Priests have not always been consulted. The moment a Catholic perceives a book to be dangerous to his faith or morals he knows from the doctrine concerning occasions of sin that he is obliged to cease reading it. Each is his own censor to a certain extent. In doubt, a book could be given to a Priest to read. The moment the Priest finds that book is undoubtedly evil in itself, he closes it and forbids it. If it needs reading right through for purposes of refutation, he secures permission from the Bishop and does it as a duty. Just as doctors have at times to attend to patients in a way which would be postively sinful for a non-professional man, so a Priest may have to study books to safeguard morals, books forbidden to those who have not the public duty. The Priest in this case would commit no sin, where others would do so.
