The U.S. Supreme Court is redrawing the boundary between church and state. In several major rulings, the court came down on the side of the free exercise clause of the First Amendment, provoking critics to charge that the conservative justices are obliterating an important foundation of American life, the separation of church and state. It is the unresolvable conflict in our politics, and today's combatants draw on the founding generation for ammunition for their arguments. In this episode, historian Katherine Carté tries to untangle the conflicting meanings of religious liberty at the center of the legal and cultural struggles.
