From Our Reformed Doctrinal Standards
Belgic Confession of Faith
Article 5 - From whence the Holy Scriptures derive their dignity and authority
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 Ghost witnesseth in our hearts, that they are from God, whereof they carry the evidence in themselves. For the very blind are able to perceive that the things foretold in them are fulfilling.
Article 6 - The difference between the canonical and apocryphal books
We distinguish those sacred books from the apochryphal, viz.: the third book of Esdras, the books of Tobias, Judith, Wisdom, Jesus Syrach, Baruch, the appendix to the book of Esther, the song of the three Children in the Furnace, the history of Susannah, of Bell and the Dragon, the prayer of Manasses, 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, as that we may from their testimony confirm any point of faith, or of the christian religion; much less detract from the authority of the other sacred books.
