The Thinker and His Revolution
Karl Barth (1886-1968), born in Basel, Switzerland, and educated at the universities of Bern, Berlin, Tubingen, and Marburg, was the most influential Protestant theologian of the twentieth century and arguably the most significant since the Reformation. His Church Dogmatics (Kirchliche Dogmatik, abbreviated KD), published in thirteen part-volumes between 1932 and 1967, totals approximately six million words - the longest systematic theology ever written. It represents the most sustained and comprehensive attempt in modern thought to reconstruct all of theology, philosophy, ethics, and anthropology from the single starting point of God's self-revelation in Jesus Christ as attested in Scripture.
Barth's theological revolution began in 1919 with the publication of his commentary on Romans (Der Romerbrief), which he revised drastically in 1922. The book 'fell like a bomb on the playground of the theologians,' as Karl Adam put it. Barth's target was liberal Protestant theology - the tradition of Schleiermacher, Ritschl, and his own teacher Wilhelm Herrmann - which had reduced Christianity to religious experience, moral idealism, or cultural values. The crisis of World War I, when Barth's liberal teachers signed a manifesto supporting the Kaiser's war policy, convinced him that a theology grounded in human experience rather than divine revelation was incapable of prophetic resistance.
Biblical Texts Engaged
John 1:14 - 'And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth' (KJV) - is the Christological center of the entire Church Dogmatics. For Barth, this verse contains the whole of theology in nuce: God is known not through nature, reason, religious experience, or philosophical argument, but exclusively through the incarnation of the eternal Word in Jesus Christ. The Word that 'was made flesh' is the same Word through which 'all things were made' (John 1:3) - the God who reveals himself in Christ is the God who created and sustains the universe.
John 14:6 - 'Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me' - grounds Barth's exclusivist Christology. All genuine knowledge of God comes through Christ; there is no 'natural theology' - no knowledge of God available apart from Christ. This conviction put Barth in direct conflict with Emil Brunner, his former ally, in the famous 'Nein!' exchange of 1934, and with the entire Catholic tradition of natural theology from Aquinas onward.
Romans 1:16-17 - 'For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth... For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith' - was the text that launched Barth's theological revolution. His Romans commentary argued that the 'righteousness of God' is not a human quality or achievement but God's own action, breaking into human history 'vertically from above' like a bomb crater.
Barth also draws extensively on the Old Testament, particularly the creation narratives (Genesis 1-2, which he reads Christologically - creation is the 'external ground of the covenant'), the election of Israel (Deuteronomy 7:6-8), and the prophetic tradition. His exegesis of Genesis 1 in KD III/1 runs to over 300 pages.
Core Argument
The Church Dogmatics is organized around four doctrines (only three were completed): the doctrine of the Word of God (KD I), the doctrine of God (KD II), the doctrine of creation (KD III), and the doctrine of reconciliation (KD IV; the planned fifth volume on redemption was never written).
The doctrine of the Word of God (KD I/1, 1932; I/2, 1938) establishes the methodological foundation. Barth distinguishes three forms of the Word of God: the revealed Word (Jesus Christ), the written Word (Scripture), and the proclaimed Word (preaching). Scripture is not itself revelation but the witness to revelation - the human, fallible, historically conditioned testimony to God's self-disclosure in Christ. This is why Barth insists on calling his work 'Church Dogmatics' rather than 'Christian Dogmatics' - theology is an activity of the Church, accountable to Scripture, not a private intellectual enterprise.
The doctrine of God (KD II/1, 1940; II/2, 1942) develops Barth's revolutionary doctrine of election. In classical Reformed theology (Calvin, the Westminster Confession), God eternally elects some individuals to salvation and others to damnation (double predestination). Barth radically reinterprets this doctrine: Jesus Christ is both the electing God and the elected human being. In Christ, God elects to take the burden of reprobation upon himself. Election is not an arbitrary divine decree but the expression of God's grace: 'In the beginning with God was this One, Jesus Christ. And that is predestination' (KD II/2, p. 145). This Christological reconstruction of election has been called 'the most significant theological development of the twentieth century' (Bruce McCormack).
The doctrine of creation (KD III, 1945-1951, four part-volumes) argues that creation is the 'external ground of the covenant' - God creates the world in order to enter into relationship with it through Christ. Barth rejects natural theology in its entirety: the created world does not provide independent evidence for God's existence. Creation is known as God's creation only through revelation.
The doctrine of reconciliation (KD IV, 1953-1967, three completed part-volumes plus fragments) is the dogmatic center. Barth analyzes reconciliation through three Christological movements: the humiliation of the Son of God (Christ's descent into human sin and suffering), the exaltation of the Son of Man (humanity's elevation through Christ's resurrection), and the unity of the divine-human in the one person of Jesus Christ. Each movement generates corresponding doctrines of sin, justification, sanctification, and ecclesiology.
Intellectual Context
Barth's primary target was liberal Protestant theology in all its forms. Friedrich Schleiermacher (1768-1834), the 'father of liberal theology,' had grounded religion in the 'feeling of absolute dependence' - making human experience the starting point and norm of theology. Albrecht Ritschl (1822-1889) had reduced Christianity to moral values. Adolf von Harnack (1851-1930) had distilled the 'essence of Christianity' to the fatherhood of God and the brotherhood of man. Barth rejected all of these as forms of anthropology masquerading as theology.
The political dimension was inseparable from the theological. In 1934, Barth was the principal author of the Barmen Declaration, the founding document of the Confessing Church, which rejected the Nazi-aligned 'German Christians' and affirmed the exclusive lordship of Christ: 'Jesus Christ, as he is attested for us in Holy Scripture, is the one Word of God which we have to hear and which we have to trust and obey in life and in death.' The first thesis of Barmen, grounded in John 14:6 and John 10:1-9, was a direct theological challenge to the Nazi claim on total allegiance.
Barth engaged extensively with philosophy, though always critically. He rejected Heidegger's existentialist ontology, Bultmann's existentialist hermeneutics, and Tillich's 'method of correlation' - all of which, in his view, allowed a philosophical framework to determine the shape of theology. For Barth, theology must follow its own object - the self-revealing God - not any philosophical method.
Reception and Critique
Barth's reception has been enormous and contested. Within Protestant theology, he launched the 'neo-orthodox' movement (though he disliked the label), which dominated mainline Protestantism from the 1930s through the 1960s. His students and associates - Dietrich Bonhoeffer, Rudolf Bultmann (who broke with Barth over hermeneutics), Emil Brunner (who broke with Barth over natural theology), Thomas F. Torrance, Eberhard Jungel - constitute a who's who of twentieth-century theology.
Catholic reception was initially hostile but became increasingly appreciative. Hans Urs von Balthasar's The Theology of Karl Barth (1951) was the first major Catholic engagement, arguing that Barth's theology, properly understood, was closer to Catholicism than either side recognized. Henri Bouillard and Hans Kung (Justification: The Doctrine of Karl Barth and a Catholic Reflection, 1964) argued that Barth's doctrine of justification was compatible with the Council of Trent's teaching. The Second Vatican Council's emphasis on God's self-revelation (Dei Verbum, 1965) reflects Barthian influence.
Liberal Protestant critics (Paul Tillich, Schubert Ogden) argued that Barth's rejection of natural theology and philosophical engagement made his theology a 'positivism of revelation' (Bonhoeffer's phrase) - an authoritarian imposition that refused to engage with modern intellectual culture. Feminist theologians (Rosemary Radford Ruether, Elisabeth Schussler Fiorenza) have critiqued Barth's complementarian view of gender relations in KD III/4.
Process theologians (Charles Hartshorne, John Cobb) reject Barth's classical theism - his insistence on God's absolute freedom and sovereignty - in favor of a God who is genuinely affected by and responsive to the world. Postliberal theologians (George Lindbeck, Hans Frei) drew on Barth's emphasis on Scripture's narrative character but criticized his residual foundationalism.
Legacy and Influence
The Church Dogmatics reshaped the world of Christian theology. Its most significant contributions include: the Christological concentration - the insistence that all theology must begin and end with Jesus Christ, not with human experience, reason, or nature; the revision of election - which transformed predestination from a terrifying decree into a gospel of grace; the rejection of natural theology - which created a sharp divide between Barthian and Thomistic approaches that persists today; the Barmen Declaration - which provided the theological foundation for Christian resistance to totalitarianism.
Barth's influence extends into ethics and politics. His theology of the 'command of God' (KD II/2 and III/4) argues that ethical obligation is not derived from general moral principles but from the specific command of the God revealed in Christ, addressed to particular persons in particular situations. This 'divine command ethics' has been developed by Oliver O'Donovan (Resurrection and Moral Order, 1986) and Nigel Biggar (The Hastening That Waits, 1993).
In the English-speaking world, Barth's influence was mediated by T.F. Torrance in Scotland, Reinhold Niebuhr and the Niebuhr brothers in America, and Geoffrey Bromiley, who translated the Church Dogmatics into English. Contemporary Barth scholarship - represented by Bruce McCormack (Karl Barth's Critically Realistic Dialectical Theology, 1995), George Hunsinger (How to Read Karl Barth, 1991), and the Karl Barth Society of North America - continues to produce important work.
Key Passages
From KD I/1, the doctrine of the Word of God: 'The Word of God is God Himself in Holy Scripture. For God once spoke as Lord to Moses and the prophets, to the Evangelists and apostles. And now through their written word He speaks as the same Lord to His Church. Scripture is holy and the Word of God, because by the Holy Spirit it became and will become to the Church a witness to divine revelation.'
From KD II/2, the doctrine of election: 'In its simplest and most comprehensive form the dogma of predestination consists, then, in the assertion that the divine predestination is the election of Jesus Christ. But the concept of election has a double reference - to the elector and to the elected. And so we have to understand the name of Jesus Christ in a double sense - as very God and very man... Jesus Christ is the electing God... Jesus Christ is the elected man.'
From the Barmen Declaration, Thesis 1: 'Jesus Christ, as he is attested for us in Holy Scripture, is the one Word of God which we have to hear and which we have to trust and obey in life and in death. We reject the false doctrine, as though the church could and would have to acknowledge as a source of its proclamation, apart from and besides this one Word of God, still other events and powers, figures and truths, as God's revelation.'
Contemporary Relevance
Barth's theology addresses several contemporary concerns. His rejection of natural theology challenges both the 'intelligent design' movement (which seeks to demonstrate God's existence from biological complexity) and the 'new atheism' (which assumes that theology is a species of natural science that has been refuted). For Barth, the question of God's existence is not answered by examining nature but by attending to God's self-revelation in Christ.
His Christological concentration offers resources for interfaith dialogue - not by finding common ground among religions (which Barth would reject as a form of natural theology) but by insisting that genuine encounter with the other requires clarity about one's own identity. His Barmen theology - the insistence that Christ's lordship relativizes all political claims to total authority - speaks to contemporary confrontations between Christianity and authoritarian populism.
The unfinished character of the Church Dogmatics - Barth never wrote the doctrine of redemption - is itself significant. The last fragment Barth dictated before his death in 1968 was a meditation on God's faithfulness: 'God is not a God of the dead but of the living. In Him they all live.' The incompleteness of the work points beyond itself to the God whose self-revelation always exceeds our capacity to systematize it.
