Being an Atheist and Being Jewish - A problem?

Being an Atheist and Being Jewish - A problem?

Not really. Here is why:
Judaism emphasizes "belief" to a much lesser extent than other religions. Jewish Atheists are actually quite common. (see for instance this site). Questioning faith is not a "threat" to Judaism. In Fact, our name, Israel, means "struggle with God".

Judaism is more about your actions than what is in your heart. The old expression "creed versus deed" comes to mind. Many forms of Christianity emphasize faith and belief as central concepts. Creed guides them, while Judaism encourages you to do.

Here is an example:

This is lifted from the information from COEJL, Coalition on the Environment and Jewish Life. Visit them here.:

PROTECTING THE ENVIRONMENT IS A MITZVAH!

Protecting human health and the diversity of life is a value emphasized in Torah, Talmud, and rabbinic literature throughout the ages—beginning with the commandment in Genesis for Adam and Eve to serve and protect the Garden of Eden.

I’m Jewish—why haven’t I ever heard about a connection between Judaism and the environment?

Many Jews haven’t. Despite the richness of Jewish teachings related to our responsibility to protect the environment, few Jews have been introduced to them.

COEJL seeks to expand the contemporary understanding of such Jewish values as tikkun olam (repairing the world) and tzedek (justice) to include the protection of both people and other species from environmental degradation.
