PRINCIPAL LAWS OF THE COUNCIL OF TRENT
II. ON SACRED SCRIPTURE:
If anyone, however, should not accept the said books as sacred and canonical, entire with all their parts, as they were want to be read in the Catholic Church, and as they are contained in the old Latin Vulgate edition, and if both knowingly and deliberately he should condemn the aforesaid traditions; let him be anathema.
…Moreover, the same sacred and holy Synod … ordains and declares that the said old Vulgate edition, which has been approved by the Church itself through long usage for so many centuries, be, in public lectures, disputations, sermons, and expositions, held as authentic; and that no one is to dare or presume to reject it under any pretext whatever.
