The topic of whether or not Christians and Muslims worship the same God has absolutely ignited the media in recent months. For whatever reason, this question – do Muslims and Christians worship the same God – has been all over my Facebook feed, and just in the past few weeks has been posted by Ravi Zecharias, Franklin Graham, Billy Graham, the Christian Apologetics and Research Ministry, and Answering Islam, among others…and not always with the same answer.
Without question, there are many similarities. Both Muslims and Christians (and Jews) trace their lineage back through Abraham (Muslims through Ishmael, Christians and Jews through Isaac), and all three maintain a largely Old Testament-based view of monotheism. If a Muslim and a Christian were to list the attributes of God, the lists would look remarkably similar – a “spaceless, timeless, immaterial, powerful, personal creator God” would accurately describe both.
However, similar descriptions cannot mask clear and critical differences. While my perspective may not agree with all these other bloggers, at the very least I hope to clarify the Christian concept (the Godhead or Trinity) as well as the Muslim concept (called tawhid), both of which are frequently misunderstood by Christians.
The Christian Concept: The Godhead
Most Christians likely (hopefully) have a basic understanding of the Biblical concept of God. He is manifest in three persons – the Father, the Son, and the Holy Spirit – all sharing one essence (Godhood). The three are equal in status and power, but distinct in personhood. This has frequently been mischaracterized as polytheism or as an outright contradiction, though this usually does little more than expose a misunderstanding of the theology behind the belief.
Some have tried to construct analogies to understand the Trinity (an egg, water, even my role as a father/husband/son/brother/etc), but all of these analogies fall short or commit a logical or theological fallacy. When it comes to really trying to understand the idea of “three in one,” I side with Martin Luther, who said, “Show me a worm that can comprehend a man, and I’ll show you a man who can comprehend the triune God.” Though this may border on the incomprehensible, it is without a doubt Biblical. The word “trinity” doesn’t appear in Christian doctrine until the middle of the third century, it is clearly taught through five basic points in the Bible:
- There is one God (Isaiah 43:10, 44:6, 8, 45:5, 14, 18, 21, 22, 46:9, 47:8, John 17:3, 1 Cor. 8:5-6, Gal. 4:8-9).
- God the Father is God (Deut 6:4 and throughout the Old Testament, as well as John 6:27; 20:17; 1 Cor 8:6; Gal 1:1; Eph 4:6; Phil 2:11; 1 Pet 1:2).
- Jesus Christ is God (John 8:12-59; Mark 2:3-7, Col 2:9; John 1:1-4; Acts 5:31; Col 3:13; Ps 130:4; Jer 31:34).
- The Holy Spirit is God (Acts 5:3-4, 9; 1 Cor 2:10-11; Romans 8:9-11).
- These three are equal, co-eternal, and distinct (Eph 3:15; John 5:18; 1 Cor 2:10).
Understood this way, it is clear that while the actual word “trinity” doesn’t have to appear in Scripture, the concept is clearly taught. There are book-length treatments of this topic (especially good is James R. White’s The Forgotten Trinity), but this will have to suffice for now, and it is sufficient to point out the differences.
The Muslim Concept: Tawhid
In Islam, the doctrine of Allah is called tawhid. It is the central and defining doctrine of all Islam, and declares absolute monotheism, the unity and uniqueness of God as creator and sustainer of the universe. More than just a religious belief, this doctrine has been central to Islamic reformers and activists as an organizing principle for human society and the basis of religious knowledge, history, metaphysics, aesthetics, and ethics, as well as social, economic, and world order. Muslims are fiercely monotheistic, insofar as anything that even approaches equating something to Allah is one of the most severe sins in Islam (known as shirk). This strict monotheism is the root of all other beliefs, and the root of all values in the Muslim worldview. All values in Muslim religion derive from devoting one’s heart to Allah, and it is through this singly and wholeheartedly devoted love that a Muslim comes to divorce him/herself from the ways and things of this world.
Despite the differences within Islam and the sectarianism discussed in the first article of this series, on this topic Muslims are almost completely united. Tawhid has been a rallying cry of Islam for centuries, uniting the Muslims throughout their history under the banner of various leaders from Ibn Taymiyya (14th Century) to Abd Al-Wahhab (18th Century) to the present day. No matter how diverse Muslims history has been, they have always re-united around the central doctrine of the oneness of Allah, the tawhid.
On the surface, this sounds remarkably similar to the Christian theology of God, but when we turn to the center of Christian faith – Christ Himself – the differences emerge irreconcilable. Muslims deny that God had a son, and deny that Christ is divine, and would never consider Allah a “father” in the sense that Christians speak of their God. They deny both the deity of Christ and His resurrection, going so far as to consider these beliefs blasphemy (Qur’an 5:17, 5:73, 5:75). If Christians were to speak only of the Father of the Old Testament, the divine Yahweh of Abraham, Isaac, and Jacob, and describe His actions and His attributes, Muslims would likely agree with nearly every word.
When we advance to the New Testament and the deity of Christ and the resurrection, arguably the two most central doctrines of the Christian faith, we must part ways with the tawhid of Islam and embrace the Trinity of the Bible. Do Muslims and Christians worship the same God? If we are willing to deny the deity of Christ and the resurrection, then yes — but we cannot. To claim Christianity is to affirm doctrines expressly denied by Islam, and therefore we cannot worship the same God. So how do we engage Muslims in conversation, and what common ground can we find for friendship and evangelism? That’s what we’ll discuss in the next blog.
