A Definitive Biography of the Twentieth-Century ThinkerCertainly, in all my work my dependence upon my father will be visible, and, so I hope, a testimony to his life's work will be given. But on the whole, I have never attempted simply to represent or promote his work, but rather within the narrow frame of my competence in exegetical matters, to contribute to it. —Markus Barth, 1985

Though he has long been undervalued and remained in the shadow of his famous father, Markus Barth was a significant, groundbreaking thinker in his own right. He was a pastor, New Testament scholar, and theologian working in both Switzerland (Basel) and the United States (Dubuque, Chicago, and Pittsburgh), whose life intertwined with major developments in theology and modern history.

In this book, theologian Mark Lindsay provides the first biography of Markus Barth (1915–1994), eldest son of Karl Barth. Drawing from a hitherto unparalleled access to the extensive collection of Markus Barth's private letters and papers, including those in the Special Collections at Princeton Theological Seminary, Lindsay puts Barth's story and thought into historical context. He explores multiple aspects of Barth's life, including family and early years, pastoral work, scholarship, and enduring legacy. Lindsay identifies three main areas of Barth's contributions: his New Testament scholarship; his theology of the sacraments; and his pioneering, though not uncontroversial, work in Jewish-Christian relations.
