Articles IV, V and VI of the Augsburg Confession
[IV. Concerning Justification]
Furthermore, it is taught that we cannot obtain forgiveness of sin and righteousness before God through our merit, work, or satisfactions, but that we receive forgiveness of sin and become righteous before God out of grace for Christ’s sake through faith when we believe that Christ has suffered for us and that for his sake our sin is forgiven and righteousness and eternal life are given to us. For God will regard and reckon this faith as righteousness in his sight, as St. Paul says in Romans 3[:21–26*] and 4[:5*].
[V. Concerning the Office of Preaching]
To obtain such faith God instituted the office of preaching, giving the gospel and the sacraments. Through these, as through means, he gives the Holy Spirit who produces faith, where and when he wills, in those who hear the gospel. It teaches that we have a gracious God, not through our merit but through Christ’s merit, when we so believe.
Condemned are the Anabaptists and others who teach that we obtain the Holy Spirit without the external word of the gospel through our own preparation, thoughts, and works.
[VI. Concerning the New Obedience]
It is also taught that such faith should yield good fruit and good works and that a person must do such good works as God has commanded for God’s sake but not place trust in them as if thereby to earn grace before God. For we receive forgiveness of sin and righteousness through faith in Christ, as Christ himself says [Luke 17:10*]: “When you have done all [things] . . . , say, ‘We are worthless slaves.’ ” The Fathers also teach the same thing. For Ambrose says: “It is determined by God that whoever believes in Christ shall be saved and have forgiveness of sins, not through works but through faith alone, without merit.”
