 Rewrite   This article needed a rewrite to bring it up to encyclopedic standards.  I tried to do that, while still preserving as much of the original material as possible and adding some new information and links (to Dr. Bernard's book and Jason Dulle's website, which might prove helpful for readers), as well.  Please feel free to edit, change or even revert it if you feel another version would be better!  God bless!
