Karl BarthKarl Barth (; ; – ) was a Swiss Reformed theologian who is most well known for his landmark ''The Epistle to the Romans'', involvement in the Confessing Church, authorship of the Barmen Declaration, and especially his five volume theological summa the ''Church Dogmatics'' (published in twelve part-volumes between 1932-1967). Barth's influence expanded well beyond the academic realm to mainstream culture, leading him to be featured on the cover of ''Time'' on April 20, 1962.
Karl Barth's theological career began while he was known as the "Red Pastor from Safenwil" when he wrote his first edition of his ''The Epistle to the Romans (1919)''. Beginning with his second edition of ''The Epistle to the Romans (1921)'', Karl Barth began to depart from his former training – and began to garner substantial worldwide acclaim – with a liberal theology he inherited from Adolf von Harnack, Friedrich Schleiermacher and others.. Barth influenced many significant theologians such as Dietrich Bonhoeffer who supported the Confessing Church, and Jürgen Moltmann, Helmut Gollwitzer, James H. Cone, Wolfhart Pannenberg, Rudolf Bultmann, Thomas F. Torrance, Hans Küng, and also Reinhold Niebuhr, Jacques Ellul, Stanley Hauerwas, and novelists such as John Updike and Miklós Szentkuthy. Among many other areas, Barth has also had a profound influence on modern Christian ethics. He has influenced the work of ethicists such as Stanley Hauerwas, John Howard Yoder, Jacques Ellul and Oliver O'Donovan. Provided by Wikipedia
