Christian Nationalism and Civil Religion

Christian nationalism and American civil religion are overlapping but distinct ways of connecting religion, national identity, political authority, historical memory, and civic belonging. The distinction is central to a large body of scholarship on religion and American public life. Civil religion has traditionally referred to a shared national religious or quasi-religious framework expressed through public rituals, founding documents, presidential rhetoric, holidays, monuments, sacrifice, providence, and ideals such as liberty and equality. Christian nationalism more specifically links American identity and political order with Christianity and may define national belonging in explicitly Christian terms.

Robert N. Bellah's influential 1967 formulation described American civil religion as a religious dimension of national life that existed alongside, rather than simply within, institutional Christianity. His argument helped establish civil religion as a major field of sociological and historical research. The sources collected here trace how scholars have subsequently debated whether civil religion provides a broadly inclusive civic language, preserves Protestant assumptions, supports national cohesion, legitimizes political authority, or can develop into more exclusionary forms of religious nationalism.

Civil Religion and Christian Nationalism as Distinct Concepts

A major theme in recent scholarship is the need to distinguish Christian nationalism from civil religion, conventional Christian belief, religious conservatism, patriotism, and ordinary religious participation in politics. Studies in the source collection examine Christian nationalism as a cultural and political framework that joins Christianity with ideas about American national identity, while civil religion can operate through broader references to God, providence, sacrifice, founding ideals, national destiny, sacred history, and civic ritual.

Recent scholarship directly compares Christian nationalism with pluralist civil religion and strict secularism as different models of national identity. Amy E. Black and Douglas L. Koopman, for example, describe Christian nationalism, strict secularism, and pluralist civil religion as competing approaches to religion in American public life. Their work emphasizes that civil religion can change as the United States becomes more religiously diverse and more secular.

Public attitudes are similarly more complicated than a simple division between religious and secular Americans. Pew Research Center surveys distinguish among support for Christianity's cultural influence, government promotion of Christian values, an officially Christian nation, and church-state separation. In Pew's 2024 survey, most Americans supported church-state separation, while views differed substantially over whether government should promote Christian moral values or formally identify the country with Christianity.

Origins and Development of American Civil Religion

American civil religion draws on several historical traditions rather than a single founding doctrine. The source material traces its development through Puritan covenant theology, revolutionary political thought, founding documents, presidential language, the Civil War, national holidays, monuments, military sacrifice, and later political conflicts.

The Puritan idea of a covenant community, especially John Winthrop's description of Massachusetts Bay as a community watched by the world, later became part of narratives portraying America as a chosen or providential nation. The phrase commonly remembered as the “city upon a hill” has repeatedly been adapted to national political purposes far beyond its seventeenth-century setting.

The Declaration of Independence, Constitution, and Bill of Rights subsequently acquired an almost canonical position within American civic culture. Although these documents differ considerably in their treatment of religion, later generations incorporated them into a national sacred story involving founding fathers, constitutional liberty, providence, sacrifice, and national mission.

George Washington's inaugural speeches and Thanksgiving proclamations helped establish patterns in which presidents invoked providence without formally establishing a national church. Later presidents continued this tradition, adapting civil-religious language to war, economic crisis, national mourning, political conflict, and social reform.

Presidential Rhetoric and Sacred National Narratives

Presidents have served an important symbolic function in American civil religion. Inaugural addresses, national prayers, memorial speeches, Thanksgiving proclamations, wartime addresses, and statements following national tragedies frequently place political events within narratives of providence, moral obligation, sacrifice, renewal, and national purpose.

George Washington's first inaugural established an early precedent for invoking divine providence while addressing a religiously diverse republic. Thomas Jefferson combined religious liberty and providential language, while Abraham Lincoln transformed civil-religious rhetoric during the Civil War.

Lincoln's Gettysburg Address and Second Inaugural became especially influential examples of what scholars often describe as prophetic civil religion. Rather than simply claiming divine approval for the nation, Lincoln interpreted national suffering and slavery through themes of judgment, sacrifice, repentance, equality, and reconciliation.

Franklin Roosevelt similarly invoked religious language during the Great Depression and World War II. His D-Day prayer publicly joined military action, national responsibility, and religious faith. Dwight Eisenhower's Cold War rhetoric further linked faith, freedom, national unity, and resistance to communism.

Scholars have continued to examine civil-religious rhetoric from Ronald Reagan through Barack Obama and Donald Trump, asking whether presidential religious language unifies citizens, deepens partisan divisions, sanctifies national power, or provides a moral vocabulary through which political authority can itself be criticized.

God, Nation, and the Cold War

The Cold War was a particularly important period in the institutionalization of religious language in American civic identity. Political leaders frequently contrasted a religious United States with officially atheistic communism, strengthening the association among faith, freedom, patriotism, capitalism, and national purpose.

Congress added the words “under God” to the Pledge of Allegiance in 1954 and adopted “In God We Trust” as the national motto in 1956. These measures became enduring elements of American public symbolism. The source collection includes congressional records, presidential statements, and later scholarship examining the political and religious context of these changes.

These Cold War developments illustrate one of the persistent questions surrounding civil religion: whether broadly religious national language can remain inclusive or whether it implicitly privileges particular religious traditions.

The Pledge, Flags, Monuments, and Sacred Civic Space

Civil religion is expressed not only through political ideas but also through ceremonies, objects, places, and rituals. The American flag, Pledge of Allegiance, national anthem, war memorials, presidential inaugurations, Thanksgiving celebrations, cemeteries, monuments, and historic sites can operate as forms of sacred civic symbolism.

The Pledge has been especially significant because it combines patriotism, national unity, ritual repetition, and the phrase “under God.” Court disputes involving the Pledge demonstrate the continuing constitutional tension between public religious language and government neutrality toward religion.

National memorials also function as sites of civic pilgrimage and collective memory. The Lincoln Memorial, Washington Monument, Gettysburg, Arlington National Cemetery, and Martin Luther King Jr. Memorial connect political ideals with sacrifice, death, national memory, and moral narratives about what the United States represents.

Such symbols are not interpreted uniformly. Protest involving the flag or national anthem, for example, can generate disputes over whether patriotism requires reverence for national symbols or whether criticism of the nation represents another form of commitment to its professed ideals.

Race and the Boundaries of National Belonging

Race is a major theme throughout the scholarship on both Christian nationalism and civil religion. Research in the source collection examines relationships among Christianity, Whiteness, racial identity, immigration, national belonging, racial inequality, policing, interracial marriage, political tolerance, and perceptions of who counts as a “real” American.

Some scholarship describes American civil religion as containing competing universalistic and tribal strands. Universalistic traditions emphasize ideals such as equality, citizenship, liberty, and constitutional rights. Tribal traditions historically connected American identity more closely with Protestantism, European ancestry, Whiteness, or culturally dominant religious traditions.

Research on Christian nationalism similarly investigates whether definitions of national belonging are shaped by racial and ethnoreligious boundaries. The collected studies address White Christian nationalism, perceptions of racial inequality, immigration attitudes, xenophobia, policing, and demographic threat.

At the same time, scholars increasingly caution against treating Christian nationalism as a completely uniform phenomenon. Research examines differences among racial groups, denominations, political traditions, and forms of Christian nationalist belief, as well as disputes over how commonly used survey measures should be interpreted.

Civil Rights and Prophetic Civil Religion

American civil religion has also supplied language for criticizing the United States rather than merely celebrating it. This tradition is particularly visible in the civil rights movement.

Martin Luther King Jr. repeatedly drew together biblical imagery, constitutional ideals, the Declaration of Independence, democratic equality, and national history. His rhetoric portrayed America's founding promises as moral commitments against which the country's actual treatment of Black Americans should be judged.

“Letter from Birmingham Jail,” the March on Washington address, “Beyond Vietnam,” and King's final speeches exemplify a prophetic approach to national identity. Instead of assuming that American policies represented divine purposes, this approach demanded that political institutions answer to religious and democratic standards.

This distinction between priestly and prophetic civil religion is important throughout the literature. Priestly civil religion tends to affirm, unite, commemorate, and legitimize. Prophetic civil religion emphasizes judgment, repentance, reform, justice, and the possibility that the nation has violated its own proclaimed ideals.

Religion, War, Sacrifice, and National Mission

War has repeatedly strengthened civil-religious themes surrounding sacrifice, providence, martyrdom, national destiny, and moral mission. From the Civil War through the world wars, Cold War, Vietnam, and post-September 11 conflicts, political leaders have used religious language to interpret national suffering and military service.

The Civil War produced some of the most enduring examples. Lincoln's rhetoric placed the war within a moral drama involving slavery, judgment, sacrifice, and national rebirth.

World War I encouraged extensive cooperation among religious, patriotic, civic, and military organizations and contributed to a sacralized language of national loyalty. World War II and the Cold War further associated American political identity with religious belief and opposition to totalitarianism.

After the September 11 attacks, phrases such as “God Bless America” and rituals of national mourning became prominent again. Scholarship on this period asks whether civil religion helped citizens process collective trauma or whether it could also sanctify military action and discourage criticism of national policy.

Immigration, Religious Difference, and National Boundaries

Debates about immigration reveal how religious and national identities overlap. Several sources examine attitudes toward immigrants, Muslims, religious minorities, and demographic change.

Research on Christian nationalism has found that beliefs about a Christian national identity can interact with perceptions of cultural and demographic threat. Other research distinguishes religious ingroup favoritism from direct hostility toward outgroups and emphasizes that religion's political effects depend on social and political context.

The increasing religious diversity of the United States raises a related challenge for civil religion. Civic language rooted primarily in Protestant assumptions may become less capable of representing a population that includes Catholics, Jews, Muslims, Hindus, Buddhists, members of other religious traditions, and a growing number of religiously unaffiliated citizens.

Contemporary scholarship therefore asks whether civil religion can evolve into a genuinely pluralistic civic tradition without erasing religion from public life or giving one religion privileged political status.

Democracy, Political Tolerance, and Pluralism

Another major strand of research examines how religious-national identity relates to democratic norms, political tolerance, civil liberties, voting rights, treatment of political opponents, and acceptance of religious diversity.

Studies in the collection examine whether Christian nationalist beliefs correlate with unequal application of rights to different social groups, willingness to tolerate political or religious opponents, support for leaders violating democratic norms during emergencies, and attitudes toward voting access.

These relationships remain subjects of active scholarly debate. Researchers disagree about how broadly Christian nationalism should be defined, what commonly used survey questions actually measure, and whether some studies conflate Christian nationalism with conservative religious belief, patriotism, partisan identity, or other related concepts.

A central issue is therefore conceptual as well as political: scholars must distinguish among religious devotion, public Christianity, nationalism, civil religion, partisan identity, authoritarian attitudes, racial identity, and specific policy preferences rather than treating them as interchangeable.

Religious Partisanship and Political Polarization

Religion and partisan identity have become increasingly intertwined in modern American politics. Research represented in the source material examines social sorting, evangelical political identity, polarization, and the possibility that political affiliation can reshape religious identity as well as the reverse.

This scholarship complicates simple accounts in which religious beliefs independently produce political preferences. Political communities can influence how individuals understand their religious identities, while religious institutions can reinforce political affiliations and social networks.

Christian nationalism therefore operates within a broader environment of partisan polarization. Individuals may interpret religious symbols, national history, racial issues, church-state disputes, and patriotic rituals differently depending on political identities and group attachments.

Civil religion itself can become polarized when supposedly shared national symbols cease to carry shared meanings.

Church-State Relations and Religious Liberty

The relationship between religion and government has been contested throughout American history. The First Amendment prohibits establishment of religion while protecting free exercise, creating an enduring debate over the legitimate place of religion in public institutions.

James Madison's “Memorial and Remonstrance Against Religious Assessments,” Jefferson's Virginia Statute for Religious Freedom, and Jefferson's 1802 letter to the Danbury Baptists became foundational texts in later debates about religious liberty and church-state separation.

Supreme Court cases concerning public-school prayer, Bible reading, government aid to religion, and religious expression further defined the constitutional boundaries of public religion.

Christian nationalist arguments sometimes appeal to the country's Christian history as justification for a stronger governmental recognition of Christianity. Critics respond by emphasizing constitutional disestablishment, religious pluralism, liberty of conscience, and equal citizenship.

Civil religion occupies a different conceptual space because public invocations of God or providence have historically existed alongside formal disestablishment. The constitutional significance of particular practices nevertheless remains disputed and depends on their specific governmental setting.

Christian Nationalism, Secularism, and Pluralist Civil Religion

One of the clearest contemporary frameworks represented in the source material contrasts three broad approaches to national identity: Christian nationalism, strict secularism, and pluralist civil religion.

Christian nationalism links the nation more specifically to Christianity and can treat Christianity as central to legitimate American political identity. Strict secularism seeks a sharper exclusion of religious ideas from public political life. Pluralist civil religion attempts to preserve shared civic ideals and moral language while allowing participation by citizens of many religions and none.

Black and Koopman's recent work develops this three-part distinction explicitly, presenting civil religion as a potentially shared civic framework in a religiously diverse society. This is their normative interpretation rather than an uncontested scholarly conclusion.

The broader literature shows why the distinction remains difficult. Civil religion has historically drawn heavily from Protestant language and assumptions, while Christian nationalism can appropriate many of the same symbols, including providence, national chosenness, biblical imagery, the flag, founding documents, military sacrifice, and the idea of a special American mission.

The boundary between the two therefore depends not simply on whether religious language appears in public life but on how national identity, political authority, religious membership, citizenship, pluralism, and criticism of the nation are understood.

Religious Nationalism versus Prophetic Civil Religion

A recurring distinction in the source collection separates religious nationalism from prophetic civil religion.

Religious nationalism tends to identify the nation, its people, or its political order with a particular religious tradition and may portray national interests as possessing divine sanction. It can define insiders and outsiders through religious or ethnoreligious boundaries.

Prophetic civil religion instead uses religious and civic ideals to evaluate the nation critically. Figures such as Lincoln and King invoked religious language not merely to sanctify American power but to demand repentance, equality, justice, reconciliation, and fulfillment of constitutional promises.

This distinction helps explain why religious language in politics cannot automatically be classified as Christian nationalism. The same biblical or providential vocabulary can perform substantially different political functions depending on whether it identifies the nation with divine authority, supports exclusionary membership claims, encourages self-criticism, or appeals to principles applicable across religious boundaries.

Continuing Scholarly Debates

The collected literature demonstrates that neither Christian nationalism nor civil religion has a single universally accepted definition.

Researchers debate how Christian nationalism should be measured, whether standard survey scales combine several distinct ideas, how race and partisanship interact with religious-national beliefs, and how Christian nationalism differs across demographic and denominational groups. The source collection includes work explicitly questioning assumptions within parts of the Christian-nationalism literature and urging greater conceptual precision.

Civil religion presents similar definitional problems. Scholars have debated since Bellah whether it represents an independent religious system, a form of nationalism, a collection of civic rituals, a political ideology, a shared moral language, or a symbolic framework whose meaning changes across historical periods.

The literature also disagrees about whether civil religion primarily unifies or excludes. Historical research demonstrates that supposedly universal national traditions have often reflected Protestant, racial, gendered, or imperial assumptions. Yet other scholarship emphasizes the capacity of civil-religious language to broaden citizenship, support civil rights, criticize state power, and provide common symbols across religious differences.

Conclusion

Christian nationalism and civil religion share symbols, stories, religious vocabulary, and claims about national identity, but the source material consistently treats them as analytically distinguishable rather than synonymous.

American civil religion developed through founding narratives, presidential rhetoric, providential language, war and sacrifice, holidays, monuments, constitutional ideals, national rituals, and public memory. At different moments it has been used to unite citizens, legitimize authority, criticize injustice, mourn national tragedies, define national mission, and articulate ideals extending beyond any single denomination.

Christian nationalism more explicitly connects Christianity with the political identity and character of the nation. Contemporary research examines how such beliefs intersect with race, immigration, partisanship, political tolerance, democracy, gender, national belonging, and attitudes toward religious minorities.

The central tension running through the literature is therefore not simply between religion and secularism. It concerns competing answers to a deeper question: what makes Americans members of the same political community? The historical record includes religious nationalism, secular constitutionalism, pluralist civil religion, prophetic religious criticism, and many combinations of these traditions.

The distinction remains especially important as the United States becomes more religiously diverse and politically polarized. Civil-religious symbols that once appeared broadly shared can acquire sharply different meanings, while Christian nationalism itself varies across communities and historical contexts. Understanding the relationship between the two requires attention to history, race, constitutional law, political identity, theology, symbolism, public opinion, and the changing boundaries of American citizenship.
