In the 3rd century BC, Jewish scholars translated the Hebrew Bible into Koine Greek. This Greek text, known as the Septuagint, is the canonical Old Testament of the Orthodox Church.

Eastern Christians, never having had a Protestant Reformation, have not removed the “apocrypha” from their Bibles. The Eastern Orthodox canon differs from both the Roman Catholic and Protestant canons.

Additional Comments:

According to Protopresbyter Michael Pomazansky’s Orthodox Dogmatic Theology:

The word “canonical” here has a specialized meaning with reference to the books of Scripture, and this must be distinguished from the more usual use of the word in the Orthodox Church, where it refers not to the “canon” of Scripture, but to “canons” or laws proclaimed at church councils. In the latter sense, “canonical” means “in accordance with the Church’s canons,” and “uncanonical” or “non-canonical” has the quite pejorative meaning of “not in accordance with the Church’s canons.” But in the former, restricted sense, “canonical” means only “included in the Hebrew canon”, and “non-canonical” means only “not included in the Hebrew canon” (but still accepted by the Church as Scripture). In the Protestant world the “non-canonical” books of the Old Testament are commonly called the “Apocrypha,” often with a pejorative connotation, even though they were included in the earliest printings of the King James Version, and a law of 1615 in England even forbade the Bible to be printed without these books. In the Roman Catholic Church since the 16th century the “non-canonical” books have been called “Deutrocanonical” — i.e. belonging to a “second” or later canon of Scripture. In most translations of the Bible which include the “non-canonical” books, they are placed together at the end of the canonical books; but in older printings in Orthodox countries there is no distinction made between the canonical and “non-canonical” books (see for example the Slavonic Bible printed in St. Petersburg, 1904, and approved by the Holy Synod).
