St. Jerome cast his weighty suffrage on the side unfavourable to the disputed books. In appreciating his attitude we must remember that Jerome lived long in Palestine, in an environment where everything outside the Jewish Canon was suspect, and that, moreover, he had an excessive veneration for the Hebrew text, the Hebraica veritas as he called it. In his famous “Prologus Galeatus”, or Preface to his translation of Samuel and Kings, he declares that everything not Hebrew should be classed with the apocrypha, and explicitly says that Wisdom, Ecclesiasticus, Tobias, and Judith are not on the Canon. These books, he adds, are read in the churches for the edification of the people, and not for the confirmation of revealed doctrine. **An analysis of Jerome’s expressions on the deuterocanonicals, in various letters and prefaces, yields the following results: first, he strongly doubted their inspiration; **secondly, the fact that he occasionally quotes them, and translated some of them as a concession to ecclesiastical tradition, is an involuntary testimony on his part to the high standing these writings enjoyed in the Church at large, and to the strength of the practical tradition which prescribed their readings in public worship. Obviously, the inferior rank to which the deuteros were relegated by authorities like Origen, Athanasius, and Jerome, was due to too rigid a conception of canonicity, one demanding that a book, to be entitled to this supreme dignity, must be received by all, must have the sanction of Jewish antiquity, and must moreover be adapted not only to edification, but also to the “confirmation of the doctrine of the Church”, to borrow Jerome’s phrase.
