The problem with the whole idea of “affiliated” and “unaffiliated” is that it depends on an outdated model for Jewish community. The fact that young Jews are not affiliating in the old-fashioned way indicates there is something wrong with our institutions, not that there is something wrong with our youth. We have to let go of old ways of defining what it means to be an involved Jew and look to the kind of involvement that young Jews themselves seek. It takes some imagination to understand that the decline of Jewish institutions does not necessarily mean the decline of Judaism. Our question should not be “How can we get unaffiliated Jews to affiliate?” but “How can we inspire young Jews to understand Judaism as important for their own lives and for the world?” We should not be concerned with keeping Jewish institutions alive, but with keeping Judaism alive.
Simply because young Jews are not involved in the same way that their elders were does not mean that they are completely disengaged from Jewish life. While they may stay away from synagogues or Jewish Community Centers, they are clearly interested in Judaism. … They want to be Jewish, but on their own terms, as well they should.
