There's a short called Zombie Jesus.

Tom Savini plays a zombie Jesus in Zombiegeddon.

The Passion Of Zombie Jesus.

And in the Worst Horror Film Ever Made (actual title) Jesus comes back, is crucified by gay Muslim terrorists, masturbates using the holes in his hands, goes on a rape bender, is raped to death by trees (ala Evil Dead) and then comes back as a rape-happy Zombie.

And of course there's the Jesus Hates Zombies graphic novels

So is it down to ......

1. Rising from the dead?
2. The whole transmutation/eating of the flesh thang?
3. The mindless followers?
4. All of the above?
5. Good old taboo busting?
