Ah Zeitgeist, one of the biggest headaches I've had in a long while. I've seen it many times and worked through the video with people to show them where it is clearly wrong, and how reliable it is. I doubt very much if even those who support the Jesus Myth hypothesis look upon this movie as anything but shameful.
It is an attack on uneducated American Evangelical fundamentalists.
That said, the reason it's such a headache is because of how indoctrinating it is for those who don't know better, and how false it is. It's like the DaVinci Code, except not nearly as clearly wrong. Or like the Muslim arguments surrounding Deuteronomy 18 and the Gospel of Barnabas. Or ID...
But no, in seriousness, this video should only cause the weak to falter. I think one day I'll write out my points against it instead of just work with every individual who brings it to me, again and again. The problem though, is that it's almost not worth dignifying with a response.
When Celsus attacked Christianity in the second Century, and Origen's friend asked him to refute Celsus' book "the True Word", Origen said the following;
"When false witnesses testified against our Lord and Saviour Jesus Christ, He remained silent; and when unfounded charges were brought against Him, He returned no answer, believing that His whole life and conduct among the Jews were a better refutation than any answer to the false testimony, or than any formal defence against the accusations..." - "Jesus... is at all times assailed by false witnesses, and, while wickedness remains in the world, is ever exposed to accusation. And yet even now He continues silent before these things, and makes no audible answer, but places His defence in the lives of His genuine disciples, which are a pre-eminent testimony, and one that rises superior to all false witness, and refutes and overthrows all unfounded accusations and charges..."
He went on to make the point that the second Christians give a reply to these kinds of silly things, it makes it seem almost as though there is even some kind of an argument to be had at all.
Just the same, this movie seems to be bothering an unsettling number of people. I might eventually write out my points.
