What does it mean to be human? The German theologian Dietrich Bonhoeffer thought deeply about this questions out of a desire to understand the importance of Christ and the incarnation for modern culture. His conviction that Christ died for a new humanity is at the core of his theological anthropology. This collection assembles a distinguished and international group of scholars to examine Bonhoeffer’s understanding of human sociality. From the introduction of his dissertation, Sanctorum Communio, where he notes ‘the social intention of all the basic Christian concepts’, to his final writings in prison, where he describes Christian faith as being for others, the theme of human sociality runs throughout Bonhoeffer’s works. This volume examines Bonhoeffer’s rich resources for thinking about what it means to be human, to be the church, to be a disciple, and to be ethically responsible in our contemporary world. Being Human, Becoming Human is vital reading for Bonhoeffer scholars as well as for those invested in theological debates regarding the social nature of human beings.
