The Medal of the Immaculate Ception, commonly called the Her feet rested on a white globe...I saw rings on her fingers...Each ring was set with gems...The larger gems emitted greater rays and the smaller gems smaller rays.
Catherine heard an interior voice: 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 forgot to ask.
An oval flame formed around the Blessed Virgin, and within it in letters of gold Catherine read the words: O Mary Conceived Without Sin, Pray For Us Who Have Recourse To You.
The voice spoke again: Have a Medal struck after this model. All who wear it will receive graet graces; they should wear it around the neck. Graces will abound for persons who wear it with confidence.
Catherine continued: The tableau seemed to turn, and I beheld the reverse of the Medal: a large M surmounted by a bar and a cross; beneath the M were the Hearts of Jesus and Mary, the one crowned with thorns, the other pierced with a sword.
The front of the Medal represents Mary standing on the earth, her foot crushing the head of a serpent, and her hands outstretched to all who ask her assistance. The prayer encircling her contains one of her most precious titles: O MARY CONCEIVED WIYHOUT SIN, PRAY FOR US WHO HAVE RECOURSED TO YOU. The rays of light from her hands symbolize the graces which she is only too eager to bestow upon those who wear the Medal and pray to her.
The Medal was made according to Our Lady's design. It was freely circulated and in a short time was worn by millions. In its wake followed innumerable wonders. Health was restored, sickness banished, blessing bestowed.
