Arabic as a Shared Language of Jewish, Christian, and Muslim Knowledge
Arabic became one of the great shared languages of Abrahamic intellectual life. In the medieval Islamic world, Muslims used Arabic for Qur’anic revelation, law, theology, philosophy, science, and administration; Christians used Arabic for biblical translation, theology, apologetics, liturgy, medicine, and philosophy; and Jews used Arabic and Judeo-Arabic for biblical commentary, law, philosophy, commerce, poetry, and everyday communication. This article examines Arabic as a shared language of Jewish, Christian, and Muslim knowledge without reducing it to a single religious identity. Arabic carried revelation, argument, translation, medicine, metaphysics, grammar, legal reasoning, and interreligious debate. It also clarifies why the word “Allah” should be understood as the Arabic word for God within a shared Semitic and Abrahamic linguistic world, not as the name of a separate deity.
