Do Jews and Christians Worship the Same God?

This question sits at the intersection of theology, history, and interfaith relations — and it is more complex than a simple yes or no. Christians and Jews share the Hebrew Scriptures, trace their roots to Abraham, and both insist on the absolute unity and holiness of God. Yet Christianity makes claims about God that Judaism considers not merely different but incompatible. The question deserves a careful answer that neither flattens the real differences nor overstates them.

What Christians and Jews Share

The common ground is substantial. Both traditions affirm:

• One God — the Creator of heaven and earth, who is holy, just, and merciful
• The same Hebrew Scriptures (what Christians call the Old Testament)
• The God of Abraham, Isaac, and Jacob as the one true God
• God's covenant faithfulness, his revelation through the prophets, and his moral law
• The expectation of a coming Messiah (though they differ on whether he has come)

This shared foundation is not trivial. The God Christians worship did not begin with the New Testament. He is explicitly the God of Israel — the one who called Abraham, delivered Israel from Egypt, gave the law at Sinai, and spoke through Isaiah, Jeremiah, and the Psalms. Jesus himself was Jewish, worshipped in the synagogue, quoted the Torah, and said he came "not to abolish the Law or the Prophets but to fulfil them" (Matthew 5:17).

Where the Paths Diverge

The divergence is equally real and should not be minimised. Christianity makes three claims about God that Judaism rejects:

1. The Trinity. Christianity teaches that God is one being in three persons — Father, Son, and Holy Spirit. Judaism holds that God is absolutely and indivisibly one (the Shema: "Hear O Israel, the LORD our God, the LORD is one" — Deuteronomy 6:4). Many Jewish theologians argue that the Christian doctrine of the Trinity is a form of polytheism or at minimum a fundamental distortion of monotheism. Christians disagree, arguing that the Trinity is a deeper account of the same God's inner life — but the disagreement is real and significant.

2. The Incarnation. Christianity teaches that the second person of the Trinity became human in Jesus of Nazareth — that God himself took on flesh. This is not merely a claim about Jesus; it is a claim about God. It means God entered history in a way Judaism does not recognise. To say "Jesus is God" is to say something about God's nature that Judaism explicitly and emphatically denies.

3. The Messiah. Judaism awaits a Messiah who will restore the Davidic kingdom, gather the exiles, rebuild the Temple, and bring universal peace. Jesus did not do these things in his first coming — which is why Judaism rejects the Christian identification of Jesus as Messiah. Christianity responds that Jesus fulfilled the messianic prophecies in unexpected ways and will complete the restoration at his return. The disagreement here is not peripheral — it concerns the central expectation of both faiths.

Same God, Different Understanding — or Different God?

Theologians have answered this question in different ways.

The "same God, different understanding" view holds that both Jews and Christians are worshipping the one God of Abraham, but with different degrees of revelation. Christians believe the fuller revelation came in Jesus Christ — but the God being worshipped is the same God, just understood differently. On this view, Jewish worship of God is genuine, though incomplete from a Christian perspective.

The "different enough to matter" view holds that because God's identity is bound up with his self-revelation, and because Christians believe God has definitively revealed himself as Trinity and as incarnate in Jesus, a conception of God that excludes these realities is a conception of a different God — not because Jews are worshipping an idol, but because the God who actually exists has a nature that Jewish theology denies.

The theologian Miroslav Volf, in his book Allah: A Christian Response, argues that the God of the Bible and the God of Islam are "sufficiently similar" to be considered the same God worshipped differently. A similar argument applies to Judaism with even more force — given the far greater common ground.

The Catechism of the Catholic Church states that Jews and Christians worship the same God: "The Jewish faith, unlike other non-Christian religions, is already a response to God's revelation in the Old Covenant." Most Protestant traditions would agree in substance, while insisting that saving knowledge of God comes through Christ alone.

The Crucial Distinction: Same God, Different Salvation

Perhaps the most honest answer is this: Jews and Christians direct their worship toward the same God — the God of Abraham, Isaac, and Jacob — but they understand that God differently, and Christianity teaches that the fullest and final revelation of who that God is came in Jesus Christ.

This means Christianity does not view Judaism as worshipping a false god or an idol. The God of Israel is the God of the Church. But it does mean that Christianity believes Judaism has not yet received the full picture of who that God is — specifically, that he is Father, Son, and Holy Spirit, and that he has acted definitively in Jesus to accomplish what the Law and Prophets pointed toward.

For Christians, the right response to this is not superiority but gratitude — and a recognition that the faith we have received was born in Israel, was given through Jewish apostles, and is rooted in the Jewish Scriptures. Paul writes in Romans 11 that Gentile believers have been "grafted in" to the olive tree of Israel. Christianity is not a replacement for Israel's faith. It is, in its own self-understanding, its fulfilment.
