In The Triumph of Christianity Redescribed, Éric Rebillard argues that the appearance of Christian signs and practices in the Roman Empire has long been misunderstood. Rather than marking a rapid wave of conversions or the triumph of belief, the spread of Christian signs reflected a more complex and fluid religious landscape. Rebillard offers a striking new account of how Christianity took hold, not through adherence to doctrine or formal membership in a church, but through a gradual diffusion of signs and practices. Drawing on cognitive science, anthropology, and theories of religious mobility, he shows how individuals across the ancient Mediterranean experimented with religious symbols: adopting some, abandoning others, and often blending them without concern for consistency. Rebillard maps out a world where religious affiliation was provisional, situational, and rarely exclusive. The Triumph of Christianity Redescribed challenges the idea that Christianity's rise was a straightforward story of growth, mission, or hegemony. By replacing a triumphalist narrative with one attuned to ambiguity, resilience, and the everyday realities of religious life in late antiquity, Rebillard offers scholars and general readers alike a richer, more accurate account of how Christianity spread—and what that spread actually meant.
