Аннотация:This chapter considers the nature and genesis of the ressourcement movement and argues that its leading exponents inspired a renaissance in twentieth‐century Catholic theology that culminated in the reforms of Vatican II. It attempts to shed light on the complex question of terminology, the interpretation of which still engenders controversy in analyses of ressourcement and nouvelle théologie. It offers insights into the role of ressourcement theologians in the struggle against Nazism and asserts that the movement possesses an enduring relevance for the Christian churches and for modern society.
