Every year, several New Testament manuscripts handwritten in the original Greek format are discovered. The latest substantial find was in 2008, when 47 new manuscripts were discovered in Albania; at least 17 of them unknown to Western scholars. There has been an estimate of 400,000 variations among all these manuscripts (from the 2nd to 15th century). If you spread those 400,000 variations over 5,600 manuscripts, that comes out to only about 71 variations per manuscript, (400,000 divided by 5,600). And some of these manuscripts are the equivalent of several hundred pages of text, hand-written (see Codex Vaticanus, Codex Alexandrinus, et al.). The number of variants is additionally less significant than may appear since it is a comparison across linguistic boundaries. More important estimates focus on comparing texts within languages. Those variations are considerably fewer. The vast majority of these are accidental errors made by scribes, and are easily identified as such: an omitted word, a duplicate line, a misspelling, a rearrangement of words. Some variations involve apparently intentional changes, which often make more difficult a determination of whether they were corrections from better exemplars, harmonizations between readings, or ideologically motivated. Variants are listed in critical editions of the text, the most important of which is the Novum Testamentum Graece, which is the basis for most modern translations. For over 250 years, Christian scholars have argued that no textual variant affects key Christian doctrine.
