A Wall of Separation: Religious Freedom

Jefferson counted his Virginia Statute for Religious Freedom among the three achievements he wished carved on his tomb - the law that made conscience free and severed the state from the church.

From the lesson

Thomas Jefferson was President of the United States, Secretary of State, Vice President, Governor of Virginia, founder of a university, and author of the Declaration of Independence. Yet when he composed his own epitaph, he left out every office he had held, including the presidency. He asked to be remembered for exactly three things: author of the Declaration of Independence, father of the University of Virginia, and author of the Virginia Statute for Religious Freedom. That he ranked the Statute among the three proudest achievements of his life - above being President - tells us how central the cause of religious liberty was to his understanding of human freedom.

The Statute, drafted by Jefferson in 1777 and passed by the Virginia legislature in 1786 after a long fight led by Madison, did something radical for its age. It disestablished the official church, ended compulsory taxes for religion, and declared that no one could be compelled to support or attend any worship, nor suffer any civil penalty or disadvantage on account of their religious opinions. Belief, Jefferson insisted, was to be entirely free, and entirely outside the reach of the state. It was one of the first laws anywhere to guarantee complete religious liberty, and it became a model for the First Amendment’s protection of free exercise and its bar on establishment.

One of Jefferson’s most striking arguments for religious liberty anticipates the liberal ‘harm principle’ that John Stuart Mill would later make famous: government may rightfully restrain only those actions that injure others, and a person’s religious beliefs, however erroneous, injure no one but possibly themselves. ‘The legitimate powers of government extend to such acts only as are injurious to others,’ Jefferson wrote in his Notes on the State of Virginia; ‘but it does me no injury for my neighbour to say there are twenty gods, or no god. It neither picks my pocket nor breaks my leg.’ What another believes about God costs me nothing and is therefore none of the state’s concern.

This argument cuts the ground out from under every justification for religious persecution. The persecutor claims to be protecting society, or the persecuted person’s own soul, or God’s honour. Jefferson answers that society suffers no injury from another’s belief; that a person’s soul is their own affair; and that God needs no protection from the state. Far from harming the commonwealth, he argued, the free competition of religious opinions is positively healthy - truth is great and will prevail if left to itself, and has nothing to fear from error so long as reason is free to combat it. Persecution, by contrast, has filled history with blood and produced only hypocrisy, never genuine faith. The state’s entanglement with religion corrupts both: it makes religion the servant of power and makes the state the enforcer of dogma. Better, Jefferson concluded, to leave belief entirely free and let religion stand on its own merits in the open marketplace of conscience.

In 1802, as President, Jefferson replied to a letter from the Danbury Baptist Association in Connecticut, a religious minority that had suffered under that state’s established church and feared for their liberty. In his reply Jefferson coined a metaphor that would shape American constitutional law for two centuries. The First Amendment, he wrote, in declaring that Congress shall make no law respecting an establishment of religion or prohibiting its free exercise, had built ‘a wall of separation between Church and State.’ Religion, he assured the Baptists, was a matter solely between each person and their God; government had no business in it; and the people’s rights of conscience were secured by keeping the two domains entirely apart.

The phrase ‘wall of separation’ was not in the Constitution itself, but it captured Jefferson’s understanding of what the religion clauses meant, and the Supreme Court would later adopt it as a guiding interpretation. The image is powerful and consequential: a wall is not a one-way barrier but a mutual separation, protecting the state from the church’s sectarian demands and the church from the state’s corrupting embrace. For Jefferson and Madison, this separation was the great safeguard of both religious liberty and civil peace. A government that could establish one religion could persecute the others; a religion entangled with the state would be corrupted by power and would corrupt the state in turn. Only a wall between them could keep conscience free, religion vital, and the republic at peace among its many faiths - and the metaphor he tossed off in a private letter became one of the foundational ideas of the American settlement.

This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.

What you'll be able to recall

You learned that Jefferson held religious belief to be entirely outside the authority of government. In your own words, why did he think compelling belief was both tyrannical and futile?
