What differences, Isa? I’d be fascinated to know this. We, too, have a different take on the canon than most Protestants and Catholics (though we always get lumped in the generic Protestant groups. Bleah).
We have a few more books: 4 Maccabbees for one (an interesting book because it dates perhaps within the Lord’s lifetime on earth, and its theology is VERY Christian: the argument that the Abrahm, Isaac and Jacob live to/in God is like the Lord’s argument to the Sadduccees), Psalm 151 (a version of which was found in the Dead Sea Scrolls) and others. All of them except 4 Maccabbees and II Esdras are in the new “The Orthodox Study Bible: Ancient Christianity Speaks to Today’s World,” a translation of the Septuagint (LXX).
The “reabable” part deals with how the Church uses them, especially liturgically. That is how they were canonized.
The Gospels are bound together in a book which has an icon of the Crucifixion on the one side and the Resurrection on the other (the reason why that is important is because the liturgical day begins at sunset, as in Genesis. During Vespers for the Sunday Vigil, i.e. Saturday night (the origin of Saturday mass), the priest processes in with the Gospel with the Crucifixion showing, as we sing “O Glandsome Light” (a twilight hymn so old that St. Basil (4th cent.) said the author had been long lost. He then turns it to show the Resurrection, to show that the Resurrection has dawned on us an Sunday, the Lord’s Day, has begun, and enthrones it on the altar). The Order is not by books, but by the proscribed sections by the Lectionary. It contains only the Gospel readings, to show the sufficency of Christ, and as an icon of His teaching ministery. Some Orthodox will only venerate the Gospels and not the rest of the Bible (the Gospels are venerated during Matins, the morning prayer).
The Epistles are in the Apostolos, and again the readings are in the order of the Lectionnary, not the books. It includes Acts, which is read all through out Pascha time, because the Church is Body of Christ in history and in this world. btw, historically the Epistle of Clemant was almost canonized because the Church of Corinth, to whom he sent it, was read every year. The missing epistles of St. Paul to that same Church are missing because that Church never read them at Divine Liturgy.
The Book of Revelation is read only on one day of the year, Great and Holy Saturday, in the Paschal Virgil before the icon of Christ entombed (the epitaphion), which is the Vigil of this Age waiting for the Age to come. It canonizes, however, the basis of the liturgical forms (if you are Orthodox, you realize that St. John is at Divine Liturgy when he sees his vision, and then sees worship in heaven, the prototype. The Church actively discourages reading Revelation, as it belongs to the age to come, and too much speculation leads to bad results (look at the JW).
The OT testiment is read a lot during Great Lent, as a preparation for Pascha, just like the OT was the preparation for the NT. That is in the Lenten Triodion, which includes the services for the weeks of Preparation for Lent up to and including Great and Holy Saturday. For that reason also, the readings During the Vesperal Liturgy of Pascha (Saturday evening, Sunday Matins and Midnight DL is main Paschal Service), which is the longest of the year (and the only time we read the hymn of St. James, Christ’s Brother “Let all mortal flesh keep silent”) there is a series of readings for Salvation History, Genesis, Exodus, Joshuah, Kings, Isaiah, Jerimiah, Daniel, (Ezekiel (the Valley of the Dry Bones) is read on Great and Holy Friday before the entombed Christ) Jonah, etc. The major feasts days have OT readings at their Vigils (e.g. feasts of the Virgin Mary, or Theotokos, have various readings on the Temple).
The Psalter is in one book because they are read at every service (the hours consist of psalms interspersed with prayers), cf. the number of prophecies from it in the NT. It used to be the rule that anyone who was to recieve orders in the Church had to memorize the entire psalter first.
Then there are books which include the “DC.” Sirach is not read in the DL, but it was an is used a lot by the Church for catechisis (was so by the rabbis too, becasue they quote and comment on it in the Talmud, but evidently its popularity in the Church was its downfall in the Synagogue. The Hebrew text was rediscovered a century ago). So too Maccabbees etc, they were used for edification, which is akin to what I remember Martin Luther saying about them.
Then there are works, like the Proto-evangelion of James which has influenced Church tradition (it is the basis of the life of the Theotokos and her feastday before the Annuciation), but has never been read in Church, and at one point was actually forbidden to be read in Church services but only privately. Then there are books read in Divine Liturgy but which have never been seen as part of the Canon, e.g. the Synaxarion, which contains lives of the saints, commentary on the feastdays of Christ, etc.
So for one thing, until recently it was not usual to have the whole Bible between two covers, as it was split up according to the Church’s uses. Hence not a big deal what was between the two covers of the Bible as the Puritans and Evangelicals would have us believe. Hence the issue of “canon” as Protestants and the Vatican argue, isn’t such a burning issue for us.
