Virgin Mother of God, Mary Immaculate,
I unite myself to you under your title of Our Lady of the Miraculous Medal.
May this medal be for me a sure sign of your motherly affection for me and a constant reminder of my filial duties toward you.
While wearing it, may I be blessed by your loving protection and preserved in the grace of your Son.
Mother powerful Virgin, Mother of our Savior,
Keep me close to you every moment of my life, so that like you I may live and act according to the teaching and example of your son.
Amen.
