The definition of Jew at the time was compatible with believing Jesus is the Messiah and the Son of God. He was and still is a Jew, despite later Jews going astray and rejecting him.

Well, nowadays at least, if you're mother is Jewish, then you're Jewish. So by that standard, Jesus was definitely a Jew.

The reality though is that "Judaism" is yiddish nonsense and Jesus was a Hebrew.

modulo any syntax errors this is the recursive definition of isAJew

// JEWISHNESS PROPERTY TRANSMITTED VIA MATERNAL

// NOT PATRIARCHAL LINE

boolean isAJew( Person p ) { if ( p.mother == SARAH ) || isAJew( p.mother ) );

  return true;

return false; }
