This book, "Misquoting Jesus" is one of the best books on the authencity of the Bible. Bart Ehrman, the author, was a fundamentalist Christian turned into agnostic, and he explains how the NT was often edited to suit their cultural beliefs. Also, remember, he was also a Biblical scholar and knows more about the Bible than you all do.
For example, the part when a woman was stoned for adultry and Jesus said, "Go sin no more" was NEVER found in any of the original manuscripts. It was added much later.
It is an important book for those who think the Bible is PURE and UNALTERED. His book proves beyond reasonable doubt that there were some edits through translations.
