The best of evangelical Christian theology has always paid attention to the key thinkers, issues and doctrinal developments in the history of the church. What God has done in the past is key to understanding who we are and how we are to live. The purpose of this volume is threefold: to introduce a selection of key early and medieval theologians; to strengthen the faith of evangelical Christians by helping them to understand the riches of the church's theological reflection; and to help them learn how to think theologically. These essays offer insightful analysis of and commentary on each theologian, along with some critical assessment of how evangelicals should view and appropriate his insights. The contributors' intention is the cultivation of minds 'fired by the grace of our creator and saviour' (Augustine), so that we might think well and rightly about our good and great God and live in his light.
