The faithful, under the guidance of an unerring Catholic instinct, have ever recognized the queenly dignity of the Mother of “The King of kings and Lord of lords.” The Fathers, the Doctors of the Church and Popes, down the centuries, have given authoritative expression to this truth and the crowning testimony to this common belief is to be found clearly expressed in the wonders of art and in the profound teaching of the liturgy. In their turn theologians have shown the fitting nature of this title of Queen as applied to the Mother of God, since she was so closely associated with the redemptive work of her Son and is the Mediatrix of all graces. Pius XII, by his encyclical letter of October 11, 1954, granted the unanimous desire of the faithful and their pastors and instituted the feast of the Queenship of Mary, giving sanction thus to a devotion that was already paid by the faithful throughout the world to the sovereign Mother of heaven and earth.
