We receive all these books, and these only, as holy and canonical, for the regulation, foundation, and confirmation of our faith; believing without any doubt all things contained in them, not so much because the Church receives and approves them as such, but more especially because the Holy Spirit witnesses in our hearts that they are from God, and also because they carry the evidence thereof in themselves. For the very blind are able to perceive that the things foretold in them are being fulfilled.
We distinguish those sacred books from the apocryphal, viz: the third and fourth books of Esdras, the books of Tobit, Judith, Wisdom, Jesus Sirach, Baruch, the Appendix to the book of Esther, the Song of the Three Children in the Furnace, the History of Susannah, of Bel and the Dragon, the Prayer of Manasseh, and the two books of the Maccabees. All of which the Church may read and take instruction from, so far as they agree with the canonical books; but they are far from having such power and efficacy that we may from their testimony confirm any point of faith or of the Christian religion; much less may they be used to detract from the authority of the other, that is, the sacred books.
We believe that those Holy Scriptures fully contain the will of God, and that whatsoever man ought to believe unto salvation is sufficiently taught therein. For since the whole manner of worship which God requires of us is written in them at large, it is unlawful for any one, though an apostle, to teach otherwise than we are now taught in the Holy Scriptures: nay, though it were an angel from heaven, as the apostle Paul says. For since it is forbidden to add unto or take away anything from the Word of God, it does thereby evidently appear that the doctrine thereof is most perfect and complete in all respects.
Neither may we consider any writings of men, however holy these men may have been, of equal value with those divine Scriptures, nor ought we to consider custom, or the great multitude, or antiquity, or succession of times and persons, or councils, decrees or statutes, as of equal value with the truth of God, since the truth is above all; for all men are of themselves liars, and more vain than vanity itself. Therefore we reject with all our hearts whatsoever does not agree with this infallible rule, as the apostles have taught us, saying, Prove the spirits, whether they are of God. Likewise: If any one cometh unto you, and bringeth not this teaching, receive him not into your house.
