While the term theologia crucis itself is most prominent in Luther’s early works, the later texts bear up the scholarly contention that the fundamental contrast between “cross” and “glory,” with its various methodological and theological implications, remains and is in fact amplified throughout Luther’s later writings. Indeed, considered topically, Luther’s treatment of virtually every significant theological locus throughout his canon—e.g., revelation, ecclesiology, and ethics is impacted by his understanding of the cross. “Theology of the cross” in Luther does not refer to a bound set of theological statements but rather a methodological stance in which epistemological fidelity to the modes in which God chooses to reveal himself—in suffering, death, and contradiction to expectation—marks the whole of the theologian’s orientation to knowledge of God and the world. While the theology of the cross in Luther’s deployment certainly touches on sociopolitical and ecclesial realities within his time, it is crucial for readers of Luther to understand that for him the motif was bound up within the total “thickness” of Christian life—the sacraments, prayer, discipleship, etc. In contrast to the temptation to treat the notion as a critical principle that can be detached from this total picture of Christian existence, scholarly attention to Luther must take seriously the ecclesiastically embedded character of theologia crucis—with all of the interweaving strands of inquiry that such embeddedness necessitates—in order to get the full picture of how Luther understood the cross’s impact on theology and the Christian life. The cross is also crucial theologically for Luther because it gets at the core of what he sees the theological project being able to do—deal with God in God’s self-revelation, under the confusing and sometimes seemingly paradoxical terms by which God chooses to engage humanity. Theologia crucis thus stands as the theological putting to death of the Old Adam—who is aligned, for Luther, with theologies of glory—so as to allow the theologian to hear and proclaim the gospel apart from pretension or undue speculation.
