was refused admittance, but very soon the dying man repents of it, and sends him an apology, with a request to call again. In this interview, he testifies to His Grace a sincere repentance for his past life, retracts all his errors, and after receiving the Last Sacraments, he dies that very night in the arms of the Archbishop, who, filled with a holy joy, eagerly imparts this consoling news to M. Aladel.
