The Augsburg Confession (Confessio Augustana, 1530)

Also they teach that 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. Rom. 3 and 4. Article V: Of the Ministry. That we may obtain this faith, the Ministry of Teaching the Gospel and administering the Sacraments was instituted. For through the Word and Sacraments, as through instruments, the Holy Ghost is given, who works faith; where and when it pleases God, in them that hear the Gospel, to wit, that God, not for our own merits, but for Christ's sake, justifies those who believe that they are received into grace for Christ's sake. They condemn the Anabaptists and others who think that the Holy Ghost comes to men without the external Word, through their own preparations and works. Article VI: Of New Obedience. Also they teach that this faith is bound to bring forth good fruits, and that it is necessary to do good works commanded by God, because of God's will, but that we should not rely on those works to merit justification before God. For remission of sins and justification is apprehended by faith, as also the voice of Christ attests: When ye shall have done all these things, say: We are unprofitable servants. Luke 17, 10. The same is also taught by the Fathers. For Ambrose says: It is ordained of God that he who believes in Christ is saved, freely receiving remission of sins, without works, by faith alone. Article VII: Of the Church. Also they teach that one holy Church is to continue forever. The Church is the congregation of saints, in which the Gospel is rightly taught and the Sacraments are rightly administered.…
