Since its release in 2007 the internet film Zeitgeist has been seen by 50 million people around the world. The film attacks the foundations of Christianity by claiming that the historical Jesus never existed. Jesus was originally a solar deity, whose story closely parallels several other pagan gods. The story of Jesus life is best understood as an astrological analogy. When the first Council of Nicaea met in 325 under the direction of the Roman Emperor Constantine, the Christ myth was rewritten as if it were real historical fact. While some of the ideas in the Zeitgeist film are based in fact, others are pure fiction. Tim Callahan, religion editor for Skeptic Magazine, joins us on the show to share his critique of the film.
