Nonsense, to be Jewish you have to believe and follow the OT, just as it is with a Christian who must Follow Jesus Christ.
The true Israelite is a born again Christian, because such serve the King of Israel.
Do you claim that the True worthy OT Israelites who came to know and followed their King Jesus Christ are called Jews ? no they are not Jews at all because they then became Christians in fact !
Fact is all within Christianity their is neater Jew or Gentile, did you know that fact.
Oh I am a Jewish Christian

? Oh I am a Budda Christian etc or I am a Black Christian etc or I am a American Christian or a Australian Christian ect ect, what a load of hogwash.
No ! one is a Christian first and foremost and nothing is added too.
Anyone who does not understand who Jesus Christ is and does not follow him is just some poor lost bastard who is not worthy regardless, the only thing one need understand is the OT Books are a blue print for the NT, so any so called Jew claiming out side of our OT books is in fact outside of God.
So anyone claiming to be a Jew that is not coming from the perspective of OT Books is a bastard, as to the OT, so any so called Jew who is following the Talmud Books is only worthy of Satan and not worthy to be called Israelite at all what soever, even back in the OT days.
The Talmud is a Whore and it has totally bastardised Judaism and is like a Pox on Christianity, that some so called Christians have turned from Christ Jesus to worship this Whore that is leading the whole world astray.
