Justification by Faith Alone: Article IV of the Augsburg Confession

Ordained Minister, M.Div.

If the Augsburg Confession has a heart, it is Article IV. In a document of 28 articles spanning dozens of pages, this single article — just a few sentences long — carries the entire weight of the Reformation. Luther called justification the article on which the church stands or falls. Understanding it is understanding what the Lutheran Reformation was actually about.
What Article IV Actually Says
The article reads: 'Men cannot be justified before God by their own strength, merits, or works, but are freely justified for Christ's sake, through faith, when they believe that they are received into favor, and that their sins are forgiven for Christ's sake, who, by His death, has made satisfaction for our sins. This faith God imputes for righteousness in His sight.'
What It Means
Three key claims are packed into those sentences. First, justification is not achieved — it is received. No human effort, merit, or work contributes to standing righteous before God. Second, justification comes 'for Christ's sake' — the ground of forgiveness is what Christ has done, not what we do. Third, the means of receiving this justification is faith — trusting that we are received into God's favor through Christ.
Why Rome Objected
The Catholic Confutation rejected Article IV, arguing that faith must be formed by love (fides caritate formata) to be justifying — faith alone is insufficient. The Council of Trent later formally condemned the Lutheran position. The debate was not about whether works matter (both sides agreed they do) but about the basis of acceptance before God: Is it Christ's righteousness credited to us, or a combination of Christ's grace and our transformed nature?
Faith and Works
The Augsburg Confession is careful not to separate faith from its fruits. Article VI teaches that good works are genuinely necessary — not to earn grace but because they are God's will and flow naturally from living faith. The Lutheran position is sometimes caricatured as antinomian — as if justification by faith means works don't matter. Article VI explicitly rejects this.
Why It Still Matters
Nearly 500 years later, Article IV still addresses the deepest question of the human heart: How can I stand before a holy God? The Augsburg Confession's answer is the same as Paul's in Romans 3 and 4: by faith in Jesus Christ, who has made satisfaction for our sins. That answer has brought peace to countless troubled consciences — and continues to do so today. For the definitive commentary and study guide to the Augsburg Confession and its articles, the Kolb-Wengert volume remains the scholarly standard.
