The Three Folds (Uses) of the Law
As taught in the Lutheran tradition
Distinguishing the Law's functions as a curb (civil), a mirror (theological), and a guide (didactic).
In the Lutheran tradition, the proper distinction between the Law and the Gospel is not merely a homiletical technique or a systematic category; it is the "chief article" (Articulus stantis et cadentis ecclesiae) upon which the church stands or falls. To understand the three folds or uses of the Law (triplex usus legis), one must first grasp the Lutheran conviction that the Word of God comes to us in two distinct modes of address. The Law tells us what we are to do and leave undone, threatening punishment for disobedience and promising life for perfect adherence. The Gospel, by contrast, tells us what God has done for us in the person and work of Jesus Christ, offering the free forgiveness of sins for the sake of His merits alone.
