The Jesus Mysteries: Was the 'Original Jesus' a Pagan God?

""Whether you conclude that this book is the most alarming heresy of the millennium or the mother of all revelations, The Jesus Mysteries deserves to be read."
-- Fort Worth Star -Telegram
What if . . .
* there were absolutely no evidence for the existence of a historical Jesus?
* for thousands of years Pagans had also followed a Son of God?
* this Pagan savior was also born of a virgin on the twenty-fifth of December before three shepherds, turned water into wine at a wedding, died and was resurrected, and offered his body and blood as a Holy Communion?
* these Pagan myths had been rewritten as the gospel of Jesus Christ?
* the earliest Gnostic Christians knew that the Jesus story was a myth?
* Christianity turned out to be a continuation of Paganism by another name?
