As different as they may be, the four sons of the Haggadah have one thing in common: whether involved, challenging, inept or indifferent, they are all present at the  seder  table. They are all relating, albeit in vastly differing ways, to our annual reliving of the Exodus and our birth as a nation. The line of communication is open; the potential wise son that resides within every Jewish child is approachable.

According to the Lubavitcher Rebbe, however, in our era of spiritual displacement, there also exists a fifth son: the Jew who is absent from the  seder  table. He asks no questions, poses no challenges, displays no interest. For he knows nothing of the  seder , nothing of the significance of the Exodus, nothing of the revelation at Sinai at which we assumed our mission and role as Jews.

To these children of G-d we must devote ourselves long before the first night of Passover. We must not forget a single Jewish child; we must invest all our energies and resources to bringing every last fifth son to the  seder -table of Jewish life.
