This is a collection of articles written over the space of twenty years on various subjects connected to the rationality of faith and its presentation in the contemporary world. Marion discusses the role of the intellectual in the church, the rationality of faith, the infinite worth and incomprehensibility of the human, the phenomenality of the sacraments, and the phenomenological nature of miracles and of revelation more broadly. Throughout he stresses that faith has its own rationality, which is one of love, gift, and givenness, which can be outlined phenomenologically and hence expressed with philosophical rigor. He also criticizes various movements within Catholicism to intellectualize the role of the laity and instead argues for the simple responsibility of the baptized as church of Christ in need of the sacraments and unfolding their particular rigor and “logic.” Marion outlines the gift-character of faith and sacraments and their essential phenomenality of giveness, which calls forth a response of love and devotion in the sense of kenotic abandon. He ends with an analysis of sanctity.
