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.
Today, however, in our era of spiritual displacement, there exists a fifth child: 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.
