The "Hero With a Thousand Faces" is awesome! Have you read Campbell's other books? I'm reading "Thou Art That" at the moment.Indeed, the word 'myth' is misused. It is essentially identified with 'falsehood' in the popular media. I have considered Christianity a myth ever since reading The Hero with a Thousand Faces. Myths have a reality which transcends a mere literal understanding.
Just a side note: astrology and reincarnation have nothing to do with pantheism. Pantheism refers to the belief that the totality of the universe and all it contains is equivalent to a god.I read an article the other day in some magazine or other at the doctor's office, that more and more Christians are becoming more pantheistic as time goes on. They referenced the belief in astrology and reincarnation as two particular beliefs that more Christians are starting to believe in. Interesting I thought.
