When Senator Bernie Sanders thanked supporters for his landslide victory in the New Hampshire Democratic primary, he wistfully reminisced about his upbringing as “the son of a Polish immigrant who came to this country speaking no English and having no money.”

While the crowd cheered, Rabbi Michael Paley of New York was among many Jews watching the speech who were taken aback. He said he was surprised that the Vermont senator had not explicitly described his father as a “Polish Jewish immigrant,” a significant distinction given Poland’s checkered history with its Jewish population.

“Nobody in Poland would have considered Bernie a Pole,” Rabbi Paley said.

Mr. Sanders, those who know him say, exemplifies a distinct strain of Jewish identity, a secular offshoot at least 150 years old whose adherents in the shtetls of Eastern Europe and the jostling streets of the Lower East Side were socialists, anarchists, radicals and union organizers focused less on observance than on economic justice and repairing a broken world. Indeed, he seems more comfortable speaking about Pope Francis, whose views on income inequality he admires, than about his own religious beliefs.

Rabbi Paley, who worked with Jews in central Vermont when he was a Dartmouth College chaplain, recalled once talking with Mr. Sanders about “non-Jewish Jews,” a term coined by a leftist biographer, Isaac Deutscher, to describe those who express Jewish values through their “solidarity with the persecuted.” Mr. Sanders seemed to acknowledge that the term described him, Rabbi Paley said.
