In what way was Jesus Jewish? His mother Mary was an Israelite from the tribe of Levi, not Judah. At least two church Fathers thought his Name Jesus gk Iesous was Greek. He lived and worked in Galilee of the Gentiles. Spoke Greek, as did most people in Galilee. He called the Jews the 'Sons of Satan'. His cousin John the baptist was a Mandaean. Jesus was called a Nazarene, the Nazarenes were a Mandaean sect. I've seen Greeks claim that Jesus was Greek in the sense that he spoke Greek and in those days to speak Greek, was to be Greek.
First of all, sources please. Which Fathers? and where? Two Fathers does not a consensus make.
Secondly, suggesting that St. John the Baptist was a Mandaean is a bit of an anachronism, no? Unless you would follow the Mandaean's chronology and their claiming St. John for themselves, in which case, why not become a Mandaean?
To address your question, though, and overlooking the etymologically and historically muddled speculations appended to it: Yes, according to the Orthodox, Jesus Christ was most certainly Jewish, and not incidentally, but of necessity (as it were) and by design. Read the Gospels for starters. Off the top of my head: Luke 2:21-24 and what follows, also 2:41-49. John 2:13-17 & 4:19-22. Galatians 4:4-5. Romans 1:3.
However, you are under no compulsion to believe this, as you are apparently not Orthodox, and I am thinking doubtfully Christian, as attested by your continual reference to the most florid heretical delusions. So, for you, He can be whoever you want, I suppose: The Aryan Christ, The Gnostic Christ, The Mandaean Christ, The Muslim Christ, etc. At some point you will have to make up your mind whether to accept Him or some counterfeit version of Him. The choice is yours alone to make but it is not one to be taken lightly.
May God grant you wisdom.
