Thomas F. Torrance is considered by many to be the most important English-speaking theologian of the last fifty years. Torrance has written extensively (over six hundred items) on nearly every theme in theology, especially theological method and the nature of theology. Yet little secondary literature about his theology has been published to date. The significance of this book by Elmer M. Colyer is that it discusses a theme (the nature of doctrine) that takes readers into the heart of Torrance's critical realist epistemology, theological method and understanding of the nature and purpose of theology. Colyer also contributes significantly to the ongoing conversation concerning the nature of doctrine, since Torrance's understanding of doctrine moves considerably beyond the work of George Lindbeck (The Nature of Doctrine) and Alister McGrath (The Genesis of Doctrine) in this area.
