Read the following excerpt from the Council of Trent, Eighteenth Session:

Whereas, then, first of all, it has noticed that the number of suspected and pernicious books, wherein an impure doctrine is Contained, and is disseminated far and wide, has in these days increased beyond measure, which indeed has been the cause that many censures have been, out of a godly zeal, published in divers provinces, and especially in the fair city of Rome,--and yet that no salutary remedy has availed against so great and pernicious a disorder; It hath thought good, that Fathers specially chosen for this inquiry, should carefully consider what ought to be done in the matter of censures and of books, and also in due time report thereon to this holy Synod; to the end that It may more easily separate the various and strange doctrines, as cockle from the wheat of Christian truth, and may more conveniently deliberate and determine, in regard thereof, that which shall seem best adapted to remove scruples from the minds of very many, and to do away with various causes of complaint.—Public Domain
