One God, Many Names: Uncovering the Shared Roots of Faith

---

What if the differences between Christianity, Judaism and Islam were more about language, culture, and tradition than the divine being itself? It’s a bold question, but one that scholars are increasingly exploring, revealing a fascinating truth: Christians, Jews and Muslims may all be worshiping the same God—just under different names.

A Linguistic Journey Back in Time

Let’s begin with the names we use for God. In Aramaic, the language Jesus spoke, God is called Alaha. In Arabic, it's Allah. In Hebrew, you'll hear Elohim or Yahweh. On the surface, these names sound distinct, even foreign to each other. But take a deeper look, and you’ll find that they are all branches of the same ancient Semitic tree.

Dr. Lina Kareem, a linguist specializing in Semitic languages, explains: “The differences are mostly linguistic and cultural. At their core, these faiths are talking about the same divine being.” She’s not alone in this view. The shared roots of these terms trace back to a Proto-Semitic word for “god,” connecting them to the monotheistic God of Abraham—the patriarch revered by all three faiths.

• Aramaic Alaha: Spoken by Jesus and early Christians, it’s a close cousin to Hebrew’s Elohim.

• Arabic Allah: Used by Muslims and even Arabic-speaking Christians and Jews, Allah is thought to stem from al-ilāh (“the god”), echoing its Semitic relatives.

• Hebrew Elohim and Yahweh: Elohim is a general term for God, while Yahweh (the sacred Tetragrammaton, YHWH) is the personal name of the God of Israel.

These are not mere coincidences. They're linguistic breadcrumbs that point back to a shared heritage, where different cultures express their understanding of the same divine essence.

One God, Different Lenses

If the names for God in Christianity, Judaism and Islam trace back to the same divine source, does that mean these faiths are identical? Not quite. While the core concept of God is remarkably similar, each tradition understands this divine being through its own theological lens.

Jews emphasize strict monotheism and the covenant between God and Israel, focusing on laws and the intimate relationship with the divine as outlined in the Hebrew Bible. Christians, however, introduce a more complex understanding with the Trinity—Father, Son, and Holy Spirit—which is central to their faith. Muslims, like Jews, hold to the absolute oneness of God, rejecting any division or incarnation. For Muslims, God (Allah) is singular, transcendent, and beyond human comprehension.

Yet, despite these theological nuances, the foundation remains strikingly similar. All three faiths trace their lineage to Abraham, the father of monotheism, whose story unites the Hebrew Bible, the New Testament, and the Quran. As one interfaith leader put it during a dialogue reported by the National Catholic Reporter: “We worship the same God—just with different understandings.”

Why It Matters Now

This shared heritage isn’t just a fascinating tidbit for history buffs. It’s sparking a quiet revolution in interfaith dialogue and understanding. In a world that often seems divided along religious lines, recognizing this common ground offers a powerful bridge for connection. From university panels to local community gatherings, people are starting to ask: If we’re all reaching for the same divine, can’t we talk about it?

Take the 2011 Rome dialogue hosted by the Cambridge Interfaith Programme, where Christian, Jewish, and Muslim leaders came together to explore their shared scriptures. Or the World Jewish Congress’s ongoing efforts to build understanding and cooperation between faiths. These aren’t just lofty ideals—they’re real conversations grounded in the belief that our differences don’t erase our shared roots.

Of course, not everyone agrees. Some Christians argue that the concept of the Trinity sets their God apart, while others contend that theological differences—such as the Christian belief in the divinity of Jesus—mean that the three faiths are not worshiping the same God. This debate has been simmering for centuries, and it’s unlikely to be resolved anytime soon. But even amidst the disagreements, the linguistic and historical ties remain compelling.

A Call to Curiosity and Compassion

So where does this leave us? Perhaps with more questions than answers—and that’s okay. Whether you’re a believer, a skeptic, or simply curious about the world’s major religions, this shared legacy invites us to dig deeper into our understanding of God and our neighbors. Next time you hear Allah, Yahweh, or Alaha, think about the ancient threads that bind them together. It’s a reminder that beneath the surface of our differences, there’s often much more in common than we realize.

It’s easy to get caught up in the differences—especially when it comes to religion, where centuries of tradition, ritual, and belief can feel like insurmountable walls. But these walls are not always as high as they seem. The conversation about shared roots invites us to ask bigger questions about identity, faith, and what it means to seek a higher truth.

So, what do you think? Does the idea of one God with many names change how we see faith? Can this shared heritage help build bridges instead of barriers? Let’s keep the conversation going—because the more we talk, the more we may discover about ourselves and each other.
