Who are the Christian Nationalists in the American political landscape? And where are they heading? In October 2023, the US House of Representatives elected Mike Johnson, a White Christian Nationalist, to the office of Speaker of the House. In his paper for Hambach Democracy Dialogue, Philip Gorski, Professor of Sociology and Religious Studies at Yale University, analyses what this unexpected elevation tells us about the current state of the Republican Party. Laying out the history, religion and culture of White Christian Nationalism, he explains what it looks like today, how spiritual it has turned, and how it has seeped out into the secular culture.
