Judaism is the religion, culture, and covenant identity of the Jewish people. It begins with God’s call of Abraham, is shaped by the Torah given through Moses, and develops through Israel’s history, prophets, temple worship, exile, restoration, and Second Temple life.

At its core, Judaism is monotheistic — the worship of the one true God:

“Hear, O Israel: The LORD our God is one LORD.” ()

This verse, known as the Shema, is the foundational confession of Judaism.

Foundations of Judaism

Judaism is built on several pillars:

  • Covenant — God’s promises to Abraham, Isaac, and Jacob
  • Torah — God’s instruction for life, worship, and holiness
  • Temple — the center of sacrifice and God’s dwelling
  • Prophets — calling Israel back to covenant faithfulness
  • Writings — wisdom, worship, and reflection on God’s ways

The Torah establishes Israel’s identity as God’s chosen people:

“Ye shall be unto me a kingdom of priests, and an holy nation.” ()

Judaism in the Second Temple Period

By the time of Jesus, Judaism had developed distinct groups:

  • Pharisees — emphasized oral tradition and strict observance
  • Sadducees — priestly class tied to the Temple, rejected resurrection
  • Essenes — separatist, purity‑focused communities
  • Zealots — political revolutionaries

These groups shaped the religious landscape Jesus interacted with.

Judaism and Jesus

Jesus was born, raised, and lived as a Jew. His teachings are rooted in the Torah, and He affirms its authority:

“I am not come to destroy the law… but to fulfil.” ()

When asked about the Greatest Commandment, Jesus quotes directly from Judaism’s core texts:

  • Love God —
  • Love your neighbor —

Jesus’ debates with Pharisees and Sadducees are internal Jewish discussions about the meaning of Torah, resurrection, authority, and the kingdom of God.

Judaism after the Temple’s Destruction

In AD 70, Rome destroyed Jerusalem and the Temple — fulfilling Jesus’ prophecy (). Without the sacrificial system, Judaism transformed into Rabbinic Judaism, centered on:

  • Torah study
  • Synagogue worship
  • Prayer
  • Halakhah (Jewish law)

This form of Judaism continues today.

Theological Significance

Judaism represents:

  • God’s covenant with Israel
  • The foundation of biblical revelation
  • The context of Jesus’ life and ministry
  • The root from which Christianity emerges
  • The ongoing story of God’s people in history

Because Judaism embodies covenant identity, monotheism, Torah, and prophetic tradition, it naturally highlights several core realities:

  • Faith of Israel rooted in the Torah
  • Confession of one God ()
  • Covenant identity as God’s chosen people ()
  • Shaped by Temple worship and prophetic revelation
  • Includes Pharisees, Sadducees, Essenes, Zealots in Jesus’ day
  • Transformed into Rabbinic Judaism after AD 70
  • Provides the religious context of Jesus and the early church
