Relational Ontology and Personhood in Joseph Ratzinger

Abstract Although contemporary scholarship has established the centrality of Christology, communion, and relational personhood in Joseph Ratzinger’s theological anthropology, little attention has been given to the ontological principle that unifies these themes. This article argues that the analogical grammar of participation provides the metaphysical foundation. Through analogy, the human person truly participates in the filial life of the Son without compromising the irreducible distinction between Creator and creature. The study demonstrates that creation, Christology, adoptive sonship, ecclesial communion, and eschatological fulfilment are not discrete theological loci but successive determinations of a single participatory ontology. Analogy, therefore, functions as the ontological grammar governing the transition from Ratzinger’s Trinitarian and Christological theology to theological anthropology.By establishing this analogical framework as the governing principle of Ratzinger’s anthropology, the article offers a fresh interpretation of his thought and contributes to contemporary debates on relational ontology, participation, and the theological foundations of human personhood.
