Based on the Encyclical Letter of Pope Piuis XII declaring the Feast of the Queenship of Mary, October 11, 1954.

From the earliest ages of the Church, whether in time of triumph or more especially in time of crisis, Christians have addressed prayers of petition and hymns of praise and veneration to the Queen of Heaven. Never has the hope placed in the Mother of the Divine King wavered.

Four years ago We defined the dogma of the Assumption of the Blessed Virgin Mary into heaven where she is present in soul and body, reigning together with her only Son, among the Heavenly choirs of angels and Saints. And now that We may bring this year of Mary to a happy and beneficial conclusion, and in response to petitions which have come to Us from all over the world, We have decided to institute the liturgical Feast of the Blessed Virgin Mary, Queen.

In this matter We do not wish to propose a new truth to be believed by Christians, since the title and the arguments on which Mary's queenly dignity is based have already been clearly set forth. She of whom was born the Son of the Most High received privileges of grace above all other beings created by God. Early writers referred to Mary as "the Mother of the King," basing their stand on the words of St. Gabriel the archangel, who foretold that the Son of Mary would reign forever, and on the words of Elizabet who greeted her with reverence and called her "the Mother of my Lord." Burning with poetic inspiration, St. Ephrem referred to Mary as the "Majestic and Heavenly Maid, Lady, Queen."
