Biblical experience tells us that each time God calls, He asks for a response from the person and He sends that person to fulfill a mission. Recall Samuel, Jeremiah, Mary…

Zoé hears the call in her native village, Fain- les- Moutiers, and her response to God will be to enter the Company of the Daughters of Charity in Paris as a Postulant in 1829, and afterwards the Seminary at the Motherhouse, in April of 1830.

We know the mission God confided to Catherine, by way of Mary, through the apparitions of the Immaculate Virgin.

In this historic event we have the Commencement of the Marian Association.

This is the how Catherine explained this mission to her Director, Father Aladel, in her communication with him:

"The Blessed Virgin wishes to give you a mission …You will be the founder and director of a Confraternity of Children of Mary".

Another message given by the Blessed Virgin was that a medal should be made: the Miraculous Medal, which would be the insignia of the Association.

The integral message of the various Marian apparitions will have repercussions in her life and in the development and consolidation of the nascent group throughout its history.
