ALLAH IN ISLAM IS NOT THE SAME AS THE GOD OF CHRISTIANITY? KEY DIFFERENCES ACCORDING TO THE BIBLE AND THE QUR’AN
EDIS TV — Biblical Studies, Theology, and Comparative Religion
Introduction: Is the God of Islam the Same as the God of Christianity?
Is Allah, as understood in Islam, the same as the God worshiped by Christians? This question frequently arises in interfaith discussions, particularly when comparing the teachings of the Bible and the Qur’an.
For Christians, knowing God means more than simply knowing a divine name or acknowledging the existence of a supreme being. It involves understanding who God is, how He has revealed Himself, who Jesus Christ is, and how humanity can receive salvation according to the Bible.
Islam, meanwhile, has its own understanding of Allah, divine oneness, the identity of Jesus, and the nature of revelation.
From a Christian theological perspective, the Islamic concept of God differs fundamentally from the Christian understanding of God, particularly regarding the Trinity, the divinity of Jesus Christ, and salvation.
However, an important distinction must be made between the word used for God and the theological understanding of who God is. These are not necessarily the same question.
1. The First Biblical Evidence: The Word Was God
One of the most important foundations of Christian faith is found in the Gospel of John.
John 1:1 (KJV):
“In the beginning was the Word, and the Word was with God, and the Word was God.”
This verse is central to the Christian understanding of Jesus Christ. In John's Gospel, the Word is not merely a message delivered by God. The Word is described as being with God and as being God.
John 1:14 continues by declaring that the Word became flesh and dwelt among humanity.
According to mainstream Christian interpretation, these verses refer to Jesus Christ, who is understood as the eternal Word of God incarnate.
Here lies a fundamental difference between Christianity and Islam. Islam honors Jesus, known as Isa al-Masih, as the Messiah and a messenger of God, but it does not accept the Christian doctrine that Jesus is God incarnate.
The disagreement, therefore, is not merely about the name of God. It concerns the identity of Jesus and His relationship with God.
From a Christian perspective, the testimony of John's Gospel provides a significant foundation for affirming the divinity of Christ.
2. The Second Biblical Evidence: Thomas Calls Jesus “My Lord and My God”
Consider the words spoken by Thomas after encountering the risen Jesus.
John 20:28 (KJV):
“And Thomas answered and said unto him, My Lord and my God.”
For Christians, this is one of the most important biblical passages supporting the divinity of Jesus Christ.
Thomas does not merely describe Jesus as a prophet or a messenger who receives divine revelation. He addresses Jesus as “my Lord and my God.”
Within Christian theology, this confession must be understood alongside the broader testimony of John's Gospel concerning the relationship between the Father and the Son.
Islam, however, does not accept the conclusion that Jesus is God on the basis of this passage. Islamic theology regards Jesus as a prophet and messenger of Allah, not as God in human form.
This raises an important theological question: if Christians accept the testimony of John's Gospel concerning the identity of Jesus, can they accept a rejection of His divinity without changing their interpretation of that testimony?
From the Christian perspective, denying the divinity of Christ represents a fundamental theological disagreement.
3. The Third Biblical Evidence: Jesus Declares His Unity with the Father
In John 10:30, Jesus declares:
“I and my Father are one.”
Christians frequently refer to this passage when explaining the unique relationship between Jesus and the Father.
The doctrine of the Trinity does not teach that the Father and the Son are the same person. Mainstream Christianity teaches that the Father, the Son, and the Holy Spirit are distinct persons who share one divine being.
Christianity therefore does not teach the existence of three separate gods. It teaches one God in three persons.
Islam has a different understanding of divine oneness. Surah Al-Ikhlas, chapter 112, emphasizes Allah's absolute oneness and declares that He neither begets nor is begotten.
These differences demonstrate that Christianity and Islam offer distinct theological explanations of God's nature and the identity of Jesus.
From the Christian perspective, God's oneness does not exclude the Father, the Son, and the Holy Spirit as understood in the doctrine of the Trinity.
4. The Fourth Biblical Evidence: Jesus Is the Way to the Father
In John 14:6, Jesus declares:
“I am the way, the truth, and the life: no man cometh unto the Father, but by me.”
This statement occupies a central place in Christian faith.
According to Christianity, Jesus is not merely a moral teacher or a prophet. He is at the center of God's plan of salvation for humanity.
For this reason, Christian faith places the person, death, and resurrection of Jesus Christ at the heart of salvation.
Islam honors Jesus as the Messiah and a messenger of Allah, but it does not assign Him the same theological status that He holds in Christianity.
Consequently, the two religions differ in their understanding of how humanity should approach God and receive salvation.
For Christians who accept the authority of the Bible, John 14:6 provides a foundational reason to affirm that the relationship between humanity and God must be understood through Jesus Christ.
5. The Fifth Biblical Evidence: The Death and Resurrection of Jesus Are Central to Christianity
The Apostle Paul emphasizes the importance of Christ's resurrection in 1 Corinthians 15:14:
“And if Christ be not risen, then is our preaching vain, and your faith is also vain.”
This verse demonstrates that Christian faith cannot be separated from the belief in Jesus' death and resurrection.
In Christian theology, Jesus' death is understood as part of God's work of redemption, while His resurrection represents victory over death.
Islam has a different understanding of the crucifixion. Surah An-Nisa 4:157–158 states that they did not kill or crucify Jesus as they claimed and declares that Allah raised him to Himself.
This is not a minor disagreement. It concerns the very center of the Christian proclamation about the cross and the resurrection.
From a Christian perspective, if the death and resurrection of Jesus are central to salvation, then differences concerning these events have profound theological consequences.
6. The Sixth Biblical Evidence: The Bible and the Qur’an Present Different Accounts of Jesus
Consider the following comparison:
| Subject | The Bible According to Christian Faith | Islamic Understanding |
|---|---|---|
| Identity of Jesus | The Word made flesh; confessed as Lord and God (John 1:1, 14; 20:28) | Isa al-Masih, a prophet and messenger of Allah |
| The Trinity | One God in three persons: Father, Son, and Holy Spirit | Rejects the Christian doctrine of the Trinity |
| Crucifixion | Jesus was crucified and died; His resurrection is central to Christian faith | Qur’an 4:157–158 rejects the claim that Jesus was killed or crucified as asserted |
| Salvation | Centered on the redemptive work, death, and resurrection of Christ | A different theological framework involving faith, deeds, and God's mercy |
| Relationship with God | Jesus is the way to the Father | Worship of the one God without accepting Jesus as God incarnate |
This comparison reveals substantial differences between the teachings of the two religions.
However, these differences do not mean that Christianity and Islam have absolutely nothing in common. Both traditions affirm the existence of a Creator, emphasize devotion to God in their respective frameworks, and recognize figures who also appear in biblical traditions.
Shared elements do not eliminate the fundamental disagreements concerning the identity of Jesus, the Trinity, and salvation.
7. Is the Name Allah Different from the Christian Name for God?
This question requires careful consideration.
Some people argue that because Muslims use the word Allah, while many Christians use God or Lord, the two groups must necessarily be referring to completely different beings.
That conclusion cannot be established from the name alone.
Linguistically, Allah is the Arabic word for God. Arabic-speaking Christians also use the word Allah, including in Arabic translations of the Bible. The word is not exclusive to Muslims.
Therefore, the claim that the word Allah belongs exclusively to Islam, or that Christians cannot use it, is inconsistent with actual Arabic-language usage.
Where, then, does the fundamental disagreement lie?
The central issue is the theological understanding of God's identity, not simply the word used to refer to Him.
In Christianity, God is understood as Father, Son, and Holy Spirit. Jesus Christ is believed to be the Word who became flesh.
In Islam, Allah is understood as absolutely one, without accepting the doctrine of the Trinity or the divinity of Jesus.
Consequently, from a Christian theological perspective, one may argue that the Islamic understanding of God does not correspond to the revelation of God as understood through Jesus Christ in the Bible.
However, the claim that Muslims necessarily worship a completely unrelated being simply because they use the word Allah must be distinguished from the argument that the two religions teach different doctrines about God. These are separate questions.
8. Why Do Christians Reject a Concept of God That Excludes Christ?
For Christians, Jesus is not an optional figure in religious history. He is central to the knowledge of God.
In John 14:9, Jesus tells His disciples that whoever has seen Him has seen the Father. In Christian interpretation, this statement describes the unique relationship between Jesus and the Father; it does not mean that the Father and the Son are the same person.
Colossians 1:15–20 also describes Christ as the image of the invisible God and explains His role in creation and reconciliation.
Based on these passages, Christians believe that knowing God cannot be separated from knowing Christ.
Because Islam does not accept the divinity of Jesus as taught in mainstream Christian theology, a Christian apologist may conclude that the Islamic understanding of God is incompatible with the New Testament's presentation of God through Jesus Christ.
This is a theological argument grounded in the question of who Jesus is according to the Bible and whether His testimony is accepted.
9. Does the Trinity Mean That Christians Worship Three Gods?
A frequent objection to Christianity is the claim that the doctrine of the Trinity teaches the worship of three gods.
Mainstream Christian theology rejects this characterization.
The Trinity refers to one divine being in three persons: the Father, the Son, and the Holy Spirit. They are not understood as three independent gods.
Matthew 28:19 mentions the Father, the Son, and the Holy Spirit in the baptismal formula. Meanwhile, 2 Corinthians 13:14 brings together Jesus Christ, God, and the Holy Spirit in Paul's closing blessing.
These passages form part of the biblical foundation used in discussions of the Trinity.
It is true that the technical term Trinity does not appear as a single word in the Bible. The doctrine developed as a theological formulation intended to explain the combined biblical testimony concerning God, Jesus, and the Holy Spirit.
Therefore, a Christian defense of the Trinity should engage with the Bible as a whole rather than assuming that the disagreement can be settled simply by one side declaring the doctrine irrational.
10. Conclusion: Theological Differences Matter More Than the Name Alone
The comparison above provides substantial grounds for Christians to affirm that the Islamic understanding of God differs fundamentally from the Christian understanding of God.
The principal differences concern:
The divinity of Jesus: The Bible, according to mainstream Christian interpretation, teaches Christ's divine identity, whereas Islam does not accept Jesus as God.
The Trinity: Christianity understands God as one divine being in three persons, while Islam rejects this doctrine.
The crucifixion and resurrection: The two religions differ in their understanding of events central to Christian faith.
Salvation: Christianity places Christ's redemptive work at the center of salvation, whereas Islam has a different theological framework.
Therefore, if the title “Allah in Islam Is Not the Same as the God of Christianity” is intended to emphasize that Islamic theology differs from Christian doctrine, the argument can be supported by examining these genuine theological differences.
However, if the title is intended to claim that the word Allah can refer only to the Islamic concept of God, that claim is not supported by the use of Arabic in Christian traditions.
For Christians, the most important question is not merely which name is used for God, but whether God's identity and His work of salvation are understood according to the biblical revelation of Jesus Christ.
EDIS TV's message: Religious differences should be discussed by examining primary sources, reading passages in context, and evaluating arguments critically. A strong faith does not require misrepresenting facts or insulting people of other religions.
