If you take out the circular cross-references in your definitions, they sound the same:

> 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

> Christian Democracy is more focused on applying Christian social teachings to the political realm

Christian doctrine is all about "the common good and the dignity of the human person." That encompasses both the stuff secular liberals like (such as "provide for the poor") and the stuff secular liberals hate (such as "human life has dignity at conception" or "sex is for procreation").

I think there is a clear line to be drawn when you talk about a "Christian state"--a state that restricts the right of religious minorities to freely practice their religion. That, I think could properly be called "Christian nationalism." But very few people want that.
