there has been a number of Jewish diasporas over the centuries, most notable the destruction of the temple in 70 AD and subsequent exile. A lot of time has passed and since then Hebrew has become a dead language since the 2nd century (now revived only a little over 100 years ago). Over this wide spread of people to distant lands, time and loss of identity is there really any such thing as a Jew today? or are we all Gentile?
