As a young sister in her convent in Paris, Catherine had a vision of the Blessed Mother. Mary showed her the Miraculous Medal and told her to have it made. Catherine had to convince a lot of people in order to carry out the Blessed Mother’s request. Eventually her superiors, confessor, and the archbishop approved and the medal was made. Afterwards Catherine went back to her hidden quiet life. She took care of the convent chickens, answered the door, and was ready to do whatever was asked of her.
