Pastors, church leaders, and students of Presbyterian polity will find this a useful guide to Presbyterian Church (U.S.A.) governance based on foundational principles. Recent changes in the PC(USA) Constitution have meant fewer rules and more flexibility in governance, making it imperative that leaders understand the historical principles that guide the church. Wilton explains the Book of Order's historic principles of church order in accessible language, providing readers with a lively appreciation of the revolutionary principles that guided the Presbyterian experiment in the New World and are still the beating heart of church life today. Principles of Presbyterian Polity, updated for the revised Directory for Worship, is written from the conviction that it is not enough merely to know the "what" of polity; a deep, intuitive understanding of the "why" is just as vital.
