The Inspired Books: Westminster Confession 1:2-3

The books which are the rule (canon) for faith and life in the Church of Jesus Christ are the 39 books of the Hebrew Bible and the 27 books of the New Testament. The Apocryphal books added to the Hebrew Bible in the ancient Greek Septuagint (LXX) translation are not the Word of God. Jesus and his Apostles quote the Hebrew Bible constantly as being God's Word. They make no use of what are called the Apocryphal books. The main divisions of the Hebrew Bible are the Law, the Prophets, and the Writings (see Luke 24:44), but the order of books in our Bibles follows the somewhat different order of the LXX. The main external criterion for New Testament Scripture is apostolic authority, promised by Jesus (John 15:26-27, claimed by the Apostles themselves (I Corinthians 2:13), and supported by the signs which they did. Because Jesus is God's final Word to us, there will be no further inspired Scripture beyond the 66 books of the Bible.
