In the twenty-five years since his death, Karl Rahner moved from being the most celebrated Roman Catholic theologian of the twentieth century to among the most neglected of the twenty-first. This work attempts to redress this imbalance, with the contributors treating all the major themes and legacies of his theology. Rahner emerges from this collection as a paragon of a theology which is never insular or inward-looking but is always bold and innovative in its engagement with the range of questions with which contemporary theology is ineluctably confronted by our twenty-first-century world.
