There is no more nettlesome minefield in the Jewish domain than the idea that we are ''a chosen people.'' The idea is not merely politically incorrect - as even those who think it theologically correct must realize - it is embarrassing. Theology aside though, chosenness grants the Jewish people their unique character and individuality. The delights of difference come together with the dilemmas and the sometime discord of difference. But it is a gift that should be cherished, not relinquished to history.
