Judaism is an ancient monotheistic faith with roots in the ancient Near East. The name in Hebrew is often given as יהדות; its adherents are commonly called Jews. Though estimates vary, the global Jewish population is on the order of tens of millions. Judaism is widely recognized as the earliest of the Abrahamic religions and is defined by its belief in a single, indivisible God, ethical commandments, and a historical covenant between God and the people of Israel. This basic theological stance is often described as monotheism.

Central to Jewish religious life is the Torah, traditionally the first five books of the Bible. Together with the wider collection known as the Hebrew Bible (sometimes referred to in interfaith contexts as the Old Testament), the Torah provides foundational narratives and commandments. Beyond the written law, Judaism emphasizes oral explanations and legal reasoning that were compiled in works such as the Talmud and the Mishnah. Jewish religious life balances scripture, legal interpretation, ethical teaching, and communal norms often summarized as the laws of the tradition.

Beliefs, rituals and communal life

Jewish practice includes a range of rituals, life-cycle events, and communal observances that mark identity and religious obligation. Common elements include synagogue prayer, observance of the Sabbath (Shabbat), dietary laws (kashrut), circumcision (brit milah), and festivals such as Passover, Rosh Hashanah, Yom Kippur and Sukkot. Religious life varies widely by community; some Jews place primary emphasis on study and observance, while others emphasize cultural or ethical aspects.

Key characteristics

  • Scriptural and legal core: Torah and rabbinic interpretation.
  • Ethical monotheism: a commitment to justice and communal responsibility.
  • Communal institutions: synagogues, schools, and communal charities.
  • Lifecycle rites: birth, coming-of-age, marriage, bereavement practices.

History and development

Judaism developed over many centuries in the ancient Levant and evolved through periods of monarchy, prophetic leadership, foreign domination, and diaspora. Rabbinic Judaism, which became the dominant form after the destruction of the Second Temple in 70 CE, emphasized study, prayer, and the law as vehicles for preserving identity outside a central temple. Over time Jewish communities spread across Europe, North Africa, the Middle East, and later the Americas and other regions, creating diverse local customs while sharing core texts and beliefs.

Denominations and modern life

In the modern era, Jewish religious life is commonly categorized into streams such as Orthodox, Conservative, Reform, and other movements, differing in interpretation of law, liturgy, and engagement with modernity. Many Jews also identify culturally or ethnically rather than primarily religiously. Contemporary issues include communal pluralism, secularism, and the relationship between religion and the state in places with significant Jewish populations.

Relations to other faiths and notable distinctions

Judaism shares historical and theological connections with both Christianity and Islam; all three trace aspects of their heritage to the patriarch Abraham and share some scriptural material and ethical teachings. However, Judaism is distinct in its emphasis on the covenant, the primacy of the Torah and rabbinic interpretation, and particular ritual laws. Its long history and textual tradition have made it a major influence on Western religious, legal, and ethical thought.
