The creation of the Christ myth from out of the Jewish life and Roman death of Jesus of Nazareth is one of the greatest stories ever told. Including the extraordinary use by the Evangelists of the Hebrew scriptures.
The Christ myth is brilliant, powerful and seductive, at least for those ignorant of Hebrew scripture and messianism.
The point is not to"debunk" scripture but to understand it: ...who wrote it, when, where and why? What did it sound like and what did it mean to the authors and their original and earliest audience? Who compiled, edited, combined, redacted, or plagiarized? Who created the pseudepigraphia? Etc.
The Bible is endlessly fascinating. Whose fault is it if it helps get some people through the day, and what's the harm?
