Reformed natural law

Just out: David van Drunen’s new book, Natural Law and the Two Kingdoms: A Study in the Development of Reformed Social Thought. From the publisher’s summary:

Conventional scholarship holds that the theology and social ethics of the Reformed tradition stand at odds with concepts of natural law and the two kingdoms. But David VanDrunen here challenges that status quo through his careful, thoroughgoing exploration of the development of Reformed social thought from the Reformation to the present.

John Frame reviews van Drunen and plays the Reformed sola Scriptura trump card:

To repeat, I am convinced that there is such a thing as natural law. But I am not at all convinced of Van Drunen’s (or anyone else’s) distinction between religious and secular kingdoms, and I do not see any reason to limit the use of Scripture to the religious kingdom as Van Drunen suggests. Scripture is God’s word, and God’s word is the foundation of morality. When we want to draw people, believers or unbelievers, to that foundation, we should be unashamed to refer to Scripture. I grant that there are many cultural forces telling us not to refer to Scripture in the public square. But we should not listen to them. The attempt of Van Drunen and others to convince us not to apply Scripture to civil matters is a failure.
