Is there a centraldogma for the Protestant Reformation? It depends on what angle we attempt to answer that question by. For Martin Luther, per Barth’s lights et alia, the foundation for his reformational work was the doctrine of justification (sola fide). For Luther, according to Barth, this was the great differentiator between what became Protestantism versus the Latin Catholic church’s position on justification; which would entail a cooperative matrix in the God-human relation (gratia infusa). After Luther read the Greek New Testament for himself, he realized the synergistic salvation that Roma propounded was contradicted by the perspicacious teaching of Scripture alone. Barth offers some rich insight on how he sees this centraldogma operative for Luther:
It was again Luther, above all others, who obviously regarded and described the doctrine of justification as the Word of the Gospel. To him it was not merely the decisive point, the hub, as it were, of the whole of Evangelical theology in controversy with the Romanists. It was this, in the sense of the Schmalkaldic Articles of 1537 (Bek.-Schr. der ev.-luth. Kirche, 415 f.)—in which it is called the first and principial article in this special sense: “In relation to this article we cannot doubt or yield an inch, though heaven and earth or all things passing may fall . . . . On this article stands all that we teach and live against the Papacy, the devil and the devil prevail against us.” The fact that Luther linked together the Papacy, the devil and the world shows us, however, that Luther was not thinking merely in terms of the polemic against Rome. In the praefatio to the 1535 Galatians we are told immediately before the passage quoted earlier: That one article reigns in my heart, namely the article of faith in Christ, by which, in which, and through which all my theological reflections flow back and forth by day and by night. If the doctrine is flourishing, then will flourish all good things, religion, true worship, the glory of God, and assured knowledge of all conditions and matters (l.c., 39). Then in the argumentum of the same commentary we read (l.c., 48, 28): If the article of justification is lost, then the whole of Christian doctrine is lost at the same time. And on Gal. 1.3 (l.c., 72, 20): If the article of justification lies in ruins, then all lies in ruins. Therefore, it is necessary that we sharpen it (in the manner in which Moses spoke of the Law) and cram it in. For it cannot be understood and held enough or too much. According to Luther’s exposition of Gal. 2.20 (l.c., 296, 23) this article and this article alone has the power to refute all sects, anabaptists and sacramentarians, etc., seeing that they are all at error in relation to it. Moreover, it is by the position on justification that Christianity is distinguished from all other religions: For only Christians believe this doctrine and are righteous not because of what they themselves do, but because they receive the works of another, that is, the passion of Christ (Schol. on Is. 53.2f., 1534, W.A. 25, 329, 15; 330, 8). And in the same context (l.c., 332): this doctrine is the basis of the New Testament, from which, as from an open fountain, all the treasures of the divine wisdom flow. Similarly in 1537 Luther could open a disputation (W.A. 39.1, 205, 2) with the words: The article of justification is master and emperor, Lord, ruler and judge over all kinds of doctrines, and it preserves and steers all the church’s doctrine. If it does not know and consider this article, the human reason is defenceless against the vainest errors. But a mind which is strengthened by it will stand against all their assaults. The dominating role which Luther assigned to the matter in his own sermons and other works corresponds to these declarations of principle. The well-known description of the doctrine as the article by which the church stands or falls does not seem to derive from Luther himself, but it is an exact statement of his view. He found in it the one point which involved the whole.[1]
As Barth has illustrated, rather definitively, Luther saw the doctrine of justification as the watershed locus of all that mattered for the Church of Jesus Christ. For, if the Church gets the Gospel wrong, then what type of Church is one left with?
Once this spark lit on fire Luther’s affections his reformation was underway. It wasn’t the 95 theses on the Wittenberg church’s door that was motivating Luther—that is on the matter of the indulgences, per se, even as that was directly relatable to this matter—it went into the theoanthropological roots of the teaching of the New Testament itself. What was required for humanity to be justified before God? What in fact, were the fundamental entailments of the Gospel? Was it what the Latin church had taught Luther the Augustinian monk; the gratia infusa way? Or was it instead the iustitia aliena (alien righteousness) of Jesus Christ which when the would-be believer comes into union with Christ, by faith alone and grace alone (sola fide sola gratia), all of these benefits of Christ’s person and work become theirs? For Luther, and for the other reformers, it was clearly the latter; it was solo Christo (Christ alone). Soli Deo Gloria
