Canon 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.

§1. Ut veritatum fidei morumque integritas servetur, officium et ius est Ecclesiae pastoribus invigilandi, ne scriptis aut usu instrumentorum communicationis socialis christifidelium fidei aut moribus detrimentum afferatur; item exigendi, ut quae scripta fidem moresve tangant a christifidelibus edenda suo iudicio subiciantur; necnon reprobandi scripta quae rectae fidei aut bonis moribus noceant.

§2. Officium et ius, de quibus in §1, competunt Episcopis, tum singulis tum in conciliis particularibus vel Episcoporum conferentiis adunatis quoad christifideles suae curae commissos, supremae autem Ecclesiae auctoritati quoad universum Dei populum.
