Christian nationalism is no longer only a label applied by journalists or scholars. In 2026, conservative denominations including the Christian Reformed Church, Presbyterian Church in America, Orthodox Presbyterian Church, and Lutheran Church–Missouri Synod began or continued formal study of the subject. Christianity Today reported that the debate inside those churches includes a basic preliminary question: What exactly is being studied?

That question matters because the phrase is used for several different things. It can mean little more than Christians voting according to their convictions. It can describe a belief that Christianity helped shape American culture. It can refer to a government that promotes Christian values without establishing a church. At its strongest, it means that Christian identity should define authentic national membership and receive formal preference from the state.

Those positions are not identical. Treating them as one movement makes the label sound more precise than it is. Treating the phrase as meaningless, however, hides a real dispute about who belongs, which religion the government should favor, and how political power should enforce a national identity.

Ordinary Christian politics is not enough

A Christian who opposes abortion, supports refugees, favors school prayer, campaigns for prison reform, or votes according to a theological view is participating in politics as a religious citizen. Secular voters also bring moral convictions to public life. Religious motivation alone does not establish nationalism.

Nor does patriotism. A Christian can love a country, serve in its institutions, celebrate its achievements, and criticize its failures without believing that Christianity defines who counts as a real citizen. The important shift occurs when faith and national identity are joined so closely that the nation is thought to have a specifically Christian essence, mission, or rightful ruling culture.

That is why the adjective and noun both matter. “Christian” identifies the tradition used to define the nation. “Nationalism” gives the nation unusual moral priority and asks political institutions to protect its preferred identity. A view becomes recognizably Christian nationalist when the state is expected to preserve a Christian national character, not merely protect Christians’ equal freedom to argue, worship, and organize.

The surveys are measuring different thresholds

Public estimates vary because researchers do not all ask the same questions. PRRI’s 2025 American Values Atlas used five items about Christianity, American identity, and government. It classified 11 percent of Americans as adherents and 21 percent as sympathizers. Those categories describe scores on a battery of questions. They do not mean that every person adopted “Christian nationalist” as a personal label.

A Pew Research Center survey shows why wording changes the picture. In 2022, 45 percent of adults said the United States should be a Christian nation. Yet people meant strikingly different things by that answer. Among supporters, many described general moral guidance or a religious population, while smaller shares meant explicitly Christian laws. About half of supporters in an earlier linked survey still said the government should never declare an official religion.

So “Christian nation” can express cultural memory, demographic description, moral aspiration, or a program for state power. A poll that counts all four together will produce a broad estimate. A measure requiring government preference, Christian criteria for belonging, and religious control of law will produce a narrower one.

Recent scholarship makes the problem explicit. A 2026 Public Opinion Quarterly study found that Christian nationalist identities exist and are strongly related to a Christian nationalist worldview, but identification partly depends on how the group is defined. People are not only answering policy questions. They are also reacting to a contested identity label that supporters and critics describe differently.

Measurement criticism is part of the evidence

Researchers themselves disagree about the standard scales. Jesse Smith and George Yancey argued in a 2025 Review of Religious Research article that commonly used survey items do not always match the concept scholars claim to measure. Their alternative scale was designed to capture support for Christian nationalism more directly, and they called for some earlier conclusions to be reassessed.

That criticism should not be treated as proof that Christian nationalism is invented. It shows that broad questions such as whether the government should advocate Christian values can capture several motivations. One respondent may envision equal human dignity and public honesty. Another may want officeholders to pass a religious test. A valid measure has to distinguish influence by persuasion from identity enforced through government.

The same caution applies to correlations. If people with high scale scores are more likely to hold another political attitude, that does not mean every Christian conservative holds it. A statistical relationship describes groups, not the motives of each individual. Accusations of racism, authoritarianism, or theocracy require evidence about the person or proposal being discussed, not a label used as a shortcut.

The affirmative case is not always a call for theocracy

Some writers openly defend the term. In a 2026 First Things essay, R. R. Reno argues that nationalism can restore solidarity in a fragmented country and that Christianity can restrain nationalism with moral truth, human fallibility, and providence. His case is not simply that believers should vote. He argues that Christianity should shape the nation’s moral foundations and supplies the best form of national renewal.

This is a stronger and more useful position to examine than the claim that every public expression of faith is secretly theocratic. The affirmative case begins with real concerns: social distrust, loneliness, weak institutions, moral disagreement, and the loss of a shared story. It asks whether a historically Christian inheritance can support cohesion without requiring conversion or abolishing freedom of religion.

But calling Christianity a national foundation creates unanswered institutional questions. Which Christianity supplies the foundation? Catholic natural law, Reformed confessions, Pentecostal practice, Black church traditions, Christian liberalism, and Eastern Orthodoxy do not offer one political program. A government cannot privilege “Christianity” in the abstract. Officials, judges, school boards, or legislatures must decide which beliefs count and what preference means in practice.

Christian critics focus on the power to define Christianity

That problem also drives opposition from conservative Christians. In a 2026 Gospel Coalition essay, pastor Andrew Hopper argues that government power favorable to one church today can be used against it tomorrow. His objection is not that Christian convictions should disappear from public debate. It is that religious tests, blasphemy rules, or official promotion require the state to decide which version of Christianity deserves protection.

This concern is different from a secular demand that religious people leave their beliefs at home. It is an argument about jurisdiction. Churches preach, baptize, discipline members, and define doctrine. Governments protect rights, administer laws, and wield coercive authority. Once the government is charged with maintaining Christian identity, disagreements once settled by persuasion or church membership become questions for state power.

The risk is clearest for people already outside Christianity. A state may promise tolerance while still treating non-Christians as guests in someone else’s nation. Equal legal rights can coexist with unequal symbolic membership, but that arrangement is unstable. If being truly American is tied to being Christian, a Muslim, Jew, atheist, Hindu, or former Christian can obey every law and still be regarded as less fully part of the national “we.”

Five questions clarify the label

Instead of asking only whether a person is a Christian nationalist, ask what the proposed arrangement would do:

  • Is Christianity one contributor to public argument, or a required element of authentic national identity?
  • Should the government protect religious liberty equally, or give Christianity legal, financial, educational, or ceremonial preference?
  • When Christian traditions disagree, who decides which doctrines or moral rules the state will recognize?
  • Can citizens reject Christianity without being treated as less loyal, less moral, or less fully American?
  • Are political goals pursued through ordinary democratic persuasion, or justified as the recovery of a divinely ordained nation that opponents have no rightful authority to resist?

These questions separate several positions that public arguments often blur. A believer may want Christian arguments heard in legislatures but reject religious tests. Someone may value Christian history while opposing official preference. Another may support state promotion of Christianity but promise broad toleration. A harder nationalist position may make Christianity a condition of national belonging and treat pluralism as national decay.

Precision helps both criticism and conversation

For people who have left Christianity, the phrase can name a familiar pressure: the feeling that rejecting a creed also makes one suspect as a neighbor or citizen. That experience is worth describing. It does not justify assuming that every churchgoer, conservative voter, or person who calls America a Christian nation wants the same political order.

The label is most useful when it points to specific claims about identity and power. Does a proposal merely reflect a Christian citizen’s convictions, or does it ask the state to preserve Christian dominance? Does it protect religious exercise, or make one religion the measure of national loyalty? What happens to the person who says no?

Christian nationalism is therefore neither a precise name for all Christian politics nor an empty insult. It is a contested family of ideas centered on joining Christianity to national identity and public authority. The responsible task is to identify which version is present, state what evidence supports that judgment, and examine the institutions it would create. The consequences lie not in the label itself, but in who receives power, who remains equal, and who is told that the country is not fully theirs.
