Jim Cassidy discusses Therefore the Truth I Speak: Scottish Theology, 1500–1700 by Donald Macleod. The Scottish church was forever altered by the arrival of the Reformation in the sixteenth century. Its legacy endured, and provoked a flurry of theological re–examinations which form the foundation for much of our modern understanding of Reformed Theology. In this informed and accessible historical study, Donald MacLeod, one of Scotland's current leading theologians, looks to the past to assess the impact of prominent theologians of the sixteenth and seventeenth centuries, always with an eye to demonstrating how their writings speak to contemporary challenges facing the Church today.
