A Treatise on Relics

About the book

"A Treatise on Relics" by Jean Calvin is a theological work written in 1543. Calvin systematically challenges the authenticity of Christian relics venerated across Europe, cataloging dubious artifacts from dozens of cities. He documents impossible duplications—saints with multiple bodies, excessive quantities of the Virgin Mary's milk, and Christ's multiplied belongings. Through detailed examination, Calvin argues these objects encourage idolatry rather than genuine faith, urging Christians to abandon relic worship entirely and warning readers against venerating what might actually be thieves' bones or common objects.
