Relying on both Chenu's previously unpublished materials and his many publications, Christophe Potworowski examines the role of faith and contemplation in the Dominican life and in theology as well as considering the historical and social dimensions of the human situation in terms of individual and ecclesial existence. He discusses the prophetic role of the theologian and some of the problems this involves. Potworowski raises the question of how incarnation as an overall structure is related to the particularities of Christology and provides insights into the development of Catholic theology in the crucial period leading to Vatican II. The accompanying bibliography of Chenu's complete writings, unavailable elsewhere, is a valuable instrument of theological research.
