It is often assumed, with varying levels of confidence (depending on who is making the assertion), that the United States was founded as a Christian nation and only in recent decades has drifted away from its religious founding and roots. Repeated often enough and this assumption hardens into dogma or a default setting that some would call "common sense." Yet when we set aside inherited beliefs, perceived truths and the sense of certainty that seems requisite for any tribal mindset, we can begin to look at the founding-era record with more objectivity and sincerity. And if we have the courage to continue this pursuit, a different picture of America's Christian legacy comes into focus. The United States was not established as a Christian nation that later lost its way; it was created as a religiously plural republic whose later generations gradually constructed a specifically Christian (and overwhelmingly Protestant) national identity.
Religion permeated early American life. Churches, sermons, and biblical references were omnipresent. But the mere presence of religion in culture does not determine the character of the state. The relevant question is not whether the founders spoke religiously (of course they did...and did it A LOT), but whether they designed a government that was religiously Christian at its core.
Of course, one could easily point to evidence like Article VI of our Constitution that explicitly prohibits religious tests for office, but as Christian Nationalists will (correctly) point out, this does not prove much of anything. After all, a formal removal of "religious tests" does not equate to religious neutrality in law, culture or moral assumptions. And as our Late co-blogger, Brian Tubbs liked to point out, these protections could be seen as safeguards meant to protect religious institutions from government intrusion, not the other way around.
Yet the "religious tests" and the carefully worded prose of our nation's founding documents still reveal an important truth. At a time when European nations routinely grounded political authority in Christian identity, the framers produced a national charter that contains no appeal to God, no invocation of Christ, and no declaration of Christianity as a foundation of law. This omission was neither accidental nor uncontested. During ratification debates, objections were raised that the Constitution failed to acknowledge Christianity. Yet no corrective language was ever added.
It is almost as if this was intentional. =)
James Madison’s writings explain why. In his Memorial and Remonstrance Against Religious Assessments (1785), which opposed state support for religion in Virginia, Madison argued that religion could be directed only by “reason and conviction, not by force or violence.” Government involvement, he warned, violated conscience and corrupted faith. Years later, reflecting on church–state entanglements in his Detached Memoranda, Madison concluded that religious establishments had been “seen to result in pride and indolence in the Clergy; ignorance and servility in the laity.”
This concern was not unique to Madison. John Adams, whose own religious views would certainly be seen as unorthodox by today's evangelical standards, grasped the institutional meaning of the American experiment. In his Defence of the Constitutions of Government of the United States (1787) Adams wrote, "[T]he strength of a republic depends on religion and morality...these are cultivated voluntarily, not by law." And even in his famous Treaty of Tripoli, which Christian Nationalists dismiss as a pragmatic compromise at best, or an olive branch to the Muslim world at worst, there is little ambiguity in the words Adams chose to employ: "the government of the United States of America is not, in any sense, founded on the Christian Religion.” Regardless of personal persuasion, the fact remains that it is exceedingly difficult to argue that this sentence somehow misrepresents the founding assumptions about government and religion.
What is striking is that many Christians of this era were deeply uneasy with this arrangement. Ministers complained that the Constitution failed to acknowledge God. Others feared that liberty of conscience would undermine public morality. Their protests are revealing. They suggest that the absence of Christian nationalism was noticed, and contested, by contemporaries, rather than silently assumed as the nation’s foundation.
It is only in later generations that explicitly Christian nationalist language grows more confident. In the decades following the Civil War, American nationalism underwent a transformation. Trauma, reunification, and rapid social change encouraged the fusion of Protestant identity with national purpose. Movements emerged to amend the Constitution to recognize Christianity explicitly -- an effort that would have made little sense if such recognition already existed in any of our founding documents.
By the twentieth century, Christian nationalism became even more firmly embedded, particularly during the Cold War. In response to atheistic communism, religious language was mobilized as a marker of national identity. “Under God” was added to the Pledge of Allegiance in 1954. “In God We Trust” was elevated to official national motto in 1956. These changes were openly acknowledged as modern responses to contemporary threats, yet they were often framed as restorations of original principles.
Over time, this layered memory blurred chronology. The Founders’ religious language was lifted from its context and repurposed. Personal expressions of faith were mistaken for constitutional commitments. The result was a narrative in which Christian nationalism appeared ancient when it was, in fact, largely modern.
What the founding generation created was neither a secular vacuum nor a Christian state. It was something more restrained and, for its time, more radical. In George Washington’s 1790 letter to the Hebrew Congregation in Newport, he offered a vision of that order, promising that the government “gives to bigotry no sanction, to persecution no assistance.” Religious belief was protected precisely because the state claimed no authority to define it.
Christian nationalism, then, is not a suppressed founding inheritance waiting to be reclaimed. It is a later construction -- shaped by war, fear, and cultural conflict -- that draws selectively on the past for legitimacy. Recognizing this does not diminish religion’s role in American history. It clarifies it. And it reminds us that the founders’ most enduring insight may have been their refusal to entrust the power of the state with the fate of the soul.
