What Is Christian Nationalism? Few ideas are as emotionally charged or as widely misunderstood as Christian nationalism. To some, it represents the preservation of moral order and divine blessing on a nation once founded on Christian principles. To others, it signals a threat to democracy, religious freedom, and the separation of church and state. At its core, Christian nationalism is an ideology that fuses religious identity with national identity. It asserts that the nation often implicitly defined by its dominant ethnic or cultural group is divinely chosen, and that its laws, leaders, and public life should reflect a specific vision of Christianity. This is not the same as Christianity itself. Christianity is a global faith centered on Jesus Christ, practiced in countless cultures and political systems. Christian nationalism, by contrast, is a political theology a way of imagining how God relates to a specific nation and its destiny. It makes faith serve a civic purpose: defining who belongs, what values should be enforced, and how the state should act. The distinction between personal faith and political religion is crucial. A Christian may pray for their nation and hope its leaders act justly that is patriotism. But a Christian nationalist believes the nation must be Christian, and that those who do not share this identity are less legitimate participants in its life. This ideology has appeared in many forms. In the United States, it has drawn on Puritan "city upon a hill" imagery, the moral language of the American Revolution, the pro-slavery theology of the Confederacy, the Cold War's "Under God" campaigns, and the modern Religious Right. In Europe and Latin America, Catholic and Orthodox versions have shaped politics and identity in similar ways. Christian nationalism often emerges in moments of anxiety when people feel their cultural or religious influence slipping. It promises restoration: a return to "biblical values," "God's order," or "the way things used to be." It frames political struggles as moral and even cosmic battles, blurring the line between civic disagreement and spiritual warfare. Understanding Christian nationalism means studying both its emotional appeal the desire for belonging, order, and divine favor and its social consequences: exclusion, division, and at times, violence.
