Bible, called the Peshitta, was formalized, accepting Philemon, along with James, 1 Peter and 1 John, but excluding 2 John, 3 John, 2 Peter, Jude and Revelation. After the Council of Ephesus, the Church of the East became separated, and retained this canon of only 22-books (the Peshitta) up to the present day. The Syriac Orthodox Church uses this text as well (known in the West Syriac dialect as the Peshitto), but with the addition of the other books normally present in the New Testament canon. The late-5th or early-6th century Peshitta of the Syriac Orthodox Church includes a 22-book NT, excluding II Peter, II John, III John, Jude, and Revelation. The Lee Peshitta of 1823 follows the Protestant canon. , lists the following Syrian catalogue of St. Catherine's, c. 400: The Syriac Peshitta, used by all the various Syriac Churches, originally did not include 2 Peter, 2 John, 3 John, Jude and Revelation (and this canon of 22 books is the one cited by John Chrysostom (~347–407) and Theodoret (393–466) from the School of Antioch). It also includes Psalm 151 and Psalm 152–155 and 2 Baruch. Western Syrians have added the remaining 5 books to their NT canons in modern times (such as the Lee Peshitta of 1823). Today, the official lectionaries followed by the Malankara Syrian Orthodox Church, with headquarters at Kottayam (India), and the Chaldean Syrian Church, also known as the Church of the East (Nestorian), with headquarters at Trichur (India), still present lessons from only the 22-books of the original Peshitta. Armenian canon The Armenian Bible introduces one addition: a third letter to the Corinthians, also found in the Acts of Paul, which became canonized in the Armenian Church, but is not part of the Armenian Bible today. The Book of Revelation was not accepted into the Armenian Bible until c. 1200 AD when Archbishop Nerses arranged an Armenian Synod at Constantinople to introduce the text. Still, there were unsuccessful attempts even as late as 1290 AD to include in the Armenian canon several apocryphal books: Advice of the Mother of God to the Apostles, the Books of Criapos, and the ever-popular Epistle of Barnabas. The Armenian Apostolic church at times has included the Testaments of the Twelve Patriarchs in its Old Testament and the Third Epistle to the Corinthians, but does not always list them with the other 27 canonical New Testament books.
