JM explains the weakness of modern textual criticism:
Those who prefer to use a rational approach in defining the New Testament text have to admit that scripture is selected by the text critic. In the office of a scholar many manuscripts are studied. The assumption is often stated that “only the originals are inspired.” The scholar must conduct examinations of the many manuscripts to determine which verse is more likely to be inspired and therefore authentic. But what kind of method does he use? What is his rule to determine what is, might be or is not scripture? The Bible critic or critics, whatever the case maybe, must choose and whatever kind of rule chosen, becomes their guiding principle. It is not driven by the logic of faith the Reformers used but a secular naturalistic presupposition. This presupposition denies the God who acts in history and intervenes in our daily lives. It denies what scriptures reveals about itself.
