I think the words to hold to hear Cordoba here are the words of Jesus himself when he met the Magdalen regarding what occured to him, to which he said 'I have been Jonah in the Belly of the Whale'. The 'Judas Theory' is an old one, and does not rest on this new gospel, it is considered to be written even in the four gospels in the NT. I have briefly outlined in here in other places but will post it again. I have not looked up the specific points, tho I did many years ago, and the standard gospels while not conforming the theory certainly neither disprove it either.
This is paraphrased as I can't bothered with chapter and verse, a well versed Christian will know the relevant parts immediately. Jesus was not an only child, first born of Mary, yes, only child no. Jesus' brothers (James and some have it Judas, tho' Judas may have been a cousin) travelled with him during his ministry. Things get a little hairy and the hierarchy in Jerusalem have it in for Jesus, so a counter plan is formed using a double. When the heat get's too much the Temple guards are lead to Judas the daggerman (read bodyguard, lit. Sicarii) in [SIZE=-1]Garden of Gethsemane, who is kissed as thanks. Judas is 'hung from a tree', but does not die (i.e. spear of destiny already mentioned), he is brought down and reappears called brother (literally or figuratively depending what you believe), which gives us the character Thomas (lit. brother) formally known as Judas. Jesus meanwhile is as Jonah in the belly of the whale.[/SIZE]
The gospel of Judas, according to 'wiki' has a very interesting quote,
"Step away from the others and I shall tell you the mysteries of the kingdom," and later "Look, you have been told everything. Lift up your eyes and look at the cloud and the light within it and the stars surrounding it. The star that leads the way is your star."
which in light of the semiotic construction of the very name of Jeheshuah (delineated elsewhere but can be posted here if anyone is interested) and with 666 often thought to represent the sun and thus solar rites and by implication the resurrection, it makes sense of the axiom 'Not risen as a Sun, risen as a star behind a cross'...
