Theoretical-Practical Theology, vol. 1: Prolegomena

As to the books you speak of: Mastricht is sometimes in one volume, a very large thick quarto, sometimes in two quarto volumes. I believe it could not be had new under 8 or 10 pounds. Turretin is in three volumes in quarto, and would probably be about the same price. They are both excellent. Turretin is on polemical divinity, on the 5 points & all other controversial points, & is much larger in these than Mastricht, & is better for one that desires only to be thoroughly versed in controversies. But take Mastricht for divinity in general, doctrine, practice & controversy, or as an universal system of divinity; & it is much better than Turretin or any other book in the world, excepting the Bible, in my opinion.

—Jonathan Edwards to Joseph Bellamy, January 15, 1747 (in The Works of Jonathan Edwards, vol. 16: Letters and Personal Writings)

With each translation of the formative Reformed theologians of the sixteenth and seventeenth centuries comes the possibility of our churches being renewed by forgotten treasures. This is one of those gold mines. So important is van Mastricht that even Descartes felt obliged to respond to his critiques and Jonathan Edwards drew deeply from the well of his Theoretical-Practical Theology. It is a distinct pleasure to recommend this remarkable gem.

—Michael Horton, J. Gresham Machen Professor of Systematic Theology and Apologetics, Westminster Seminary California

Van Mastricht is one of the greatest of the Reformed orthodox, exerting a profound influence on subsequent theologians, including Jonathan Edwards. His grasp of the tradition, his ability to interact with contemporary issues, and his careful articulation of orthodoxy exemplify the best of Protestant theology after the Reformation. Yet the lack of an English translation has meant that he has been known more by reputation than by content in the Anglophone world. Here at last is an English translation which will allow a whole new audience of pastors, theologians, and laypeople to draw once again on this profound theological source.

—Carl R. Trueman, professor of biblical and religious studies, Grove City College

A new appreciation has grown in our time for the great post-Reformation theologians of the Reformed tradition, and Petrus van Mastricht was a towering giant among them. Jonathan Edwards thought he was better than Francis Turretin! Mastricht’s magnum opus Theoretical-Practical Theology, however, is virtually unknown and unquoted today, accessible only to competent and determined Latinists. This translation does for Mastricht what Giger and Dennison did for Turretin—it provides a readable, critical, annotated English translation that puts Mastricht within easy reach of pastors, seminarians, and other students of theology. A sound and experiential divine, who (it may surprise you to learn) interacts with and criticizes Kabbalah and Islam as well as Descartes and Socinians, Mastricht is always concerned to show that true theology is practical and never merely notional. Truth is unto godliness.

—Ligon Duncan, chancellor and CEO, John E. Richards Professor of Systematic and Historical Theology, Reformed Theological Seminary

Any serious student of Reformed theology needs to sit at the feet of Petrus van Mastricht. The challenge has been that to do so you needed to know Latin or Dutch. Thanks to the herculean efforts of the folks at the Dutch Reformed Translation Society and Reformation Heritage Books, English readers can now learn the art of ‘living for God through Christ.
