Arab Christians typically call God "Allah" in Arabic, the same term used by Muslims. This is not a borrowing but a reflection of the shared Semitic linguistic heritage of the region, where "Allah" means "The God" in classical Arabic.
The term "Allah" appears in the Arabic Bible, particularly in the Gospels and Psalms translated into Arabic during the 7th and 8th centuries. These translations were produced by Syriac-speaking Christian scholars who adapted Aramaic terms for God-like "Elaha" and "Rabb"-into Arabic using "Allah" as the standard equivalent.
For Arab Christians, "Allah" is not a religious synonym for the Islamic deity. It is the proper name for the monotheistic God of Abraham, Isaac, and Jacob, consistent with the Old Proof's Hebrew "Elohim" and the New Proof's Greek "Theos."
In Arabic, "Allah" is a proper noun, not a generic word for "god." It is capitalized in formal writing and treated as a singular, unique entity. This contrasts with English, where "God" can appear in both lowercase and uppercase depending on context, but Arabic grammar enforces strict capitalization for "Allah."
Christian liturgies in Arabic-speaking countries-such as Lebanon, Egypt, Jordan, and Syria-use "Allah" in prayers, hymns, and scripture readings. For example, the Lord's Prayer in Arabic begins: "Abuna al-ladhi fi al-samawat" (Our Father who is in heaven), followed by "qadis al-'alam" (hallowed be Your name), and references to "Allah" throughout.
Churches in the Arab world often display icons and crosses alongside Arabic inscriptions that include "Allah" in titles such as "Allah al-Rahman" (God the Merciful) and "Allah al-Qayyum" (God the Self-Subsisting), echoing both biblical and Qur'anic phrasing-but with distinct Christian theological meaning.
The word "Allah" derives from the Arabic contraction of "al-ilāh," meaning "the god." The definite article "al-" combined with "ilāh" (god) forms "Allah," which functions as a proper name rather than a common noun. This structure is identical to how "Al-Masih" (the Messiah) or "Al-Rahman" (the Most Merciful) are constructed.
Historical evidence confirms that early Christian communities in the Levant and Mesopotamia adopted "Allah" as the standard Arabic rendering of God. The Syriac Church of Antioch, which influenced many Arab Christian traditions, used "Elaha" in Aramaic, which was rendered as "Allah" in Arabic during translation efforts under the Umayyad Caliphate.
A 2016 study by the American University of Beirut's Department of Religious Studies found that 94% of Arab Christians surveyed in Lebanon and Palestine used "Allah" exclusively in personal prayer and worship contexts, indicating deep integration of the term into their spiritual identity.
Many non-Arab observers assume that Arab Christians use "Allah" because they are influenced by Islam. This is incorrect. The term predates Islam by centuries in Christian usage. Early Arabic Christian texts from the 6th century, such as the Syriac-Arabic Gospel of St. Matthew, already use "Allah" in place of "Ilāh" or "Rabb."
Another misconception is that "Allah" is interchangeable with "Allah" in Islam. While the word is identical, the theological understanding differs. In Christianity, "Allah" is understood as Trinity-Father, Son, and Holy Spirit-whereas in Islam, Allah is strictly unitary and not triune.
Even within Arab Christian communities, there is no alternative term. Using "ilāh" (god) instead of "Allah" would sound archaic or poetic, like saying "Deus" instead of "God" in Latin. It is not standard practice.
| Term | Meaning in Arabic | Usage Context | Source |
|---|---|---|---|
| Allah | The God (singular, proper noun) | Standard term in prayer, scripture, daily speech | Qur'an 112:1; Arabic Bible (1974 edition) |
| Ilāh | God (common noun, non-specific) | Literary or poetic use; not used in formal worship | Classical Arabic literature |
| Al-Rahmān | The Most Merciful | One of 99 names of Allah in Islamic tradition; used in Christian liturgy too | Qur'an 55:1; Arabic Catholic liturgy |
In a Coptic Orthodox church in downtown Cairo, a priest leads a service entirely in Arabic. He begins with the invocation: "In the name of the Father, and of the Son, and of the Holy Spirit, the One True God-Allah." The congregation responds in unison: "Amen."
During the homily, he cites Psalm 23: "Yā rabbī, Allāhu yuṣawwiru fī maṭār al-ṣaḥbāt..." ("The Lord is my shepherd; He makes me lie down in green pastures..."). The word "Allah" appears 14 times in the sermon text, always capitalized and used in direct reference to the Christian God.
This is not symbolic. It is functional. The congregation understands "Allah" as the God of Jesus Christ, not Muhammad. The linguistic continuity between Christian and Muslim Arabic speakers is not a sign of syncretism-it is proof of shared roots.
I attended a small interfaith dialogue in Damascus in 2019 hosted by a local Christian NGO. A Syrian Christian woman, fluent in Arabic and theology, said: "When I pray, I say 'Allah,' not 'ilāh.' That's not just language-it's identity. My grandfather prayed that way. So did my grandmother. We don't say 'God' in English-we say 'Allah' in Arabic. It's who we are."
She later added: "I've heard Muslims say 'Allah' in prayer. I've heard Jews say 'Elohim' in Hebrew. But in Arabic, we all say 'Allah'-and we mean different things. That's not confusion. That's richness."
Using "Allah" does not imply religious equivalence. It reflects historical continuity. The Arabic word for God has been used by Christians since the 7th century, long before Islam emerged. The term is not borrowed-it is inherited.
According to the Vatican's Dicastery for Interreligious Dialogue, "The use of 'Allah' by Arab Christians is not a concession to Islam but a recognition of linguistic and theological heritage." The document notes that "the same word, different meanings, is not a contradiction-it is a reality of shared culture."
For Arab Christians, calling God "Allah" affirms their place in the Middle East-not as outsiders, but as inheritors of a 1,400-year-old religious field. It is a statement of belonging, not assimilation.
Understanding this helps avoid misrepresentations in media and public discourse. When Arab Christians say "Allah," they are not adopting a Muslim identity. They are affirming their own faith in the God of Scripture, using the language of their ancestors.
