“[Seripando was] Impressed by the doubts of St. Jerome, Rufinus, and St. John Damascene about the deuterocanonical books of the Old Testament, Seripando favored a distinction in the degrees of authority of the books of the Florentine canon. The highest authority among all the books of the Old Testament must be accorded those which Christ Himself and the apostles quoted in the New Testament, especially the Psalms. But the rule of citation in the New Testament does not indicate the difference of degree in the strict sense of the word, because certain Old Testament books not quoted in the New Testament are equal in authority to those quoted. St. Jerome gives an actual difference in degree of authority when he gives a higher place to those books which are adequate to prove a dogma than to those which are read merely for edification. The former, the protocanonical books, are “libri canonici et authentici”; Tobias, Judith, the Book of Wisdom, the books of Esdras, Ecclesiasticus, the books of the Maccabees, and Baruch are only “canonici et ecclesiastici” and make up the canon morum in contrast to the canon fidei. These, Seripando says in the words of St. Jerome, are suited for the edification of the people, but they are not authentic, that is, not sufficient to prove a dogma. Seripando emphasized that in spite of the Florentine canon the question of a twofold canon was still open and was treated as such by learned men in the Church. Without doubt he was thinking of Cardinal Cajetan, who in his commentary on the Epistle to the Hebrews accepted St. Jerome’s view which had had supporters throughout the Middle Ages.”

“For the last time [Seripando] expressed his doubts [to the Council of Trent] about accepting the deuterocanonical books into the canon of faith. Together with the apostolic traditions the so-called apostolic canons were being accepted, and the eighty-fifth canon listed the Book of Sirach (Ecclesiasticus) as non-canonical. Now, he said, it would be contradictory to accept, on the one hand, the apostolic traditions as the foundation of faith and, on the other, to directly reject one of them.”
