(Robert Price, Deconstructing Jesus, p.162-163, my bold)I am not trying to say that there was a single origin of the Christian savior Jesus Christ, and that origin is pure myth; rather, I am saying that there may indeed have been such a myth, and that if so, it eventually flowed together with other Jesus images, some one of which may actually have been based on a historical Jesus the Nazorean. The old Christ-Myth theorists took for granted a single-root origin theory, just as orthodoxy did; it just chose a different candidate for the root.
According to Price, then Richard Carrier would be an old Christ-Myth theorist, because he thinks that the first Jew to hallucinate the archangel Jesus was Peter and only him.
But according to Carrier's definition of minimal historicity, Price would be a minimalist historicist or possibly a Jesus agnostic.
