“The devotion to the Immaculate Heart of Mary is the means of salvation for these difficult times in the Church and in the world.”1 – Sr. Lucia, seer of Fatima Apparitions
On February 11, 1950, Pope Pius XII wrote:
“Christ is the way; Mary reflects the way; her Scapular is our keepsake on the way.”
“Therefore all Carmelites [including those who wear the Brown Scapular], … belong to the same Family of Our Most Blessed Mother and are attached to it by a special bond of love. May they all see in this Keepsake of the Virgin herself a Mirror of humility and purity; may they read in the very simplicity of the Garment a concise lesson in modesty and simplicity; above all, may they behold in this same Garment, which they wear day and night, the eloquently expressive symbol of their prayers for the divine assistance; finally, may it be to them a Sign of their Consecration to the Most Sacred heart of the Immaculate Virgin, a consecration which in recent times We have so strongly recommended.” Pope Pius XII, February 11, 1950
This website has information about making a personal consecration to the Immaculate Heart of Mary using three different methods: 33 Days to Morning Glory, St. Louis de Montfort, and St. Maximilian Kolbe.
