In Evidence That Demands a Verdict, Josh McDowell makes an argument that is common among apologists: “There are now more than 5,300 known Greek manuscripts of the New Testament. Add over 10,000 Latin Vulgate and at least 9,300 other early versions (MSS) and we have more than 24,000 manuscript copies of portions of the New Testament in existence today. No other document of antiquity even begins to approach such numbers and attestation.
