Sister Lucia stressed the importance of consecrating yourselves and your families to the Immaculate Heart of Mary and to wear the Brown Scapular as a sign of consecration. Below is a prayer you can offer, and information on books to guide you spiritually in preparing for a total act of consecration to Jesus through Mary.
A Solemn Act of Consecration to the Immaculate Heart
Most Holy Virgin Mary, tender Mother of men, to fulfill the desires of the Sacred Heart of Jesus and the request of the Vicar of your Son on earth, we consecrate ourselves and our families to your Sorrowful and Immaculate Heart, O Queen of the Most Holy Rosary, and we recommend to you all the people of our country and all the world. Please accept our consecration, dearest Mother, and use us as you wish to accomplish your designs in the world.
O Sorrowful and Immaculate Heart of Mary, Queen of the Most Holy Rosary, and Queen of the World, rule over us, together with the Sacred Heart of Jesus Christ, Our King. Save us from the spreading flood of modern paganism; kindle in our hearts and homes the love of purity, the practice of a virtuous life, an ardent zeal for souls, and a desire to pray the Rosary more faithfully.
We come with confidence to you, O Throne of Grace and Mother of Fair Love. Inflame us with the same Divine Fire, which has inflamed your own Sorrowful and Immaculate Heart. Make our hearts and homes your shrine, and through us, make the Heart of Jesus, together with your rule, triumph in every heart and home. Amen.
— Venerable Pope Pius XII
