You have noticed a society, commonly called the Bible society, boldly spreading throughout the whole world. Rejecting the traditions of the holy Fathers and infringing the well-known decree of the Council of Trent, it works by every means to have the holy Bible translated, or rather mistranslated, into the ordinary languages of every nation. There are good reasons for fear that (as has already happened in some of their commentaries and in other respects by a distorted interpretation of Christ’s gospel) they will produce a gospel of men, or what is worse, a gospel of the devil!
To prevent this evil, Our predecessors published many constitutions. Most recently Pius VII wrote two briefs, one to Ignatius, Archbishop of Gniezno, the other to Stanislaus, Archbishop of Mohileu, quoting carefully and wisely many passages from the sacred writings and from the tradition to show how harmful to faith and morals this wretched undertaking is.
In virtue of Our apostolic office, We too exhort you to try every means of keeping your flock from those deadly pastures. Do everything possible to see that the faithful observe strictly the rules of our Congregation of the Index. Convince them that to allow holy Bibles in the ordinary language, wholesale and without distinction, would on account of human rashness cause more harm than good.
INDEX OF PROHIBITED BOOKS OF 1930
What many, indeed fail to appreciate, and what, moreover non-Catholics consider a grave abuse — as they put it of the Roman Curia, is the action of the Church in hindering the printing and circulation of Holy Writ in the vernacular. Fundamentally however, this accusation is based on calumny. During the first twelve centuries Christians were highly familiar with the text of Holy Scripture, as is evident from the homilies of the Fathers and the sermons of the medieval preachers; nor did the ecclesiastical authorities ever intervene to prevent this. It was only in consequence of heretical abuses, introduced particularly by the Waldenses, the Albigenses, the followers of Wyclif, and by Protestants broadly speaking (who with sacrilegious mutilations of Scripture and arbitrary interpretations vainly sought to justify themselves in the eyes of the people; twisting the text of the Bible to support erroneous doctrines condemned by the whole history of the Church) that the Pontiffs and the Councils were obliged on more than one occasion to control and sometimes even forbid the use of the Bible in the vernacular… Those who would put the Scriptures indiscriminately into the hands of the people are the believers always in private interpretation — a fallacy both absurd in itself and pregnant with disastrous consequences. These counterfeit champions of the inspired book hold the Bible to be the sole source of Divine Revelation and cover with abuse and trite sarcasm the Catholic and Roman Church.
