Winds of Doctrine: The theology of Barth, Brunner, Bonhoeffer, Bultmann, Niebuhr, Tillich by Addison H. Leitch (Good, 1966, HC, 62 pgs, Fleming Revell)

Winds of Doctrine: The Theology of Barth, Brunner, Bonhoeffer, Bultmann, Niebuhr, Tillich provides a clear, readable analysis of six major 20th-century theologians.  Rather than offering an exhaustive study, the book aims to present the central concept or "key" that unlocks the entire theological work of each thinker. 

The book is structured to cover the following figures and themes:

• Karl Barth: Focuses on his neo-orthodox and dialectical theology, emphasizing God's absolute transcendence and revelation.
• Emil Brunner, Dietrich Bonhoeffer, and Reinhold Niebuhr: Grouped together as "Three Barthians" who reacted to or developed Barth’s ideas.
• Rudolf Bultmann and Paul Tillich: Analyzed for their contributions to existentialist theology and the reinterpretation of Christian doctrine in light of modern secular and scientific thought. 

Leitch’s work is described as an accessible introduction to doctrinal theology of the 20th century, helping readers understand the core tenets of these influential thinkers who sought to reinterpret traditional Christian faith for a 'modern' audience.
