Lutherâs Cross
Whenever most theologians think of âtheology of the crossâ today, the name of Martin Luther generally arises first. Theologia crucis is a signature motif both within Lutherâs theology itself and its subsequent legacy upon theology, philosophy, and the church. But it is also heavily contested ground. Luther himself understood the cross to have implications for both religion and politics. And the fact that he weaves both religion and politics together leads to some of the most powerful insights on both of his era.
The interest that Lutherâs own theologia crucis generates in contemporary theologians has kept the power of Lutherâs theological critiques of human pretension and politically oppressive theology alive. As we will see below, many theologians have used Lutherâs insights and inspiration to form a theology of the cross that speaks to their contexts. This seems natural: Luther wrote his theology because he was frustrated both with what he took to be the arrogance of theology of his day (which he thought forced Godâs word into overly systematized and domesticated philosophical categories, derived mostly from Aristotle and Aristotleâs Christian heir Thomas Aquinas) and with the power of the church to impose the implications of this theology with unchecked authority. One definition of power is the ability to impose oneâs fictions on someone else; Luther thought that the power of the church was to impose a fictitious, demanding God upon the people, and benefitting institutionally as a result.
That said, theologia crucis for Luther is a not a free-floating theme applicable to any given theological or political project; rather, it is best thought of as a specific theological orientation that allows the ordinary Christian as well as the theologian to live into the fullness of the Christian life in a manner that frees her to engage church tradition, ecclesial structures, and Godâs word while maintaining the primacy upon Godâs revelation of grace precisely in the brokenness and dejection of the cross. Luther was not anti-church or anti-government. But for Christians, he thinks that protest is needed when the church replaces the cross with a lust for power.
Likewise, we need to remember the medieval setting of Lutherâs views on good and evil. Lutherâs apocalyptic discourse concerning the beleaguered true church and its theology of the cross in opposition to the theology of glory that upholds the false testimony of Godâs enemies is neither metaphorical nor a stand-in for some more ânaturalâ reality. In the battle between the truth of the cross and the lies of the crossâs enemies, Luther understood nothing less than eternal salvation to be at stake, and the stakes remained high for him throughout his life. Whether or not contemporary theologians wish to operate in such dualistic terms, one cannot read Luther without remembering that, for him, perceiving the cross rightly truly is a matter of life and death.
Theology of the Cross vs. Delusions of Glory
This setting within the cosmic drama of judgment, damnation, and salvation helps us to understand the fact that Lutherâs tendency was to talk less about a given âtheology of the crossâ and more about a particular kind of stance towards theology as a whole. In Lutherâs main discussion of the theology of the cross specifically, the 1518 Heidelberg Disputation (written less than a year after the famous posting of the Ninety-five Theses that began Lutherâs rebellion against his churchâs selling of indulgences), it is in fact the theologian and not theology itself is what Luther is really interested in. The author herself, as much as the texts authored, are at the center of the discussion. This is why the famed theses 19 and 20 of the Heidelberg Disputation discuss, not âtheology of the crossâ per se, but rather the framework within which the theologian of the cross engages both the world and Godâs revelation. Here are the key theses along with their elaboration:
What does all this mean?
Notice, again, the emphasis is on the person thinking and not the thoughts that are thought. Luther is concerned first and foremost, not with what the theologian says, but with how the theologianâs perspective on God and the world is formed. This focus upon the person of the theologian and the optics by which she engages the things of God and the things of the world, as opposed to series of propositions that might be said to make up a âtheology of the cross,â supports the idea that for Luther the theologia crucis is a kind of interpretive lens by which in the tasks of exegesis, theology, and proclamationâand doing so with the goal of chastening the speculative impulse inherent in all these activities.
Chastened by what? By the epistemological and existential limits imposed by the fact that God chooses to be known to the world under the realities of pain, brokenness, and weakness. In other words, for Luther, there is no one set of tenets of propositions that makes up theologia crucis; it is more a kind of methodological bearing centered on the theologianâs positioning vis-Ă -vis the scandal of Godâs choosing to reveal saving truth in the form of brokenness and scandal. The cross gives us lenses to see God that are very different from what is on display in theologies of âglory,â those that can only associate God with what is pure, good, and holy.
To be sure, the medieval church in which Luther carried on his work was saturated at both the popular and theological levels with crucifixion imagery. However, Lutherâs great contribution was to flesh out with unparalleled vigor the notion that the cross must be a formative influence not only upon the content but also the form of thinking about God, and to apply this stricture with rigor and creativity to all aspects of the Christian life. In other words, Luther made the cross a cornerstone of Christian existence in the here and now. As a number of historians have pointed out, the actual term âtheology of the crossâ comes up often in Lutherâs early writings, but less in his later work. However, Luther retained and even expanded the substance of the term throughout the remainder of his life and writing career. In fact, careful reading demonstrates that the cross touches everything in Lutherâs theologyâand for Luther, at least, theology touches everything.
As regards Lutherâs understanding of the crossâs role in salvation, his model conforms broadly to what the Christian tradition terms âsubstitutionary atonement:â in Christ, God takes on the sin of humanity in such a way that those in Christ need no longer bear the punishment that the sin entails. Luther was fond of describing this as a kind of âhappy exchangeâ of the sin of humanity with Christâs perfectionâhumanity gets the benefit of Christâs perfection even as Christ takes humanityâs sins upon himself. However, what has been most influential in Lutherâs theology of the cross has not been the mechanics of how the cross saves, but rather the critical edge that the cross brings to theological projects that seek to minimize or distort the gospel of Godâs free gift of grace. That is, for Luther, theologizing about the cross is just as much about deconstructing bad theology as it is about paving the way for better theology.
Theologia Crucis and the Formation of the Theologian
The centrality of the cross was present as a theme even in Lutherâs thinking prior to the Reformation; his sermons between June 1516 and February 1517, immediately prior to the posting of the Theses, contain exhortations to âPreach one thing: the wisdom of the cross!â Later, his âExplanations of the Ninety-Five Thesesâ (completed in February 1518, amidst Lutherâs preparation for the debate at which the aforementioned Heidelberg Disputation was presented) makes it clear that the contrast between theologia crucis and theologia gloriae was not a one-off. It deeply informs how Luther thinks of theologyâs role in the church:
