This book is the first modern intellectual biography of the Scottish theologian and political theorist Samuel Rutherford (c. 1600-1661). Its main purpose is to provide a thorough discussion of Rutherford's religious and political ideas, and their role in the ideology of the Scottish Covenanters whose rebellion against Charles I marked the beginning of the British troubles in the mid-seventeenth century. The book also constitutes an important multidisciplinary case study in the Calvinist and Puritan traditions.
