]Rule 10. Episcopal approbation, to be printed in the beginning or at the end of the book, is required for all editions of the Bible or parts of the Bible in any language, likewise for all prayer books, books of devotion and of practical piety. Without episcopal authorization such publications are forbidden, though they may have been issued by the most learned and pious men.
Note 1. Leaflets which are so small that they cannot be called books, or even booklets or pamphlets, do not fall under this law. But if they are not approved by the bishop, the duty of making sure that they contain nothing erroneous devolves upon those who use them.
Summaries of indulgences, however, no matter how small, always need episcopal approbation and may not be circulated without it.
Note 2. All editions of the Bible, edited by non-Catholics, in ancient as well as modern languages, are permitted to those, and those only, who are engaged in serious theological or biblical studies, provided, however, that the PROLEGOMENA [56] ]AND ANNOTATIONS do not of set purpose impugn the Catholic faith. It is not enough that the text itself is faithfully and completely rendered.
