Core passage idea

Paraphrase · Public domain

Temporal rulers are ordained by God to restrain evil with the sword, but their authority cannot reach the conscience or command true faith.

It marks a boundary the state may not cross, protecting inner faith from coercion while affirming civil obedience.

To avoid a bubble

Pair with John Locke, A Letter Concerning Toleration.

Reading note

Read it within Reformation debates over church and state, noting both its obedience and its limits on rulers.

Best paired with

John Locke, A Letter Concerning Toleration
