Why We Observe Passover
Matthew B. Koss, a self-described "athiest Jew," writes to his daughter about why he observes Passover.
The answer to your question of why we are participating in this ritual when we don't go to temple even on Jewish holidays is that I want you to know the stories that this tribe told around their ancient campfires as they tried to make a better life. Even though our Passover Seder is quite irreverent, I want you to understand those stories from perspectives wider than the Red Sea. This was the Passover message that my father gave to me and that I understood to be that the real and best of Jewish tradition is to modify and improve the tradition. It is my gift to you that we go to your cousin's to observe this Passover Seder in our own way. That and we like the food.
