For the record, I’m another atheist Jew. My mother’s family were assimilated German Jews who escaped Europe in 1941, and my American-born father came from a Protestant family, but was not religious in any way. Although my sister and I always knew we were Jewish by birth, there was no discussion of god or religion in the family, and we were not raised with any awareness of Jewish practice or traditions. It wasn’t until I had a Jewish friend in high school that I learned about things like keeping kosher.
Having had no religious indoctrination as a child, I always considered myself an atheist, once I knew what the word meant. As a young adult, after learning a little about the various major religions, I realized that Judaism was the only one I could have much respect for, mainly because it didn’t emphasize blind faith, but valued doubt, independent thought, and intellectualism. For most of my adult life I would tell people who asked that if I were forced to claim a religion it would be Judaism, not only because I was technically born into it, but because it is one of the few religions in which you can be an atheist. However, I never engaged in any Jewish practices other than occasionally attending friends’ seders. (I never had a bar mitzvah ceremony.)
About 12 years ago I became involved with a woman who, although not born Jewish, had had an Orthodox conversion at 22 and has now worked as a Jewish educator for 40 years. She is far more knowledgeable about Judaism than most people who were born Jewish. She is also an atheist.
When we met she was an observant Conservative, keeping kosher, observing the major holidays, lighting candles and saying the blessings at Shabbat dinner every week, etc. Through her I have learned a great deal more about the traditions and culture of Judaism, and have seen their value even for people who don’t believe in god.
We were married under a chuppah in a ceremony jointly officiated by my wife’s rabbi friend and my sister, a Unitarian minister.
I bake challah for dinner every Friday, we go to high holiday services (when there isn’t a global pandemic), and we attend seders with family and friends every year. I have built Sukkot in every house we’ve lived in (four different ones, now.) The tallit I wear at services is at least 70 years old and belonged to my great uncle Fritz, who with my grandmother’s sister, Anni, were the first members of our family to flee Germany in the 1930s.
I am an atheist. And a Jew.
