There are over five thousand extant Greek New Testament manuscripts that range in size from the whole New Testament to scraps of papyri that contain as little as a part of a single verse. A few fragments date to within twenty-five to fifty years of the original writing. New Testament textual scholars have generally concluded that over 99 percent of the original writings have been reclaimed, and that of the remaining potentially alternate readings, there are no variants substantially affecting any Christian doctrine.
