In Founding Sins, Joseph Moore examines the forgotten history of the Covenanters, America's first Christian nationalists. He explores how they profoundly shaped American's understandings of the separation of church and state and set the acceptable limits for religion in politics for generations to come.

A penetrating account of the religious critics of American liberalism, pluralism, and democracy--from the Revolution until today "A chilling consideration of persistent mutations of American thought still threatening our pluralist democracy."--Kirkus Reviews (starred review) The conversation about the proper role of religion in American public life often revolves around what kind of polity the Founders of the United States envisioned. Advocates of a "Christian America" claim that the Framers intended a nation whose political values and institutions were shaped by Christianity; secularists argue that they designed an enlightened republic where church and state were kept separate. Both sides appeal to the Founding to justify their beliefs about the kind of nation the United States was meant to be or should become. In this book, Jerome E. Copulsky complicates this ongoing public argument by examining a collection of thinkers who, on religious grounds, considered the nation's political ideas illegitimate, its institutions flawed, and its church-state arrangement defective. Beholden to visions of cosmic order and social hierarchy, rejecting the increasing pluralism and secularism of American society, they predicted the collapse of an unrighteous nation and the emergence of a new Christian commonwealth in its stead. By engaging their challenges and interpreting their visions we can better appreciate the perennial temptations of religious illiberalism--as well as the virtues and fragilities of America's liberal democracy.
