Though this book isn’t new, 20th Century Theology (Downers Grove, IVP, 1992) by Stanley Grenz and Roger Olson is one of those books that theology students need to read, like it or not. It is basically a run-down of all the major theologians in the 20th century Western world (though a few transitional figures from the 19th century are also included). Grenz and Olson discuss men like Kant, Hegel, Barth, Brunner, Tillich, and Bonhoeffer, among others (Moltmann, Rahner, etc.).
Here are a few introductory blurbs to give you the general tenor of this book which summarizes some teachings of these theologians.
“We see twentieth-century theology as the story of theology’s struggle along with culture through this transition from modernity to postmodernity” (p. 10).
“The theology of the twentieth century, flowing as it does out of that of the nineteenth, offers an interesting case study in the attempt to balance these two aspects of the relation of God to creation (my note: the two are transcendence and immanence). In fact, the see saw of transcendence and immanence as a significant focus provides a handle for grasping the unity and diversity of the central current of theology that flowed through the century” (p. 12).
The book then unfolds first by discussing the Enlightenment and some aspects of 19th century theology. Grenz and Olson then take the trek through the 20th century theologians. I’ve enjoyed and appreciated this book which is a sort of textbook for those of us who want to get a good “feel” for what was happening theologically in the 20th century.
