The author traces an interesting development in Jean-Luc Marion’s thought, from explicit rejection of Karl Rahner’s thought to strong affinities with it. Marion’s early theology aligns itself with Hans Urs von Balthasar’s, making a later turn to Rahner seem impossible. But in his phenomenological trilogy and newer theological reflections, Marion opens to a Rahnerian perspective, particularly with respect to the mutual collaboration of faith and reason. Marion thus provides one more example of Rahner’s enduring significance.
