The canon of sacred texts is affirmed by sacred tradition and also various decrees from the Quinisext Council which was not recognized by Rome but is considered a canonical element of the 5th and 6th OEcumenical Councils in the East. In general we accept the same books as those found in Catholic Bibles but we also recognize 3rd Maccabees (and in the case of the Georgian Church 4th Maccabees), 3rd Ezra (and in the case of the Georgian Church 4th Ezra), Psalm 151 and the Letter of Jeremiah (which in the Roman Church is called chapter 6 of Baruch).
The only English language edition that I am familiar with and that is Orthodox, is the Orthodox Study Bible.
Interesting. I knew that there were other differences, but I never knew that we used different bibles.
