This volume on "The Christ" was written by one who recognizes in the Jesus of Strauss and Renan a transitional step, but not the ultimate step, between orthodox Christianity and radical Freethought. By the Christ is understood the Jesus of the New Testament. The Jesus of the New Testament is the Christ of Christianity. The Jesus of the New Testament is a supernatural being. He is, like the Christ, a myth. He is the Christ myth.
This is an easy to read and well referenced book on the question on the historicity of Jesus. The author looks at what has been claimed to be the evidence for Jesus and towards compares these to the older existing myths and legends of other sons of gods. At the end, whereas we can't be certain one way or the other, the story of Jesus is too fabulous to be real. It's creators went over themselves to embellish the character and it is this overdrive that will be the deathbed of the cult of Christ.
