Justification by Faith

Augsburg Confession

"Also they teach that the Word, that is, the Son of God, did assume the human nature in the womb of the blessed Virgin Mary, so that there are two natures, the divine and the human, inseparably conjoined in one Person, one Christ, true God and true man, who was born of the Virgin Mary, truly suffered, was crucified, dead, and buried, that He might reconcile the Father unto us, and be a sacrifice, not only for original guilt, but also for all actual sins of men."
Augsburg Confession, III. #1. Of the Son of God. Concordia Triglotta, St. Louis: Concordia Publishing House, 1921, p. 45. Tappert, p. 29.

“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. Romans 3 and 4.”

Apology of the Augsburg Confession

"The Third Article the adversaries approve, in which we confess that there are in Christ two natures, namely, a human nature, assumed by the Word into the unity of His person; and that the same Christ suffered and died to reconcile the Father to us; and that He was raised again to reign, and to justify and sanctify believers, etc., according to the Apostles' Creed and the Nicene Creed."

"Faith is that my whole heart takes to itself this treasure. It is not my doing, not my presenting or giving, not my work or preparation, but that a heart comforts itself, and is perfectly confident with respect to this, namely, that God makes a present and gift to us, and not we to Him, that He sheds upon us every treasure of grace in Christ."
Apology of the Augsburg Confession, IV. #48. Of Justification. Concordia Triglotta, St. Louis: Concordia Publishing House, 1921, p. 135.

"Now, that faith signifies, not only a knowledge of the history, but such faith as assents to the promise, Paul plainly testifies when he says, Romans 4:16: 'Therefore it is of faith, to the end the promise might be sure.' For he judges that the promise cannot be received unless by faith. Wherefore he puts them together as things that belong to one another, and connects promise and faith."
Apology of the Augsburg Confession, Article IV. #51. Of Justification, Concordia Triglotta, St. Louis: Concordia Publishing House, 1921, p. 135. Romans 4:16. Tappert, p. 114.

"This faith, encouraging and consoling in these fears, receives remission of sins, justifies and quickens. For this consolation is a new and spiritual life [a new birth and a new life]. These things are plain and clear, and can be understood by the pious, and have testimonies of the Church [as is to be seen in the conversion of Paul and Augustine]. The adversaries nowhere can say how the Holy Ghost is given. They imagine that the Sacraments confer the Holy Ghost ex opere operato, without a good emotion in the recipient, as though, indeed, the gift of the Holy Ghost were an idle matter."

"Now we will show that faith [and nothing else] justifies."
Apology of the Augsburg Confession, IV. #69. Of Justification. Concordia Triglotta, St. Louis: Concordia Publishing House, 1921, p. 141. Tappert, p. 116.

"But to believe is to trust in the merits of Christ, that for His sake God certainly wishes to be reconciled with us. Likewise, just as we ought to maintain that, apart from the Law, the promise of Christ is necessary, so also is it needful to maintain that faith justifies. [For the Law does not preach the forgiveness of sin by grace.] For the Law cannot be performed unless the Holy Ghost be first received. It is, therefore, needful to maintain that the promise of Christ is necessary. But this cannot be received except by faith. Therefore, those who deny that faith justifies, teach nothing but the Law, both Christ and the Gospel being set aside.”
Apology of the Augsburg Confession, IV. #69. Of Justification. Concordia Triglotta, St. Louis: Concordia Publishing House, 1921, p. p. 141. Tappert, p. 116.

"We do not believe thus {that faith is just a beginning of justification} concerning faith, but we maintain this, that properly and truly, by faith itself, we are for Christ's sake accounted righteous, or are acceptable to God. And because 'to be justified' means that out of unjust men just men are made, or born again, it means also that they are pronounced or accounted just. For Scripture speaks in both ways. [The term to be justified is used in two ways: to denote, being converted or regenerated; again, being accounted righteous.] Accordingly we wish first to show this, that faith alone makes of an unjust, a just man, i. e., receives remission of sins."
Apology of the Augsburg Confession, IV. #71-2. Of Justification. Concordia Triglotta. St. Louis: Concordia Publishing House, 1921, p. 141. Tappert, p. 116f.

"But since we receive remission of sins and the Holy Ghost by faith alone, faith alone justifies, because those reconciled are accounted righteous and children of God, not on account of their own purity, but through mercy for Christ's sake, provided only they by faith apprehend this mercy."
Apology of the Augsburg Confession, IV. #86. Of Justification. Concordia Triglotta, St. Louis: Concordia Publishing House, 1921, p. 147. Tappert, p. 119.

"In the Epistle to the Romans, Paul discusses this topic especially, and declares that, when we believe that God, for Christ's sake, is reconciled to us, we are justified freely by faith."

"These things are so plain and so manifest that we wonder that the madness of the adversaries is so great as to call them into doubt. The proof is manifest that, since we are justified before God not from the Law, but from the promise, it is necessary to ascribe justification to faith."
Apology of the Augsburg Confession, III. #177. Of Love and the Fulfilling of the Law. Concordia Triglotta, St. Louis: Concordia Publishing House, 1921, p. 205. Tappert, p. 153.

"Scripture thus uses the term faith, as the following sentence of Paul testifies, Romans 5:1: Being justified by faith, we have peace with God. Moreover, in this passage, to justify signifies, according to forensic usage, to acquit a guilty one and declare him righteous, but on account of the righteousness of another, namely, of Christ, which righteousness of another is communicated to us by faith...1 Corinthians 1:30. Of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption. And 2 Corinthians 5:21 For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him. But because the righteousness of Christ is given us by faith, faith is for this reason righteousness in us imputatively, i. e., it is that by which we are made acceptable to God on account of the imputation and ordinance of God, as Paul says, Romans 4:3, 5: Faith is reckoned for righteousness."

"But as the Confutation condemns us for having assigned these two parts to repentance, we must show that [not we, but] Scripture expresses these as the chief parts in repentance and conversion. For Christ says, Matthew 11:28: Come unto Me, all ye that labor and are heavy laden, and I will give you rest. Here there are two members. The labor and the burden signify the contrition, anxiety, and terrors of sin and of death. To come to Christ is to believe that sins are remitted for Christ's sake; when we believe, our hearts are quickened by the Holy Ghost through the Word of Christ. Here, therefore, there are these two chief parts, contrition and faith."

“That absolution, however, is not received except by faith can be proved from Paul, who teaches, Romans 4:16, that the promise cannot be received except by faith. But absolution is the promise of the remission of sins [nothing else than the Gospel, the divine promise of God’s grace and favor]. Therefore, it necessarily requires faith. Neither do we see how he who does not assent to it may be said to receive absolution.”

The Smalcald Articles

“Likewise: All have sinned and are justified without merit [freely, and without their own works or merits] by His grace, through the redemption that is in Christ Jesus, in His blood, Romans 3:23f. Now, since it is necessary to believe this, and it cannot be otherwise acquired or apprehended by any work, law, or merit, it is clear and certain that this faith alone justifies us, as St. Paul says, Romans 3:28: For we conclude that a man is justified by faith, without the deeds of the Law. Likewise, v. 26: That He might be just, and the Justifier of him which believeth in Christ.”
Smalcald Articles, The Second Part, Article I. #4. Concordia Triglotta, St. Louis: Concordia Publishing House, 1921, p. 461. Tappert, p. 292.

“What I have hitherto and constantly taught concerning this I know not how to change in the least, namely, that by faith, as St. Peter says, we acquire a new and clean heart, and God will and does account us entirely righteous and holy for the sake of Christ, our Mediator. And although sin in the flesh has not yet ben altogether removed or become dead, yet He will not punish or remember it. And such faith, renewal, and forgiveness of sins is followed by good works.”

The Large Catechism

"Therefore there is here again great need to call upon God and pray: Dear Father, forgive us our trespasses. Not as though He did not forgive sin without and even before our prayer (for He has given us the Gospel, in which is pure forgiveness before we prayed or ever thought about it). But this is to the intent that we may recognize and accept {erkennen und annehmen; agnoscamus et accipiamus} such forgiveness. For since the flesh in which we daily live is of such a nature that it neither trusts nor believes God, and is ever active in evil lusts and devices, so that we sin daily in word and deed, by commission and omission, by which the conscience is thrown into unrest, so that it is afraid of the wrath and displeasure of God, and thus loses the comfort and confidence derived from the Gospel; therefore it is ceaselessly necessary that we run hither and obtain consolation to comfort the conscience again."[1][21]

Formula of Concord

"The third controversy which has arisen among some theologians of the Augsburg Confession is concerning the righteousness of Christ or of faith, which God imputes by grace, through faith, to poor sinners for righteousness."
Formula of Concord, Thorough Declaration, III. #1. Of the Righteousness of Faith before God. Concordia Triglotta, St. Louis: Concordia Publishing House, 1921, p. 917. Tappert, p. 539.


"These treasures are offered us by the Holy Ghost in the promise of the holy Gospel; and faith alone is the only means by which we lay hold upon, accept, and apply, and appropriate them to ourselves. This faith is a gift of God, by which we truly learn to know Christ, our Redeemer, in the Word of the Gospel, and trust in Him, that for the sake of His obedience alone we have the forgiveness of sins by grace, are regarded as godly and righteous by God the Father, and are eternally saved."

"Accordingly, the word justify here means to declare righteous and free from sins, and to absolve one from eternal punishment for the sake of Christ's righteousness, which is imputed by God to faith, Philippians 3:9. For this use and understanding of this word is common in the Holy Scriptures of the Old and the New Testament. Proverbs 17:15: He that justifieth the wicked, and he that condemneth the just, even they both are abomination to the Lord. Isaiah 5:23: Woe unto them which justify the wicked for reward, and take away the righteousness of the righteous from him! Romans 8:33: Who shall lay anything to the charge of God's elect? It is God that justifieth, that is, absolves from sins and acquits."

"For when man is justified through faith [which the Holy Ghost alone works], this is truly a regeneration, because from a child of wrath he becomes a child of God, and thus is transferred from death to life, as it is written; When we were dead in sins, He hath quickened us together with Christ, Ephesians 2:5. Likewise: The just shall live by faith, Romans 1:17; Habakkuk 2:4."

“But here very good attention must be given with especial diligence, if the article of justification is to remain pure, lest that which precedes faith, and that which follows after it, be mingled together or inserted into the article of justification as necessary and belonging to it, because it is not one or the same thing to speak of conversion and of justification. For not everything that belongs to conversion belongs likewise to the article of justification, in and to which belong and are necessary only the grace of God, the merit of Christ, and faith, which receives this in the promise of the Gospel, whereby the righteousness of Christ is imputed to us, whence we receive and have forgiveness of sins, reconciliation with God, sonship, and heirship of eternal life. Therefore true, saving faith is not in those who are without contrition and sorrow, and have a wicked purpose to remain and persevere in sins; but true contrition precedes, and genuine faith is in or with true repentance [justifying faith is in those who repent truly, not feignedly].”

"Moreover, neither contrition nor love or any other virtue, but faith alone is the sole means and instrument by which and through which we can receive and accept the grace of God, the merit of Christ, and the forgiveness of sins, which are offered us in the promise of the Gospel."

"Here belongs also what St. Paul writes Romans 4:3, that Abraham was justified before God by faith alone, for the sake of the Mediator, without the cooperation of his works, not only when he was first converted from idolatry and had no good works, but also afterwards, when he had been renewed by the Holy Ghost, and adorned with many excellent good works, Genesis 15:6; Hebrews 11:8. And Paul puts the following questions, Romans 4:1ff.: On what did Abraham's righteousness before God for everlasting life, by which he had a gracious God, and was pleasing and acceptable to Him, rest at that time?"

"For good works do not precede faith, neither does sanctification precede justification. But first faith is kindled in us in conversion by the Holy Ghost from the hearing of the Gospel. This lays hold of God's grace in Christ, by which the person is justified. Then, when the person is justified, he is also renewed and sanctified by the Holy Ghost, from which renewal and sanctification the fruits of good works then follow."

“...God in His purpose and counsel ordained [decreed]:

That the human race is truly redeemed and reconciled with God through Christ, who, by His faultless [innocency] obedience, suffering, and death, has merited for us the righteousness which avails before God, and eternal life.
That such merit and benefits of Christ shall be presented, offered, and distributed to us through His Word and Sacraments.
That by His Holy Ghost, through the Word, when it is preached, heard, and pondered, He will be efficacious and active in us, convert hearts to true repentance, and preserve them in the true faith.
That He will justify all those who in true repentance receive Christ by a true faith, and will receive them into grace, the adoption of sons, and the inheritance of eternal life."

"On this account, as the Augsburg Confession in Article XI says, we also retain private absolution, and teach that it is God's command that we believe such absolution, and should regard it as sure that, when we believe the word of absolution, we are as truly reconciled to God as though we had heard a voice from heaven, as the Apology explains this article. This consolation would be entirely taken from us if we were not to infer the will of God towards us from the call which is made through the Word and through the Sacraments."

David Chytraeus, Concordist

"How is a person justified before God? This occurs solely by faith in the Son of God, Jesus Christ; that is, freely, not because of any works or merits of one's own but only because of the one Mediator, Jesus Christ, who became the sacrificial victim and propitiation on our behalf. By this sacrifice, man obtained forgiveness of sins and became righteous; that is, God-pleasing and acceptable. His righteousness was imputed to man for Christ's sake, and man becomes an heir of eternal life when he believes with certainty that God gives him these blessings for the sake of His Son."
David Chytraeus, A Summary of the Christian Faith (1568), trans., Richard Dinda, Decatur: Repristination Press, 1994. p. 105.

"Christian righteousness is the forgiveness of sin, the imputation of the righteousness of Christ and acceptance to eternal life. It is free, not the result of any virtues or works but is given solely because of Christ, the Mediator, and apprehended by faith alone."
David Chytraeus, A Summary of the Christian Faith (1568), trans., Richard Dinda, Decatur: Repristination Press, 1994. p. 106.

"Scripture therefore uses these words, 'We are justified by faith,' to teach both: 1) What the reason (or merit) for justification is, or what the blessings of Christ are; to wit, that through and for the sake of Christ alone we are granted forgiveness of sins, righteousness and eternal life; and 2. How these should be applied or transferred to us; namely, by embracing the promise and relying on Christ by faith alone."
David Chytraeus, A Summary of the Christian Faith (1568), trans., Richard Dinda, Decatur: Repristination Press, 1994. p. 107.

Martin Chemnitz, Concordist

"But when we are speaking of the subject itself, it is certain that the doctrine of gracious reconciliation, of the remission of sins, of righteousness, salvation, and eternal life through faith for the sake of the Mediator is one and the same in the Old and in the New Testament. This is a useful rule which we must retain at all costs: The doctrine, wherever we read it, in either the Old or New Testament, which deals with the gracious reconciliation and the remission of sins through faith for the sake of God's mercy in Christ, is the Gospel."
Martin Chemnitz, Loci Theologici, 2 vols., trans. J. A. O. Preus, St. Louis: Concordia Publishing House, 1989, II, p. 459.

"Therefore God, 'who is rich in mercy' [Ephesians 2:4], has had mercy upon us and has set forth a propitiation through faith in the blood of Christ, and those who flee as suppliants to this throne of grace He absolves from the comprehensive sentence of condemnation, and by the imputation of the righteousness of His Son, which they grasp in faith, He pronounces them righteous, receives them into grace, and adjudges them to be heirs of eternal life. This is certainly the judicial meaning of the word 'justification,' in almost the same way that a guilty man who has been sentenced before the bar of justice is acquitted."
Martin Chemnitz, Loci Theologici, 2 vols., trans. J. A. O. Preus, St. Louis: Concordia Publishing House, 1989, II, p. 482. Ephesians 2:4

"Yet these exercises of faith always presuppose, as their foundation, that God is reconciled by faith, and to this they are always led back, so that faith may be certain and the promise sure in regard to these other objects. This explanation is confirmed by the brilliant statement of Paul in 2 Corinthians 1:20: 'All the promises of God in Christ are yea and amen, to the glory of God through us,' that is, the promises concerning other objects of faith have only then been ratified for us when by faith in Christ we are reconciled with God. The promises have been made valid on the condition that they must give glory to God through us."
Martin Chemnitz, Loci Theologici, 2 vols., trans. J. A. O. Preus, St. Louis: Concordia Publishing House, 1989, II, p. 495. 2 Corinthians 1:20

"Therefore this apprehension or acceptance or application of the promise of grace is the formal cause or principle of justifying faith, according to the language of Scripture."
Martin Chemnitz, Loci Theologici, 2 vols., trans. J. A. O. Preus, St. Louis: Concordia Publishing House, 1989, II, p. 502.

"We must note the foundations. For we are justified by faith, not because it is so firm, robust, and perfect a virtue, but because of the object on which it lays hold, namely Christ, who is the Mediator in the promise of grace. Therefore when faith does not err in its object, but lays hold on that true object, although with a weak faith, or at least tries and wants to lay hold on Christ, then there is true faith, and it justifies. The reason for this is demonstrated in those lovely statements in Philippians 3:12: 'I apprehend, or rather I am apprehended by Christ' and Galatians 4:9: 'You have known God, or rather have been known by God.' Scripture shows a beautiful example of this in Mark 9:24: 'I believe; help my unbelief.'"
Martin Chemnitz, Loci Theologici, 2 vols., trans. J. A. O. Preus, St. Louis: Concordia Publishing House, 1989, II, p. 503. Philippians 3:12; Galatians 4:9; Mark 9:24.

"For we are not justified because of our faith (propter fidem), in the sense of faith being a virtue or good work on our part. Thus we pray, as did the man in Mark 9:24: 'I believe, Lord; help my unbelief'; and with the apostles: 'Lord, increase our faith,' Luke 17:5."
Martin Chemnitz, Loci Theologici, 2 vols., trans. J. A. O. Preus, St. Louis: Concordia Publishing House, 1989, II, p. 506 Mark 9:24; Luke 17:5.

"But because not doubt but faith justifies, and not he who doubts but he who believes has eternal life, therefore faith teaches the free promise, which relies on the mercy of God for the sake of the sacrifice of the Son, the Mediator, and not on our works, as Paul says in Romans 4:16: 'Therefore it is of faith, that the promise might be sure according to grace.'"
Martin Chemnitz, Loci Theologici, 2 vols., trans. J. A. O. Preus, St. Louis: Concordia Publishing House, 1989, II, p. 507. Romans 4:16

"Thus when we say that we are justified by faith, we are saying nothing else than that for the sake of the Son of God we receive remission of sins and are accounted as righteous. And because it is necessary that this benefit be taken hold of, this is said to be done 'by faith,' that is, by trust in the mercy promised us for the sake of Christ. Thus we must also understand the correlative expression, 'We are righteous by faith,' that is, through the mercy of God for the sake of His Son we are righteous or accepted."
Melanchthon, Loci Communes, “The Word Faith.” Cited in Martin Chemnitz, Loci Theologici, 2 vols., trans. J. A. O. Preus, St. Louis: Concordia Publishing House, 1989, II, p. p. 489.



Jacob Andreae, Concordist

"Concerning the article on the justification of the poor sinner in God's sight, we believe, teach, and confess on the basis of God's Word and the position of our Christian Augsburg Confession that the poor, sinful person is justified in God's sight—that is, he is pronounced free and absolved of his sins and receives forgiveness for them—only through faith, because of the innocent, complete, and unique obedience and the bitter sufferings and death of our Lord Jesus Christ, not because of the indwelling, essential righteousness of God or because of his own good works, which either precede or result from faith. We reject all doctrines contrary to this belief and confession." J
Jacob Andreae, Confession and Brief Explanation of Certain Disputed Articles. Cited in Robert Kolb, Andreae and the Formula of Concord, St. Louis: Concordia Publishing House, 1977, p. 58.

"Indeed, it has been proved more than sufficiently from the Scriptures of the prophets and apostles in the Old and New Testaments that the righteousness which avails in God's sight, which poor sinners have for comfort in their worst temptations, cannot and should not be sought in our own virtues or good works; nor will it be found there, as was proved above against the papists. Instead, it should be sought only in Christ the Lord, whom God has made our righteousness and who saves all believing Christians and makes them righteous through knowledge of Him."

"That is enough on the first article concerning which the theologians of the Augsburg Confession have quarreled with each other. Although it was a very scandalous controversy, nonetheless God, who lets nothing evil happen if He cannot make something good out of it, has produced this benefit for His church through the controversy: The chief article of our Christian faith, on which our salvation depends, has been made clear, so that there is not a passage in the Old or New Testament which has not been considered and discussed."
