“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 and 4.
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 Anabaptist and others who teach that we obtain the Holy Spirit without the external word of the gospel through our own preparation, thoughts, and works”
– The Augsburg Confession, Articles 4-5
