Trinitarian Confusions between East and West?

Richard Cross has argued that the East and West do not really "adopt radically divergent accounts of the Trinity" (Richard Cross, "Two Models of the Trinity," HeyJ XLIII (2002) 275-294). I believe Cross is fundamentally correct, though I do have some observations.

It is often claimed that the Eastern view (following the Cappadocian Fathers) starts from the diversity of the persons and then moves to account for the unity of the essence, while the Western view (following Augustine) starts from the unity of the divine essence and then attempts to account for the diversity of the persons. Clearly, much has been made of this distinction in the secondary literature. One finds characterizations of the difference between East and West such as the following: The Thomistic tradition originating in Augustine assumes this order of logical priority: Relation, Person, and the Processions; the Cappodocian tradition understands the logical priority this way: Processions, Person, the Relations. (e.g., See Knuuttila & Saarinen, "Innertrinitarishe Theologie in der Scholastik und bei Luther, " pp. 243-264, Caritas Dei: Beitraege zum Verstaendnis Luthers und der gegenwaertigen Oekumene.) Cross argues persuasively that the difference between the Eastern and Western traditions has little to do with theology, but everything to do with different philosophical assumptions operating in the East and West. "The Eastern view does, and the Western view does not, generally accept a sense in which the divine essence is a shared universal" (275). Gregory of Nyssa, for instance, claims that the divine essence is a singular multiply-instantiatable universal; Augustine denies this.

Cross begins his analysis by giving the standard metaphysical options on universals and particulars. He first distinguishes the substrate/property view of the constitution of substance from that of a congeries of properties having what Russell called "compresence." Secondly, he distinguishes properties as particulars from properties as universals. Accordingly, if properties are particulars, then the indiscernible properties of numerically distinct substances are themselves numerically distinct. However, if properties are universals, then the indiscernible properties of numerically distinct substances are identical (and thus by Leibniz's law) the same property. If two particulars have the same shade of blue and if these shades of blue are particulars - - one shade of blue is exactly like the other - - , then the shades of blue are numerically diverse. However, if the two particulars have the same shade of blue and the shades of blue are literally the same shade, then the blue is a universal. A universal is, by definition, a property that can be a constituent in more than one substance. Particular properties, by definition, cannot be constituents in more than one substance. Accordingly, the only real metaphysical possibility for overlapping substances on a bundle theory (the view that a substance is a compresence of properties) is that there are universal properties that are ingredient in each and every compresence.

This insight is crucial for understanding the putative divergence between the Eastern and Western views. For purposes of analysis, allow 'substance', 'hypostasis' and 'person' to be used interchangeably, and futher assume that 'divine essence' is an overlapping property (a property common to the three substances), and must thus be, on the previous analyis, a universal. This divine essence is termed the 'ousia' by the East. As to the question of whether this divine essence is one simple universal property, or a bundle of such properties, Cross follows Augustine: "God however is indeed called in multiple ways great, good, wise, blessed, true and anything else that seems not to be unworthy of him; but his greatness is identical with his wisdom . . . and his goodness is identical with his wisdom and greatness, and his truth is identical with them all; and with him being blessed is not one thing, and being great or wise or true or good, or just simply being (esse), another" (Trin. 6.7.8 CCSI., I, 237).

Gregory of Nyssa clearly articulates the view that the universal divine essene (ousia) is a unviversal that is multiply instantiated in the three divine persons:

"If now of two or more who are [man] in the same way, like Paul and Silas and Timothy an account of the ousia of men is sought, one will not give on account of the ousia of Paul, another one of Silas andd again another one of Timothy; but by whatever terms the ousia of Paul is shown, these same will fit the others as well. And those are homoousioi to each other, who are described by the same fomular of being" ("Human Nature in Gregy of Nyssa: Philosophical Background and Theological Singnificance," Supplements to Vigilae Christianae, 46, p. 709, p. 70).

The universal which is the divine essence is clearly numerically singular:

"But the nature is one, united to itself and a precisely undivided unit (monas), not increased through addition, not decreased through subtraction, but being and remaining one (even if it were to appear in a multitude), undivided, continuous, perfect, and not divided by the individuals who participate in it" (Gregory, Abl. GNO, III/I, 40.24-41.7).

Cross points out, however, that Gregory's universal is not ante rem. The divine essence does not exist uninstantiated, but is rather immanent in the persons; it is that "of which" the persons are (Cross, 281). The divine essence is shared by the persons, but the divine persons as overlapping bundles of properties do not share their own personal properties.

According to Cross, the Western theologians implicitly accept the view of the shareability of the divine essence by the persons even though they explicitly criticize this position. The western theologians deny that the divine essence is a universal "in the sense of 'universal' accepted by the West, not the sense accepted by the East" (Cross, 281). Though they deny this, they accept that the essence is shared by the persons. Augustine writes:

"In the simple Trinity one is as much as three are together, and two are not more than one, and in themselves they are infinite. So they are each in each and all in each, and each in all and all in all, and all are one" (Trin. 6.10.12, CCSL, L, 243).

Over eight centuries later, Aquinas echoes Augustine:

"In God, the essence is really identical with a [viz., each] person, even though the persons are really distinct from each other" (ST 1.39.1, c).

Yet the western theologians explicitly reject Nyssa's view on universals. Quoting Augustine again:

"If essence is species, like man, and those which we call substances or persons are three, then they have the same species in common, as Abraham, Isaac, and Jacob have in common the species which is called 'man'; and if while man can be subdivided into Abraham, Isaac, and Jacob, it does not mean that one man can be subdivided into several single men - - obviously he cannot, because one man is already a single man - - then how can one essence be subdivided into three substances or persons? For if essence, like man, is a species, then one essence is like one man" (Trin. 7.6.11, CSSL, L, 236).

Augustine's criticism assumes that if the divine essence is a species, and if a species is divisible, then the divine essence is divisible. But since this cannot be so, he concludes that the divine essence is not a species. But if it is not a species, then it is not a universal at all. Cross believes that Augustine holds that a universal (species) is divisible because he assumes that Neoplatonic notion of in re universals. Neoplatonists are nominalists here; they claim that universals (species) are merely aggregates of particulars.

Although Aquinas is not a Neoplatonic nominalist, his Aristotelian realism agrees on this point: "No universal is numerically the same in the things beneath it" (Scriptum super Libros Sententiarum 1.19.4.2). Cross concludes: "Unlike the Eastern tradition, . . . the Western tradition accepts - - as a matter of philosophical fact - - that universals, even in re universals, are not such that they are numerically identical in each exemplification" (Cross, 284). Thus, while the Cappadocians assumed that all universals, not just the divine essence, "are numerically singular, and . . . the particulars are collections of such universals" the Western tradition rejected the claim of the numerical singularity of universals and the consitution of particulars from universals (ibid.). While both the East and the West claimed that the divine essence is a singular property formed by the intersection of the properties of the persons, the West disagreed with the East in claiming that this intersection could be accounted for by claiming the existence of a numerically identical universal. The divine essence as a universal in re is not logically or metaphysically prior to the persons, but dependent and posterior to the persons. Yet, this essence is something more than its instantiations in the persons; for this essence is what makes possible the identity of these persons.

To the objection that Eastern and Western views must be theologically distinct because social trinitarian views can be grounded in the former and not via the latter, Cross claims that such views actually cannot be grounded in one tradition more properly than the other. It is just not the case that the Western view adopts a Trinity of subsistent relations between persons disallowing a social trinitarian approach, and the East a theory of personal processions completely compatible with a robust social trinitarianism.

The Western notion of subsistent relations claims that the persons are individuated with respect to dyadic relations holding between the persons. These dyadic relations are not constitutive of the persons themselves; they do not inhere in things, but somehow "hang between" their relata. Aquinas writes:

"Distinction in God arieses only through relations of origin . . . But a relation in God is not like an accident inherent in a subject, but is the divine essence itself. So it is subsistent just as the divine essence is subsistent. Just as, therefore, the Godhead is God, so the divine paternity is God the Father, who is a divine person. Therefore 'divine persons' signifies a relation as subsistent" (ST 1.28.1, c).

Cross points to Augustine as the source of this view, for it was Augustine who denied that God can be a subject for accidents, and thus rejecting accidents, identifies relations as the non-inherent "things" whose distinction does not entail a distinction in substance: "What is stated relationally does not designate substance. So although begotten differs from unbegotten, it does not indicate a different substance" (Trin. 5.5.6, CCSL., I, 210). Because accidents require a substrate, and because the presence of a substrate is incompatible with simplicity, the assertion of simplicity requires a denial of accidental personal properties. However, "a divine person can include a relation without that relation thereby entailing composition" (287). Thus, for the West, the divine persons cannot be pyschological subjects, for such psychological subjects are necessarily individuated by their non-relational properties.

Cross believes that Gregory of Nyssa effectively also embraced the category of subsistent relations. In the following quote, the distinguishing features of the persons are clearly the causal relations they possess with respect to each other:

"While confessing that the nature is undifferentiated, we do not deny a distinction in causality, by which alone we seize the distinction of the one from the other: that is, by believing that one is the cuse and the other is from the cause. There is the one which depends on the first, and there is that one which is through that which depends on the first" (Abl. GNO, III/I, 55.24 - 56.6).

So, as it turns out, the East is close to a doctrine of subsistent relations, and the West assumes that the divine essence is shareable among the three persons. Accordingly, both East and West deny social trinitarian accounts which hold the three persons as distinct pyschological subjects. While Eastern and Western views are consistent with social accounts of the Trinity - - a shareable divine essence among persons clearly allows for pyschologically distinct subjects - - both reject those accounts because of the need to individuate persons on the basis of something other than the accidental (non-relational) properties of the persons (Cross, 288).

What is to be said of this analysis? Clearly Cross has clarified matters greatly. That God is one and three, does seem to entail that the divine essence can be shared by persons. The Western view, that this essence is a numerically singular property shared by the persons, is not at all incompatible with the Eastern view that this essence is a universal that, while it is immanent in the persons, is none the less numerically one and multiply instantiatable in them. If this is so, then the unity from which the West begins is just the shareable property/universal. While the West might ground their talk of personal diversity upon the ground of divine unity, the shareable property of divine unity is nontheless dependent upon the bundled properties constituting the persons. Alternately, while the East might ground their talk of divine unity upon the grounds personal distinctiveness, this unity clearly, like the West, remains dependent upon the existence of the persons.

Cross's analysis, if true, suggests that while the Eastern and Western views have their own metaphysical models, each satisfies the same set of theological propositions. If this is so, then there is no theological differences between the two.

Luther and Ontology I

Metaphysics was clearly a going concern in the late Middle Ages. There was controversy of many kinds related, of course, to issues within medieval semantics. The common belief was that there must be a most general structure of the world presupposed by the categories within language itself. Important questions included the following: What is the nature of wholes and how are they related to parts (mereology)? What is the nature, and ontological status, of relations? How do essence and existence relate (especially within divine reality), and what ontological status does each have? Are there such things as universals, and, if so, in what do they consist? What is being in its most general nature? Is it univocal? Finally, and most importantly, what is the being of God? What does it mean to say that the divine has properties? Are these traditional divine properties compatible?

It would be odd to think that Luther burst on the scene in the early sixteenth century with a sophisticated theological vocabulary and theory that profoundly addressed the human existential situation and yet somehow circumvented (and was hence disconnected from) the traditional metaphysical problems. Unfortunately, although this would be odd, it is exactly what much post-Kantian Luther interpretation has seemed to assume. It has presupposed that the really interesting questions within Luther scholarship are questions as to how Luther's theological language connects to human existence lived coram deo and within the reality of God's promise. That this is important for Luther goes without saying. He did stress the power of the living Word, and emphasized what might be called the "performative" characteristics of language of the divine.

However, Luther always assumed that theological language has truth conditions, that propositions are true or false in so far as the state what is, or what is not, the case. Theological language is constative, not merely performative. God, for Luther, is really triune; there actually are two disconsonant natures within Christ; the physical Body of Christ is really present in the bread and wine at the communion table. The infinite really is somehow in the finite in such a way that the infinite remains infinite while the finite remains finite. What is more, Christ really is present in the Christian such that one can speak of "ein Kuchen." As is the case in the history of theology generally, there is a "unity" or "identity in difference" presupposed within key theological loci. While Luther understood that the assertion of the existence of such identities was justified finally on the basis of revelation, he did not skrink away from calling such such assertions true, and supposing that they are true because they state some state of affairs that actually obtains.

The question is how to conceive these identities. Clearly, Luther believed that Aristotle was a great enemy to theology, and much preferred Plato to his even more precocious student. But what metaphysics is presupposed if the substance/accident metaphysics of Aristotle is incapable of conceiving the res ineffabilis of the two natures of Christ or the three persons of the Trinity? Should one simply assume that there is no way things ultimately stand that make true dogmatic theological propositions? Would one be better off construing dogmatic theological propositions relationally, that is, as expressing or specifying human experience in relation to divine reality. If Kant is right, of course, theological expressions must finally be construed as being about human experience (thinking, feeling, or doing), and about the phenomena of "limit points" within that experience. If Kant is right, then the truth of theological expressions, for Luther, simply can't be determined by objectively existing states of affairs.

But, I would argue, Kant is precisely wrong as an interpreter of Luther. Luther must be understood within his context as an Augustinian trained in the nominalist tradition, an Augustinian knowing standard nominalist semantic theory and metaphysics, an Augustinian who, however, is so moved by the incomprehensibility and ultimate significance of the res ineffabilis that he is willing to be innovative both semantically and metaphysically. About this, I shall have much more to say in subsequent posts.
