The question of whether Christians, Jews, and Muslims worship the same God has been a subject of considerable debate and reflection among theologians, scholars, and believers alike. To address this question adequately, it is essential to explore the theological foundations, scriptures, and historical contexts of these three monotheistic faiths—Christianity, Judaism, and Islam.
The Concept of God in Judaism
Judaism is the oldest of the three Abrahamic faiths and is rooted in the Hebrew Scriptures, commonly referred to as the Tanakh. The central declaration of Jewish faith is the Shema, found in Deuteronomy 6:4: "Hear, O Israel: The Lord our God, the Lord is one." This verse encapsulates the monotheistic essence of Judaism, emphasizing the oneness and uniqueness of God, known as Yahweh or Jehovah.
In Judaism, God is seen as the Creator of the universe, omnipotent, omniscient, and omnipresent. The relationship between God and the Jewish people is covenantal, initiated with figures like Abraham, Isaac, and Jacob, and later solidified through Moses at Mount Sinai. The attributes of God in Judaism include justice, mercy, and holiness, and He is intimately involved in the affairs of humanity, guiding and correcting His chosen people.
The Concept of God in Christianity
Christianity emerged from the Jewish tradition and shares the same foundational belief in one God, who is the Creator and Sustainer of all things. However, Christianity introduces the doctrine of the Trinity, which posits that God exists as three persons in one essence: God the Father, God the Son (Jesus Christ), and God the Holy Spirit. This is articulated in passages like Matthew 28:19, where Jesus commands His disciples to baptize "in the name of the Father and of the Son and of the Holy Spirit."
The Christian understanding of God is profoundly shaped by the life, death, and resurrection of Jesus Christ. Christians believe that Jesus is the incarnate Word of God (John 1:1, 14), fully divine and fully human, who came to reconcile humanity to God through His sacrificial death and resurrection. This belief is central to the Christian faith and distinguishes it from Judaism and Islam.
The Concept of God in Islam
Islam, the youngest of the three Abrahamic faiths, also proclaims a strict monotheism. The central tenet of Islamic faith is the Shahada, which states, "There is no god but Allah, and Muhammad is his prophet." The name "Allah" is simply the Arabic word for God, used by Arabic-speaking Christians and Jews as well.
In Islam, God (Allah) is understood to be utterly singular, transcendent, and incomparable. The Quran, which Muslims believe to be the final revelation from God, emphasizes His oneness and sovereignty (Surah Al-Ikhlas 112:1-4). Allah is described as merciful and compassionate, yet also just and omnipotent. Like Judaism, Islam rejects any form of division within the Godhead, which includes the Christian doctrine of the Trinity.
Points of Convergence and Divergence
At a high level, all three faiths affirm the existence of one, sovereign God who is the Creator and Sustainer of the universe. This common ground is significant and forms a basis for mutual respect and dialogue.
However, the differences are equally important:
-
The Trinity: Christianity's doctrine of the Trinity is a major point of divergence. Both Judaism and Islam reject this concept, viewing it as incompatible with their understanding of God's oneness.
-
Jesus Christ: In Christianity, Jesus is the Son of God and the second person of the Trinity, whose life and work are central to salvation. Judaism regards Jesus as a historical figure, but not as the Messiah or divine. Islam acknowledges Jesus (Isa) as a prophet and a significant figure, but not as the Son of God or divine.
-
Scriptural Authority: Each faith has its own set of sacred texts. Jews adhere to the Tanakh, Christians to the Bible (including the Old and New Testaments), and Muslims to the Quran. While there are overlapping narratives and figures, the interpretations and theological emphases differ significantly.
Theological Reflections
From a non-denominational Christian perspective, it is essential to recognize both the shared heritage and the distinct revelations that define each faith. The Apostle Paul, in his address to the Athenians at the Areopagus, acknowledged their religiosity and pointed them towards the "unknown god" they worshipped (Acts 17:22-23). He then proclaimed the God of Christian revelation, who "made the world and everything in it" and who "does not live in temples built by human hands" (Acts 17:24).
This approach can be instructive. Christians can affirm the monotheistic faith of Jews and Muslims while also bearing witness to the unique revelation of God in Jesus Christ. The Gospel of John states, "No one has ever seen God, but the one and only Son, who is himself God and is in closest relationship with the Father, has made him known" (John 1:18). This belief in the incarnation and the redemptive work of Christ is foundational to the Christian understanding of God.
Historical and Contemporary Dialogues
Throughout history, there have been various attempts at interfaith dialogue and understanding. The medieval philosopher and theologian Thomas Aquinas engaged with Islamic and Jewish thought, seeking common ground while also articulating the distinctiveness of Christian doctrine. In contemporary times, efforts such as the "A Common Word" initiative have sought to foster mutual understanding and cooperation between Muslims and Christians based on shared values of love for God and neighbor.
Conclusion
In sum, while Christians, Jews, and Muslims all worship one God, the understandings and revelations of that God differ significantly. From a non-denominational Christian perspective, the belief in the Trinity and the incarnation of Jesus Christ are central and non-negotiable aspects of faith that distinguish Christianity from Judaism and Islam. However, the shared commitment to monotheism and the ethical teachings that flow from it provide a basis for respectful dialogue and cooperation.
By recognizing both the commonalities and the differences, Christians can engage meaningfully with Jews and Muslims, bearing witness to their faith while also honoring the sincere devotion of others to the one true God.
