The Holy Father has declared a plenary indulgence for this day, which is also the patronal feast of the United States.
The following Act of Consecration was supposedly composed by Archbishop John Carroll, the first bishop of the United States (or Foederatarum Civitatum Americae Septentrionalis, to give it’s official Latin name).
Most Holy Trinity, we put the United States of America into the hands of Mary Immaculate in order that she may present the country to You. Through her we wish to thank You for the great resources of this land and for the freedom which has been its heritage. Through the intercession of Mary, have mercy on the Catholic Church in America. Grant us peace. Have mercy on our President and on all the officers of our government. Grant us a fruitful economy, born of justice and charity. Have mercy on capital and industry and labor. Protect the family life of the nation. Guard the precious gift of many religious vocations. Through the intercession of Our Mother, have mercy on the sick, the tempted, sinners – on all who are in need.
Mary, Immaculate Virgin, Our Mother, Patroness of our land, we praise you and honor you and give ourselves to you. Protect us from every harm. Pray for us, that acting always according to your will and the Will of your Divine Son, we may live and die pleasing to God. Amen.
