If theology at its best is knowing God and all things in the light of his reality, what is the nature of that knowledge? Of what can we be sure? Are there boundaries we must respect in pursuit of such understanding? To what extent can we know God, and what is the impact of that knowing? Little attention has been given in recent scholarship to the work of Emil Brunner (1889–1966), a Swiss pastor, professor, missionary, and theologian whose name is classed among the neo-orthodox thinkers of the last century. This lacuna is misleading, however, for his influence on modern theology persists. In Believing Thinking, Bounded Theology, Cynthia Bennett Brown explores the nature of and limits to theological thinking in Brunner’s own work. What results from this study is an encounter with a thoroughly biblical, warmly pastoral, carefully intellectual, and insistently Christocentric exposition of the Christian faith that remains relevant for theology and life today.
