The Feast of the Immaculate Heart of Mary falls on the Saturday after The Feast of the Sacred Heart of Jesus, which falls on the second Friday in June.

The following prayer is a prayer of consecration to the Immaculate Heart of Mary.

O Mary, Virgin most powerful and Mother of mercy, Queen of Heaven and Refuge of sinners, we consecrate ourselves to thine Immaculate Heart. We consecrate to thee our very being and our whole life; all that we have, all that we love, all that we are. To thee we give our bodies, our hearts, and our souls; to thee we give our homes, our families, our country. We desire that all that is in us and around us may belong to thee and may share in the benefits of thy motherly blessing.
And that this act of consecration may be truly fruitful and lasting, we renew this day at thy feet the promises of our Baptism and our First Holy Communion. We pledge ourselves to profess courageously and at all times the truths of our holy Faith, and to live as befits Catholics, who are submissive to all directions of the Pope and the bishops in communion with him. We pledge ourselves to keep the Commandments of God and His Church, in particular to keep holy the Lord’s Day. We likewise pledge ourselves to make the consoling practices of the Christian religion, and above all, Holy Communion, an important part of our lives, in so far as we shall be able to do.
Finally, we promise thee, O glorious Mother of God and loving Mother of men, to devote ourselves wholeheartedly to the spreading of devotion to thy Immaculate Heart, in order to hasten and assure, through the queenly rule of thy Immaculate Heart, the coming of the kingdom of the Sacred Heart of thy adorable Son, in our own hearts and in those of all men, in our country, and in all the world, as in Heaven, so on earth. Amen
