BY PHILIP MELANCHTHON (FROM THE 1535 LOCI COMMUNES), TRANSLATED BY SCOTT L. KEITH, PH.D., EDITED BY KURT WINRICH
As I have said previously, the Gospel is the highest teaching of repentance and remission of sins on account of Christ. Therefore, concerning justification, I say predominantly this: The Gospel wars with sin and teaches that we need Christ to be our Mediator, for it is on account of Christ we are granted remission of sins and reconciliation.
If such is the case, it follows unavoidably: one cannot speak of justification without also speaking of remission of sins. Sadly, there are some (buffoons, I say!) who, with many words, have explained justification, all while making no mention of the remission of sins—as if it had no bearing on the matter! And yet these same people believe that God moves the hearts of infants and sanctifies them when they are brought to Him in baptism!
But we digress. Here we are speaking of adults, who, according to the teaching of the Gospel, are those who must believe in accordance with the express will of God. That is, their terrified mind must rest in the knowledge that sins are forgiven freely, through mercy and grace, on account of Christ. And they must similarly know that this free forgiveness is not given on account of the dignity, sincerity or strength of their contrition, or their love, or any other of their works. In this way, God changes our minds by faith and gives reconciliation and the forgiveness of sins.
If this is not the case—and the judgment finally is that it is sufficient that we have remission of sins as a result of our contrition or our love—our minds would be driven to despair, never knowing if we have enough contrition or love. Therefore, that we may have a sure and firm consolation, free remission of sins does not depend on us at all, but solely on the mercy and grace promised, on account of Christ.
These concepts would be nothing absurd, difficult, or complicated if the Scriptures were regularly and sufficiently engaged in the churches. If so, it would be well known that attributing any merit to our works serves only to make the remission of sins uncertain. Even better, the people of our churches would be comforted in the fact that remission of sins is a gift—not dependent on our works—and therefore is completely certain.
So, in that spirit of engagement, let us look more deeply at the word “justification”, which we contend points to the cause. We say justification signifies remission of sins and reconciliation (or acceptance) of the person to eternal life. Is this what the Scriptures mean?
To start, note that for the Jews of Jesus’ time, justification was a forensic word, “forensic” meaning having to do with judgments in courts of law. So, if I said, “Scipio has been justified from the accusations of the tribunals and the Roman people,” that would indicate that he has been pronounced righteous or absolved.  Therefore, when Paul uses the words “to be justified,” we take these to mean, according to the 1stcentury Jewish understanding, reconciliation and the remission of sins (i.e., absolution). Furthermore, when God remits sins, He simultaneously gives the Holy Spirit, who creates new virtues in the faithful. So we freely believe, teach and confess—and with a clear voice—that it is not only faith that should exist in the faithful, but also more fruit of the Spirit. But that’s another topic, of which we shall speak later. For now, it seems clear that this forensic understanding of justification means remission of sins is ours neither because of our decision nor because of our dignity or merit. Rather, it is a gracious pronouncement, apprehended through faith.
Doubtless, for Paul, faith—as this “cause” of justification—signifies trust in promised mercy on account of Christ. Even while some (cheaters and fools, I say!) thoroughly and loudly protest and deny that faith means to trust in mercy and grace, I doubt, however, that any of them appeal to learned and virtuous men for this opinion. Jan van Campen, a wise man (even though he sometimes criticizes us in this discussion), rather prudently sees this. That is, in Paul, [faith] must be understood as this same confidence in mercy. This demonstrates that my interpretation is fair. Of course we do not exclude the knowledge of the history of Christ and His saving person and work, as some falsely accuse us of doing. For when we say confidence in mercy promised on account of Christ, I certainly embrace all the articles of faith, and we certainly too refer to that article that is the history of Christ, which brings to mind the benefits of Christ, that is, the forgiveness of sins. Therefore, this [faith] includes both trust and knowledge of Christ the Son of God, as well as action (or habit) of the will, by which it receives the promise of Christ, and thus, acquiesces in Christ. This sets aside fancy rhetoric. This faith, therefore, signifies trust in the mercy of God, which by example bears witness. 
So we speak here of faith in the context of justification. And we reiterate that this is from the teachings of Paul. Paul conveys the promise of grace and faith, and we take hold of this promise through faith. Furthermore, this faith is trust in the mercy of God. Trust, in this whole debate, looks down on our merit, and requires confidence in a righteousness not of ourselves—an alien righteousness—namely, the righteousness of Christ. Now if Paul thought that man was righteous (i.e., acceptable to God or reconciled) on account of his dignity, qualities, or works, he would have taught that he had confidence in his own merit. On the contrary, it is known that he says in Romans 3:27: “Then what becomes of our boasting? It is excluded.” Again, he calls us to Psalm 32:1: “Blessed is the one whose transgression is forgiven, whose sin is covered.” And so, we are immediately pronounced righteous when we believe that our sins are forgiven. Now this faith, which confesses that sins are remitted, is the trust of which we speak. Also with what is said in Romans 5:1: “Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ.” For this is contrasted with the knowledge of the law, of which it is said in Romans 4:15: “For the law brings wrath, but where there is no law there is no transgression.”
Although the arguments from works are common and natural, faith is contrasted in that it always signifies trust in the mercy of God, promised on account of Christ. We certainly believe in this article as the remission of sins. Furthermore, the “common and natural” opinion is reprehensible, because it delivers nothing but doubt about whether we have remission of sins. Faith, therefore, is intimately connected to God’s mercy: indeed, God’s mercy is the object of faith. This is why it is said that we are justified by faith. So that the figure of speech may be rightly understood, let me say it this way: justification is by the mercy of God promised on account of Christ, but this mercy is grabbed hold of by faith. I encourage you to read again Romans chapter 3, where Paul says that man is reconciled not on account of the dignity or qualities of their works, but by trust in an alien righteousness.
 The Oxford Classical Dictionary, eds. M. Cary, et al (Oxford: Clarendon Press, 1949), 815. “Scipio Africanus Major, Publius Cornelius (236–184 B.C.), son of Publius. In 199 Scipio was elected censor and became princepes senatus. A keen supporter of a philhellinic policy, he prudently but vainly urged in his second consulship (194) that Greece should not be completely evacuated lest Antiochus of Syria should invade it. In 193 he was sent to Carthage to investigate a frontier dispute between Carthage and Masinissa. When his brother Lucius was given command against Antiochus (190), Africanus, who could not constitutionally yet be reelected consul, was ‘associated’ with the command. After crossing to Asia, where he received back from Antiochus his captured son Lucius, Scipio fell ill and took no active part in his brother’s victory at Magnesia (189). Meanwhile in Rome, political attacks, led by Cato, were launched on Scipios, culminating in the ‘Trials of the Scipios,’ on which the ancient evidence is conflicting. Africanus intervened when Lucius was accused in 187; whether he himself was formally accused either in 187 or 184 is doubtful. But his influence was undermined and he withdrew embittered and ill to Liternum where he died soon afterwards (184).” See also: W. Schur, Scipio Africanus und die Begründung der römischen Weltherrschaft (1927); H. H. Scullard, Scipio Africanus in the Second Punic War (1930).
 Melanchthon uses the Latinized version of his name “Campensis.” See Peter G. Bietenholz, and Thomas Brian Deutscher, Contemporaries of Erasmus—A Biographical Register of the Renaissance and Reformation, 3 vols. in The Collected Works of Erasmus(Toronto: University of Toronto Press, 1995), vol. 1, 255. “Jan van Campen (Campensis), who was descended from a respected family from Kampen, in Overijssel, completed his education in the University of Louvian, where he may have been preparing for a theological degree and the priesthood as early as 1509. The independent and scholarly bent of his mind led him to focus on the study of the Bible and of Hebrew. He had shown interest in the early works of Luther and Melanchthon, but it does not seem that even the Louvain theologians found any reason to question his orthodoxy.”
 For Melanchthon, saving faith (fides salvifica or fides propria) is a true personal faith made of three parts: (1) notitia or knowledge of the historical Christ and His saving person and work; (2) assensus, assent to the intellectual truth of that knowledge; and (3) fiducia, or trust; that is, a faithful confidence which, by an act of the changed will, appropriates savingly the mercy of God shown on those who trust in Him on account of Christ. Saving faith cannot, therefore, be merely historical or intellectual—it is volitional.
