Thanks for that pic, Leolaia. There's an interesting theory. It isn't the first one I've come across, either. I'd like to see some more posts and links from people who know what they're talking about. I find the ideas fascinating.
But it is quite evident that Jesus grew up in a Jewish household and followed the Mosaic law of his day. His knowledge of the Jewish beliefs, good and bad, is easily read in the New Testament.
We know he was born and raised a Jew. This thread is about his teens and twenties. It is possible to know about more than one belief system and culture, especially if you're the Son of God with more than a dozen years on your hands.
The lack of eastern influence is also quite clear.
No it isn't. Quite the contrary. Jesus' philosophy is quite eastern sounding to me and to many acquainted with both, even though he put it in a Jewish context for his audience. To some, he blatantly ripped off the eastern philosophers. To others, he borrowed the wisdom he felt the Jews and the Christians who would follow him needed. To still others, he was completely original even though he said things that had been written hundreds of years earlier, sometimes near-verbatim.
I have asked for evidence and you gave baseless assertions. "Evidently" doesn't cut it with an ex-JW like me.
