Saint Thomas Aquinas showed the world that Catholic theology is not just something meant to stimulate the mind. Indeed, the authentic study of the sacra doctrina exercises a shaping influence on the whole of the Christian life. In this volume, Dominican theologian Father Romanus Cessario, OP, follows this precedent by considering the integration of theology and Christian living. Focusing on various aspects of Catholic theology and spirituality, the essays in this volume explore the essential relationship between truth and grace. With characteristic wisdom and insight, Father Cessario reveals how theology and sanctity share a common origin and end. Here the doctrine of Saint Thomas Aquinas and his exponents emerges as something eminently relevant to Christian living in the twenty-first century. Written for all those who take the theological life seriously, Theology and Sanctity explains how - and why - only the truth has grace. Catejan Cuddy's introduction and chapter headnotes reveal the essays' common threads while highlighting their broader contributions to Catholic theology.
