The outward sign of belonging to the Congregation of the Sisters of Mary Immaculate is the medallion, which is called a “miraculous medallion” and is associated with the revelation of our Lady to St. Catherine Laboure (Paris 1830). Mary appeared to her as the Immaculate Conception, promising many graces to anyone who would turn to her for help. Saint. Catherine, with the permission of the Bishop of Paris, distributed medals to the faithful and enjoyed countless miracles, healings and granted requests of those who were wearing medallions with trust in intercession of Blessed Mary. They were soon called “miraculous medallions” and were spread throughout the world.
Around the figure of mother Mary, there is an inscription: “O Mary conceived without original sin, pray for us who fly to you”, which also became for our Founder an inseparable act of faith and veneration given to Mary. He left this prayer to us as a special inheritance and a sign of unity.
