"The more a soul is consecrated to Mary, the more it is consecrated to Jesus Christ"

"If you put all the love of all the mothers into one heart it still would not equal the love of the Heart of Mary for her children."         St. Louis de Monfort

A Solemn Act of Consecration to the Immaculate Heart of Mary

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.

There are many different formulas of consecration to the Immaculate Heart of Mary. This website lists and declaims most of them. The one above is the Pope Pius XII consecration formula.

I like this act of consecration of all the others I have prayed, simply because I grew up praying this daily with my family.
