Toward an East–West Ultramontane Polyphony: On Dogma, Ecclesial Unity, and the Filioque

Toward an East–West Ultramontane Polyphony:On Dogma, Ecclesial Unity, and the Filioque Thomas Joseph White O.P. The book that the contributors to this symposium have commented upon with graciousness and remarkable intellectual acuity is a work consisting of four parts. There are four main claims to the book associated with these four parts, each of which is divided into sub-themes. Thus, one can denote a number of inevitably controversial ideas advanced by the book. In clarifying the nature of these claims, I can initially respond to some of the main points advanced by various of the helpful review essays in this symposium. Framing the Argument of the Book The first part of the work posits that there is a fundamental developmental continuity between Old and New Testament revelation, wherein God is revealed first to Israel as the one Creator, and subsequently in Jesus Christ as three distinct persons, the eternal Father, Son, and Holy Spirit.1 This revelation is in turn received in the pre-Nicene era of the early Church, principally under a twofold conceptual format, according firstly to a model of God as a single transcendent subject of wisdom who sends his Word into the world in human nature, and inspires the prophets by his Spirit (the apologists' monotheistic model, exemplified by Justin Martyr) and, secondly, to End Page 569 a model of economic Trinitarian activity, of the Father, Son and Spirit, who are each divine and one in being, active in sacred history (Irenaeus).2 Nicene Trinitarian authors sought in various ways to find a deeper concordance of the two approaches, one of which emphasized more the immanent unity of God (potentially tending toward a danger of Sabellianism) and the other of which emphasized real distinction of persons active in the economy (potentially tending toward the danger of subordinationism).3 Pro-Nicene figures like Athanasius, Gregory of Nazianzus, and Augustine, among others, paved the way for a mature doctrine of immanent Trinitarian life, in which God was understood to be characterized, mysteriously, by eternal processions of the Word and the Spirit who originate from the Father, and receive from him the plenitude of their deity or divine nature, and thus are equally and identically the one God.4 God is mysteriously three persons who are truly one both in essence and being. The second part of the book is concerned with the theological exploration of what it means to speak of God as one, and of the divine nature of God. This determination of Christian theological wisdom stems from a threefold exigency: first, to uncover the inner unity of revelation itself, as indeed the Israelite revelation of the divine unity and the oneness of God the transcendent Creator is thematic to both Testaments;5 second, to consider the preconditions of Nicene orthodoxy, as indeed the claim that the three persons in God are one in essence or nature presupposes that there is a nature of God that is one common to the three persons;6 third, to consider what must be said about the inner life of God as truth and love, as a precondition for thinking about the processional life of the Word and Spirit, who are immanent distinct persons in God who receive and possess this fullness of life but who do not divide this one eternal life in God or cause it to evolve due to their relational proceeding.7 I argue that a consideration of God's nature as simple, perfect, good, eternal, immutable, and so forth is essential to any theology that takes the biblical revelation of the unity and transcendence of God seriously, and therefore confesses the revelation of the Trinity integrally.8 Furthermore, regarding End Page 570 the apophatic contours of this form of reflection, I hold that it is precisely in order to guarantee the kind of circumspect avoidance of "non-biblical speculation" about positive knowledge of God outside of Christ that it is necessary to qualify rightly how God is not identifiable with creation and thus remains unknown in his inner divine nature and eternal life apart from and outside of his divine self-disclosure in the revelation of the Old and New Testaments.
