In this fourth volume of his
magnnum opus
, von Balthasar considers the metaphysical tradition of the contemplation of Being. He provides major studies of Homer, the Greek Tragedians, Plato and Plotinus and the development of this tradition in the Middle Ages. He then explores the analogy between the metaphysical vision of the Being and the Christian vision of the divine glory of the Trinity. The book is a remarkable attempt to rediscover the ancient vision of Being in all its awesomeness as the context within which the specifically Christian vision, rooted in God's gracious self-revelation, took form and was expressed.
