as an aside I had run across the letter mentioned while looking up another outright lie. I was researching Jesus in his misssing years and started down a trail of Jesus in Tibet and a supposed book which Jesus signed when he entered the monastery .... it turned out to be a red Herring and the whole missing years a snipe hunt. But that's for another topic.
I'd not heard that story before. I have heard of him in Egypt in his early life and I have heard of him traveling to India after another was crucified in his place.
I believe that was from the Second Treatise of Great Seth, one of the Nag Hammadi Scrolls (Dead Sea Scrolls)
It reads as follows;
“I did not succumb to them as they had planned… And I did not die in reality but in appearance, lest I be put to shame by them… For my death which they think happened [happened] to them in their error and blindness, since they nailed their man unto their death… It was another, their father, who drank the gall and the vinegar; it was not I. They struck me with the reed; it was another, Simon, who bore the cross on his shoulder. It was another upon whom they placed the crown of thorns… And I was laughing at their ignorance.”
The Koran seems toagree with the above;And for their unbelief, and their uttering against Mary a mighty calumny, and for their saying, ‘We slew the Messiah, Jesus son of Mary, the Messenger of God’…yet they did not slay him, neither crucified him, only a likeness of that was shown to them.
Just something interesting I thought I would share.
