10. The books of classical authors, whether ancient or modern, if disfigured with the same stain of indecency, are, on account of the elegance and beauty of their diction, permitted only to those who are justified on account of their duty or the function of teaching; but on no account may they be placed in the hands of, or taught to, boys or youths, unless carefully expurgated. V. OF CERTAIN SPECIAL KINDS OF BOOKS 11. Those books are condemned which are derogatory to Almighty God, or to the Blessed Virgin Mary or the Saints, or to the Catholic Church and her worship, or to the Sacraments, or to the Holy See. To the same condemnation are subject those works in which the idea of the inspiration of Holy Scripture is perverted, or its extension too narrowly limited. Those books, moreover, are prohibited which professedly revile the Ecclesiastical Hierarchy, or the clerical or religious state. 12. It is forbidden to publish, read, or keep books in which sorcery, divination, magic, the evocation of spirits, and other superstitions of this kind are taught or commended. 13. Books or other writings which narrate new apparitions, revelations, visions, prophecies, miracles, or which introduce new devotions, even under the pretext of being private ones, if published without the legitimate permission of ecclesiastical superiors, are prohibited. 14. Those books, moreover, are prohibited which defend as lawful duelling, suicide, or divorce; which treat of Freemasonry, or other societies of the kind, teaching them to be useful; and not injurious to the Church and to Society; and those which defend errors proscribed by the Apostolic See. VI. OF SACRED PICTURES AND INDULGENCES 15. Pictures, in any style of printing, of our Lord Jesus Christ, the Blessed Virgin Mary, the Angels and Saints, or other Servants of God, which are not conformable to the sense and decrees of the Church, are entirely forbidden. New pictures, whether produced with or without prayers annexed, may not be published without permission of ecclesiastical authority. 16. It is forbidden to all to give publicity in any way to apocryphal indulgences, and to such as have been proscribed or revoked by the Apostolic See. Those which have already been published must be withdrawn from the hands of the faithful. 17. No books of indulgences, or compendiums, pamphlets, leaflets, etc., containing grants of indulgences, may be published without permission of competent authority. VII. OF LITURGICAL BOOKS AND PRAYER BOOKS 18. In authentic editions of the Missal, Breviary, Ritual, Ceremonial of Bishops, Roman Pontifical, and other liturgical books approved by the Holy Apostolic See, no one shall presume to make any change whatsoever; otherwise such new editions are prohibited.
