Abstract
Maurice Blondel’s philosophy has had a decisive influence on the theology of Henri de Lubac, but more than an influence, it goes of an encounter and a dialogue between two great Catholic thinkers. This article proposes, over the course of successive encounters and collaborations between Blondel and Lubac, a presentation of Lubac’s reflection in that it extends Blondel’s critique of extrinsicity to the field of theology. This friendship between Lubac and Blondel testifies to the inherent character of the mystical question to both philosophy and theology. This anchoring signifies the Mystery of Christ at work in the gesture of reason and in the understanding of faith. At the same time, Lubac promotes, in philosophy itself, an intelligence through faith. Friendship has not been an empty word with Lubac who openly defended Maurice Blondel on several occasions, and even after Blondel’s death, when Lubac continued to make the philosopher’s thought known by publishing and annotating a large part of his correspondence.
