A New Look at the Theology of the Cross: What It Meant for Luther and Its Significance for Us Today
Jeffrey Silcock
Introduction
The theology of the cross (theologia crucis) is one of the most popular of Lutherâs teachings. Outside the Lutheran tradition, it is usually understood as nothing more than a restatement of the atonement, as developed by Paul, whose mission it was to preach nothing else except Jesus Christ, and him crucified (1 Cor 2). But in Lutheran theology, the cross has a deeper meaning, for it is precisely in Godâs act of self-revelation culminating in the cross that God conceals himself most deeply in a way that reason will never understand. This, as we will see, is the paradoxical heart of Lutherâs theology of the cross. Although we cannot discuss it here, this theology provides an important approach to the problem of suffering. It also enables us to see how God is at work in a hidden way in the church and its ministry, despite its apparent weakness, public ridicule, and in recent decades rapid shrinkage.
However, several prominent Luther scholars question if this reading of Lutherâs theology of the cross is in fact historically accurate. These scholars argue that, far from being central to his theology, the theologia crucis, as Luther develops it in 1518, virtually disappears from his thought by 1520. In this paper, I will explore whether there is a truth to this claim and if so, what these scholars mean by Lutherâs theology of the cross and how their understanding of it relates to that of the standard interpretation that prevails in much of Luther scholarship today. As we will see, another matter that plays into this discussion is the question of whether Lutherâs theological breakthrough should be dated early (1513â15) or late (1518â19).1
The paper falls into four main sections. After a short introduction, I will begin by discussing the standard interpretation of the theology of the cross that sees it as central to Lutherâs mature reformational theology. In the second section, I will present the alternative view that the theologia crucis is not a central feature of his reformational theology at all, but belongs rather to his early pre-reformational theology, culminating in the Heidelberg Disputation. This will be followed by a third, longer section that critically assesses these two views to determine which is better supported by the texts and whether they can be brought into some sort of relationship to each other. The final section will consider the significance of the theology of the cross for today.
It is a curious fact that the term âtheology of the crossâ (theologia crucis) or âtheologian of the crossâ (theologus crucis) seems to occur in only six texts in the Luther corpus. Four of them were written in the early spring of 1518, namely, the Heidelberg Disputation2 (this has the most explicit and well-known of the references), Lutherâs Asterisks and Eckâs Obelisks3 (the English title of an untranslated Latin work), the Lectures on Hebrews,4 and The Explanations to the 95 Theses (Resolutiones).5 The fifth occurs in the Operationes in Psalmos (Lutherâs second series of lectures on the Psalms, 1519â21) in 1519. This comes less than a year later and follows closely the emphasis Luther makes in the other four texts, even if it has some different accents. The sixth text, which has recently been identified, comes from 1532/33, some fifteen years after Heidelberg. The key question here, as we will see, is whether this text, although it uses the term âtheology of the crossâ, still fits the pattern of the other five from 1518â19. The fact that all of the texts that use the term come from Lutherâs early period, except for the last one mentioned, is an important datum for those who argue that the theology of the cross, as Luther understands it in 1518, does not belong to his mature, reformational theology.
1. Standard Interpretation of the Theology of the Cross
The standard view of Lutherâs theologia crucis is based on the interpretation of scholars like Paul Althaus,6 Walther von Loewenich,7 Gerhard Ebeling,8 and Alister McGrath,9 among others. Not all writers agree with each other in every aspect of their Luther interpretation, but they all agree that the theology of the cross belongs to his mature theology and not simply to one stage of his theological development.10
The main features of the theology of the cross, according to this view, can be summed up under five key themes.11 (1) The theologia crucis is a theology of revelation and is aimed specifically at scholastic theology that puts great store by reason. Rather than seeking God where he has revealed himself in the death of his Son on Calvary, it attempts to know God by way of philosophical speculation based on natural law. (2) Godâs revelation is paradoxical, contrary to human reason. When he reveals himself, he also conceals himselfâso deeply in fact that he can only be apprehended with the eyes of faith. Like Moses, who was denied a vision of Godâs glory (Exod 33:23), we too cannot see Godâs face but only his back (posteriora Dei). We cannot know God as he is in himself, but only as he is hidden in his revelation. (3) Again, like Moses, we are denied a direct knowledge of God. Instead, we see God in faith revealed in the cross, the posteriora Dei revealed in the humility and shame of Calvary. The things that we can see are the very things that human wisdom regards as the opposite of deity, such as weakness, foolishness, and humility. To those without faith, this revelation is concealed. Godâs presence in the cross of Christ cannot be empirically verified by human reason. However, those who have faith know that concealed in the humility and shame of the cross are the power and glory of God. His strength is revealed in apparent weakness, his wisdom in apparent folly, and his mercy in apparent wrath. (4) The theology of the cross stresses that God is known especially through suffering and the crossâboth Christâs and the Christianâs. (5) The theologia crucis rejects not only the rationalistâs attempt to know God through reason but also the moralistâs attempt to reach God through obedience to the law.12 For as Luther says in the Heidelberg Disputation, âtrue theology and recognition of God are to be found [only] in Christ crucifiedâ.13
A brief elaboration of some of these themes, on the basis of standard works, should be sufficient since this understanding of the theologia crucis is already well known to most people who are familiar with the basics of Lutherâs theology.14 The theology of the cross in 1518 does not simply highlight Christâs death on Calvary nor does it just explicate the doctrine of the atonement, but it specifically refers to that type of theology which stands in stark contrast to the theology of glory. These are not simply two different, but equally valid, ways of doing theology, but they are more like two different religions; one is true, the other false.15
Theologians of the cross see God differently from the theologians of glory. As we saw above, Moses, who was denied a vision of Godâs face (that is, Godâs glory) exemplifies the theologians of the cross, who can only see God from behind, in a hidden way. The theologians of glory, on the other hand, are typified by the scholastics of Lutherâs day who tried to reach God through philosophy, that is, reason and speculation.
Godâs revelation is contrary to human reason and defies logic. According to unregenerate human reason, God is omnipotent, transcendent, and detached from this world. The theology of the cross, on the other hand, takes its stand on scripture and through faith confesses that God reveals himself by concealing himself in the opposite of what reason would expect. So, in Jesus Christ, the almighty God becomes a helpless infant born in a manger;16 he comes not as a king but as a servant. He dies the death of a criminal on a Roman crossâyes, paradoxically, God dies. But to unbelievers, his death is only the death of another crazy messianic pretender who was betrayed by his own people to the Roman authorities and whose cross is only one of thousands that dotted the Judean hillside. Yet faith points to this blood-streaked and God-forsaken man on the gallows and confesses, with the soldier under the cross, âTruly, this man was the Son of Godâ (Mark 15:39). In all of this, faith sees in the cross divine power hidden under human weakness,17 glory concealed behind ignominy and shame, divine wisdom hidden behind the folly of the cross, as the apostle emphatically describes it in 1 Cor 1:18â31, which is Paulâs statement of the theology of the cross. But according to the theologia crucis, the revelation of God is not only hidden but paradoxical. God acts in a way that defies all our expectations based on natural religion, reason, and philosophy. In fact, according to the theology of the cross, God is absconditus sub contrario (hidden under his opposite).18
This leads to profound Anfechtung19 in the Christian life, which is another hallmark of the theologia crucis. Christians who through the law feel only Godâs accusation and wrath because of sin are called to turn away from the voice of the law and to put their trust in that other word that God speaks, the word of gospel,20 which declares and bestows the forgiveness of sins. The Anfechtung arises when Satan uses the law to create doubt in the mind of Christians who have been absolvedââDid God really say that? What gives you the right to think you are forgiven? Do you think God turns a blind eye to sin?â With words like these, the evil one attacks the conscience and tries to get the believer to doubt Godâs word of grace. According to the theologia crucis, the Christian life is stamped by spiritual attack in which Christians are called to turn away from the God of wrath and to find refuge in the God of mercy; in faith, they are to appeal to God against God, just as Christ did on Calvary, in his great hour of temptation, when he was forsaken by God the Father (Matt 27:46).21
The theology of the cross has implications for all facets of Christian doctrine and life: Godâs omnipotence is hidden under the weakness of his crucified Son, his glory under the shame and disgrace of the cross, victory under defeat, the holiness of Christians under their continuing sinfulness (simul iustus et peccator), the wisdom and power of God under the apparent foolishness and weakness of his word, which looks and sounds all too ordinary in a church which, to the natural eye, looks anything like the glorious saints of the new creation. The cross stands for Godâs hidden and paradoxical revelation, which can only be seen with the eyes of faith.
Within a year of his Heidelberg Disputation, Luther says, in his later lectures on the Psalms, âThe cross of Christ is t...
