The Nature and Definition of the Law
As taught in the Lutheran tradition
Defining the Law as God's unchanging will that commands, forbids, and condemns the sinner.
In the Lutheran tradition, the question of what constitutes the "Law of God" is not merely a matter of ethics or social ordering; it is a fundamental ontological and theological inquiry that determines the very possibility of the Gospel. At its core, the subtopic of the nature and definition of the Law answers the question: What is God’s immutable will for humanity, and how does He communicate His holy character to a fallen world? For the Lutheran, the Law is not a transient set of rules that evolves with culture, nor is it a secondary "plan B" after the failure of Eden. It is the eternal, unchanging expression of God’s holiness. To understand the Law is to understand the "Alien Work" of God (the Opus Alienum), through which He crushes the pride of the sinner to make room for His "Proper Work" (Opus Proprium), which is the proclamation of the Gospel.
