Well this thread went the way of its namesake.
Eastern Orthodoxy /Orthodox Christianity (not Jewish) is the collective name under which the early Church that remains, and has spread, is now called. That's not triumphalism btw, it's Church History. Scriptures refer to the Church at Rome, the Church at Jerusalem, the Church at Antioch, and so on. The Church was simply the Church, in one communion, sharing essentially all beliefs and practices (yes I'm oversimplifying some details).
Rome over a few centuries made some changes but mainly over the matter of whether she had supreme authority - led to a division. At that point Rome began Catholicism. The rest of the Church remained and basically has made it a major goal to maintain the faith, where Rome saw development as a good thing. The Protestant reformation was an attempt to reform Rome, and later denominations further reformed the reformers. That is the basic pedigree of Christianity. Orthodoxy has basically had no part of all that, just continuing to exist, maintaining the same faith, often under persecution.
Many Protestants assume that the Orthodox are just another denomination that picked up the same Bible they did, interpreted it differently in some places (depending on which kind of Protestant), and tried to make a cohesive but competing theology, because that's what Protestants do.
But that is not our history. Many of the Churches you read about in Scripture are still there, have never changed, and we are in communion with them.
Our practices and beliefs don't come from Scripture, because they mostly come from actime from before Scripture was written, and certainly before it was canonized. They come from the Apostles. In fact, that's HOW Scripture came to be recognized as Scripture - because it agreed with what the Church believed. Not the other way around. There were as many competing documents circulated that were not accepted, sometimes because the teaching in them was false, sometimes because the authorship was not accepted.
It is impossible for Scripture and Orthodoxy not to agree (unless Orthodoxy has changed, and by reading ancient documents it can be demonstrated that it has not). If you knew Orthodoxy you would see even that there's a joke in there about us ... we do NOT change what we believe and that is steadfastly resisted at all costs.
I think I'll leave it at that.
By all means, we welcome debate in St. Justin's forum, if someone wishes to challenge or debate anything. We do ask to keep TAW proper a peaceful place. This is a strict time of fasting in Orthodoxy as well, so I would ask understanding that we might not be at our most gracious right now.
Peace to all.
