The title of the thread and youtube is misleading, it's not even the title of the documentary which is "Did Jesus Die". It was a while ago that I watched it but I don't recall it making any such claim that Jesus was an ordained member of the Buddhist Sangha, rather that he was influenced by contact with Buddhist teachers and this influenced his attempt to reform Judaism. The main point as far as I remember was to find a rational explanation for the disappearance of his body that doesn't buy into the usual myth.
