This study contends that “Christian Nationalism” is an oxymoron, two words that combined form a contradiction. Christianity is a global religion that belongs to no specific nation. The United States Constitution rejects any law that establishes a national religion, Christian or otherwise.

Public media conversation has increasingly revolved around the growing political power of an American movement called “Christian Nationalism” and/or “White Christian Nationalism.” Christian Nationalism is not a new religion, denomination, or church in America; nor does it reflect new ideas about the relationship of Christianity and U.S. government. However, the movement has demonstrated a major surge in political power that has renewed debate about the Constitutional First Amendment, “Congress shall make no law respecting an establishment of religion.” Christian Nationalists are united primarily on one belief, that the U.S. is a “Christian nation,” a viewpoint that constitutional scholar Andrew Seidel calls The Founding Myth: Why Christian Nationalism Is Un-American (2019).
