As early as April, 1546, in the fourth session, a papal decree entitled _De editione et usu librorum sacrorum_ was received and accepted by the council. This presents the general grounds for the authority of the Vulgate, the principles that are to control the interpretation of the Scriptures, a prohibition of any wrongful use or citations of the works of the Bible, and, finally, instructions to the council to frame regulations for the supervision and control of the work of the printing-press, “the operations of which as now uncontrolled tend to pernicious license and injury to the faith of the community and to the authority of the Church.” Certain suggestions follow concerning the necessity for a close supervision of the text of the Scriptures to the end that it may be printed without error, omission, or interpolation, and the further necessity of forbidding the printing of any books having to do with religion or with the Scriptures which have not secured the approval of examiners appointed by the Church. The approval of such books must be given in writing and must be recorded in every written or printed copy. Anonymous books must in no case receive approval.[128] Two archbishops, Beccatelli and Selvaggio, deprecated the discussion of the subject as calculated to impede the principal object of the council; since Paul IV had, with the counsel and assistance of all the Inquisitions, formed a most complete catalogue, nothing could be added but books edited within the two years that had elapsed since its publication, an act undeserving of the labour of the synod. To reverse any condemnation in that Index would be to reflect imprudence on Rome; and while such action would lessen the authority of the Index of Paul, it would also injure the Council itself. In the redundance of books since the invention of printing, it were better that a thousand innocent ones should suffer than that one guilty should escape. Neither should reasons be given which would provoke opposition and would impair the dignity of laws that ought to rest simply upon their own authority. Correction and expurgation were likewise deemed inexpedient as tending to invite criticism and to make enemies. A contrary opinion, however, prevailed and at the eighteenth session, a decree was passed declaring that as the disease of pernicious books had not yielded to the salutary medicine hitherto applied, it was deemed proper that certain Fathers should be appointed diligently to examine and to state to the council what was necessary to be done respecting the censure of books. In its last session, the council referred to the judgment of the pope the work that had been prepared by its committee, and publication of the same was made in Rome in 1564.
