The Christian Religion: An Enquiry

Robert Green Ingersoll was the most famous agnostic in American history, and this book is his most systematic assault on Christian theology. Written in the late nineteenth century, it treats religious claims the way a lawyer treats evidence: with relentless cross-examination. Ingersoll doesn't merely reject faith he interrogates the Bible itself, pointing out that the Good Book sanctions slavery, commands death for blasphemers, and treats women as property. He contrasts the portrait of a loving God with scripture's blood-soaked pages, and asks simply: is this the work of divine wisdom or human barbarism? The book crackles with Ingersoll's legendary oratory, translated into precise, devastating prose. Yet this is more than polemic. At its core lies a profound claim: that genuine morality must spring from human reason and experience, not from ancient texts dictated by fear. Ingersoll argues that justice exists independent of doctrine, that goodness needs no divine warrant. The questions he raises about faith, reason, and the sources of moral authority remain urgent today. For readers who enjoy intellectual history, the religion-and-science debates, or the great tradition of American skepticism.
