Martin Luther argued that the Hebrew Bible's Song of Songs was “an encomium of the political order,” a praise and thanksgiving to God for the gift of temporal government. Luther's political interpretation of this book was unique in his age, and remains so in the history of biblical commentary. This paper offers an account of Luther's peculiar interpretation, as well as its place in his interpretation of the Bible and in the history of biblical commentary, by arguing that it exhibits the foundational idea of his political thought that secular authority is a precious gift from God, and that the Song of Songs, as a praise of conjugal love, provides for political authority a fitting biblical encomium.
