In Sinclair Lewis's "It Can't Happen Here," the author explores the complex relationship between religion, power, and political freedom in America. He suggests that the nation's strength is rooted in a belief in God, which shapes its moral landscape. This belief imposes certain restrictions, particularly in public roles, where adherence to specific religious standards becomes a requirement for participation in society.

Lewis highlights a paradox of freedom, where absolute religious liberty is guaranteed but simultaneously limited by exclusionary measures against those who do not conform to certain beliefs. This delineates a troubling discrepancy in the notion of freedom, raising questions about the true nature of inclusivity and the consequences of intertwining faith with civic responsibility.
