Introduction to Judaism

An Ancient Faith Rooted in Monotheism, Torah, and the Pursuit of Truth

Judaism is one of the world’s oldest monotheistic religions, founded upon the belief in one indivisible, eternal, and incorporeal God, the Creator of all existence. Its teachings emphasize ethical responsibility, justice, intellectual development, and living according to the commandments revealed in the Torah.

At the heart of Judaism stands the declaration:

שְׁמַע יִשְׂרָאֵל יְהוָה אֱלֹהֵינוּ יְהוָה אֶחָד

Shema Yisrael, Adonai Eloheinu, Adonai Echad.

“Hear, O Israel: The LORD is our God, the LORD is One.” — Deuteronomy 6:4

Judaism traces its spiritual origins to Abraham, who rejected the idolatry of his time and recognized the existence of one Creator. The Jewish people later entered into a national covenant with God at Mount Sinai, receiving the Torah through Moses as the foundation of their religious and moral obligations.

The Torah, consisting of the Five Books of Moses, forms the foundation of Jewish belief and practice. Its commandments govern both religious observance and everyday conduct, encompassing prayer, Shabbat, dietary laws, charity, justice, family relationships, and ethical treatment of others.

Throughout history, Jewish sages interpreted and applied these commandments, developing the legal tradition known as Halacha, preserved and discussed in works such as the Mishnah, Talmud, and subsequent codes of Jewish law.

From the philosophical perspective of Rabbi Moses Maimonides (1138–1204), one of Judaism’s greatest scholars, the purpose of religious life extends beyond ritual observance. Human beings are called to develop their intellect, acquire knowledge of God, cultivate moral character, and live according to wisdom and righteousness.

Maimonides emphasized that God possesses no physical form and is not subject to human limitations. He encouraged rational inquiry and opposed superstition and practices based upon unfounded supernatural claims.

Judaism also teaches that righteousness is not exclusive to Jews. While the Jewish people possess a unique covenant and particular religious obligations, non-Jews can live righteous lives and attain a share in the World to Come without converting. Those who sincerely wish to embrace Judaism may nevertheless enter the covenant through conversion and become full members of the Jewish people.

Unlike religious systems that emphasize salvation through belief alone, Judaism places significant importance on human actions, moral accountability, and the fulfillment of divine commandments.

At its core, Judaism is a way of life dedicated to knowing God, pursuing truth, practicing justice, and transforming religious understanding into ethical action.

Through the teachings of the Torah and the intellectual legacy of Maimonides, Judaism offers a comprehensive approach to life in which faith, reason, and moral responsibility work together in the service of the One God.
