Taking America Back for God conclusively reveals that understanding the current cultural and political climate in the United States requires reckoning with Christian nationalism. Christian ideals and symbols have long played an important role in public life in the United States, but Christian nationalism demands far more than a recognition of religious heritage. At heart, Christian nationalism fights to preserve a particular kind of social order, an order in which everyone—Christians and non-Christians, native-born and immigrants, whites and minorities, men and women—recognizes their “proper” place in society. The first comprehensive empirical analysis of Christian nationalism in the United States, Taking America Back for God illustrates the scope and tremendous influence of Christian nationalism on debates surrounding the most contentious social issues dominating American public discourse. Drawing on multiple sources of national survey data collected over the past several decades and in-depth interviews, Whitehead and Perry document how Christian nationalism radically shapes what Americans think about who they are as a people, what their future should look like, and how they should get there. Regardless of Americans’ political or religious characteristics, whether they are Ambassadors, Accommodators, Resisters, or Rejecters of Christian nationalism provides powerful insight into what they think about immigration, Muslims, gun control, police shootings, atheists, gender roles, and many other political issues—even who they want in the White House. Taking America Back for God convincingly shows how Christian nationalists’ desire for political power, rigid social boundaries, and hierarchical order creates significant consequences for all Americans.
