The theodicy of the remarkable Scottish Congregationalist theologian Peter Taylor Forsyth has long been recognized as a vital and significant contribution to twentieth-century theology. Up until now, however, there has not been a substantial full-length treatment of Forsyth's work on the problem of evil. The Theodicy of Peter Taylor Forsyth fills this lacuna by setting out, in a fairly systematic and comprehensive manner, Forsyth's justification of God in the face of evil. In so doing, it also illuminates several other related areas of his thought, such as his epistemology and Christology, as well as his understanding of sin, the atonement, providence, divine passibility, human origins, and the God-world relationship. Bringing Forsyth's approach to the subject into conversation with other prominent thinkers like Leibniz, Dostoyevsky, Camus, Moltmann, Hick, Bauckham, and Fiddes, this book also suggests ways in which Forsyth's justification of God contributes to the current state of Christian theodicy. It highlights Forsyth's ability to integrate insights from different approaches, even those that have hitherto generally been considered diametrically opposed notions. Forsyth's theodicy therefore presents an integrative approach to the topic, with every theme flowing from and returning to a clear center: the cross of Christ. As the book also makes clear, Forsyth considers theodicy to be an immensely practical discipline, with significant implications for human life. In every sense, therefore, it constitutes a "crucial" justification of the ways of God to humanity.
