One True God

This monograph presents a sociological analysis of religious monopolies and their consequences throughout history. Stark examines how exclusive monotheistic claims - the assertion that only one deity exists and all others are false - have shaped religious competition, persecution, and social conflict across cultures and epochs.

The work challenges conventional wisdom about religious pluralism and tolerance. Where many scholars assume that religious diversity naturally promotes peaceful coexistence, Stark argues that monotheistic exclusivity inherently generates conflict. He traces this pattern from ancient Judaism through early Christianity to Islam, demonstrating how claims to possess the "one true God" create zero-sum competition between faiths. The author employs quantitative historical data alongside case studies to support his thesis that monotheistic religions, by their very nature, cannot genuinely tolerate rival truth claims.

Stark's methodology combines rational choice theory with historical sociology. He treats religious groups as firms competing in a marketplace of beliefs, where monotheistic "products" demand exclusive loyalty. This economic model explains why polytheistic systems historically showed greater tolerance - multiple gods could coexist without logical contradiction. However, once a religion claims exclusive access to divine truth, it must necessarily view other faiths as not merely different but false and dangerous.

The monograph engages critically with secularization theorists who predicted religion's decline and with pluralism advocates who see diversity as inherently beneficial. Stark contends that religious monopolies, despite their tendency toward intolerance, often display greater vigor and growth than pluralistic systems. He examines how state-supported religious monopolies differ from market-dominant ones, arguing that genuine religious vitality emerges from competition rather than coercion.

This work contributes to debates about religious freedom, tolerance, and social conflict by providing empirical grounding for discussions often dominated by theological or philosophical arguments. Stark's analysis suggests that appeals for religious tolerance must reckon with the inherent logic of monotheistic truth claims. His findings have implications for understanding contemporary religious tensions and for policies promoting religious harmony in diverse societies. The monograph stands as a significant contribution to the sociology of religion, offering a provocative thesis about the relationship between theological claims and social outcomes.
