Edgar introduces his readers to the apologetics of Cornelius van Til, who was one of the original apologists of the twentieth century. His approach to apologetics has become known as presuppositionalism. Edgar further provides an overview of the most prominent characteristics of Van Til’s method of apologetics.

What is Reformed theology? What does it mean to adhere to the Reformed faith? Do Reformed theologians claim that there is one all-encompassing summary of the Reformed faith? In Chapter 1 William Edgar claims that part of the task of ordering our theological ideas is to assign a centre and then move toward the periphery. At the heart of Reformed theology is the desire to credit all good things to God. Chapter 1 is a reflection on the significance of this desire and claim.

The purpose of this volume is to provide primary sources from important authors with an apologetic concern. Chapter 1 provides an excerpt from Martin Luther, Concerning Christian Liberty (or On Christian Freedom), written in 1520. This work extols one of Luther’s central theological themes: justification by grace through faith. The excerpt is preceded by an introduction to the historical and theological context in which the work of Luther appeared.
