One of the wonderful things about our modern Jewish world, is that in addition to the coming together of many Jewish ethnicities in Israel and other places, through the ease of modern communication we have a virtually unlimited supply of ways to engage in Jewish practice and we are no longer bound by only the customs of our direct line ancestors.
As a Reform Rabbi, I take a very pluralistic view of Judaism. Although American Jews are over 90% of European descent, there is nothing wrong with adopting a custom of a different Jewish culture. Certainly if we, as Jews living in a mostly non-Jewish culture, are willing to adopt practices like prayer and sermons in the vernacular, new liturgical music and a custom of giving presents at Chanukah, all of which are borrowed from our surrounding culture, it would be hypocritical of us to say that we can’t adopt customs of other Jews we find to be meaningful.
When adopting other customs, it is important to embrace those customs in a real and meaningful way, not just “playing Moroccan Jew” for an evening. That does not mean that one must accept all Moroccan Jewish customs, but taking seriously the ones you may adopt.
There is a long standing tradition to abide by the practices of our fathers, but this need not be followed blindly. The rituals and practices that gave great meaning to our parents, grandparents and others may feel rote and sterile to us. We could easily imagine the descendant of Moroccan Jews complaining about having to sit through “yet another” Mimouna and he would rather go get pizza to end Passover as has become a bit of an American Jewish custom. Therefore part of our role as seeking Jews is to find those customs and practices that speak to us and enhance our Jewish experience. When we do this, we find it gives value as well to those traditions handed to us by our own Jewish roots.
