Why is studying Abrahamic religions alone insufficient for understanding all forms of religious thought in the world?

This is an important question posed by many beginning students in philosophy of religion. The Abrahamic religions—Judaism, Christianity, and Islam—constitute a large part of the global religious landscape, with more than half the world's population following them. However, limiting ourselves to studying these alone conceals from us the richness of human religious experience and the diversity of ways of thinking about the sacred. Understanding this diversity is necessary for any serious researcher into the question of God and religion.

Inadequate responses to avoid

From some believers:

"The Abrahamic religions are the only true religions, and the rest are paganisms." This response assumes what should be investigated. The question is not "which religions are true?" but "why do we study the diversity of religious thought?" Even if a person believes their religion is true, understanding other religions helps them understand their own faith more deeply and shows them the uniqueness of their religious experience.

"Other religions are mere philosophies, not true religions." This is a narrow definition of religion. Buddhism, Hinduism, and Taoism have temples, rituals, sacred texts, and millions of followers who live deep spiritual experiences. Considering them "mere philosophies" ignores the clear religious dimension within them.

"It's sufficient to know that God is one, and the rest are details." This is a reductive oversimplification. The question about the nature of God and His relationship to the world and humanity has very diverse answers across religions. The Hindu concept of "Brahman" differs radically from the concept of a personal God in Abrahamic religions, and this difference has profound implications for understanding existence, ethics, and salvation.

From some secularists:

"All religions are similar in essence." This is a false generalization. Religions differ radically in their fundamental concepts: God (personal/impersonal/non-existent), salvation (by faith/works/knowledge/extinguishing desire), and the afterlife (heaven and hell/reincarnation/nirvana). The differences are not superficial but fundamental.

"Eastern religions are more tolerant and peaceful." This is excessive romanticism. History shows that all religious traditions—Eastern and Western—have witnessed periods of tolerance and periods of intolerance. Religious wars in Asia and the persecution of minorities in some Buddhist countries all show that the problem is not in "East" or "West" but in human nature.

"We study other religions only for general cultural knowledge." This diminishes the importance of the subject. Studying religious diversity is not a cultural luxury but a necessity for deeper understanding of the phenomenon of religion itself and the nature of the human search for meaning.

Why these responses are inadequate

They all fail to grasp the true epistemological value of studying religious diversity. The question is not about "which religion is better?" or "do we need to study other religions?" but about the cognitive richness we lose when we confine ourselves to one tradition.

Serious positions in this debate

First, the position of "conceptual diversity enriches understanding." Non-Abrahamic religions raise concepts and questions that do not appear with the same clarity in the Abrahamic tradition:

- The concept of impersonal God: In Advaita Hinduism, "Brahman" is not a personal God who hears and responds, but the absolute existence that transcends attributes. This opens deep philosophical discussion about the nature of the Absolute.

- Religion without a creator God: Original Buddhism neither affirms nor denies the existence of a creator God, focusing on ending suffering. This raises the question: can there be religion in the full sense without God?

- Reincarnation and karma: Common concepts in Indian religions that present a completely different view of divine justice and the meaning of life and death.

Second, the position that "comparison reveals particularity and universality." When we study religions comparatively, we discover:

- What is universal: Nearly all religions deal with questions of meaning, death, ethics, and the sacred. This points to something deep in human nature.

- What is particular: Strict monotheism in Islam, the Trinity in Christianity, the chosen people in Judaism—all are particular concepts understood more deeply when compared with others.

Third, the position that "diversity shows the limits of religious language." When we see how different cultures express the sacred in very divergent ways, we realize that human language is limited in describing the Absolute. This calls for epistemological humility.

Fourth, the position that "civilizational dialogue is a contemporary necessity." In a globalized world, ignorance of other religions leads to misunderstanding and conflicts. Understanding how a Buddhist or Hindu thinks about the sacred is necessary for peaceful coexistence and constructive dialogue.

Where we stand in this debate today

Contemporary academic studies in philosophy of religion transcend traditional boundaries. Philosophers like John Hick and Ninian Smart have developed approaches for studying religions comparatively without reducing them. Modern approaches study:

- Cognitive structures: How does each religious culture build its own epistemological system?
- Religious experience: What are the similarities and differences in mystical experiences across religions?
- Language and symbol: How do different religions use language and symbols to point to what transcends language?
