The Bible derives its authority from its Author, who (we agree) was God.Really was God the author of the Bible? The Muslims believe that God was the author of the Koran and it was dropped straight from Heaven. We Christians don't believe that the Bible was written by God the Almightly Himself. The only part of the Bible that God himself wrote may be was the Ten Commandments. All the others were written by fallen men. Ofcouse they were guided by the Holy Spirit. So the Bible includes words of fallen men. These men used words that other fallen men could understand; like attributing; 'wrath' and 'anger' and 'vengence' etc to a God who was always loving his entire creation. Those words were used so that people living at that time and culture, could be guided to morality and from immorality.
(Not all this is to to you, Timon, just using this as a springboard.)
It might seem, admitting that the Bible was written by fallible men means that it is (ultimately) subject at all times to the authority of 'the Church' as to its exact contents and correct interpretation. Since the Orthodox (and Catholics, Protestants, whoever) have such a field day with wild disagreements as to 'proper' moral strictures and guidelines (or canons, at least) passed down from the Church apart from that within the canon of Old and New Testaments, opening up the canon itself should be the logical end of such 'wild disagreement'. This is theoretical of course, since I believe it has been 1,400 years since 'the Church' acted to add or subtract from the canon. But just the prospect - I can imagine the Apocalypse of St. John being a prime candidate, just as it was the last addition - of the Orthodox Church removing a book of Holy Scripture (it is, after all, within her authority, no?) is too frightening a thought - to me, anyway.
I suppose 'they' (the Orthodox... you?) would say that the Church would never remove a part of Scripture that was added, and has been 'fixed' for so long. Still could say that, theoretically, it's possible. Personally, almost as aggravating is the tendency to change the interpretation or emphasis (emphases) of various Scriptures over time, calling it 'revelation' perhaps - so that, for example, the understood belief of Holy Orthodoxy presented today seems to include that Hell as a place does not exist, and whatever it is eternally people only choose to hate God themselves, nothing is a reward for bad works or unbelief (the lone reward perhaps for pride). This is only my impression from reading several years on this forum, and a few bits from proponent theologians. (For what it's worth, this view echoes among most young Christians today, evangelical Protestants included I think.)
All this... trying to say that, I don't see much advantage claiming the authority of one 'Church' over the Scriptures, and that kind of superceding authority is asserted when it's said "the Church wrote
the Scriptures". All it does (for me, again) is widen the scope of misrepresentation, possible heresy and apostasy, all manner of confusion etc. The Bible (in translations) represents a fixed work, while the Church represents one (or many) continuing on in an organic, "evolving" way, therefore it can (and I believe does) change where the text of the Scriptures does not. I can't logically or scientifically (?) follow up on this impression, but for what it is, the Bible holds more consolation within it than the plethora of beautiful images and sounds within the real-world Orthodox Church. (Could say the same for the Roman Catholic and Protestant forms, none of which I think are as beautiful as the Orthodox, which is a sadness.)
