"Following the inspiration of the founder, Father Joaquin Masmitja, the Sisters take as their model and protectress the Blessed Virgin Mary, turning to her in all things to beg her maternal protection and the guidance as they seek to imitate the life of her Son" (IHM Constitutions, #4). At all times and in all circumstances the Sisters endeavor to be living images of our Lady, the Mother of God, who continually points to her divine Son.

Our Lady's "fiat" at the Annuciation: "Let it be done unto me accordingto thy Word" becomes the profession of each IHM as she strives to live their motto: "I take what is set before me." Each Sister reflects upon Mary's "yes" making it her own.

As Mary spent her life pondering the mysteries surrounding the life of her Son, each Sister meditates upon the life of Jesus, reflecting on it in her own heart.

Mary at the foot of the Cross completes her "fiat" as she accepts all of the sufferings Christ undertook for the redemption of the world; taking Mary as their model the Sisters participate in these mysteries throughout their own lives for the conversion of sinners and the sanctification of priests.
