BLONDEL, MODERN CATHOLIC THEOLOGY AND THE LEIBNIZIAN EUCHARISTIC BOND

The category of substance is fundamental in Leibniz's philosophy, and conceived in specifically theological terms in his late correspondence with Bartholomaeus des Bosses. The exchange develops as a discussion of the bond of substance ( vinculum substantiale ) in the transubstantiated eucharistic host, but the bond also provides the basis for a general theory of universal substance. This eucharistic vision of the substance of the world is appropriated by Maurice Blondel as the basis of his philosophy of action, in which divine transforming activity is necessarily implied, and which he describes as a form of transubstantiation of both the subject of action and its material object. This Leibnizian-Blondelian theology of the divine transformation of the substance of the world provides eucharistic foundations for modern Catholic social teaching.
