Letting God Be God: Karl Barth’s Journey with John Calvin

On the occasion of the 131st anniversary of the birth of Swiss theologian Karl Barth (1886–1968) and the yearlong commemoration of the 500th anniversary of the Protestant Reformation, we’d like to share some of Barth’s perspectives on John Calvin. The following is an article by Peter Anders, excerpted from The Reformation Then and Now: 25 Years of Modern Reformation Articles Celebrating 500 Years of the Reformation.

The Journey to Geneva: Calvin and Karl Barth

By Peter D. Anders

In 1909, Karl Barth became assistant pastor to the German congregation in Geneva. Preaching in the very auditorium and from the same pulpit as Calvin himself, and in the city then commemorating the 400th anniversary of Calvin’s birth, Barth couldn’t help but take a closer look at the theology of this celebrated Reformer. “It may have been the spirit of the place,” he recalls, “which caused me to deepen the experience I had gained from reading Schleiermacher again and again by making considerable inroads into Calvin’s Institutes.”[1] Barth did not experience any sudden conversion to Calvinism. He initially engaged Calvin from the perspective of his liberal theological education, seeking to “combine idealist and romantic theology with the theology of the Reformation.”[2] His early preaching focused on the Christian ethical task of manifesting the kingdom of God through the reformation of society, preaching he would later admit was also at odds with the Reformer’s teaching: “I’m afraid that Calvin would hardly have been very pleased at the sermons which I preached in his pulpit then.”[3]

Although there are important criticisms concerning Barth’s theological discontinuities with Calvin—and concerning Barth’s perception of later Reformed theology’s discontinuities with Calvin—it should not be overlooked that Barth’s early theological development was greatly influenced by Calvin’s theology. This theological journey to Geneva began in earnest only after Barth left Geneva. Through the difficult pastorate in Safenwil, the disillusionment of the First World War, and the frantic professorate at Göttingen, his determined journey toward Calvinism is representative of many who have traveled a similar road since the Reformation. With honesty and insight, Barth brings into focus the face of Calvin’s theology that compels such a journey.

Barth was confronted with the disturbing strangeness of Calvin’s theology. As he famously expressed in a 1922 letter to his lifelong friend, Eduard Thurneysen:

Calvin is a cataract, a primeval forest, a demonic power, something directly down from the Himalayas, absolutely Chinese, strange, mythological; I lack completely the means, the suction cups, even to assimilate this phenomenon, not to speak of presenting it adequately….I could gladly and profitably set myself down and spend all the rest of my life just with Calvin.[4]

Yet, while he sought to deal with this strangeness of Calvin, Barth also recognized that it is precisely in the challenge of its unfamiliarity that this theological orientation is so valuable: “The little bit of ‘Reformed theology’ that I teach is really nothing in comparison to the trumpet blast which needs to be blown in our sick time.”[5]

In Barth’s view, what is so strange about Calvinism is essentially what is so strange about the theology of the Reformation itself.

[It] did not fall victim to the illusion that gripped the whole of the middle ages and that has gained force again in the modern age, the illusion that there is a continuous path that leads step by step from an earthly city of God to the kingdom of heaven. For him [Calvin] the divine was always divine and the human always human.[6]

Calvin affirms both theology and ethics, yet always together in the serious and consistent application of the critical principle of God’s absolute and glorious sovereignty. Here Barth recognized that in Calvin’s theology it is “the glory of God itself that brought disaster to the theology of glory.”[7] He saw in Calvin the heart of the Reformation’s discovery that theology has to do with God.

The secret was simply this, that it took this theme seriously in all its distinctiveness, that it names God God, that it lets God be God, the one object that by no bold human grasping or inquiry or approach can be simply one object among many others. God is. He lives. He judges and blesses. He slays and makes alive [cf. 1 Sam. 2:6]. He is the Creator and Redeemer and Lord.[8]

For Barth, Calvinism is not a theology of symmetrical completeness, rational subtleties, or pietistic introspection, but a theology that continuously makes problems for us, asks questions, and establishes tensions that lead us from law to gospel, from what is impossible for humans to what is alone possible with God.

What Barth found so compelling in Calvin’s theology is what others also have found traveling the same road. Calvin’s theology is a passionate and creative drive toward synthesis, yet with no other agenda save the glory of God.[9] It is grounded in the truths of Holy Scripture, yet truths that are only apprehended through the Spirit and not merely through the careful employment of scientific methods of exegesis.[10] It possesses an apologetic power, yet “not an apologetics that seeks to justify Christianity before courts outside itself, for example, philosophy or science,” but one that “proceeds with the silent summons: Those who have ears to hear, let them hear! [Mark 4:9].”[11]

How far a Reformed and evangelical theologian can walk with Barth, and how far Barth actually walks with Calvin, are important contemporary issues. While this debate continues, so will Barth’s theological journey to Geneva continue to represent a road many others have traveled, as it brings into focus a face of Calvin’s theology that will compel many more to follow. 

Peter D. Anders is a systematic and historical theologian. He has taught at Talbot School of Theology, Gordon-Conwell Theological Seminary, and most recently at Gordon College in Wenham, Massachusetts.
