Unapproved Vernacular Bibles Have Always Been the Weapon of Heretics
4. Moreover, regarding the translation of the Bible into the vernacular, even many centuries ago bishops in various places have at times had to exercise greater vigilance when they became aware that such translations were being read in secret gatherings or were being distributed by heretics. Innocent III issued warnings concerning the secret gatherings of laymen and women, under the pretext of piety, for the reading of Scripture in the diocese of Metz.[12] There was also a special prohibition of Scripture translations promulgated either in Gaul a little later[13] or in Spain before the sixteenth century.[14] But later even more care was required when the Lutherans and Calvinists dared to oppose the changeless doctrine of the faith with an almost incredible variety of errors. They left no means untried to deceive the faithful with perverse explanations of the sacred books, which were published by their adherents with new interpretations in the vernacular. They were aided in multiplying copies and quickly spreading them by the newly invented art of printing. Therefore in the rules written by the fathers chosen by the Council of Trent, approved by Pius IV,’s and placed in the Index of forbidden books, we read the statute declaring that vernacular Bibles are forbidden except to those for whom it is judged that the reading will contribute “to the increase of faith and piety.”[16] Because of the continued deceptions of heretics, this rule was further restricted and supplemented by a declaration of Benedict XIV: for the future the only vernacular translations which may be read are those which “are approved by the Apostolic See” or at least were published “with annotations taken from the holy Fathers of the Church, or from learned and Catholic authors.”[17]
