[SuziQ]

Yes, Jesus was Jewish. He was called 'Rabbi' by many of His followers, and he frequently taught in the Synagogues. He wouldn't have been able to do that, had he not been Jewish.

It is Jesus's followers who call themselves 'Christians'.

[1010RD]

Rabbi and teaching in synagogues are contextual to the time.

Do you believe Jesus is God, the Son of God or the Messiah?

That he died and was resurrected in payment of your sins?

Are these Jewish concepts?
