What does it actually mean to call America a “Christian nation”? Is that identity measured by the religious language of its leaders, the beliefs of its citizens, or by something far more demanding?

In this episode of The Empire: A 250 Year American Story, we return to one of the central questions running through our exploration of American history: Is America a Christian nation? As the founding generation passed away, Christianity became increasingly intertwined with American identity. The Second Great Awakening transformed the religious landscape, political leaders spoke more openly about God, and Americans increasingly imagined their country as a nation with a special divine purpose.

But beneath that growing religious confidence were some profound contradictions. The same nation that spoke of providence and Christian civilization was expanding westward at enormous human cost. Americans who celebrated prayer, faith, and biblical values also wrestled with Native American removal, slavery, racial oppression, and a Civil War in which both sides claimed that God favored their cause.

That contradiction raises a more challenging way of thinking about America’s Christian identity. Perhaps the most important question is not how often a nation mentions God, how many churches it contains, or whether its leaders use Christian language. Perhaps the better test is found in the biblical standards of justice, mercy, humility, and compassion—particularly in how a society treats those who are weak, forgotten, oppressed, or powerless.

From Alexis de Tocqueville’s observations of American religion to the spiritual crisis of Abraham Lincoln during the Civil War, this episode explores the widening gap between claiming Christian identity and actually practicing Christian values. It is a journey through faith, politics, slavery, national ambition, war, and the difficult question of what God might actually require of a nation that claims His name.
