On the Hyperintensionality of Divine Action
Quaeritur
Utrum actus divini, quoad identitatem, formam, et rationem essendi, non possint explicari per extensionalem aequivalentiam, modalem necessitationem, vel possibilia mundorum, sed sint essentialiter hyperintensionales; et utrum veritas theologica requirat talem hyperintensionalitatem ut Deus cognoscatur secundum actum, non secundum eventum.
Whether the identity and form of divine acts can be explained by extensional equivalence, modal necessity, or possible-world semantics, or whether they are essentially hyperintensional; and whether theological truth requires such hyperintensionality so that God is known according to the act God performs, not merely according to an outcome.
Thesis
Divine acts are hyperintensional. By this we mean that the identity of a divine act cannot be captured by any framework in which acts are considered the same whenever they yield the same outcomes, share the same extension, or hold necessarily across all possible worlds. A divine act is not defined by its effects, nor by the set of circumstances under which it occurs, nor by its modal profile. Instead, a divine act is individuated by its formal identity within the Logos, by the specific constitutive act through which the Logos brings a res into being or presence, and by the Spirit’s concrete donation of that act to creatures.
Thus, extension does not capture divine identity,modal equivalence does not capture divine identity, and possible-world semantics is too coarse-grained to describe divine agency. A hyperintensional account alone preserves the theological conviction that God’s acts are personal, irreducible, and internally differentiated modes of the one divine life.
Locus Classicus
1. Exodus 3:14 — אֶהְיֶה אֲשֶׁר אֶהְיֶה
“I AM WHO I AM.”
This is not a definition, but an identity of act. Being itself is hyperintensional, for it names a unique form of divine acting, not a property instantiated across possible worlds.
2. John 5:19 — ἃ ἂν ἐκεῖνος ποιῇ, ταῦτα καὶ ὁ Υἱὸς ὁμοίως ποιεῖ
“Whatever the Father does, the Son does likewise.”
The divine act is not duplicated or numerically separable. Rather, its identity is internal to the Trinity, not extensionalized in effects.
3. Athanasius, Contra Arianos I.21
ὁμοούσιος οὐ κατὰ θέλησιν ἀλλὰ κατὰ φύσιν.
“Of one being not by will but by nature.”
The divine act is identical with divine being; it is an identity finer than any modal equivalence.
4. Gregory of Nyssa, Ad Ablabium
Οὐ τὰ γινόμενα, ἀλλ᾽ ὁ τρόπος τῆς ἐνεργείας τὴν διαφοράν ποιεῖ.
“It is not the outcomes, but the manner of operation that makes the distinction.”
This is a classical statement of hyperintensionality clearly stating that the manner by which something obtains profoundly matters.
5. Luther, WA 40/III, 343
“Deus non est causa sicut causae creatae.”
“God is not a cause as created causes are causes.”
Thus God cannot be modeled extensionally.
Explicatio
1. Why extensional identity is inadequate
Extensional identity holds when two expressions apply to precisely the same set of objects. If two predicates pick out exactly the same individuals, classical extensional logic treats them as equivalent. For example, if every creature that is forgiven is also elected, and every creature that is elected is also justified, then these predicates are extensionally equivalent: they have the same extension.
Formally, if for all x, x is forgiven ↔ x is elected and x is elected ↔ x is justified, then the predicates forgiven, elected, and justified are coextensive.
Similarly, in the Spirit’s work, if for all x, x speaks in the Spirit ↔ x has been given the Spirit, and x has been given the Spirit ↔ the Spirit dwells in x, then Spirit-speaking, Spirit-giving, and Spirit-indwelling are extensionally equivalent expressions.
But extensional equivalence tells us nothing about what distinguishes these divine actions in God Himself. Forgiving is not the same divine act as electing, nor is electing the same divine act as justifying. Likewise, the Spirit’s giving, indwelling, and speaking are not identical divine operations simply because they coincide in the believer. Extensional identity collapses formally distinct divine works into a single undifferentiated outcome and therefore cannot serve as the framework for a theology that seeks to speak truthfully of God’s own acting.
2. Why modal equivalence is insufficient
A second temptation is to appeal to modal identity. Accordingly, if two acts occur in every possible world in which God acts toward creatures, or if one cannot conceive God performing one without the other, then they are treated as identical.
Creation and preservation offer a clear example. Classical theology holds that God’s preserving of the creature is nothing other than the continued giving of being. Because no creature could exist for a moment apart from God’s sustaining act, creation and preservation are necessarily coextensive: wherever one occurs, the other is already taking place.
So too with incarnation and redemption. In the Christian confession, the Son becomes incarnate for our salvation, and His incarnate life is unintelligible apart from His redeeming work. One cannot separate them modally, for in every possible description of God’s salvific activity, incarnation and redemption occur together.
Yet modal inseparability does not entail formal identity. Creation and preservation differ in their reason, because one brings being into existence, while the other maintains that being in existence. Incarnation and redemption differ likewise, for one is the assumption of human nature, the other is the reconciling act performed in that nature. Modal equivalence cannot register these distinctions because it treats any necessarily co-occurring acts as identical, thereby losing the finer structure of God’s activity that theology must retain.
3. Why divine acts require hyperintensional individuation
If theology is to speak truthfully, it must be able to say why this particular divine act grounds this theological statement. In our broader account, a theological utterance is true because the Logos performs a determinate act—Λ ⊨* Tₜ. But determinate truth requires determinate action. If divine acts could not be distinguished except by their extensions or modal profiles, then the truthmaker for any theological statement would be some undifferentiated divine activity, and doctrinal distinctions would lose their ontological grounding.
By hyperintensional identity I mean that divine acts differ not by their outcomes or by their modal placement but by their internal form in the Logos—the determinate way God is acting here and not otherwise. This internal form cannot be captured by appeal to effects, extensions, or modal profiles; it belongs to the act as God performs it. Forgiving is formally distinct from electing because each expresses a different aspect of the divine life, even when the same creature receives both. The Spirit’s indwelling is formally distinct from the Spirit’s giving because each arises from a different manner of divine self-communication. Hyperintensionality preserves the integrity of these differences.The Spirit does not donate to creatures a general divine presence or a generic divine favor. Instead, the Spirit donates the specific act that God is performing toward the believer. In one moment, this may be forgiveness; in another, consolation; in another, empowerment. The specificity of the Spirit’s donation presupposes a finely articulated structure of divine action in God Himself. Without this specificity, divine presence would become conceptual rather than real, and theology would lose the concreteness of God’s address.
5. Felicity is indexed to particular divine acts
A theological assertion is felicitous only if it corresponds to the act God is performing here and now—an act that is already individuated in God with a hyperintensional precision. The Spirit authorizes not theological grammar in general but this particular word because this particular divine act is being given. Thus the intelligibility of theology depends on a hyperintensional account of divine acting.
Objectiones
Ob I: According to classical extensionalism if two divine acts produce the same effects, they are the same act. If this is so, there is o need for hyperintensional identity.
Ob II: Modal realism holds that if God necessarily performs A and B, then He performs A and B in all possible worlds, and thus A = B. Therefore, modal equivalence suffices in individuation.
Ob III: Thomism claims that since God is simple, all divine actions are identical and distinctions collapse.
Ob IV: Deflationism asserts that hyperintensionality describes linguistic distinction, not metaphysical difference.
Ob V: Postliberalism holds that since all distinctions arise from use within the community, divine action adds nothing.
Responsiones
Ad I: Effects underdetermine cause. Divine acts differ in their formal ratio, not merely in outcome (Gregory of Nyssa). Thus, extension collapses personal identity.
Ad II: Possible-world semantics assumes shared structure with creaturely action. But divine acts exist outside modal ontology; they ground modality rather than inhabit it. God is not a node in a modal structure but its creator.
Ad III: While implicity entails no composition in God, it does not follow that divine acts lack distinct formal identities. The Fathers held simplicity alongside real distinctions of operation.
Ad IV: Hyperintensionality is not linguistic fineness but metaphysical precision. Divine act identity is not a function of language but of participation in the Logos.
Ad V: While usage explains how we talk, it does not identify what God does. Without hyperintensional divine action, grammar loses its anchor in reality.
Nota
Hyperintensionality is the ontological form of God’s personal action. We have seen that constitutive causation (L) requires fine-grained identity; that real presence (LI) is specific, not generic; that donation (LII) concerns a particular res, and that felicity (LIII) authorizes a particular act of creaturely speech. If theological semantics were simply extensional or modal, the Trinity collapses into one role, the sacrament collapses into symbol, revelation collapses into a proposition, grace collapses into an effect, and Christology collapses into monism.
Regarding the Trinity, hyperintensionality preserves the distinction of the trinitarian persons, Christ’s unique acts, sacramental specificity, and the performative depth of divine truth. Simply put, hyperintensionality is not an analytic embellishment but a theological necessity. Without it, we could not preserve the conviction that God acts personally and decisively for the creature, nor could we maintain the integrity of the Gospel’s claim that God’s work is addressed to us in its fullness and specificity.
Determinatio
We have determined that:
-
Divine acts are intrinsically hyperintensional, distinct in their internal form even when extensionally identical.
-
Neither extensional equivalence nor modal necessity suffices to individuate divine action.
-
Hyperintensional identity flows from the Logos’ constitutive act (L) and is made present (LI), donated (LII), and authorized (LIII).
-
Theological truth (Λ ⊨* Tₜ) requires such hyperintensional grounding.
-
Therefore, theology must employ a hyperintensional semantics to speak truly of God.
Transitus ad Disputationem LV: De Intentione Divina et Identitate Actuum in Deo
Having established hyperintensionality in divine action, we proceed to the related question as to how divine intentions are related to divine acts, and how the Logos unifies them without collapsing distinctions.
Thus, we turn to Disputatio LV: De Intentione Divina: Utrum Intentiones Dei Sint Actus et Quomodo Unitas in Logō Constituitur, where we shall inquire as to whether God’s intentions are identical with His acts, and how the Logos grounds their unity and distinction.
