Who is Jew ?

The answer is not so easy.
This thursday, november 30, 2006, at the SHUL of Surfside, the Rabbi Adin Steinsaltz was speaking about:" the Future Jew and the Jewish Future".
His proposal for this question was the most satisfaying I have heard at this time.
"The Jew is a person who will have jew grand children".

Et c'est tellement vrai.
