It's serious research about the creation of the Christ story.. like the whole Roman empire washing (pilatus) it's hands in innocence etc.

It's talks with researchers about the ehmm basically coming together of the new testament and the parralells it shows with how the roman Empire used to 'take over' other religions in a sneaky way.

It's not so much Christ myth (although it is abit according to the wikipedia definition, Jesus Christ is a rank/title, not a birth name) But they go about Yoshua one of the possible real names) but that the roman empire twisted his rebelion into something else.

The intro is always a bit of a puts sunglasses on goof, but the interviews are very nice. (the whole podcast is very good, just skip the intro for beginners, it's a media-remix he likes to do)
