Imagine going to celebrate a hypothetical holiday with Martian relatives on their planet. You don't know the language, you don't know the customs, you don't know the purpose of the holiday. You might cope by seeing yourself as an anthropologist, witnessing the strange rites of the other. Still, even if you care deeply about your Martian family, the experience isn't going to feel familiar or personally meaningful. Yet if this is your own family, you might want to become more involved.
For non-Jewish partners, even with the best good will, the seder experience can be strange and unfamiliar. Jewish family members prioritize coming together at this time of year. Festive preparations have been made: There's a feast that includes ritual foods such as matzah and special items on a seder plate. There may be lots of Hebrew reading accompanying the meal. Or perhaps the family gathers but with no apparent religious themes. Each family's Passover is unique, yet there are some ways to orient and integrate non-Jewish guests and family members.
For one thing, some universal themes are celebrated at the seder. The greens and hard-boiled egg on the seder plate celebrate the renewal and rebirth of spring. The story of the exodus of the Hebrew slaves can be seen as a celebration of freedom and has become a paradigm of liberation for many peoples, including African American slaves and Tibetan Buddhists. Bringing alive these elements of the story can be an invitation to all people to be part of the celebration.
At some seders, people move beyond the traditional Passover text to have conversations applying the seder themes to their own lives. They see themselves as moving through bondage, liberation, wandering in the desert, and seeking the "promised land" in very personal ways and discuss how each guest feels enslaved or stuck in his or her life. They may say, metaphorically, as you cross the Red Sea, what do you want to leave behind? What do you want to take with you? In what ways can you identify with the Jewish people who wandered in the wilderness for forty years--where are you confused or questioning? What is the "promised land" for you? A new job? More time for yourself? Less clutter in the house?
If we make the Passover story our own we receive the gift of living within a myth that is larger than our individual selves. All people throughout history have experienced the tight, stuck places of mitzrayim (Egypt.) All people want liberation either from addictions, financial stress, health problems, or some other issue. The bigger story that we are part of helps normalize our own trials and tribulations. It gives meaning to the grand journey of life. And the big story is much more accessible to non-Jewish beloveds than the very specific rituals of the seder.
If you don't think all the members of your Passover gathering would want to focus on spiritual insights and sharing, maybe you and your spouse would want to prepare for Passover together by having these conversations. As the years go by, non-Jewish family members may learn to chant the four questions in Hebrew, spill drops of wine for each of the ten plagues and hide the middle matzah for the kids. But nothing will supersede the value of being invited to step into the mythic story of Passover as an insider and full participant.
