Jew - an individual who is a member of the Jewish People. The "Mission Statement" of that People is to be a "Kingdom of Priests and a Holy Nation."
The Question of "Who is a Jew?" has arisen with particular urgency today, especially in the modern State of Israel. This is because of intense pressure from the Movements of Reform and Conservative Jewry, who feel that they have been excluded or, more precisely, that Conversions performed by their Rabbis have not been recognized by Israeli authorities. Another major factor is the immigration of hundreds of thousands of individuals from the former Soviet Union, many of whom claim that they are Jews and who were in fact persecuted in their homeland because of that identification, but who may not, according to the Halachic definition (a definition according to Jewish Law) given below, be Jewish.
Thus, by birth or conversion, this individual has joined a family unique in the History of the World. Though very small in numbers, the family of the Jewish People is commanded to be a role model to the world, teaching that Man is a Servant, not to man but to G-d, in the sense that each individual must live their life according to the Commands of the Creator.
