Concepts of predestination and reprobation were central issues in the Protestant Reformation, especially within Calvinist churches, and thus have often been studied primarily in the historical context of the sixteenth and seventeenth centuries. In Versions of Election: From Langland and Aquinas to Calvin and Milton, David Aers takes a longer view of these key issues in Christian theology. With meticulous attention to the texts of medieval and early modern theologians, poets, and popular writers, this book argues that we can understand the full complexity of the history of various teachings on the doctrine of election only through a detailed diachronic study that takes account of multiple periods and disciplines.
