(For 367.) Of the particular books and their number, which are accepted by the Church. From the thirty-ninth Letter of Holy Athanasius, Bishop of Alexandria, on the Paschal festival; wherein he defines canonically what are the divine books which are accepted by the Church....1. They have fabricated books which they call books of tables, in which they show stars, to which they give the names of Saints. And therein of a truth they have inflicted on themselves a double reproach: those who have written such books, because they have perfected themselves in a lying and contemptible science; and as to the ignorant and simple, they have led them astray by evil thoughts concerning the right faith established in all truth and upright in the presence of God....2.
But since we have made mention of heretics as dead, but of ourselves as possessing the Divine Scriptures for salvation; and since I fear lest, as Paul wrote to the Corinthians, some few of the simple should be beguiled from their simplicity and purity, by the subtlety of certain men, and should henceforth read other books— those called apocryphal— led astray by the similarity of their names with the true books; I beseech you to bear patiently, if I also write, by way of remembrance, of matters with which you are acquainted, influenced by the need and advantage of the Church.
