This article critically evaluates the perception of religious exclusivism in reformist epistemology through thinkers such as William P. Alston and Alvin Plantinga. The increasing prominence of religious diversity in modern life calls into question the epistemic equality of different religions' understandings of truth. While Alston and Plantinga argue that it is not irrational for a believer to think that their own religion possesses a unique truth compared to others, criticisms directed at this view reveal that the epistemic foundations of exclusivism are weak. The article questions whether religious exclusivism is a rational choice and discusses the impact of the epistemic equality brought about by religious diversity on the uniqueness of beliefs.
