Humanistic Judaism to Conservative Judaism.

panentheistic U.S. Reform Jewish theology, which many would have viewed as
atheistic or having atheistic tendencies.
Liberal Jewish theology makes few
metaphysical claims and is thus compatible with
atheism on an
ontological level. The founder of
Reconstructionist Judaism,
Mordecai Kaplan, espoused a
naturalistic definition of God, and some proponents of post-
Holocaust theology have also eschewed the belief in a
personal god. The
Jewish philosopher Howard Wettstein has advanced a non-metaphysical approach to religious commitment, according to which metaphysical theism-atheism is not the issue.

trained in the Reconstructionist tradition, has argued that Jewish theology should move from a focus on God to an emphasis on "godliness". This "predicate theology", while continuing to use theistic language, makes few metaphysical claims that non-believers would find objectionable.
Jewish culture
Many Jewish atheists reject even this level of ritualized and symbolic identification, instead embracing a thoroughgoing secularism and basing their Jewishness entirely in ethnicity and
secular Jewish culture. Possibilities for secular Jewishness include identification with Jewish history and
peoplehood, immersion in Jewish literature (including such non-religious Jewish authors as
Philip Roth and
Amos Oz), consumption of
Jewish food, use of
Jewish humor, and attachment to Jewish languages such as

Ladino. A high proportion of Israeli Jews consider themselves secular, rejecting some religious practices (see
Religion in Israel). While some non-believers of Jewish ancestry do not consider themselves Jews, preferring to define themselves solely as atheists, others believe Judaism is a culture and tradition that can be embraced without religious faith.
Many Jewish atheists continue to observe Jewish traditions, holidays, and customs, but view them more as cultural heritage than religious obligations. For example, celebrating
Hanukkah or
Passover can be seen as an important family and cultural ritual rather than a religious act. In the documentary series ''
Еврейское счастье'' (''Jewish Happiness''), alongside exploring other aspects, the question "Who is a Jew?" is extensively discussed. In one episode, a family of atheists deeply engages in certain Jewish religious traditions, such as
Shabbat, which, one of the documentary's characters asserts, has come to us as a tradition from ancient times but fits very well into contemporary reality. Specifically, it provides the opportunity to spend a whole day communicating with one's children, free from pervasive modern issues like
phubbing and
FOMO.
Some Jewish atheists are active in secular and humanist movements that advocate separation of church and state, human rights, and a scientific worldview.

The contradictory symbiosis between religiosity and atheism among atheists in the Jewish context has ambivalent qualities and is discussed extensively in ''The Cambridge Companion to Atheism'', as is how Jewish thinkers deal with these dynamics. This nuanced connection is also evident in other prominent Jewish atheists who maintained their cultural identity. The text discusses how the concept of religion developed in a Judeo-Christian context can be incorrect when applied outside that context. But careful application of these concepts can shed light on the unique perspectives of Jewish atheists who still value their cultural heritage. In Freud's ''
The Future of an Illusion'', he eschews religious belief and outlines its origins and prospects. But Freud also urged a Jewish colleague to raise his son in the Jewish religion, saying, Other researchers have written about Freud's views on religion and Jewish identity.

", but this was not atheism in the modern sense.
In the 19th and 20th centuries, many Jews embraced secular and socialist ideals. Particularly in the Soviet Union and other Eastern European countries, many Jews became atheists under the influence of communist ideology.
Confirming the diverse history of Jewish atheism, reflecting a wide range of views and approaches to faith and identity, a blog entry by Vladimir Minkov on the ''
Times of Israel'' portal notes that a significant portion of modern U.S. Jews identify themselves as atheists or agnostics. Minkov argues that this is due to various factors, including lack of deep understanding of Jewish religious teachings and desire to find a Jewish identity outside traditional religious frameworks. Some interviews with Jewish atheists show that many of them continue to observe Jewish traditions and participate in cultural activities despite renouncing their religious beliefs. This demonstrates ambivalence when cultural-ethnic identity and a certain religiosity are preserved even in the absence of faith in God. Thus atheism among Jews is not only widespread but multifaceted, providing rich material for research and discussion on the topic of faith and identity in the Jewish context and making atheism among Jews an interesting subject for interdisciplinary research.
