Abstract

These reflections will, firstly, propose a philosophical solution to the Trinitarian problem of the “three-in-one,” and secondly, show how love is foundational to the divine being. Beginning with the Aristotelian notion of substance, I will show how substance undergoes a first modification in the consideration that substance finds its fullest realization in a person existing in a love-relation with another person. The highest instance of this, in turn, will prove to be found in persons whose very essences are constituted by such relationality and the communion resulting from it. This will force a second modification of substance: the unity of substance will turn out to have its highest instance in the moral unity of a plurality of persons existing in love—which leads to the solution of the “three-in-one” problem. I will end by reflecting on the foundational role of love with respect to absolute being.
