How does Christianity differ from Judaism?
While sharing significant common ground as Abrahamic faiths rooted in the Old Testament, Christianity and Judaism diverge fundamentally on a central figure: Jesus of Nazareth. Both traditions affirm one God, the authority of the Hebrew Scriptures, and a covenant relationship between God and humanity. However, Christians believe Jesus is the promised Messiah, the Son of God, and the divine-human Savior whose death and resurrection offer salvation, a concept not accepted in Judaism. This core difference impacts understanding of atonement, law, and the nature of God's ongoing work in the world.
Christianity and Judaism differ primarily in their understanding of Jesus: Christians believe he is the Messiah and Son of God, while Judaism does not.
The Messiah
The most prominent difference between Christianity and Judaism centers on the Messiah. Judaism, while awaiting the Messiah, does not recognize Jesus of Nazareth as that promised deliverer. Jewish tradition typically envisions a human Messiah who will restore the Davidic kingdom, rebuild the Temple, and usher in an era of peace and universal knowledge of God, as prophesied in passages like Isaiah 11:1-9 and Zechariah 14:9. This Messiah will be a political and spiritual leader, but not divine.
Christians, conversely, believe Jesus is the Christ (from the Greek Christos meaning “anointed one,” equivalent to the Hebrew Messiah). The New Testament presents Jesus as the fulfillment of Old Testament prophecy, not only as a king but also as a suffering servant (Isaiah 53:1-12) and divine Son of God (John 1:1-14; Philippians 2:5-11). His first coming inaugurated God's kingdom spiritually, with a future second coming to fully establish it in power and glory (Matthew 24:30-31; Revelation 19:11-16).
The Law and Covenant
Both faiths uphold the Torah (God's Law as given to Moses) as divinely inspired. For traditional Judaism, the 613 commandments of the Torah are still binding, serving as the path to righteousness and a way of life that expresses covenant faithfulness. Observance of these laws—including dietary laws (kosher), Sabbath observance, and ritual purity—is central to Jewish identity and practice. While there are different streams within Judaism regarding the application and interpretation of these laws, their foundational importance remains.
Christianity affirms the Old Testament Law as God's righteous standard and a revelation of His character (Romans 7:12). However, Christians believe that Jesus fulfilled the Law (Matthew 5:17) and established a New Covenant (Jeremiah 31:31-34; Hebrews 8:6-13) through his atoning sacrifice. Under this New Covenant, salvation is received by grace through faith in Jesus Christ, not by works of the Law (Ephesians 2:8-9; Romans 3:20-28; Galatians 2:16). While the moral principles of the Law remain relevant (e.g., the Ten Commandments as ethical guidelines), the ceremonial and civil aspects are seen as fulfilled in Christ and no longer binding for believers. This is why Christians generally do not observe kosher laws or ritual sacrifices.
Salvation and Atonement
Judaism emphasizes atonement through repentance (Hebrew: teshuvah), prayer, and good deeds, especially during the High Holy Days like Yom Kippur. While the Temple stood, animal sacrifices were central to atonement for sin (Leviticus 16:1-34). Since the destruction of the Second Temple, prayer, fasting, and charity have largely replaced sacrificial rituals as means of seeking forgiveness and reconciliation with God. There is a strong emphasis on personal responsibility and God's mercy.
Christianity teaches that humanity is inherently sinful and cannot achieve righteousness through self-effort or religious observance alone (Romans 3:23; Isaiah 64:6). Therefore, God provided the ultimate atonement through the sacrificial death of Jesus Christ on the cross (Romans 5:8; 1 Peter 2:24). Christians believe Jesus, being sinless, bore the penalty for humanity's sins, satisfying divine justice. His resurrection signifies victory over sin and death, offering eternal life to all who believe in him (Romans 6:23; John 3:16). Atonement is thus a one-time, complete act by God through Christ, accessed by faith.
Nature of God
Both traditions are monotheistic, affirming one God as the Creator and Sustainer of the universe (Deuteronomy 6:4). However, Christianity introduces the doctrine of the Trinity: that God exists as three co-equal persons—Father, Son (Jesus), and Holy Spirit—yet is one God. This understanding is based on various New Testament texts depicting Jesus and the Holy Spirit as divine while affirming monotheism (Matthew 28:19; 2 Corinthians 13:14; John 10:30).
Judaism considers the Christian doctrine of the Trinity to be a fundamental departure from monotheism, viewing it as a compromise of God's absolute oneness. In Jewish thought, God is an indivisible unity, and the idea of a divine Son or Spirit as distinct persons within the Godhead is not accepted. Biblical passages like the Shema (Deuteronomy 6:4,
Bible verses about christianity vs judaism
"Think not that I came to destroy the law or the prophets: I came not to destroy, but to fulfil."
"for by grace have ye been saved through faith; and that not of yourselves, it is the gift of God; not of works, that no man should glory."
"for all have sinned, and fall short of the glory of God;"
"But God commendeth his own love toward us, in that, while we were yet sinners, Christ died for us."
"In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made through him; and without him was not anything made that hath been made. In him was life; and the life was the light of men. And the light shineth in the darkness; and the darkness apprehended it not. There came a man, sent from God, whose name was John. The same came for witness, that he might bear witness of the light, that all might believe through him. He was not the light, but came that he might bear witness of the light. There was the true light, even the light which lighteth every man, coming into the world. He was in the world, and the world was made through him, and the world knew him not. He came unto his own, and they that were his own received him not. But as many as received him, to them gave he the right to become children of God, even to them that believe on his name: who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. And the Word became flesh, and dwelt among us (and we beheld his glory, glory as of the only begotten from the Father), full of grace and truth."
"Have this mind in you, which was also in Christ Jesus: who, existing in the form of God, counted not the being on an equality with God a thing to be grasped, but emptied himself, taking the form of a servant, being made in the likeness of men; and being found in fashion as a man, he humbled himself, becoming obedient even unto death, yea, the death of the cross. Wherefore also God highly exalted him, and gave unto him the name which is above every name; that in the name of Jesus every knee should bow, of things in heaven and things on earth and things under the earth, and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father."
"Hear, O Israel: Jehovah our God is one Jehovah:"
"Behold, the days come, saith Jehovah, that I will make a new covenant with the house of Israel, and with the house of Judah: not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was a husband unto them, saith Jehovah. But this is the covenant that I will make with the house of Israel after those days, saith Jehovah: I will put my law in their inward parts, and in their heart will I write it; and I will be their God, and they shall be my people. And they shall teach no more every man his neighbor, and every man his brother, saying, Know Jehovah; for they shall all know me, from the least of them unto the greatest of them, saith Jehovah: for I will forgive their iniquity, and their sin will I remember no more."
Frequently asked
Do Christians believe in the Old Testament?
Yes, Christians affirm the Old Testament (which they often call the Hebrew Bible) as sacred, inspired Scripture—the foundational revelation of God's character, His covenant with Israel, and prophecies concerning the Messiah. The New Testament writers frequently quote and allude to the Old Testament, viewing it as pointing forward to Jesus Christ. It provides the historical, theological, and moral framework necessary to understand God's redemptive plan unveiled in the New Covenant. Christians consider both testaments to be the unified Word of God.
What is the Jewish view of Jesus?
In Judaism, Jesus is generally viewed as a historical figure, but not as the Messiah, the Son of God, or a divine being. Jewish scholars and texts typically consider him to be a Jewish preacher or rabbi who founded a new religion, but one that departed from traditional Jewish understandings of God and Law. The messianic prophecies are understood differently, and Jesus' claims (or claims made about him) of divinity are seen as incompatible with Jewish monotheism.
How do dietary laws differ?
In traditional Judaism, the kosher dietary laws (kashrut) derived from the Torah (e.g., Leviticus 11, Deuteronomy 14) are meticulously observed. These laws dictate which foods may be eaten, how they must be prepared, and which foods may not be combined. For Christians, the New Testament teaches that all foods are clean (Mark 7:19; Acts 10:15; Romans 14:14). While some Christians may choose specific diets for personal or health reasons, the ceremonial dietary laws of the Old Testament are not considered binding for salvation or sanctification, as they are seen as fulfilled in Christ.
Are there historical connections between Christianity and Judaism?
Absolutely. Christianity emerged directly from first-century Judaism. Jesus and his early followers were all Jewish, adhering to Jewish customs and worshipping in the Temple and synagogues. The New Testament documents are largely written by Jewish authors. Early Christians saw themselves as the continuation and fulfillment of God's promises to Israel. Over time, as the movement grew and included more Gentiles, and as theological differences solidified, Christianity developed into a distinct religion, though its roots remain firmly in its Jewish heritage.
