Our congregation considered the Jews at a nearby Reform synagogue to be almost as bad as the Goyim (Gentiles) because they not only failed to observe many of the Jewish rituals, but also conducted their services in English instead of Hebrew. Had I understood the English version of all my ritual Hebrew prayers, I’d undoubtedly have become an atheist even sooner. Eventually I stopped performing the rituals and moved from being an Orthodox Jewish atheist to just a Jewish atheist, without passing through Conservative or Reform branches.
Now when I give public talks, I’m invariably asked how a person can be both Jewish and an atheist. But “Jewish atheist” is not an oxymoron, as indicated by the subtitle of my book, “Jewish Atheist in the Bible Belt.” Since Jewish law is based on matrilineal decent, even Orthodox Jews consider an atheist born to a Jewish mother as fully Jewish. Consequently, one can be a religious, cultural, or ethnic Jew.
Within traditional Judaism, there is little interest in what one believes compared to what one does. Fixed prayers are standardized and required for the entire Jewish community, regardless of God belief. Saying these community prayers is not assumed to be an individual declaration of faith. There are 613 Torah commandments, and Orthodox Jews try to follow as many as possible. Some, like performing a ritual animal sacrifice at a temple in Jerusalem that no longer exists, are impossible. A commandment to believe in God is also impossible because people can’t will themselves to believe something they have solid reasons for not believing.
