This book explores how the great sixteenth- and early-seventeenth-century Jesuits read the secunda pars of the Summa theologiae. Their interpretation of Aquinas’s moral theology is shaped in part by their historical context, including the impact of the Protestant Reformation and the European discovery of the "New World," as well as new trade routes with Asia. The essays in this volume explore a wide variety of topics, including the natural desire to see God, infused moral virtues, freedom of conscience, faith and justification, doctrinal development, just war, slavery, the virtue of religion, Eucharistic sacrifice, sexual ethics, the theology of vocation, and natural law. The essays engage the thought of Francisco Suárez, Gabriel Vázquez, Luis de Molina, Francisco de Toledo, and various others. The underlying argument of the book is that this erudite, deeply Catholic and broadly Thomistic approach to ethics should be retrieved, given its Christian seriousness. Guided by divine revelation as taught in Scripture and Tradition, moral theologians in the Jesuit tradition ground themselves in Aquinas and in a rich understanding of natural law, universal moral norms, and the virtues, as well as in appreciation for spiritual interiority, conscience, and discernment.

Though the relationship between Jesuits and Dominicans has historically been marked by theological controversy, Ignatius of Loyola, the founder of the Jesuits, shows remarkable affinity for the Thomistic tradition, the tradition advanced above all by the Dominican order. When writing the Jesuit Constitutions, in fact, Ignatius made Thomas Aquinas’s Summa Theologiae the primary textbook for Jesuit theological formation. The contributions to this volume—originating from Jesuits, Dominicans, and lay scholars alike—explore different aspects of the complex yet illuminating relationship between Ignatius and Thomas. The themes range from the general relationship between the early Jesuits and scholastic theology to the attempts by Francisco de Toledo, the first Jesuit cardinal, to apply Thomistic reasoning to the religious and legal status of Jewish converts to Christianity. Other contributions compare Ignatius and Thomas on topics of significant interest for dogmatic, sacramental, and spiritual theology: spiritual experience, the ordering of the passions, the use of the imagination, prudence and discernment of spirits, frequent communion, Mariology, the “hierarchical church,” and the limits of obedience. Students of Ignatius of Loyola, Thomas Aquinas, second scholasticism, Christian-Jewish relations, and spiritual theology in general will find this volume an invaluable contribution.

Thomas Aquinas and Medieval Canon Law bridges, for the first time, two worlds of scholarship that have never been explored in book-length form and investigates an under-researched area in Thomistic studies, namely the question of how Thomas Aquinas engaged the ecclesiastical law and jurisprudence of his day. Neither historians of medieval canon law nor experts on Thomas's thought have previously paid much attention to the canon law tradition as a source for Thomas's work and an influence on his thought. But, as this volume shows, his consideration of mendicant life, law, justice, oaths, penance, clerical orders, the Eucharist, baptism, property, commerce, marriage and more reveal engagement with key canon law texts and concepts and with the jurisprudence of major canonists. The book uncovers how Aquinas encountered canonical regulations and jurisprudence as a Dominican, an educator in both theology and pastoral care, and a participant in the secular-mendicant controversy. In his life, education, community, and his way of thought, Thomas Aquinas could not avoid and necessarily encountered and dealt with the canonical tradition. He did so in a distinctive way, working as he did with his theological and philosophical source material to craft his own great synthesis. What this volume shows, if nothing else, is that the canon law tradition should be taken into consideration when assessing Thomas's synthetic thought. Following the editors' introduction, thirteen scholarly contributions and an epilogue explore Aquinas's interaction with medieval canon law through four major themes: Dominican Matters; Foundations Matters of Faith, Truth, and Law; Moral Matters; and Sacramental Matters. Approximately half the contributors are specialists from the field of medieval canon law, and half are grounded in Thomistic tradition. The result is a unique and scholarly contribution to two major research areas that may open avenues for similar studies of other key figures in the scholastic tradition.
