[I seem to have written this poorly. The point of the following is just that the details of God's 'character', His true 'nature,' are not important; what's important are the lives that people lead in His service. That's what I mean by a 'human mythology.' Christianity is a mythology for human beings to live inside, not a set of stories about superheroes. This is not an attack on the myth of a deity - there are plenty of those already.]
The 'character' of Yahweh is theologically and practically irrelevant. It's an interesting literary question (He is, after all, a literary creation!) but to occupy yourself with the 'true nature' of the Biblical God is to misunderstand its purpose. 'God' is to Christianity as vampires are to Buffy the Vampire Slayer: an inconsistently articulated metaphysical/metaphorical premise for a human mythology. The details can vary from week to week so long as emotional continuity and integrity are preserved. (Hence the meaninglessness of Biblical dietary prescriptions and sodomy laws.)
The story of Christ isn't a biography, it's an allegory - after all he didn't 'raise the dead,' nor did he 'turn water into wine.' As Jesus and early Christians reread Jewish myth/history as allegory, so the various Christian cults/churches reread Jesus as allegory.
One of the main characters on Buffy was given multiple birthdates; they don't conflict in any dramatically meaningful sense, so what difference does it make?
The only people who care about that stuff are fans; they are a blight on the body which would give itself over otherwise to ecstasy.
