Faith and Freedom: Deism vs. Christianity in the American Founding

Every few years, someone publishes a book arguing that America was founded as a Christian nation. A few months later, someone publishes a book arguing the opposite. Both books have receipts. Both books are missing something.

The truth about faith and the American founding is not a simple either/or. It's a story about men who lived inside a Christian moral universe, held widely divergent theological views, built institutions deliberately agnostic on sectarian questions, and produced a founding philosophy that drew from Christian sources without being strictly Christian in any denominational sense.

Understanding this matters -- not just for history class, but for understanding what America actually is and what faith's role in it actually has been.

The Deism Question

Deism, as it was understood in the 18th century, held that God created the universe, set it in motion according to rational laws, and generally did not intervene in daily affairs. Deists believed in God. They believed in morality, often derived from religious sources. They rejected miracles, institutional religion, and doctrinal claims that couldn't be verified by reason.

Several of the major founders held views that can be described as broadly Deist. Jefferson famously produced a version of the Gospels with the supernatural elements removed, keeping what he called "the most sublime and benevolent code of morals which has ever been offered to man." Franklin, at the Constitutional Convention, proposed daily prayer but admitted in his autobiography to "some doubts" about the divinity of Jesus.

But Deism in the 18th century was not atheism or even secularism in any modern sense. Deists believed in Providence -- the idea that God was active in history, guiding events toward purposes humans might not always perceive. Washington's correspondence is saturated with references to Providence. The Declaration of Independence appeals four times to the divine: the Creator, the Supreme Judge, Providence, and the laws of Nature and Nature's God.

The Range of Belief

The founders were not a theological monolith. This needs to be said clearly, because both sides of the modern debate tend to flatten them.

John Adams was raised Calvinist, moved toward Unitarianism, read widely in world religions, and held what he called an "illuminated faith" that rejected orthodox Christianity while maintaining deep reverence for biblical morality. He wrote that the Constitution was designed only for "a moral and religious people" -- a statement with profound implications for how he understood the relationship between faith and republican government.

Patrick Henry was a committed Anglican who taught himself scripture and argued publicly that Christianity was essential to American liberty. He wrote: "It cannot be emphasized too strongly or too often that this great nation was founded, not by religionists, but by Christians; not on religions, but on the Gospel of Jesus Christ."

Benjamin Rush, one of the signers least remembered and most interesting, was a devout Presbyterian who believed the Bible should be a central text in American education. He wrote: "In contemplating the political institutions of the United States, if we were to remove the Bible from schools, I lament that we could be wasting so much time and money in punishing crimes and taking so little pains to prevent them."

The First Amendment's Purpose

The First Amendment's religion clauses -- "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof" -- are sometimes read as evidence that the founders intended a secular republic. This misreads the history.

The establishment clause was not designed to protect the republic from religion. It was designed to protect religion from the republic -- and specifically to prevent the federal government from doing what European states had done for centuries, which was picking a winner among competing Christian denominations and using state power to enforce it.

Virginia Baptists, who had been jailed for preaching without a license under the Anglican establishment in colonial Virginia, were among the strongest advocates for disestablishment. Their argument was not that religion should be excluded from public life. It was that government interference in religion corrupted both. Roger Williams, a century earlier, had called institutional church-state fusion "a soul rape."

The separation of church and state, as the founders understood it, was a protection for religious liberty -- not a declaration of secular government.

What the Founding Documents Actually Say

The Constitution, notably, does not mention God, Christianity, or the Bible. This was not an accident. The founders were creating a national government that needed to accommodate citizens of many denominations -- and they knew that any specific theological language would immediately create battles they didn't need.

The Declaration of Independence is different. It makes four appeals to the divine. The "Creator" who endows humans with rights is a theistic concept -- rights come from God, not from government. The "Supreme Judge of the world" to whom the founders appealed in the declaration's final paragraph is explicitly theological. These were not empty rhetorical flourishes. They were claims with substantive implications: human dignity is grounded in something prior to human law.

The national motto "In God We Trust" was officially adopted in 1956, but the phrase appeared on American coins as early as 1864. "One nation under God" was added to the Pledge in 1954. These mid-20th-century additions were deliberate choices to distinguish American identity from Soviet atheism -- but they built on a foundation that was already there.

The Practical Consequence

The founders built a republic that could not sustain itself without the moral character they believed only religion could cultivate. They disagreed about which religion, and they deliberately declined to name one. But they were nearly unanimous that self-government required self-restraint, and that self-restraint required something like what Christianity taught.

Washington's Farewell Address put it plainly: "Of all the dispositions and habits which lead to political prosperity, religion and morality are indispensable supports." He did not say which religion. But he was not being evasive. He was describing a political philosophy -- that republican government depends on citizens who can govern themselves, and that self-government of that kind requires moral formation that secular philosophy alone had not proven adequate to produce.

Whether that argument holds in 2026 is a question Americans are still working out. What's clear is that the founders' view of faith and freedom was not simple, and it was not secular in any modern sense of that word. They built a country that took God seriously, even when they disagreed about which God and how.
