Jürgen Moltmann (born 8 April 1926) is a German Reformed theologian who is Professor Emeritus of Systematic Theology at the University of Tübingen. Moltmann is a major figure in modern theology and was the recipient of the 2000 University of Louisville and Louisville Presbyterian Theological Seminary Grawemeyer Award in Religion, and was also selected to deliver the prestigious Gifford Lectures in 1984–1985. He has made significant contributions to a number of areas of Christian theology, including systematic theology, eschatology, ecclesiology, political theology, Christology, pneumatology, and the theology of creation.Influenced heavily by Karl Barth's theology, Hegel's philosophy of history, and Ernst Bloch's philosophy of hope, Moltmann developed his own form of liberation theology predicated on the view that God suffers with humanity, while also promising humanity a better future through the hope of the Resurrection, which he has labelled a 'theology of hope'. Much of Moltmann's work has been to develop the implications of these ideas for various areas of theology. While much of Moltmann's early work was critiqued by some as being non-Trinitarian, during the latter stages of his career Moltmann has become known for developing a form of Social Trinitarianism. His two most famous works are Theology of Hope and The Crucified God. Moltmann also served as a mentor to Miroslav Volf.
