This essay arises from the work of the Department of Philosophical Theology at ILT’s Christ School of Theology, where the central task is to clarify the conditions for the possibility of theological meaning, intelligibility, and truth in a post-Christendom context.
The question of theological meaning can no longer be approached as though its conditions were secure. The difficulty is not first that theological claims are disputed, nor that their truth is contested, but that what it would mean for such claims to mean at all has become unclear. The language of God, grace, redemption, and divine action continues to be employed, yet the relation between this language and any domain to which it might answer has been fundamentally destabilized.
This instability is not unique to theology. It arises wherever theoretical discourse is pressed to clarify the relation between its formal structure and the reality it purports to describe. A theory may be syntactically well-formed, inferentially rich, and pragmatically effective while remaining semantically indeterminate unless interpreted. Syntax alone does not yield reference. Nor does disciplined use by itself secure truth. The question is therefore unavoidable: what must be the case for a theory to be about anything at all?
Once this question is posed, the classical opposition between realism and its rivals must be reformulated with greater precision. The issue is not simply whether one affirms or denies the reality of a domain, but how the quantificational structure of a theory is to be understood with respect to that domain. Realism affirms that the entities over which a theory quantifies are real in the relevant sense. Irrealism denies that such commitment obtains universally. Antirealism replaces it with a universal denial. These positions do not merely differ in degree of confidence. They differ in the conditions they assign to meaning itself.
Theology cannot evade this problem. For theological discourse is theory-like: it quantifies, predicates, distinguishes, and orders claims concerning God and God’s relation to the world. If its syntax is to be meaningful, it must be interpreted. The decisive question is therefore not whether theology speaks, but what its speaking is taken to be about.
Realism, Irrealism, and Antirealism: A Logical Clarification
Let D be the domain over which a theory quantifies, and let R(x) signify that x is real in the sense required by the successful interpretation of the theory.
Realism affirms that for all x in D, R(x). If the entities quantified over are real, then the relations and functions defined over that domain are likewise taken to answer to reality. A realist construal of theory therefore holds that its models disclose, however fallibly, a genuinely mind-independent structure.
Irrealism is weaker. It denies that this universal claim obtains. It holds only that it is not the case that all members of the domain are real in the relevant sense. Some elements of the domain may be real, others not; some aspects of the theory may be referential, others merely heuristic, symbolic, or projected.
Antirealism is stronger. It claims that for all x in D, it is not the case that R(x). The discourse may remain coherent, useful, and even indispensable, but the entities over which it quantifies are not taken to belong to a mind-independent domain answering to the theory in the relevant way.
Schematically:
Realism: (x∈D)Rx
Irrealism: ~(x∈D)Rx
Antirealism: (x∈D)~Rx
The logical relation among these positions parallels the familiar distinction between reflexive, nonreflexive, and irreflexive relations. Realism affirms universal ontological commitment; irrealism denies that such universal commitment obtains; antirealism replaces it with a universal denial. The distinction is elementary, but its consequences are substantial.
The Semantic View of Theory
A theory is not best understood simply as a set of sentences or axioms, but as a structured family of models. Syntax alone does not yet yield meaning. A formal language may be internally coherent and inferentially rich while remaining semantically indeterminate unless interpreted.
Meaning arises from the relation between formal structure and interpreted structure. A model supplies a domain, assigns referents, and specifies relations and functions. The philosophical question is therefore not merely whether a theory is consistent or useful, but what kind of interpretation its models license.
This is where realism, irrealism, and antirealism emerge as competing construals of the relation between syntax, model, and world. A theory may function successfully while differing radically in what its success is taken to imply about the reality of the domain it describes.
From Scientific Theory to Theological Theory
Theological discourse belongs within this discussion more fully than is often recognized. It possesses theoretical form. It advances claims, deploys predicates, orders concepts, and licenses inferences. It speaks of God, creation, incarnation, grace, and redemption in ways that exhibit recognizable logical relations.
If this is so, then theological language too possesses a syntax in need of interpretation. The decisive question is therefore unavoidable: what sort of models render theological discourse meaningful?
A theological realist will answer that theological language is answerable to a reality independent of the discourse itself. A theological antirealist will preserve the discourse while redescribing its truth in terms of internal practice, communal rule, or warranted use. A theological irrealist will deny the universality of realist commitment, allowing a mixed or partial ontology.
Realism, Irrealism, and Antirealism in Theology
Theological realism affirms that the central terms of theological discourse answer to a reality independent of the discourse itself. God is not merely a name internal to a practice, nor a symbolic condensation of human aspiration. God is. Theological predicates therefore aim at truth in the strong sense.
Theological irrealism denies that such commitment holds across the entire domain. Some claims may be taken realistically, others symbolically or expressively. The result is a mixed and often unstable semantics.
Theological antirealism goes further. It denies that the entities over which theological discourse quantifies are real in the relevant sense at all. The discourse may remain meaningful within practice, but its function is no longer referential in the strong sense.
The Conditions of Theological Meaning
Theological meaning cannot be reduced either to formalism or to pragmatics. Syntax secures internal order but not reference. Practice secures use but not ontological answerability.
Theological meaning in its richest sense requires three moments:
- a syntax capable of disciplined articulation
- a semantic interpretation through models
- a domain with respect to which such interpretations may be true
Remove the third, and theology may retain significance, but it loses the realist truth-conditions by which it could speak of God as independently real.
Realism therefore does not add an optional metaphysical surplus. It secures the condition under which theological discourse can be about God rather than merely about itself.
Conclusion
The question is not whether theology may continue to speak under antirealist or irrealist construals. It plainly may. The question is what such speech is taken to be.
If theology is not answerable to a reality that is not constituted by its own discourse, then its claims no longer bear truth in the sense theology has historically intended. Realism does not remove mystery, nor does it resolve the limits of creaturely speech before God. But without it, theology’s language no longer reaches beyond itself.
With it, theology may yet speak of God as God is, and not merely of the uses of God-language within human life.
