I'm afraid I don't understand what this means. :)
That means, FK, that not all "originals" are the same. The oldest New Testament (Sinaiticus) dates some 300 years after Christ. We are reading copies of copies my friend. Welcome to the wonderful world of the Unknown Bible that nobody told you about. And you thought the Bible just dropped from the sky, signed, sealed and delivered by God?
As you go through this journey on the Forum, you will learn that Tradition is not the only thing Protesants should wonder about but that the Bible you read will depend on which "original" was used. :)
FK, my answer got so long -- amounting to a brief history of Greek manuscript traditions, that I will FReepmail it to you rather than burden the thread with it.
