This is why, for Luther, the phrase “the third use of the Law” (i.e. a use of the Law after the gospel and thus unique to Christians) is a category mistake. For him, as suggested above, Law names the divine speech that accuses and kills. Cut off from its conditionality and kicked out of the Christian’s conscience, a commandment is not Law in the theological sense. This does not mean that Luther didn’t think those portions of scripture that we think of as Law should be preached to Christians; he emphatically did (as his disputations against the Antinomians and his expositions of the Ten Commandments in the Catechisms demonstrate). But it does mean that “Law” is a slightly misleading term in this context because Law, for Luther, is defined by its “chief and proper use” which is “to reveal sin” and function as a “Hercules to attack and subdue the monster” of self-righteousness (Galatians 1535).
