In convos about Christian nationalism, it's important to define terms clearly.
"Christian nationalism" is a specific ideology that ties the future of the Church to the future of the State. It overlaps w/ secular nationalism but has incredibly toxic implications for gospel.
Some folks might say, "Well, I'm a Christian & I think we should prioritize America 1st over global concerns. Does that make me a Christian nationalist?"
The answer is a strong... maybe.
To know if you're ascribing to Christian nationalism of simple political nationalism, you'll need to interrogate your relationship btwn your nation & practice of your faith.
This will be extremely hard to do especially if you've been discipled in American evangelicalism in the last 40 years. Rhetorically speaking, we have conflated God & country to extent that it's hard to know where one stops & other begins.
Here's an example: In early 2000s, I had an ESL student from Bavaria. He was devout Lutheran & wanted to go to church for Easter. But when he got there, he saw an American flag on platform & was so disturbed that he left the service. He told me about it in class next day.
