Council of Trent: Session XXV, On The Index Of Books; On The Catechism, Breviary, And Missal

ON THE INDEX OF BOOKS; ON THE CATECHISM, BREVIARY, AND MISSAL.

The sacred and holy Synod, in the second Session celebrated under our most holy lord, Pius IV., commissioned certain chosen Fathers to consider what ought to be done touching various censures, and books either suspected or pernicious, and to report thereon to the said holy Synod; hearing now that the finishing hand has been put to that labour by those Fathers, which, however, by reason of the variety and multitude of books cannot be distinctly and conveniently judged of by the holy Synod; It enjoins that whatsoever has been by them done shall be laid before the most holy Roman Pontiff, that it may be by his judgment and authority terminated and made public. And it commands that the same be done in regard of the Catechism, by the Fathers to whom that work was consigned, and as regards the missal and breviary.
