““To sum up, then, we are Israelites, descended from the small nation which came out of the Sinai desert into Canaan three thousand years ago, with a tradition of liberation from Egypt, under a lawgiver and deliverer named Moses. We are called Jews, and our heritage Judaism, because in the political decline and fall of our nation the tribe which held out longest and became the surviving remnant in exile predicted by the Torah was named Judah. Almost all living Jews stem, at a remove of no more than four or five generations at the most, from observant Jews. Historically, Israelites who have discontinued the practice of the law of Moses have faded into the environment and lost their identity within a century or two. The attrition over the centuries has of course been enormous. The Jews who are left are mainly the sons and grandsons of those who have kept the faith, preserving the chain unbroken through time, from the twentieth century back to the sunrise of the human intelligence. Before examining this faith, we can surely acknowledge two things: first, that as a feat of gallantry of the spirit of man, the preservation of Judaism ranks high; second, that if ancient lineage be a source of legitimate pride, the Jews have a right to be a proud people.””
