Locke’s case for separating the church from the power of the state - that belief cannot be coerced, so persecution is both wrong and futile.
To understand Locke’s plea for toleration, you must feel the world it answered. Europe had spent more than a century tearing itself apart over religion - the Wars of Religion in France, the Thirty Years’ War that killed a huge fraction of central Europe, the English Civil War, persecutions, inquisitions, expulsions, and executions, all turning on which form of Christianity the state would enforce. The reigning assumption was that a stable society required one religion, upheld by the power of the state, and that dissent and heresy were threats to be suppressed by force. Against this blood-soaked background, Locke wrote his Letter Concerning Toleration (1689), arguing for something then radical: that the state should not enforce religious belief at all, and that people of different faiths could and should be allowed to live together in peace.
Locke’s solution rests on a sharp distinction between two kinds of human association with two entirely different ends. The commonwealth (the state) exists to secure people’s civil interests - life, liberty, health, and possessions - and the magistrate’s power consists in outward force: laws, penalties, the sword. The church, by contrast, is a voluntary society of people who join together to worship God in the way they believe acceptable to him, and its end is the salvation of souls, which can be pursued only by inward conviction, persuasion, and example - never by force. These two societies have different purposes, different members, and different means, and they should not be confused or merged. The magistrate has no authority over souls, because his only tool is force and force cannot reach the soul; the church has no authority to wield the sword, because compulsion has no place in the care of souls. Keep the two strictly separate, Locke argues, and the wars of religion lose their cause: the state stops trying to save souls, the churches stop trying to seize the state, and people of different faiths can live together as fellow citizens.
What Locke is constructing, step by step, is the foundation of one of the modern world’s most important institutions: the separation of church and state. If the state’s authority is confined to civil interests and outward force, and religion belongs to the inward realm of conscience that force cannot reach, then the state has no business establishing an official religion, compelling worship, punishing heresy, or favouring one faith over another. Religion becomes a private matter of voluntary association and individual conscience, fenced off from the coercive power of government. The state guarantees the peace within which different faiths coexist, but takes no side among them.
This was a genuinely new vision of how a society could be organised, and its consequences were vast. It pointed toward the disestablishment of state churches, toward freedom of religious worship as a civil right, and toward the broader principle that there are regions of human life - conscience, belief, private conviction - into which the state simply may not intrude. The American founders, a century later, would write this into the First Amendment’s guarantee that government shall make no law establishing a religion or prohibiting its free exercise; Jefferson would call it a ‘wall of separation between church and state.’ Locke did not build the whole wall, and his own version of toleration was incomplete and exclusionary. But he laid its foundation stone: the argument that the coercive power of the state and the inward realm of religious conviction belong to two different worlds that should be kept apart.
This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.
You learned that Locke argued for separating church from state because belief cannot be coerced. State that argument, and name one group he refused to tolerate and why.
Leads to Benedict de Spinoza.
