It is well known that Henri de Lubac's groundbreaking and highly controversial work on nature and grace had important implications for the Church's relationship to culture and was intended to remove a philosophical obstacle hindering Catholicism's faithful engagement with the secular world. This book addresses a too-often neglected dimension of de Lubac's theological renewal by examining the centrality and indispensability of spiritual exegesis in his oeuvre and making explicit its social and political significance for the Church's worship and witness. In addition to exploring the historical and ecclesial context within which he worked, the current work brings de Lubac into a critical engagement with the more recent theological movements of postliberalism and radical orthodoxy in order to demonstrate the enduring significance of his theological vision.
