... Henri de Lubac’s most important contribution to Catholic theology was a sustained analysis of the relation between nature and grace. In the 1930s he argued that standard theologies of the neoscholastic tradition used a metaphysically rigid, dualistic account of human destiny that ironically confirmed rather than overcame the modern suspicion that our everyday lives and concerns (nature) have no intrinsic contact with or need for the life of faith (grace). Instead of overcoming the dualisms that have tended to drive modern thought and life toward contrastive and fruitless antinomies, neoscholasticism unwittingly absorbed the tendency into itself.
When de Lubac claimed that the fundamental structure of neoscholasticism was a covert form of modernism, he was making a direct attack on the modes of theology that dominated the Church in the first half of the twentieth century. Not surprisingly, he became a suspect character in the eyes of church authorities. In the 1950s he was silenced by his superiors in the Society of Jesus.
One would think that, as a result, de Lubac would have embraced the spirit of innovation that flourished after Vatican II. He did not. Near the end of his life he wrote a small and bitter book, A Brief Catechesis on Nature and Grace. In its pages he sought to address what he regarded as a fundamental misunderstanding of his basic insights, and its main thrust is a defense of the core theological judgments of the neoscholastic tradition he spent his life criticizing.
The message is clear: Readers cannot understand Henri de Lubac’s theology of nature and grace unless they know and accept the basic outlines of classical Thomistic theology. Thus the paradox, once again. By the 1980s, Henri de Lubac, the great critic of dry and dusty neoscholasticism, saw that the younger generation needed to be catechized into the standard, baseline commitments of Catholic theology. Ressourcement does not work if students have neither context nor framework in which to place the richness and depth of the tradition.
