“The record is really quite astonishing. The New Testament contains about twenty thousand lines of text, and of those, only about forty lines are in question. That amounts to about four hundred words (roughly one page of your two-hundred-page New Testament). Most of the variations are insignificant to the meaning of the text: it says about the same thing either way. Of the variations that remain, no major doctrine is affected by or built upon those texts. So everything that really matters to Christianity comes out of well-attested ancient texts.”[1]
