I'm not sure that those who find comfort in an ever changing revelation that conforms to the culture of the day will like it.
Matthew 10:34
“Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword." ;)
You don't have to hold a doctorate in theology to understand that written information is much harder to change than oral information. It seems to me that for Christians the real discussion is about the accuracy of the translation, not what some guys make up in a back room.
Notice how the discussion changes to who's church is older and then quoting theologians who developed new doctrines not found in Scripture. It illustrates why Scripture must be the final authority.
As far as the nonsense about existing from the beginning, every Christian Church has the same claim. The Christians in the era immediately following the end of the Apostolic Era were not bound by a coercive centralized hierarchy, but were unified by a common faith. All Evangelicals hold to the same Gospel they did and are in unison with them because of it. It is the belief in The Gospel that makes us a part of the Body of Christ.
