Today we are especially invited to make a personal act of consecration to the Immaculate Heart of Mary, in unity with the Pope, so I thought I would provide a form of that consecration for your use.
Now I know some traditionalists have issues with the various papal initiatives (and lack thereof) on this subject, but a personal act of consecration at least should surely be encouraged!
Pope Francis and the bishops lead...
Pope Francis will officially re-consecrate the world to the Immaculate Heart of Mary today (October 13), on the ninety-sixth anniversary of the last apparition at Fatima.
The Vatican News Story on this notes that:
"Our Lady of Fatima appeared to three shepherd children in the village of Fatima in Portugal in 1917. She warned of violent trials in the twentieth century if the world did not make reparation for sins. She urged prayer and devotion to the Immaculate Heart of Mary."
I can't find any reference to this as yet on official websites, but according to a parish bulletin I picked up, the Australian Bishops have "elected to unite themselves in the spirit and intention of this great act of devotion to the Immaculate Heart of Mary. Accordingly, parishes and individuals are invited to make an act of consecration today.
There seem to be a large number of consecration to the Immaculate Heart prayers around the web, and apparently any formula that involves a total oblation is acceptable. But this one was written by Pope Pius XII, who made the first consecration of the world to the Immaculate Heart in 1942, to good effect:
"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."
I'm afraid I haven't been able to find a Latin version of this (if any one knows of it do let me know), so you will have to use the vernacular on this occasion!
