Christianity & Judaism

“For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek.” — Romans 1:16

Christianity and Judaism share a relationship unlike any other pairing of world religions. Christianity was born within Judaism. Jesus was a Jew. The apostles were Jews. The entire Old Testament — the Torah, Prophets, and Writings — is sacred Scripture for both communities. Yet the two traditions diverge on the most consequential question in history: Is Jesus of Nazareth the promised Messiah and divine Son of God?

Shared Heritage

The common ground between Christianity and Judaism is vast and profound:

• Monotheism: Both confess that there is one God, the Creator of heaven and earth — the God of Abraham, Isaac, and Jacob (Deuteronomy 6:4; Mark 12:29)
• Covenant: Both traditions are shaped by God’s berit (בְּרִית) — “covenant, binding agreement” — with His people, from Abraham through Moses and beyond (Genesis 15; Exodus 19–24)
• The Hebrew Scriptures: Christians receive the Tanakh (תַּנַ”ךְ) — an acronym for Torah (Law), Nevi’im (Prophets), and Ketuvim (Writings) — as the inspired Word of God, the same texts that shaped Second Temple Judaism
• Messianic hope: Both traditions look for the fulfillment of God’s promises, though they disagree sharply on whether that fulfillment has come
• Ethical monotheism: The conviction that the one God is holy and demands righteousness from his people (Micah 6:8; Leviticus 19:2)

The Great Divergence

The central question is the identity of Jesus. Christians confess him as mashiach (מָשִׁיחַ) — “anointed one, Messiah” — and as the divine Son of God. Judaism rejects both claims.

Jewish Objections to Christianity

Jewish theology raises serious objections that Christians must take seriously:

• The Messiah should bring world peace: Isaiah 2:4 envisions swords beaten into plowshares. If Jesus is the Messiah, why is there still war and suffering?
• The Trinity violates monotheism: The Shema declares “Hear, O Israel: The LORD our God, the LORD is one” (Deuteronomy 6:4). How can God be three persons?
• Jesus did not fulfill the Messianic prophecies: He did not rebuild the Temple, regather all Israel, or establish universal knowledge of God (Ezekiel 37:26-28; Isaiah 11:9)

Christian Responses

Christians respond to these objections from within the Scriptures both communities share:

• Two comings: The prophets describe both a suffering servant (Isaiah 53) and a reigning king (Daniel 7:13–14). Christians affirm that Jesus fulfilled the suffering-servant prophecies at His first coming and will fulfill the kingly prophecies at His return. The Jewish concept of Mashiach ben Yosef (a suffering Messiah) alongside Mashiach ben David (a reigning Messiah) in later rabbinic tradition suggests that even within Judaism the tension between suffering and glory was recognized
• Complex oneness: The Hebrew word echad (אֶחָד) in the Shema means “one.” Christians should not overstate the linguistic argument — echad does not inherently mean “compound unity.” However, the broader Old Testament witness reveals a God who is one yet who speaks of Himself in plural terms (Genesis 1:26), who appears as the Angel of the LORD who is identified with YHWH yet distinct from Him (Genesis 16:13; Exodus 3:2–6), and whose Word and Spirit act as distinct personal agents (Psalm 33:6; Isaiah 48:16). The Trinity is not derived from a single word but from the full pattern of divine self-revelation
• Fulfillment, not replacement: Christianity claims to fulfill the hopes of Israel, not abolish them. Jesus Himself said, “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them” (Matthew 5:17). The new covenant promised in Jeremiah 31:31–34 is understood by Christians not as the annulment of God’s relationship with Israel but as its deepening and universalizing

God’s Ongoing Faithfulness to Israel

The apostle Paul wrestled deeply with the relationship between the church and Israel in Romans 9-11. His conclusions are vital:

• God has not rejected his people Israel (Romans 11:1-2)
• A partial hardening has come upon Israel “until the fullness of the Gentiles has come in” (Romans 11:25)
• “All Israel will be saved” — God’s covenant purposes for the Jewish people remain (Romans 11:26)
• The gifts and calling of God are irrevocable (Romans 11:29)

Christians must approach Judaism not with triumphalism or contempt, but with gratitude for the heritage received and hope for the fulfillment of God’s promises to Abraham’s descendants. For a fuller treatment, see Israel and the Church.

The tragic history of Christian antisemitism — from the patristic adversus Judaeos literature through medieval persecutions to the horrors of the twentieth century — stands as a grievous failure to heed Paul’s warning: “Do not be arrogant toward the branches… it is not you who support the root, but the root that supports you” (Romans 11:18). The Second Vatican Council’s declaration Nostra Aetate (1965) marked a turning point, repudiating the charge of collective Jewish guilt for Christ’s death and affirming that “the Jews should not be presented as rejected or accursed by God.” Evangelical and Orthodox leaders have issued similar statements. Genuine Christian faithfulness requires both theological honesty about the claims of Christ and deep repentance for the sins committed in His name against the Jewish people.

The Heart of the Matter

The disagreement between Christianity and Judaism is not peripheral. It concerns the identity of God, the meaning of yeshuah (יְשׁוּעָה) — “salvation, deliverance” — and the fulfillment of history. Christians believe that in Jesus — whose Hebrew name Yeshua (יֵשׁוּעַ) itself means “YHWH saves” — the God of Israel has acted decisively to redeem the world, not in spite of the Jewish Scriptures but in fulfillment of them. As Paul writes, “For all the promises of God find their Yes in him” (2 Corinthians 1:20).

“O the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how inscrutable his ways!” — Romans 11:33
