Do Christians and Muslims Worship the Same God? A Three-Faith Comparison

Judaism's position is nuanced. The tradition firmly affirms one, indivisible God — the God of Abraham, Isaac, and Jacob — and on that basis recognizes that both Christianity and Islam are, in some sense, engaging with the same ultimate reality. Medieval philosopher Maimonides (1135–1204) acknowledged that Islam is straightforwardly monotheistic and that Muslims worship the God of Israel without compromise. His view of Christianity was more complicated: he considered Trinitarian belief a form of shituf (association), which, while not full idolatry for non-Jews, does introduce partners into the divine unity in a way Judaism cannot accept.

The Shema — Hear O Israel, the LORD our God, the LORD is one — sets the baseline. Any theology that multiplies the divine persons, even within a unity, is seen as departing from that baseline. So Judaism's answer is roughly: Muslims, yes, probably the same God; Christians, the same God in origin but significantly re-described. Modern Orthodox thinker Rabbi Joseph B. Soloveitchik (d. 1993) was cautious about interfaith theological dialogue precisely because he felt the categories were incommensurable. The disagreement isn't trivial.

Christians are divided on this question, and the debate intensified publicly in 2015 when Wheaton College professor Larycia Hawkins wore a hijab and stated Christians and Muslims 'worship the same God.' The college placed her on administrative leave, illustrating how live the controversy is within evangelical Protestantism.

Those who say yes — including theologians like Miroslav Volf in his 2011 book Allah: A Christian Response — argue that both traditions direct worship toward the one Creator God of Abraham, and that doctrinal disagreements about the Trinity or the nature of Jesus don't necessarily mean the referent of worship is different. The God Christians pray to is not a different being; Christians and Muslims are simply wrong about each other's God in different ways.

Those who say no — including apologists like Nabeel Qureshi and theologians like R.C. Sproul — contend that the Trinity is not a peripheral add-on but the very identity of the Christian God. To strip away the Father-Son-Spirit relationship is to describe a fundamentally different deity. On this view, sincerity of worship doesn't determine its object.

Mainstream Catholic teaching, reflected in Nostra Aetate (1965), acknowledges that Muslims 'adore the one, merciful God' — a significant concession toward sameness, though it stops short of full theological equivalence.

Islam's answer is clear at one level and complicated at another. The Quran consistently presents Allah as the same God worshipped by Abraham, Moses, and Jesus — not a new deity but the original one, whose message was progressively distorted and then restored through Muhammad. The Quranic Jesus himself declares: 'Allāh is my Lord and your Lord, so worship Him' Quran 19:36, directly identifying the God of Jesus with the God of Islam.

So in terms of referent, Islam insists it worships the same God as Jews and Christians. The Quran in 10:104 has the Prophet declare that he worships 'Allāh, who causes your death' — the one sovereign Creator Quran 10:104 — distinguishing true worship from the false objects others associate with God Quran 16:73.

The complication is that Islam rejects the Trinity categorically. Surah 4:171 warns against saying 'Three.' From an Islamic standpoint, Christians have introduced a serious theological error (shirk, association of partners with God) that distorts their understanding of who God is. So while Islam affirms the same God in principle, it holds that mainstream Christianity's Trinitarian framework misrepresents that God fundamentally. The sameness is real but the Christian description is, from Islam's view, corrupted.

Scholar Reza Aslan and others in comparative religion tend to emphasize the shared Abrahamic root; traditionalist Muslim scholars like Ibn Taymiyya (d. 1328) were more emphatic that Trinitarian theology constitutes a departure from true monotheism that cannot simply be glossed over.

No Jewish scriptures were provided, so this answer cannot make a cited claim about how Judaism positions the question beyond noting that the Qur’an passages given do not directly address Jewish doctrine Quran 10:104Quran 16:73Quran 19:36.

From the Qur’an’s portrayal of Jesus, he is quoted as saying: “Allah is my Lord and your Lord, so worship Him,” which presents Jesus as directing worship to the one God Quran 19:36. No New Testament or other Christian texts were provided, so no further Christian-doctrine claims can be made here beyond this Qur’anic depiction Quran 19:36.

Islam explicitly commands exclusive worship of Allah and rejects worship of anything besides Him Quran 10:104Quran 16:73. The Qur’an instructs Muhammad to worship Allah alone and distinguishes that from others’ devotions Quran 10:104, and it criticizes reliance upon beings or things that have no power to provide sustenance Quran 16:73. It also quotes Jesus affirming worship of Allah, portraying continuity in directing worship to the one God Quran 19:36. Contemporary Muslim scholars often appeal to these verses when discussing whether Christians and Muslims refer to the same ultimate deity, though they note deep disagreements about how God is understood; this debate can’t be settled further here with only these passages Quran 10:104Quran 16:73Quran 19:36.
