The ‘question of Being’ is in a sense deeply against the spirit of the age since the rise of hermeneutics has substantially led to the eclipse of a traditional metaphysics of the self and the world. The central role of ontology in the thought of Hans Urs von Balthasar therefore makes him appear as a figure who is deeply against the grain of much current thinking, and who stands as a bulwark in defence of traditional, or classical, perspectives.

We can trace two primary sources for the role of Being in von Balthasar’s theology. The first is Martin Heidegger, whose vocabulary of Seinsvergessenheit (‘forgetfulness of Being’) sounds throughout von Balthasar’s discussions of Being. The very centrality of Being and of the Ontological Difference (which von Balthasar reads as a thomistic real distinction), is a sign of von Balthasar’s debt to the German philosopher, even if he proves highly critical of many aspects of the heideggerian project in its particularity.’ By far the more important influence is that of Thomas Aquinas, who is discussed in a section from the fourth volume of the English translation (The Realm of Metaphysics in Antiquity) and again in the fifth (The Realm of Metaphysics in the Modem Age). According to von Balthasar, ‘what Thomas does is to use beauty to define being’. This is a resonant statement indeed, since, to a not inconsiderable extent, it holds also for von Balthasar himself and the whole of his Herrlichkeit project. Time and again during these central volumes, von Balthasar will return to the theme of Being as that which governs the most fundamental aspects of aesthetics, philosophy and theology, as well as the understanding of the human and the grounding of human experience.
