The phrase “Christ is King” isn’t new — it’s sometimes used by Christians to refer to the belief that Jesus’s divine rule goes beyond that of earthly leaders. But the phrase has recently become “a kind of rallying cry for Christian supremacy,” historian Kristin Kobes Du Mez, author of Jesus and John Wayne: How White Evangelicals Corrupted a Faith and Fractured a Nation, told Truthout.

Over the last few years, the slogan has spread from far right provocateurs like Nick Fuentes to Trump’s cabinet and the military. In February, Secretary of Defense Pete Hegseth used the phrase at a convention of the National Religious Broadcasters, galvanizing Christian nationalists’ thirst for authoritarian rulers whose Jesus is defined by militant masculinity — more like a crusader or cowboy than the peace-loving, “sacrificial lamb” celebrated on Easter, who was executed for challenging the hierarchies of empire.

Along the way, the phrase has become a dog whistle for antisemitism, and it’s often combined with other Christian nationalist “holy war” rhetoric that has been spiking since the U.S. and Israel attacked Iran on February 28.
