Aquinas on the Apocrypha

On the Commendation and Division of the Sacred Scriptures:

Jerome mentions a fourth kind of book, namely, the apocryphal, so called from apo, that is, ‘especially’, and cryphon, that is, ‘obscure’, because there is doubt about their contents and authors. The Catholic Church includes among the books of Sacred Scripture some whose teachings are not doubted, but whose authors are. Not that the authors are unknown, but because these men were not of known authority. Hence they do not have force from the authority of the authors but rather from their reception by the Church. Because there is the same manner of speaking in them and in the hagiographical works, they are for now counted among them.
