This episode mostly addresses the issue of textual variants. The reason why Critical Text theorists insists on an "older is better" approach to manuscripts is that less chance exists of a copying error occurring when a manuscript is older, closer to the original autograph. Copying over the last 1,900 years has in fact led a large number of textual variants. A textual variant is a difference in wording between 2 or more texts. While this fact alone might cast doubt over transmission of the original autograph, as critics like Bart Ehrman point out, a "textual variant" includes numerous differences that don't change the meaning at all, especially spelling variants, inclusion or absence of the definite article, word order differences, and transposition of words. The vast majority of textual variants don't alter meaning AT ALL. None exists that would alter any central tenet of the Christian faith. Future episodes address the very few substantive variants.
