What is the Law/Gospel distinction?
The Law/Gospel distinction is one of the most basic categories of Reformation theology. The Law tells us what God demands; the Gospel announces what God has done. Confusing these two — or collapsing one into the other — leads to the kind of moralism that Paul opposes throughout Galatians.
Luther captured the principle memorably: "The Law commands what we cannot do; the Gospel gives us what God commands." It is in this distinction that the radical grace of justification by faith alone makes sense.
So What? Why This Matters for You
When Christians fail to distinguish between Law and Gospel, the result is anxious religion. Either we treat the Gospel as a softer Law (turning grace into a new performance treadmill) or we treat the Law as the Gospel (declaring ourselves righteous because we tried hard enough).
Recovering this distinction means recovering the freedom of the Christian: we are simultaneously sinful and righteous, condemned by the Law and embraced by the Gospel, kept from despair by the announcement that Christ has done it all.
What The Confessions Say
The Law shows us our sin; the Gospel shows us our Savior. These are the two essential parts of the Word of God, and they must not be confused.
