A Christian nationalist is a person who believes that the United States was founded as a Christian nation and should maintain a strong Christian identity in its laws, government, and culture. [1][2] Christian nationalists typically seek to promote Christian values and influence in the political sphere, often with the goal of shaping the country's laws and policies to align with their interpretation of Christian doctrine.[1][2]

In contrast, a Christian Democrat is a political orientation common in Europe that emphasizes social justice, subsidiarity, and the role of the church in society, but does not necessarily seek to establish a Christian state or impose Christian doctrine through the government.[3] Christian Democrats generally believe in the separation of church and state and advocate for policies that support the common good and the dignity of the human person, rather than explicitly promoting a Christian nationalist agenda.[3]

The key difference is that Christian nationalism is a political ideology focused on establishing a Christian identity for the nation, while Christian Democracy is more focused on applying Christian social teachings to the political realm without necessarily seeking to create a Christian state.[3]
