Free Misquoting Jesus by Bart D. Ehrman Page A

God. Marcion’s “orthodox” opponent Irenaeus claimed that Marcion did the following:
    dismembered the epistles of Paul, removing all that is said by the apostle respecting that God who made the world, to the effect that He is the Father of our Lord Jesus Christ, and also those passages from the prophetical writings which the apostle quotes, in order to teach us that they announced beforehand the coming of the Lord. (Against Heresies 1.27.2)
    Marcion was not the only culprit. Living roughly at the same time as Irenaeus was an orthodox bishop of Corinth named Dionysius who complained that false believers had unscrupulously modified his own writings, just as they had done with more sacred texts.
    When my fellow-Christians invited me to write letters to them I did so. These the devil’s apostles have filled with tares, taking away some things and adding others. For them the woe is reserved. Small wonder then if some have dared to tamper even with the word of the Lord himself, when they have conspired to mutilate my own humble efforts.
    Charges of this kind against “heretics”—that they altered the texts of scripture to make them say what they wanted them to mean—are very common among early Christian writers. What is noteworthy, however, is that recent studies have shown that the evidence of our surviving manuscripts points the finger in the opposite direction. Scribes who were associated with the orthodox tradition not infrequently changed their texts, sometimes in order to eliminate the possibility of their “misuse” by Christians affirming heretical beliefs and sometimes to make them more amenable to the doctrines being espoused by Christians of their own persuasion. 11
    The very real danger that texts could be modified at will, by scribes who did not approve of their wording, is evident in other ways as well. We need always to remember that the copyists of the early Christian writings were reproducing their texts in a world in which there were not only no printing presses or publishing houses but also no such thing as copyright law. How could authors guarantee that their texts were not modified once put into circulation? The shortanswer is that they could not. That explains why authors would sometimes call curses down on any copyists who modified their texts without permission. We find this kind of imprecation already in one early Christian writing that made it into the New Testament, the book of Revelation, whose author, near the end of his text, utters a dire warning:
    I testify to everyone who hears the words of the prophecy of this book: If anyone adds to them, God will add to him the plagues described in this book; and if anyone removes any of the words of the book of this prophecy, God will remove his share from the tree of life and from the holy city, as described in this book. (Rev. 22:18–19)
    This is not a threat that the reader has to accept or believe everything written in this book of prophecy, as it is sometimes interpreted; rather, it is a typical threat to copyists of the book, that they are not to add to or remove any of its words. Similar imprecations can be found scattered throughout the range of early Christian writings. Consider the rather severe threats uttered by the Latin Christian scholar Rufinus with respect to his translation of one of Origen’s works:
    Truly in the presence of God the Father and of the Son and of the Holy Spirit, I adjure and beseech everyone who may either transcribe or read these books, by his belief in the kingdom to come, by the mystery of the resurrection from the dead, and by that everlasting fire prepared for the devil and his angels, that, as he would not possess for an eternal inheritance that place where there is weeping and gnashing of teeth and where their fire is not quenched and their spirit does not die, he add nothing to what is written and take nothing away from it, and make no insertion or alteration, but that he
