Thomas Aquinas (1224–1274) is one of the most important thinkers in the history of western civilization. A philosopher and theologian, a priest and preacher, Aquinas bequeathed to the world an enduring synthesis of philosophy, theology, and Christian spirituality. Aquinas championed the integration of faith and action, sound doctrine and right living, orthodoxy and orthopraxy. From the thirteenth century through the present day, his legacy has served as a blessing for the church and beyond. In the nearly eight hundred years since Aquinas’s death, his thought has been studied, interpreted, criticized, reinvigorated, and anointed as the exemplar of Catholic theology. Thomas and the Thomists, a new volume in the Mapping the Tradition series, serves as an introduction to the life of Aquinas, the major contours of his teaching, and the lasting contribution he made to Christian thought. Romanus Cessario and Cajetan Cuddy also outline the history of the Thomist tradition—the great school of Aquinas’s interpreters—from the medieval era through the revival of the Thomist heritage in the nineteenth and twentieth centuries. This volume affords its readers a working guide to understanding the history of Aquinas and his expositors as well as to grasping their significance for us today.
