Introduction to Judaism

One God, One Covenant

At the heart of Judaism is a simple, powerful idea: there is only one God. This belief, known as monotheism, set the ancient Hebrews apart from neighboring cultures that worshipped many gods. For Jewish people, this single, all-powerful God is the creator of the universe and is involved in the world, yet remains transcendent and beyond full human comprehension.

Jewish people believe there’s only one God who has established a covenant—or special agreement—with them.

This special agreement is called a covenant. It began with a man named Abraham, who is considered the patriarch of the Jewish people. According to tradition, God made a promise to Abraham: if he and his descendants would worship God alone, God would make them a great nation and give them a special land. This covenant established a unique, lasting relationship between God and the Jewish people, built on mutual promises and responsibilities.

The Guiding Text

The foundational text of Judaism is the Torah. The word "Torah" means "teaching" or "guidance" in Hebrew. It refers specifically to the first five books of the Hebrew Bible, also known as the Five Books of Moses: Genesis, Exodus, Leviticus, Numbers, and Deuteronomy.

The Torah contains the history of the Jewish people from creation to the death of Moses. More importantly, it holds the laws and commandments that form the basis of Jewish life. It's not just a history book; it's a guide to living ethically and righteously, outlining how to create a just society and maintain the covenant with God. The Torah is central to Jewish prayer, study, and community life.

Branches of Judaism

While united by core beliefs, Judaism is not a single, uniform religion. Over time, different interpretations of Jewish law and tradition have led to the development of several major branches, or denominations. Each has a distinct approach to how Jewish life should be practiced in the modern world.

DenominationApproach to Jewish Law (Halakha)
OrthodoxBelieves the Torah and its laws are divine and unchanging. Adherence is considered binding.
ConservativeViews Jewish law as binding but also believes it should adapt to contemporary life.
ReformEmphasizes the ethical teachings of the tradition over strict observance of ritual law.
ReconstructionistSees Judaism as an evolving religious civilization. Traditions are valued but can be modified.

These denominations vary in their views on everything from synagogue services and gender roles to the importance of traditional dietary laws. This diversity allows Jewish people to find a community that aligns with their personal beliefs and level of observance.

Orthodox Judaism is the most traditional, holding that the laws from the Torah were given by God and cannot be changed. Conservative Judaism occupies a middle ground, seeking to preserve tradition while allowing for some evolution. Reform Judaism, the largest branch in the United States, prioritizes the ethical dimensions of the faith over ritual observance. Finally, Reconstructionism, the newest and smallest major movement, views Judaism as a culture and civilization that is constantly being recreated by the Jewish people.
