O Mary Mother of Mercy and Refuge of Sinners! We beseech thee to look with pitying eyes on poor heretics and schismatics. Do thou, who art the Seat of Wisdom, enlighten the minds wretchedly enfolded in the darkness of ignorance and sin, that they may clearly recognize the Holy, Catholic, Roman Church to be the only true Church of Jesus Christ, outside of which neither sanctity nor salvation can be found.
Pope Pius XIIHenceforth it will be the task of this Sacred Congregation not only to examine carefully the books denounced to it, to prohibit them if necessary, and to grant permission for reading forbidden books, but also to supervise, ex officio, books that are being published, and to pass sentence on such as deserve to be prohibited.
Pope Pius XIIThat which does not correspond to the truth or to the moral norm possesses, objectively, no right either to existence or to propagation or to action.
Pope Pius XIIBut the knowledge and love of our Divine Redeemer, of which we were the object from the first moment of His Incarnation, exceed all that the human intellect can hope to grasp. For hardly was He conceived in the womb of the Mother of God, when He began to enjoy the Beatific Vision, and in that vision all the members of His Mystical Body were continually and unceasingly present to Him, and He embraced them with His redeeming love
