The Scriptures cited by the adversaries do not speak of canonical satisfactions. It is pure slander when they distort Scripture to their own opinions. We say that good fruit, good works in every kind of life, should follow repentance, that is, conversion or regeneration. Neither can there be true conversion or true contrition where the putting to death of the flesh and bearing good fruit do not follow. True terrors, true griefs of mind, do not allow the body to satisfy itself in sensual pleasures, and true faith is not ungrateful to God. Neither does true faith hate God's commandments. In a word, there is no inner repentance unless it also produces the outward putting to death of the flesh. We say that this is John's meaning when he says, "Bear fruit in keeping with repentance" (Matt. 3:8). Likewise of Paul when he says, "Present your members as slaves to righteousness" (Rom. 6:19); just as he likewise says elsewhere, "Present your bodies as a living sacrifice" (Rom. 12:1), and so forth. When Christ says, "Repent" (Matt. 4:17), He certainly speaks of repentance in its entirety, newness of life and its fruit.
These Scripture passages have nothing to do with scholastic satisfactions. They imagine that satisfactions are works that are not due. However, Scripture requires works that are due. For this word of Christ, "Repent," is the word of a commandment. (paragraphs 34-36)
