The controversy over the Talpiot tomb has sparked any number of ad hominem attacks, but perhaps the most troubling is the undercurrent of Christian anti-semitism.  Witness the following from evangelical scholar Ben Witherington--the first argument he raises concerning the theory's credibility is the personal background of filmmaker Simcha Jacobovici:

"Why should we be skeptical about this entire enterprise?

First of all, I have worked with Simcha. He is a practicing Jew, indeed he is an orthodox Jew so far as I can tell."

Q.E.D.  This line of argument reminds me of what Catholic League President William Donohue said about opposition to Mel Gibson's The Passion of the Christ:

"Hollywood is controlled by secular Jews who hate Christianity in general and Catholicism in particular.  It‘s not a secret, OK?  And I‘m not afraid to say it.  That‘s why they hate this movie.  It‘s about Jesus Christ, and it‘s about truth.  It‘s about the messiah."
