I really like this chart from Yuriy and Inna's blog. It demonstrates the dependence of New Testament writings on, not the Hebrew Bible and the much trumpeted Masoretic Text, but the Greek Septuagint (LXX).
Yuriy's series of posts, Why I Don't Trust The Bible, is worth checking out. He describes himself as a recovering Pentecostal fundamentalist.
