What is Judaism? Beliefs, Traditions, and Key Teachings

Judaism, one of the world’s oldest monotheistic religions, traces its roots back thousands of years. It centers around the belief in a single, all-powerful God, a tradition that has profoundly influenced the religious, cultural, and ethical life of millions. Judaism emerged in the ancient Near East, evolving over centuries from the stories, teachings, and practices of the Jewish people, who believed they were chosen by God to uphold divine law. The religion’s teachings are deeply intertwined with the history of the Jewish people, and its sacred texts provide guidance on spiritual matters, ethics, law, and personal conduct. These texts, along with the experiences of the Jewish community over millennia, have shaped a complex tradition that remains vital to this day.

Judaism holds that God, who is both the creator and moral authority, made a covenant with the ancestors of the Jewish people—Abraham, Isaac, and Jacob. This covenant established the Jewish people as God’s chosen ones, tasked with following divine laws and principles that would bring blessings not only upon themselves but, ultimately, upon all of humanity. Central to Judaism’s teachings is the concept of ethical monotheism, which emphasizes a personal relationship with God, who is both just and compassionate. Jewish teachings advocate justice, mercy, humility, and love of others, stressing that faith in God must be accompanied by moral conduct.

Jewish beliefs are codified in a range of sacred texts. Foremost among these is the Torah, the first five books of the Hebrew Bible, which recounts the origins of the Jewish people and outlines the laws and commandments that God gave them. Alongside the Torah is the Talmud, a compilation of rabbinical discussions and interpretations that offer insights into Jewish law, ethics, customs, and history. The Torah and Talmud together form the basis of halakhah, or Jewish law, which guides not only religious practices but also aspects of daily life, including diet, dress, social interactions, and business ethics. Halakhah is seen as a means of sanctifying the everyday, turning mundane activities into opportunities to fulfill divine will.

The core beliefs in Judaism encompass a wide array of theological and ethical tenets. Fundamental among these is the Shema, a declaration of faith that proclaims the unity of God and the call to love God wholeheartedly. The Shema, which begins with the words “Hear, O Israel: The Lord our God, the Lord is one,” encapsulates Judaism’s commitment to monotheism. Another central belief is the concept of mitzvot, or commandments. There are 613 mitzvot found in the Torah, encompassing religious obligations and ethical directives. These commandments cover every aspect of life, guiding Jews in their relationship with God and with others.

Judaism teaches that God is omnipotent, omniscient, and omnipresent, qualities that signify God’s supreme authority and presence in the universe. However, God is also portrayed as compassionate and merciful, engaging in a relationship with humanity and offering opportunities for forgiveness and redemption. This dual aspect of justice and mercy forms the basis of Jewish ethics. The tradition of teshuvah, or repentance, allows individuals to seek forgiveness from God and make amends for wrongdoings, emphasizing personal responsibility and the potential for spiritual growth.

Another significant tenet of Judaism is the belief in a Messiah, a future leader who will bring peace and justice to the world. Though interpretations vary among Jewish groups, the concept of the Messiah traditionally envisions a descendant of King David who will restore Israel, establish a kingdom of righteousness, and bring all nations to worship the one true God. This belief in the coming of the Messiah is closely related to the Jewish understanding of the future redemption of humanity and the ultimate fulfillment of God’s promises.

Jewish tradition is rich with rituals, festivals, and observances that reflect the rhythm of the Jewish calendar and the stages of life. Among these are the High Holy Days, including Rosh Hashanah, the Jewish New Year, and Yom Kippur, the Day of Atonement. Rosh Hashanah is a time of introspection and prayer, marking the beginning of a ten-day period known as the Days of Awe, when Jews reflect on their actions over the past year. Yom Kippur, which concludes this period, is a day of fasting, prayer, and repentance, dedicated to seeking forgiveness from God and others.

The weekly observance of Shabbat, or the Sabbath, is one of the most distinctive aspects of Jewish practice. Shabbat, which begins at sundown on Friday and ends at nightfall on Saturday, is a day of rest and spiritual renewal, recalling the biblical account of creation when God rested on the seventh day. Observing Shabbat involves abstaining from work, spending time with family and community, attending synagogue services, and engaging in prayer, study, and reflection. Shabbat serves as a reminder of God’s role as the creator and sustainer of the world and provides a time for individuals to reconnect with their faith.

Jewish dietary laws, known as kashrut, outline which foods are permissible to eat and how they must be prepared. These laws, derived from biblical commandments, prohibit certain foods, such as pork and shellfish, and require that meat and dairy products be kept separate. Foods that comply with these laws are considered kosher. Observing kashrut is seen as a way to uphold Jewish identity and maintain a sense of discipline and mindfulness in everyday life. Beyond dietary laws, other commandments govern personal behavior, promoting honesty, kindness, and respect for others.

Judaism emphasizes the importance of learning and study, particularly of the Torah and other sacred texts. The study of Torah is considered a lifelong pursuit, essential for understanding God’s will and deepening one’s faith. Jewish communities have long maintained institutions of learning, from traditional yeshivas to modern schools and universities, fostering a commitment to education and intellectual inquiry. This dedication to study reflects a belief that knowledge and wisdom are central to living a righteous life and fulfilling one’s religious obligations.

Prayer holds a central place in Jewish worship and is seen as a means of connecting with God, expressing gratitude, and seeking guidance. Daily prayers are structured into three services—Shacharit (morning), Mincha (afternoon), and Maariv (evening)—each with its specific themes and liturgical texts. The Amidah, a series of blessings and petitions, is a key component of these services, covering requests for healing, peace, forgiveness, and other essential needs. Jewish prayer is both communal and personal, allowing for a shared experience of worship while also providing space for individual reflection and devotion.

Jewish festivals celebrate historical events, agricultural cycles, and religious themes, reinforcing the values and identity of the Jewish people. Passover commemorates the Exodus from Egypt, when God delivered the Israelites from slavery, while Shavuot celebrates the giving of the Torah at Mount Sinai. Sukkot, the Feast of Tabernacles, recalls the Israelites’ journey through the wilderness and emphasizes themes of gratitude and dependence on God. Each festival has its unique customs, foods, and rituals, creating a cyclical pattern of remembrance and renewal throughout the year.

Judaism has a strong ethical dimension, rooted in the belief that humans are created in the image of God and, therefore, bear a moral responsibility toward others. This ethic is encapsulated in the concept of tikkun olam, or “repairing the world,” which encourages Jews to work toward social justice, environmental stewardship, and peace. Acts of charity, or tzedakah, are considered a religious duty, not merely an expression of goodwill, reflecting the Jewish commitment to fairness and compassion. The practice of tzedakah includes giving to the needy, supporting communal institutions, and promoting social welfare, underscoring the importance of caring for others.

Jewish law and tradition provide guidance on life’s major milestones, from birth and marriage to death and mourning. Circumcision, performed on the eighth day of a boy’s life, marks the covenant between God and the Jewish people. Bar and Bat Mitzvah ceremonies, held at age thirteen for boys and twelve for girls, signify the assumption of religious responsibilities. Marriage is seen as a sacred covenant, and the Jewish wedding ceremony includes various symbolic elements, such as the breaking of a glass to remember the destruction of the Temple in Jerusalem. The Jewish mourning practices, including the recitation of the Kaddish prayer, reflect respect for the deceased and provide support for those grieving.

The Holocaust, one of the darkest chapters in Jewish history, profoundly affected Jewish identity and faith, leading to reflections on human suffering, divine justice, and resilience. For many Jews, the memory of the Holocaust reinforces a commitment to remember the past, protect the vulnerable, and prevent future injustices. The establishment of the modern State of Israel, regarded by some as the fulfillment of biblical prophecies, has also shaped Jewish identity and raised theological and political questions about the relationship between faith and nationhood.

Jewish beliefs and practices vary among different branches of Judaism, including Orthodox, Conservative, Reform, and Reconstructionist movements. Orthodox Judaism adheres closely to traditional interpretations of Jewish law, emphasizing strict observance of commandments and ritual practices. Conservative Judaism seeks to preserve core aspects of Jewish law while adapting certain practices to modern circumstances. Reform Judaism promotes greater individual autonomy in religious observance, often interpreting Jewish teachings in a more progressive light. Reconstructionist Judaism views Judaism as an evolving cultural and religious civilization, emphasizing community, ethics, and cultural heritage.

Throughout its history, Judaism has contributed significantly to the development of Western ethical thought, legal principles, and spiritual ideals. The emphasis on justice, compassion, and the dignity of every individual has influenced not only Jewish communities but also broader societies. Today, Judaism continues to inspire adherents and non-adherents alike, offering a vision of a world rooted in compassion, learning, and the pursuit of justice. As Jewish communities around the world preserve their traditions and adapt to contemporary challenges, Judaism remains a vibrant and enduring source of faith, identity, and moral guidance.
