Summary: The Bible has been transmitted through various means. The Septuagint and Masoretic Text are based on slightly different Hebrew originals, with most scholars arguing the LXX’s “Vorlage” is older than the MT’s. One of the most noteworthy elements differing between these textual traditions is the chronology’s presented in Genesis 5 and 11. But didn’t the MT protect the text from changes? Isn’t the MT version the one that Young Earth Creationists rely upon? What are the ancient codices and why are they important to assure us that we have authentic copies of the originals, the “autographs”?
