The National Shrine is the beneficiary of two superior quality mosaics crafted at the Vatican Mosaic Studio. The Immaculate Conception is a copy of the famous oil painting by the Spanish artist Murillo. The image is a gift of Popes Benedict XV and Pius XI. It arrived in June 1930 and was initially venerated in the Crypt Church. It was relocated to its present position, outside the main sacristy, in 1963.
An Act of Consecration
Most Holy Trinity: Our Father in Heaven,
who chose Mary as the fairest of your daughters;
Holy Spirit, who chose Mary as your spouse;
God the Son, who chose Mary as your Mother;
in union with Mary, we adore your majesty
and acknowledge your supreme,
eternal dominion and authority.
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 of 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 innocence of our children.
Grant the precious gift of many religious vocations. Through the intercession of our Mother,
have mercy on the sick, the poor, 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.
