2. The books of apostates, heretics, schismatics, and all writers whatsoever, defending heresy or schism, or in any way attacking the foundations of religion, are altogether prohibited. 3. Moreover, the books of non-Catholics, _ex professo_ treating of religion, are prohibited, unless they clearly contain nothing contrary to Catholic Faith. 4. The books of the above-mentioned writers, not treating _ex professo_ of religion, but only touching incidentally upon the truths of Faith, are not to be considered as prohibited by ecclesiastical law, unless proscribed by special decree. II. OF EDITIONS OF THE ORIGINAL TEXT OF HOLY SCRIPTURE AND OF VERSIONS NOT IN THE VERNACULAR 5. Editions of the original text and of the ancient Catholic versions of Holy Scripture, as well as those of the Eastern Church, if published by non-Catholics, even though apparently edited in a faithful and complete manner, are allowed only to those engaged in theological and biblical studies, provided also that the dogmas of Catholic Faith are not impugned in the prolegomena or annotations. 6. In the same manner, and under the same conditions, other versions of the Holy Bible, whether in Latin, or in any other dead language, published by non-Catholics, are permitted. III. OF VERNACULAR VERSIONS OF HOLY SCRIPTURE 7. As it has been clearly shown by experience that, if the Holy Bible in the vernacular is generally permitted without any distinction, more harm than utility is thereby caused, owing to human temerity: all versions in the vernacular, even by Catholics, are altogether prohibited, unless approved by the Holy See, or published, under the vigilant care of the Bishops, with annotations taken from the Fathers of the Church and learned Catholic writers. 8. All versions of the Holy Bible, in any vernacular language, made by non-Catholics, are prohibited; and especially those published by the Bible Societies, which have been more than once condemned by the Roman Pontiffs, because in them the wise laws of the Church concerning the publication of the sacred books are entirely disregarded. Nevertheless, these versions are permitted to students of theological or biblical science, under the conditions laid down above (No. 5). IV. OF OBSCENE BOOKS 9. Books which professedly treat of, narrate, or teach lewd or obscene subjects are entirely prohibited, since care must be taken, not only of faith, but also of morals, which are easily corrupted by the reading of such books.
