We tend to think of Christian nationalism, the political ideology based on the belief that the country’s authentic identity lies in its Christian roots and in the perpetuation of Christian privilege, as having burst upon the scene to accompany and facilitate the rise of Donald Trump. But as Philip Gorski and Samuel Perry explain in The Flag and the Cross, Christian nationalism—white Christian nationalism, to be more accurate, since the ideology has no place for nonwhites—is “one of the oldest and most powerful currents in American politics.” They trace it back to the New England Puritans’ wars against the indigenous groups who dared to stand in the way of the claim by self-described chosen people to their new Promised Land, and follow it through the Lost Cause of a post–Civil War South destined to “rise again”—a Christological narrative of crucifixion and redemption “crucial to understanding contemporary claims of Christian victimhood and vengeance among white Christian nationalists.” The drive for western expansion, aptly known as Manifest Destiny, was widely understood as part of a divine plan handed to those who would “civilize” an entire continent.

According to a recent Pew Research poll, 60 percent of Americans believe the country was founded to be a Christian nation, and nearly half (including 81 percent of white evangelicals) think it should be one today. Whether that has changed over the course of US history is beside the point: what’s new is the contemporary political and social salience of Christian nationalism. As mainline Protestantism has faded, David Hollinger observes in Christianity’s American Fate,

Christianity has become an instrument for the most politically, culturally, and theologically reactionary Americans. White evangelical Protestants were an indispensable foundation for Donald Trump’s presidency and have become the core of the Republican Party’s electoral strength. They are the most conspicuous advocates of “Christian nationalism.”…Most of Christianity’s symbolic capital has been seized by a segment of the population committed to ideas about the Bible, the family, and civics that most other Americans reject.

How did this happen? Gorski and Perry, Hollinger, and David Sehat in This Earthly Frame agree that the answer lies in white evangelicals’ response to the profound cultural changes the country experienced during the second half of the twentieth century. That may sound obvious, but with varied approaches, these three books offer insights that are both illuminating and alarming.

The Flag and the Cross deals most directly with white Christian nationalism as a political force. The authors are sociologists, Gorski at Yale and Perry at the University of Oklahoma. Their conclusions are based largely on data from surveys they devised and conducted from 2019 through 2021. At the heart of their analysis is a “Christian nationalism scale” based on respondents’ level of agreement with seven statements that include “The success of the United States is part of God’s plan” and “The federal government should advocate Christian values.”

This scale is one axis on a series of charts showing how Christian nationalist beliefs correlate with attitudes about life in today’s United States. For example, Gorski and Perry asked people to estimate “how much discrimination” whites and Blacks would experience in the coming year. Black respondents, no matter where they fell on the Christian nationalism scale, offered similar predictions: low for whites and high for Blacks. For white respondents, the results were dramatically different: the higher on the Christian nationalist scale they were, the greater their expectation of antiwhite discrimination and a correspondingly lower expectation of discrimination against Blacks. “White Christian nationalists sincerely believe that whites and Christians are the most persecuted groups in America,” the authors conclude. This is a belief, they emphasize, with political consequences: “White Christian nationalism is a ‘deep story’ about America’s past and a vision of its future. It includes cherished assumptions about what America was and is, but also what it should be.”
