In The Spiritual Exercises of Saint Ignatius Loyola: Contexts, Sources, Reception, Terence O'Reilly examines the historical, theological and literary contexts in which the Exercises took shape. The collected essays have as their common theme the early history of the Spiritual Exercises, and the interior life of Ignatius Loyola to which they give expression.

The traditional interpretation of the Exercises was shaped by writings composed in the late sixteenth century, reflecting the preoccupations of the Counter-Reformation world in which they were composed. The Exercises, however, belong, in their origins, to an earlier period, before the Council of Trent, and the full recognition of this fact, and of its implications, has confronted modern scholars with fresh questions about the sources, evolution, and reception of the work.
