Mirabile Illud §10

¹⁰ You are undoubtedly aware that We shall celebrate the Eucharistic sacrifice at the hour of midnight that marks the beginning of the feast of the Immaculate Conception of the Blessed Virgin Mary, and that our suppliant voice by means of radio communication may be heard by all. We wish, moreover, that especially on that holy night all the faithful, united with the Vicar of Jesus Christ, should invoke from the Father of Mercies through the intercession of the most powerful patronage of the Virgin Mother of God, preserved from every stain of Original Sin, that at long last, with hatreds put to rest and all differences justly and equitably settled, the light of real and genuine peace may radiate to all nations and peoples.
