Can. 823 §1 In order to safeguard the integrity of faith and morals, pastors of the Church have the duty and the right to ensure that in writings or in the use of the means of social communication there should be no ill effect on the faith and morals of Christ’s faithful. They also have the duty and the right to demand that where writings of the faithful touch upon matters of faith and morals, these be submitted to their judgement. Moreover, they have the duty and the right to condemn writings which harm true faith or good morals.
§2 For Christ’s faithful entrusted to their care, the duty and the right mentioned in §1 belong to the Bishops, both as individuals and in particular councils or Episcopal Conferences; for the whole people of God, they belong to the supreme authority in the Church.
Can. 824 §1 Unless it is otherwise provided, the local Ordinary whose permission or approval for publishing a book is to be sought according to the canons of this title, is the author’s proper local Ordinary, or the Ordinary of the place in which the book is published.
§2 Unless the contrary is clear, what is said in the canons of this title about books, applies also to any writings intended for publication.

§3 It is recommended that books dealing with the subjects mentioned in §2, even though not used as basic textbooks, and any writings which specially concern religion or good morals, be submitted to the judgement of the local Ordinary.
§4 Books or other written material dealing with religion or morals may not be displayed, sold or given away in churches or oratories, unless they were published with the permission of the competent ecclesiastical authority or were subsequently approved by that authority.
