The point I've been trying to make is that Christianity, in its Gnostic form, existed before Literalism, and the literalists are the only ones saying that the Jesus story is true, when it wasn't... so we can't date anything on a lie.
Jesus existed as a mythological character long before the Literalists got hold of him and tried to make him a historical figure. The name Jesus is an anglicised version of Iēsous, which is Greek for the Hebrew Yehoshua (Joshua), the same Joshua the led the 12 tribes to the Promised Land in the OT - this is the Jesus that the Essenes followed, the one that Justin Martyr called the Jesus of the Old Testament.
Remember this:
It is a waste of time searching in history for a mythological figure. We cannot attest anything from Mark when the whole work is a piece of fiction anyway, just like the rest of the Literalists' stories.
That's why the current timeline doesn't work - it's based on fiction. Once you go beyond it, you see that it was just an illusion. The teachings that Christianity were based on go back much further than 1 CE.
But anyway, I don't want to take up much more Grumpage's thread with this as we're going OT ... let's continue this in the Philo thread, if you still want to disagree with me.
