On Theology as the Act of the Word and the Spirit
Quaeritur
Utrum theologia non sit sermo humanus aliis superior, sed ipsa actio Verbi et Spiritus, in qua et per quam omnis loquela theologica habet esse suum—ita ut verbum fidei non solum de Deo loquatur, sed in ipso Dei loquendo subsistat.
Whether theology is not a human discourse standing above others but the living act of the Word and the Spirit, within and through which all theological speech receives its being—such that the word of faith does not merely speak about God, but subsists within God’s own act of speaking.
Thesis
Theology is the continuing act of divine self-communication in language. The Word is its content and the Spirit its cause. Human discourse participates in this act finitely, not by nature but by grace. Thus, theology speaks truly only as it becomes the act of the Word through the causality of the Spirit, the infinite in the finite.
Locus classicus
“When the Spirit of truth comes, he will guide you into all the truth; for he will not speak on his own, but will speak whatever he hears.”
— John 16:13
This verse establishes the pneumatological condition of all theological truth. The Spirit’s speech is not autonomous but participatory. The Spirit speaks what it hears from the Word, mediating the eternal discourse of the Son within the languages of history. Theology thus lives as the finite echo of an infinite conversation between Word and Spirit.
Explicatio
In human sciences, language and meaning are related externally: propositions describe or directly denote states of affairs. In theology, language and being coincide in the divine act. The Word is the ratio essendi of both creation and signification. The Spirit, as the divine causal medium, renders finite discourse proportionate to infinite meaning, linking felicity (authorized saying) with truth (ontological correspondence).
Let us formalize the relation as an analogy between divine and human discourse:
Let L∞ denote the eternal Word, the infinite language of divine self-communication.
Let Lₜ denote finite theological discourse, the language of faith and confession.
Let Auth(Lₜ) denote the authorization of Lₜ by the Spirit.
Then, theological truth obtains only if Auth(Lₜ) → (Lₜ ⊂ L∞); that is, finite discourse is true insofar as the Spirit causes its participation in the divine Word.
This causality is non-competitive. Human language remains finite and historical, yet within it the Spirit effects ontological reference. The Word speaks through words. Accordingly, the infinite inhabits the finite without destroying it. Theology is precisely this indwelling speech; it is an act in which divine causality and human signification coincide.
Objectiones
Obiectio I. Kantian Transcendentalism limits cognition to phenomena structured by the categories of understanding. Theology, as human reflection, can express moral faith but not divine causation within thought or speech. To say that theology is an act of Word and Spirit is to mistake moral symbolism for metaphysical participation, violating the autonomy of reason and the bounds of possible experience.
Obiectio II. Barthian Revelationism insists that revelation is the wholly other act of God, never a human process. Theology may witness to the Word but is not itself the Word’s act. To identify theology with the act of Word and Spirit is to blur the infinite qualitative distinction between Creator and creature, turning divine revelation into a form of human religiosity.
Obiectio III. Wittgensteinian linguistic conventionalism teaches that meaning arises from the use of language within forms of life (Lebensform). Theological felicity, then, is determined by ecclesial grammar, not metaphysical causation. To posit the Spirit as the cause of meaning introduces a category mistake,for causes belong to physics, not to language. The Spirit’s “authorization” adds nothing to grammatical propriety.
Obiectio IV. In Hegelian idealism, Spirit realizes itself through human consciousness and divine speech is the dialectical unfolding of Absolute knowing. Theology, therefore, is not a separate act of Word and Spirit but the self-comprehension of Spirit in finite reason. To posit transcendent divine causality within theology is to regress to pre-critical representationalism.
Obiectio V. Within post-liberal theology, theology’s truth is intralinguistic: it is coherence within the Church’s rule of faith. Divine causation is a superfluous hypothesis. Any claim that the Spirit determines what is in or out of T, or that the Word speaks through language, replaces theological humility with metaphysical presumption.
Responsiones
Ad I. Kant’s boundaries define reason’s autonomy, not God’s. Revelation does not transgress the categories of understanding but fulfills them by constituting their very possibility. The Spirit does not add a second cause to human thought but founds its capacity to signify God. Theological cognition is thus not heteronomous but participatory: reason becomes itself when moved by the Spirit to speak truthfully of the Word.
Ad II. Barth’s distinction between revelation and theology guards divine freedom but misconceives the Spirit’s immanence. Theology is not revelation itself but its continuation within the economy of language. The Word once spoken in Christ continues to act in the Church through the Spirit. The Spirit’s causality ensures that theology’s human speech remains the site of divine self-communication, not its substitute.
Ad III. Wittgenstein is right that meaning depends on use, but theological use presupposes a deeper authorization. The Church’s grammar exists because the Spirit constitutes it. Felicity, in theology, is not mere conformity to rules but participation in divine life. The Spirit’s causality is not empirical but constitutive. He makes possible the very relation between finite sign and infinite referent.
Without the Spirit, theological grammar collapses into tautology; with the Spirit, it becomes the living speech of God.
Ad IV. Hegel’s dialectic recognizes the unity of thought and being but confuses participation with identity. The Spirit in theology is not the world’s consciousness of itself but God’s causal presence within finite language. The divine Word does not evolve into human understanding; it speaks through it. Theology is not Spirit’s self-mediation but Spirit’s indwelling of the finite as grace.
The difference between divine and human remains, yet it is precisely in this difference that communion occurs.
Ad V. Post-liberal coherence explains theology’s internal structure but cannot account for its truth. Felicity within the community (FT) requires linkage to truth-conditions (TC) that obtain in divine reality. That link is the Spirit’s causality. The Word guarantees referential content; the Spirit guarantees participation. Thus, theology is neither self-referential grammar nor speculative metaphysics but a dual act: the Word speaking, the Spirit authorizing.
Theological meaning is therefore realist because it is caused.
Nota
To speak of theology as the act of Word and Spirit is to confess that all true theology is God’s own discourse in the mode of the finite.
The Holy Spirit determines inclusion within T (the formal language of theology) and mediates the causal link between felicity and truth.
The Word provides the ontological content of that truth; the Spirit provides its efficacious form.
Hence: FT + TC = Truth of Theological Speech where FT (felicity conditions) ensure internal coherence and authorization, and TC (truth conditions) denote the real divine states of affairs modeled ontologically by T. The Spirit, as both formal and causal principle, unites these two in a single act of divine communication.
Determinatio
From the foregoing it is determined that:
Theology is not autonomous discourse but the continuing act of the divine Word communicated through the Spirit.
The Spirit’s causality is non-competitive and constitutive: it authorizes human language to bear divine truth.
The Word’s eternity is the meta-language within which all finite theological languages (Lₙ) are interpreted and fulfilled.
Truth in theology arises when the felicity of human speech (authorization within T) is linked, by the Spirit, to real states of divine being modeled in ontology.
The nova lingua theologiae is therefore incarnational: the infinite speaks within the finite, and the finite becomes transparent to the infinite.
In this union, theology ceases to be mere talk about God and becomes God’s own speaking through the creature. Theology is thus the act of Word and Spirit, an event of truth in which language itself becomes participation in divine life.
Transitus ad Disputationem XXI
In the foregoing disputation it was affirmed that theology is not merely a reflective discourse about divine realities but the very event of divine speech, the actus Verbi et Spiritus in which God addresses the world through human language. The theologian, in speaking truly, does not stand before the Word as observer but is caught up within the living exchange between Word and Spirit. Theology thus appeared as participation in a trinitarian act rather than the exercise of a solitary intellect.
Yet this very insight now summons a further inquiry. If theology is the act of Word and Spirit, by what means are these two united and distinguished within the one speaking of God? How does the communicatio between Verbum and Spiritus ground the possibility of theological meaning, such that divine truth may be both given and received? And what does this communication imply for the structure of theological language itself, for its authority, its coherence, and its power to signify beyond itself?
Therefore we pass to Disputationem XXI: De Meta-Lingua Theologiae: De Communicatione Verbi et Spiritus, in which it will be examined how the divine Word and the Holy Spirit together constitute the meta-linguistic horizon of theology, the inner dialogue by which the infinite speaks itself into the finite and gathers finite speech into the eternal conversation of God.
