This may or may not help, so if you don't want to question everything you thought you believed about Jesus, don't look...
Especially look down the list of contents and read the section on Human scapegoats.
I have no axe to grind, I have geat respect for what we believe we know about Jesus.But remember these examples are mainly long pre-Christian traditions.
Also please excuse the very non-PC language, it is an old book.
