Alius in alio, quia non aliud in utroque: Unity as the distinguishing mark of Trinitarian relational theo-ontology

Review of "Unity: Metaphysics, theology, cosmology” (Città Nuova, 2022)

Abstract

The guiding principle that transpires from the three essays of Massimo Donà, Piero Coda and Carmelo Meazza starts from the divine unity, affirmed fundamentally in the language of relationship. The Trinity is the «One that is distinct» (K. Hemmerle). Such unitas Trinitatis constitutes the arx omnis unitatis. The economic gesture manifests this distinction and self-giving of the divine unity as agape that gives itself and “alienates” itself. It is precisely this self-alienation that enables the unity between Creator and creature.
