How do Christianity and Judaism fundamentally differ? 1. Definitions and Scope Christianity and Judaism share a historical connection through the Hebrew Scriptures (the Tanakh, corresponding to the Old Testament in Christian Bibles), tracing lineage back to Abraham, Isaac, and Jacob. However, they diverge in key doctrinal areas. This entry examines foundational distinctions in Scripture, beliefs about God, the role of Messiah, salvation, worship practices, and other important theological elements. 2. The Nature of God Christian teachings affirm the oneness of God while also proclaiming that the Father, the Son (Jesus Christ), and the Holy Spirit are distinct persons within the one eternal Divine Being (cf. Matthew 28:19). Judaism, in its mainstream forms, maintains that God is strictly one and does not accept any plurality of persons. Both traditions emphasize monotheism, but the Christian understanding of the Trinity sets it apart from most Jewish theology. 3. The Messiah and Jesus of Nazareth A central difference between these two faiths lies in the identity of the Messiah. Christianity professes that Jesus of Nazareth is the long-awaited Messiah (Greek: Christ) who fulfilled Old Testament prophecies (e.g., Isaiah 53; see also Luke 24:44). According to Christian belief, Jesus’ life, death, and resurrection are the ultimate culmination and fulfillment of all messianic predictions. In Judaism, while there are many messianic expectations, the majority position holds that the Messiah has not yet come. Traditional Jewish thought anticipates a future deliverer, a descendant of David, who will restore Israel and bring peace. Thus, the Christian conviction that the Messiah has already come in the person of Jesus sharply contrasts with continued Jewish expectation. 4. Scripture and Canon Both faiths revere the Hebrew Scriptures, yet they differ in canon and interpretive authority. For Christians, the canon includes both the Old Testament and the New Testament. The New Testament writings (e.g., the Gospels, Acts, Epistles, and Revelation) are foundational, teaching that Jesus fulfilled and clarified the Law and the Prophets (see Matthew 5:17). Judaism affirms the Tanakh (Torah, Nevi'im, and Ketuvim) as Scripture. Rabbinic tradition, expressed in writings such as the Mishnah and Talmud, further develops how the commandments should be observed and interpreted. In contrast, Christians look to the New Testament as the primary lens through which to understand the Hebrew Scriptures. 5. The Role of the Law (Torah) In Judaism, adherence to commandments found in the Torah (the first five books of the Hebrew Scriptures) remains paramount. Observant Jews keep dietary laws, Sabbath regulations, and other commandments as an ongoing covenant practice. Christians believe the Law reveals human sinfulness and points to the need for a Savior (Romans 3:20). They teach that Jesus fulfilled the Law, instituting a new covenant (cf. Hebrews 8:13). While moral truths endure, ritual obligations specific to Israel under the Mosaic covenant are generally seen as fulfilled in Christ, thus not binding upon Gentile believers (Galatians 3:23–25). 6. Salvation and Atonement Christian theology asserts that salvation is found in Christ’s sacrifice on the cross and His subsequent resurrection (Romans 10:9). The sacrificial system of the Old Testament is understood as pointing forward to the ultimate, once-for-all atoning death of Jesus (Hebrews 9:26–28). Faith in Christ’s redemptive work is therefore viewed as the sole basis for forgiveness and reconciliation with God. In Judaism, atonement historically involved animal sacrifices in the Temple, prayers of repentance (teshuvah), and righteous deeds. Since the Temple’s destruction in 70 AD, repentance, prayer, charity, and the observance of commandments are often identified as the means by which sins are atoned. Many Jewish teachings emphasize a continued role for prayer and virtuous behavior in communion with the living God. 7. The Resurrection of Jesus Christian beliefs focus on the bodily resurrection of Jesus as the pivotal event validating His claims (1 Corinthians 15:3–8). This miracle is historically attested in the earliest Christian writings. Christian apologists also point to extra-biblical references, such as the works of first-century historian Flavius Josephus (though debated in certain textual variants), in arguing for the historical reliability of Jesus’ crucifixion and the subsequent birth of the Christian movement. In Judaism, the resurrection of Jesus is typically not accepted. While some Jewish scholars acknowledge that a teacher named Jesus existed and was crucified, they do not affirm that He rose from the dead. The Christian proclamation of the resurrection thus creates a profound divergence between these faiths. 8. Fulfillment of Prophecy Christians claim that numerous Old Testament prophecies find specific fulfillment in Jesus’ life, death, and resurrection (e.g., Micah 5:2, Isaiah 9:6, Isaiah 53; see Matthew 1:22–23). Archaeological discoveries supporting the antiquity of the book of Isaiah—such as the Great Isaiah Scroll among the Dead Sea Scrolls—demonstrate that these messianic texts existed centuries before Jesus. Judaism, however, interprets many of those same passages differently, often viewing them collectively as referring to the nation of Israel’s sufferings or another future figure. Thus, the differences in interpretation of shared Scriptures remain substantial. 9. Worship and Religious Observance Christian worship centers on Christ as Lord, typically observing Sunday as the principal day of communal worship, commemorating His resurrection. There is also freedom among many Christian denominations to meet on other days, celebrate commemorations like Christmas and Easter, and practice baptism and the Lord’s Supper (Communion). Judaism practices weekly Sabbath observance from Friday evening to Saturday evening (Exodus 20:8–11). Feasts such as Passover, Yom Kippur, and Sukkot remain central to Jewish religious identity, with worship focused on the oneness of God. Synagogue gatherings include reading from the Torah and the Prophets, prayer services, and the singing of Psalms. 10. The Concept of a New Covenant Christian Scripture teaches that Christ established a new covenant promised in the Hebrew Scriptures (Jeremiah 31:31–34), making believers “a royal priesthood” (1 Peter 2:9) empowered by the Holy Spirit. This new covenant is understood as open to all nations (Matthew 28:19; Romans 1:16). Judaism largely does not embrace the idea that God has formed a new covenant that supersedes the Mosaic covenant. Instead, it emphasizes that the same covenant, given to the people of Israel, continues in force. The notion of a new, universal covenant that centers on the crucified and risen Messiah is absent from most Jewish teachings. 11. The Holy Spirit Christian tradition teaches that the Holy Spirit is the personal presence of God dwelling within believers, guiding them into truth (John 14:26) and empowering the church. The Holy Spirit’s indwelling is a defining aspect of Christian life, providing continual spiritual transformation and assurance of salvation (Ephesians 1:13–14). Judaism, while reverent toward the Spirit of God (Ruach HaKodesh), does not teach a co-equal person within the Godhead. Instead, references to God’s Spirit in the Hebrew Scriptures are typically regarded as expressions of God’s power and presence, without identifying Him as a distinct person. 12. The Expectation of the World to Come Christian doctrine upholds the promise of eternal life in the presence of God through Christ’s resurrection (John 11:25–26). The hope of believers is anchored in a bodily resurrection, a renewed creation, and unending fellowship with God. Many Christian confessions assert a final judgment (Revelation 20:11–15) followed by the eternal state. Judaism also teaches about a future resurrection and a Messianic Age, although beliefs can vary widely. Certain Jewish texts describe the world to come (Olam HaBa) in terms of reward for the righteous. However, a unifying acceptance of Jesus as the path to eternal life and the final judge is absent, which marks an important parting of ways. 13. Historical Evidence and Archaeological Support Scholars have long studied evidence supporting the biblical narrative. Findings like the Dead Sea Scrolls confirm the textual reliability of significant portions of the Hebrew Bible. Excavations in Israel, such as those at the City of David in Jerusalem, continue to uncover artifacts aligning with the history described in biblical texts. Christian apologists point to corroborations of Jesus’ life in Jewish (e.g., partial references in Josephus) and Roman sources (e.g., Tacitus, Pliny the Younger). While Judaism recognizes many of these historical texts, it does not draw the same theological conclusions about Jesus’ identity and work. 14. Summary of Key Differences • View of Jesus: Christians recognize Jesus as the Messiah and divine Son of God. Judaism rejects this claim. 15. Concluding Thoughts Christianity and Judaism share a common heritage yet diverge on critical theological questions. Central among these differences is Jesus’ identity and His work of redemption, supported by the New Testament and interpreted through centuries of Christian teaching. While both traditions honor the same Hebrew Scriptures, they part ways in their acceptance or rejection of the New Covenant and the Messiah’s arrival. Even with these significant distinctions, the historical and theological links between Christianity and Judaism remain compelling subjects for study. Both faiths affirm devotion to God, the importance of righteous living, and the centrality of Scripture for guidance. Yet, their fundamental differences—especially concerning Jesus—mark the clearest boundary distinguishing one tradition from the other. “‘For I delivered to you as of first importance what I also received: that Christ died for our sins according to the Scriptures, that He was buried, that He was raised on the third day according to the Scriptures…’” (1 Corinthians 15:3–4). |
