The Deuterocanonical books (Greek: "Second Canon") are seven books, included in the Septuagint, which Catholics and Orthodox include in the Old Testament, but which Protestants generally do not. Classically they were called member of::Apocrypha by Protestants. But today the word Apocrypha denotes a class of literature that includes these deuterocanonical books plus several others of varying reputation for historical validity.
The term Deuterocanonical was first coined by Sixtus of Siena, a Roman Catholic theologian, in 1566. Catholics refer to these books are "deuterocanonical" because their canonicity was established after the protocanonical books. The Deuterocanonicals were affirmed as part of the Christian canon at Council of Rome in 382 AD, under Pope Damasus I and were reaffirmed at the Council of Carthage in 419 AD as well as the Second Council of Nicaea in 787 AD, Florence in 1442, Trent in 1546, and Vatican I in 1870.
The following books are regarded as deuterocanonical by the Catholic Church:
- Tobit (Tobias)
- includes::Ecclesiasticus, also called Sirach or Ben Sira.
- Baruch, including the includes::Letter of Jeremiah
- includes::1 Maccabees
- includes::2 Maccabees
As well as:
- The Rest of Esther (Vulgate Esther 10:4-16:24)
- The Rest of Daniel
- The Prayer of Azariah and Song of the Three Holy Children (Vulgate Daniel 3:24-90)
- Story of Susanna (Vulgate Daniel 13)
- The Idol Bel and the Dragon (Vulgate Daniel 14)
- Prayer of Manasses
These are the books which are more commonly referred to as the Deuterocanon. The Georgian Orthodox Church considers the Book of 4 Maccabees as part of their canon, while it is only an appendix to the Bible of the Greek Orthodox Church.
The Eastern Orthodox Church accepts the same books as the Roman Catholic Church listed above as deuterocanonical. These are called Anagignoskomena (ἀναγιγνωσκόμενα) by the Greek Church. In addition the seven books, already mentioned, the Orthodox accept three or four others as part of their Deuterocanon:
