There is perhaps no aspect of traditional Thomistic thought so contested in modern Catholic theology as the notion of predestination as presented by the classical Thomist school. What is that doctrine, and why is it so controversial? Has it been rightly understood in the context of modern debates? At the same time, the Church’s traditional affirmation of a mystery of predestination is largely ignored in modern Catholic theology more generally. Why is this the case? Can a theology that emphasizes the Augustinian notion of the primacy of salvation by grace alone also forego a theology of predestination?Thomism and Predestination: Principles and Disputations considers these topics from various angles: the principles of the classical Thomistic treatment of predestination, their contested interpretation among modern theologians, examples of the doctrine as illustrated by the spiritual writings of the saints, and the challenges to Catholic theology that the Thomistic tradition continues to pose. This volume initiates readers— especially future theologians and Catholic intellectuals—to a central theme of theology that is speculatively challenging and deeply interconnected to many other elements of the faith.
