Since we are convinced, after long and serious reflection, that great good will accrue to the Church if this solidly established truth shines forth more clearly to all, like a luminous lamp raised aloft, by Our Apostolic authority We decree and establish the feast of Mary’s Queenship, which is to be celebrated every year in the whole world on the 31st of May. We likewise ordain that on the same day the consecration of the human race to the Immaculate Heart of the Blessed Virgin Mary be renewed, cherishing the hope that through such consecration a new era may begin, joyous in Christian peace and in the triumph of religion.

Let all, therefore, try to approach with greater trust the throne of grace and mercy of our Queen and Mother, and beg for strength in adversity, light in darkness, consolation in sorrow; above all let them strive to free themselves from the slavery of sin and offer an unceasing homage, filled with filial loyalty, to their Queenly Mother. Let her churches be thronged by the faithful, her feast-days honored; may the beads of the Rosary be in the hands of all; may Christians gather, in small numbers and large, to sing her praises in churches, in homes, in hospitals, in prisons. May Mary’s name be held in highest reverence, a name sweeter than honey and more precious than jewels; may none utter blasphemous words, the sign of a defiled soul, against that name graced with such dignity and revered for its motherly goodness; let no one be so bold as to speak a syllable which lacks the respect due to her name.

All, according to their state, should strive to bring alive the wondrous virtues of our heavenly Queen and most loving Mother through constant effort of mind and manner. Thus will it come about that all Christians, in honoring and imitating their sublime Queen and Mother, will realize they are truly brothers, and with all envy and avarice thrust aside, will promote love among classes, respect the rights of the weak, cherish peace. No one should think himself a son of Mary, worthy of being received under her powerful protection, unless, like her, he is just, gentle and pure, and shows a sincere desire for true brotherhood, not harming or injuring but rather helping and comforting others.

— Pope Piux XII,
declaring the Feast of the Queenship of Mary, October 11, 1954
