On the back of the medal is an initial and a drawing which introduce us to the secret of Mary.
The letter “M” is superimposed by the cross. The “M” is the initial of Mary; the cross is the cross of Christ. The two interlaced symbols represent the everlasting bond that ties Christ to his Holy Mother. Mary is associated with the mission of the salvation of humanity through her son Jesus, and by her compassion participates in the actual redemptive sacrifice of Christ.
At the bottom, two hearts, one surrounded by a crown of thorns, the other pierced by a sword.
The heart crowned with thorns is the Heart of Jesus. It reminds us of the cruel circumstances surrounding the Passion of Christ, recounted in the Gospels. It represents his Passion for His love of humanity. The heart pierced by a sword is the Heart of Mary, his Mother. It reminds us of the prophecy of Simeon recounted in the Gospels, the day of the Presentation of Jesus in the temple of Jerusalem by Mary and Joseph. It represents the love of Christ that dwells within Mary and his love for us: for our Salvation she accepts the sacrifice of her own Son.
The closeness of the two hearts expresses that the life of Mary is intimately tied to her son Jesus’ life.
Twelve stars are engraved around the medal.
They correspond to the twelve apostles and represent the Church. To be of the Church is to love Christ, and to participate in his Passion for the salvation of the world. Each person baptized is invited to become a part of the mission of Christ by uniting his heart with the hearts of Jesus and Mary. The medal is a call for each of us to walk the path of love completely, like Christ and Mary, to the point where we are totally giving of ourselves.
