Quote: Some things in the Gospels seem intended to explain away inconsistencies between the man and the theology, which wouldn't be necessary with a completely fictional character.
You are forgetting that there was not one xtianity until the proto-orthodox triumph in the 4th century at which time they set about stamping out all the variants. I suggest Bart Ehrman's Lost Christianities for a fuller understanding of what was really going on before the church cobbled together their bullshit story.
