TETRACHORDON

A Modernised Tetrachordon by John Milton - with Commentary by S. C. Sayles

John Milton's Tetrachordon (1645) stands as one of the boldest and most rigorous biblical examinations of marriage and divorce ever written in the English language. Composed during the upheavals of seventeenth-century England, amid civil war, ecclesiastical collapse, and fierce debates over Scripture and authority, it confronts questions that remain unresolved to this day: What is marriage in substance? When does it fail in truth rather than merely in form? And how must Christ's teaching be read in continuity with the Law rather than against it?

This modernised edition presents Tetrachordon in full, with spelling and punctuation carefully updated for clarity while preserving Milton's argument, structure, and theological force. Unlike abridged or selectively quoted versions, the text is given complete, allowing readers to encounter Milton's reasoning directly and without distortion. The original address to Parliament is retained, situating the work firmly within its historical moment and revealing the public courage with which Milton defended his position against clerical censure.

Milton's method is distinctive and demanding. Rather than isolating proof texts, he brings four key passages of Scripture into deliberate harmony-Genesis 2, Deuteronomy 24, Matthew 19, and 1 Corinthians 7-arguing that they sound together like the four strings of a single instrument. His central claim is not libertine but moral: that marriage exists for peace, fidelity, mutual help, and the flourishing of the soul, and that when these ends are irrevocably destroyed, Scripture provides remedy rather than commanding the perpetuation of a hollow form. Divorce, for Milton, is not an indulgence of desire but a tragic concession to moral reality.

Accompanying the modernised text is a substantial analytical commentary by S. C. Sayles, guiding the reader through Milton's arguments with historical, theological, and exegetical clarity. The commentary situates Tetrachordon within its seventeenth-century context-engaging the Westminster Assembly, Milton's related divorce tracts, and the wider Reformation debate-while also drawing out its enduring relevance for contemporary discussions of marriage, conscience, and ecclesial authority. Sayles neither sanitises Milton nor treats him as infallible; instead, he reads him seriously, testing his claims against Scripture, history, and moral coherence.

This volume will challenge readers across the theological spectrum. Some will find Milton unsettling; others will find him bracingly honest. But none can dismiss him as shallow or careless. Tetrachordon demonstrates that Protestant thought on marriage and divorce has never been monolithic, and that appeals to "historic Christian teaching" often conceal a far richer and more contested tradition.

This book is for readers who value Scripture over slogans, moral reality over inherited formulae, and careful reasoning over easy answers. It is essential reading for pastors, theologians, historians, and serious lay readers seeking to understand how deeply-and how long-the Church has wrestled with the meaning of marriage.

John Milton's Tetrachordon, modernised and fully presented, with commentary by S. C. Sayles, invites the reader not to comfort, but to truth.
