This book explores how Augustine and other important Church Fathers of Western and Eastern Christianity perceived the relationship between human freedom of choice and divine grace. It brings together a diversity of perspectives with contributions by experts of Patristic and Reformation theology. Several chapters focus on lesser-studied corpuses while others offer insights into less-known aspects of more familiar figures, each considering what faith, grace, and freedom might mean to early, and early modern, Christians. The volume reflects the complexity of the issue on the one hand, while on the other, it identifies a number of shared patterns that run through the history of philosophy and theology from late antiquity through the late Middle Ages to the Renaissance and the Reformation.
