What is a Theological Model?

This is the second part of a series developed through the Department of Philosophical Theology at Christ School of Theology, examining theological method, models, interpretation, and the logical and semantic conditions of theological inquiry.

From Method to Model

The first essay in this series argued that theological method concerns the disciplined ordering of sources, norms, concepts, and inferential procedures by which theologians seek truth concerning God and all things in relation to God. That formulation already implied something more. Once theologians begin arranging claims, distinguishing terms, identifying relations, and asking what follows from what, they are constructing representations of theological reality. They may speak instead of doctrinal systems, conceptual schemes, metaphysical accounts, explanatory frameworks, or simply interpretations, though in each case the activity exhibits a recognizable structure: certain claims are held fixed, certain entities are posited or presupposed, certain relations are specified, and the resulting structure is examined for coherence, adequacy, and explanatory power.

This is the point at which talk of theological models becomes useful, though it can also become treacherous. The word ‘model’ has several senses, and theologians often move among them without noticing the transition. A model can be an exemplar to be imitated; it can be a simplified representation of some object; it can be a theoretical construction employed to explain phenomena; and, in logic, it can be a structure in which the sentences of a theory are satisfied. These senses overlap, though they are hardly identical. If we wish to speak perspicuously about theological models, some semantic housekeeping is therefore required.

The purpose of such housekeeping is not to reduce theology to formal logic. That would merely substitute one methodological imperialism for another. Yet model theory supplies distinctions that theologians badly need, because it forces us to distinguish a language from an interpretation of that language, a theory from a structure satisfying that theory, and satisfaction within a structure from truth simpliciter. Once those distinctions are seen, several perennial theological confusions become considerably easier to diagnose.

Theory and Model

Suppose we begin with a language L containing certain predicates, relations, constants, and perhaps other logical or nonlogical expressions. Within that language we formulate a set of sentences T. This set of sentences constitutes a theory in the broadly logical sense. The theory says certain things, or at least provides sentences capable of saying them once its expressions are interpreted.

A model of T is then a structure M in which every sentence belonging to T is satisfied.

In abbreviated form:

M ⊨ T

This is read: ‘M is a model of T,’ or more explicitly, ‘every sentence in T is true in M under the relevant interpretation.’

Already the theological significance should be apparent. The theory and the model are not identical. T consists of sentences. M is a structure relative to which those sentences receive an interpretation and are satisfied. If one forgets this distinction, one can easily slide from talking about a doctrinal formulation to talking as though the formulation itself were the theological reality.

Consider, for example, a highly simplified Trinitarian theory containing sentences expressing that the Father is divine, the Son is divine, the Spirit is divine, the Father is not the Son, the Son is not the Spirit, and the Father is not the Spirit. These sentences constrain acceptable interpretations. They rule some structures out. Yet they do not, merely by being stated, determine a unique metaphysical account of divine triunity. More than one structure may satisfy the same set of sentences, depending upon how ‘divine,’ ‘person,’ identity, relation, and the domain itself are interpreted.

That is precisely why theological models arise. They attempt to exhibit ways in which a set of theological assertions might jointly be true.

A Model Is an Interpretation

In elementary model theory, one often represents a structure in something like the following way:

M = ⟨D, I⟩

Here D is a nonempty domain of objects, while I is an interpretation assigning semantic values to the nonlogical vocabulary of the language. If P is a one-place predicate, I assigns to P some subset of D; if R is a two-place relation, I assigns to R some set of ordered pairs from D; if a is a constant, I assigns to a some member of D.

Thus, if P means ‘is divine,’ then Pᴹ is the extension of P in M: the objects in the domain that satisfy the predicate. If R means ‘begets,’ then Rᴹ consists of those ordered pairs ⟨x,y⟩ such that x stands in the begetting relation to y.

The notation can appear forbidding only until its philosophical point is grasped. A model interprets a language by assigning structure to its vocabulary. It tells us what the terms range over, which objects instantiate which predicates, which objects stand in which relations, and under what conditions the sentences of the theory come out true.

Theological argument does this constantly, usually without the notation. When a theologian says that ‘person’ in Trinitarian discourse denotes a subsistent relation rather than an individual substance, an interpretation has been supplied. When another theologian says that ‘nature’ in Christology is neither a concrete individual nor merely a set of properties, another interpretation has been proposed. When a theologian distinguishes between divine action as temporal causal intervention and divine action as the sustaining condition of creaturely actuality, the semantic structure assigned to ‘acts’ has changed. The dispute may accordingly appear grammatical while being fundamentally ontological.

Models and Reality

At this point, however, a caveat becomes indispensable. In formal semantics, a model is often treated simply as a mathematical structure. In theology, matters cannot end there, because theological assertions purport to concern reality. A model may satisfy a theory without thereby establishing that the theory is true of God. This distinction is absolutely fundamental.

Suppose M ⊨ T. We have shown that there is at least one interpretation under which every sentence in T is satisfied. We have not thereby shown that T is true simpliciter. Still less have we shown that M reproduces the ontological structure of divine reality.

The distinction can be put bluntly. Consistency is not truth. Satisfiability is not actuality. Model-theoretic success is not metaphysical vindication.

Yet the converse error must also be resisted. Because a model does not establish truth, it does not follow that models are theologically unimportant. A model can reveal that some set of claims is jointly satisfiable; it can expose hidden assumptions; it can show that an apparent contradiction depends upon an equivocation; it can reveal commitments that were previously unnoticed; and it can make competing interpretations sufficiently explicit that genuine disagreement becomes visible.

Models therefore perform an indispensable mediating function. They stand between language and reality, not because reality itself is constructed, but because our intellectual access to complex claims requires structured representations.

The Given and the Made

This is one place where the distinction between the given and the made becomes especially useful. The theological model is made. Its vocabulary is selected, its distinctions introduced, its relations specified, and its inferential consequences explored. God, if Christian theology is correct, is not made by this activity. Neither is Christ's incarnation, the resurrection, justification, or the presence of Christ in the Eucharist constituted by the conceptual structures through which theologians seek to understand them.

There is therefore an asymmetry between reality and representation. The theologian can revise the model without revising God. One can replace one account of divine simplicity with another, refine a Christological ontology, or abandon an inadequate construal of sacramental presence without supposing that the divine reality altered while the theologian was sharpening the concepts.

This asymmetry might seem obvious, though theological controversies repeatedly obscure it. A favored conceptual scheme acquires such authority that criticism of the scheme is experienced as criticism of the doctrine itself. Conversely, rejection of a particular metaphysical model is sometimes mistaken for rejection of the reality that model sought to articulate. The theologian who distinguishes these levels gains considerable freedom. One can defend the doctrine while criticizing a model of the doctrine; one can preserve the confession while revising an ontology thought necessary to sustain it.

This distinction is especially important in philosophical theology, where metaphysical language carries enormous explanatory power and corresponding danger. Categories such as ‘substance,’ ‘relation,’ ‘property,’ ‘essence,’ ‘person,’ ‘nature,’ ‘event,’ and ‘state of affairs’ can illuminate theological claims, though none arrives innocent of philosophical history. They bring inferential consequences with them. Model construction allows those consequences to become visible.

The Underdetermination of Models

A further complication now appears. A theory may have many models.

In logical notation:

M₁ ⊨ T
M₂ ⊨ T
M₃ ⊨ T

Each of these structures satisfies T, though the structures themselves may differ substantially.

The theological importance of this possibility can scarcely be exaggerated. A doctrinal formulation may constrain interpretation without determining a unique metaphysical account. Indeed, much theological disagreement may arise precisely because multiple models satisfy what disputants regard as nonnegotiable doctrinal claims.

The Nicene confession, for example, rules out certain accounts of the Son. Chalcedon rules out certain Christologies. The Lutheran Confessions exclude certain interpretations of justification and sacramental presence. Yet exclusion is not the same thing as complete determination. A confession can establish boundaries without specifying a single exhaustive ontology within those boundaries.

This is not an argument for doctrinal relativism. Quite the opposite. If several models satisfy some doctrinal theory T, one must ask what further criteria might discriminate among them. Biblical adequacy, confessional fidelity, historical continuity, explanatory scope, semantic perspicuity, ontological economy, inferential stability, and philosophical coherence may all become relevant. Yet these criteria themselves must be ordered, and their authority is not self-interpreting. We have thereby returned to method.

Models Can Reveal More Than We Put Into Them

An additional feature of model construction deserves notice. Models can disclose consequences that were not obvious when the model was first built. Once one assigns meanings, specifies relations, and formalizes commitments, one may discover that the resulting structure entails something unexpected.

This is among the genuine intellectual benefits of formal and semi-formal theological modeling. Human beings are notoriously poor at keeping track of large networks of conceptual commitments. We affirm A because it appears independently plausible, B because it accords with a doctrinal source, and C because it solves a philosophical difficulty, only later to discover that A, B, and C jointly imply D, which nobody wanted.

A model can force this discovery.

The point is analogous to proof in logic. One often knows the premises before knowing their consequences. Formalization renders latent structure explicit. Theology has sometimes resisted such procedures out of fear that formal methods somehow diminish mystery, though the objection is misplaced. Logic does not render divine reality transparent; it renders our own commitments more transparent. Those are very different achievements.

If there is mystery, it belongs to the object. Confusion belongs to us. The theologian ought not baptize the latter with the name of the former.

The Model Is Not the Doctrine

We can now state another distinction that deserves almost aphoristic emphasis: a theological model is not identical with the doctrine it models. Doctrine ordinarily consists of normative or authoritative theological claims embedded within an ecclesial, biblical, and historical context. A model is a structured interpretation intended to show how such claims might be understood as jointly true.

Consequently, criticism of a model does not ipso facto constitute rejection of a doctrine. Nor does successful defense of a model necessarily establish the doctrine itself. The levels must be held apart.

This distinction is particularly useful when theology encounters modern metaphysics. One theologian may model divine omniscience through possible worlds, another through propositions, another through divine self-knowledge, and still another through a metaphysics of truthmaking. They may disagree profoundly about ontology while confessing substantially the same doctrine. Alternately, two theologians may employ nearly identical metaphysical machinery while differing at the doctrinal level because they assign different normative status to biblical or confessional claims. Without a distinction between doctrine and model, these disagreements become almost impossible to classify.

What Makes a Model Theological?

We can now risk a provisional answer. A theological model is a structured interpretation constructed to represent how a set of theological claims may be jointly true and how the entities, properties, and relations presupposed by those claims might be understood.

The definition is intentionally modest. A model does not claim exhaustive correspondence with divine reality. It does not manufacture its object. It does not replace Scripture, confession, proclamation, or worship. Rather, it makes conceptual commitments explicit so that they can be examined.

The adjective ‘theological’ matters because theological models are not free-standing constructions. They arise within an inquiry governed by theological sources and norms. Their adequacy cannot therefore be measured solely by elegance, simplicity, or formal consistency. A model of the Trinity that is internally impeccable but incompatible with the claims that generated Trinitarian doctrine is a poor theological model, however admirable it may be as an exercise in metaphysics.

Conversely, appeals to theological authority do not absolve a model from philosophical scrutiny. If a proposed interpretation is inconsistent, equivocal, semantically unstable, or ontologically extravagant, such defects matter. Theology qua theology may have distinctive sources and norms, but it does not thereby enter a logical sanctuary in which contradiction becomes virtue.

Toward Satisfaction and Truth

We are now in a position to see the next problem. If a model supplies an interpretation under which theological sentences are satisfied, what exactly is the relation between satisfaction and truth?

When we write

M ⊨ φ

we say that φ is satisfied in M. But theology wants eventually to say more than that some sentence comes out true under some interpretation. It wants to ask whether what φ says is actually the case.

That transition is neither automatic nor trivial. It carries us from formal semantics toward questions of reference, truth, realism, and theological knowledge. It also forces us to confront one of the most seductive confusions in philosophical theology: the tendency to mistake truth-in-a-model for truth about reality.

Accordingly, the next essay in this series will ask: What does it mean for a theological claim to be satisfied, and what does satisfaction have to do with truth?

That question will take us further into model theory, though it will also bring us closer to theology's oldest intellectual ambition: not merely to construct coherent representations of God, but, insofar as creaturely judgment permits, to say truly what is the case.

What Is Theological Method?

This is the first part of a new series developed through the Department of Philosophical Theology at Christ School of Theology, examining theological method, models, interpretation, and the logical and semantic conditions of theological inquiry.

The Question of Method

Theological disputes regularly present themselves as disputes about conclusions. One theologian avers that God acts in history while another worries that such language compromises divine transcendence; one insists upon the real presence of Christ in the Supper while another seeks a conceptual account capable of preserving what is taken to be the relevant biblical affirmations; one theologian speaks readily of divine simplicity while another suspects that the metaphysical apparatus required to sustain the doctrine creates more difficulties than it resolves. Yet beneath disagreements of this kind there usually lies another disagreement, frequently less explicit and sometimes more consequential: What counts as an appropriate way of arriving at a theological judgment in the first place?

The question of theological method therefore arises prior to many of theology's more familiar questions. Before one asks what theologians ought to conclude about some matter, one must ask what kinds of considerations legitimately bear upon the conclusion, how these considerations are related, what authority they possess, and according to what rules conflicting considerations are to be adjudicated. Method concerns, inter alia, what theologians count as evidence, what kinds of inference they permit, what distinctions they regard as legitimate, and what conditions a theological claim must satisfy if it is to be judged warranted.

The matter becomes still more difficult because theology does not operate within a single homogeneous discourse. Biblical texts, historical claims, creedal formulations, metaphysical assertions, phenomenological descriptions, liturgical practices, and logical consequences all appear within theological reasoning, though they plainly do not function in precisely the same way. The theologian who ignores these differences risks confusing the authority of a text with an interpretation of that text, an interpretation with a philosophical reconstruction of it, and that reconstruction with the reality about which the text putatively speaks. Accordingly, method is no mere preliminary housekeeping exercise. It belongs to theology's substantive intellectual work.

Method and Object

A method is ordinarily selected because of the object one seeks to understand. One does not investigate a mathematical structure in precisely the same way that one investigates a historical event, nor does one investigate a chemical reaction in the manner appropriate to interpreting a poem. The character of the object places constraints upon the procedures by which knowledge of that object may responsibly be sought.

This apparently innocent observation carries considerable theological weight. If theology has God as its ultimate object, then theological method cannot be determined wholly in advance by epistemological principles borrowed from some other domain. The theologian cannot simply announce a universally valid method and subsequently inquire whether God happens to fit within it. At least prima facie, the order must run in the other direction: what God is determines what could count as knowledge of God.

Christian theology intensifies the point because it claims that God is known through God's own acts of self-disclosure. Theology consequently begins within a peculiar epistemic situation. Its object is never simply an object standing passively before an autonomous observer. God is confessed as the one who creates the knower, sustains the knower, addresses the knower, judges the knower, and reconciles the knower. Theological knowledge, on such an account, cannot be understood simply as the successful application of a neutral human technique to a religious datum.

This does not entail intellectual obscurantism, nor does it grant theology dispensation from ordinary standards of argument. Quite the contrary. If theological claims purport to be true, then distinctions between valid and invalid inference, consistency and inconsistency, ambiguity and perspicuity, use and mention, entailment and non-entailment remain indispensable. The peculiar character of theology's object qualifies theological method without abolishing rational discipline.

Sources, Norms, and Procedures

It is useful here to distinguish three matters that theological discussions of method frequently conflate: sources, norms, and procedures.

A source supplies material for theological reflection. Scripture is a source; so are creeds, confessions, liturgical practices, historical testimony, philosophical arguments, and the accumulated conceptual vocabulary of the Christian tradition. Different theological traditions will disagree, of course, about the relative status of these sources, but identifying something as a source does not by itself determine what authority it possesses.

A norm performs another function. A norm governs theological judgment. Within classical Lutheran theology, Scripture does not stand merely as one theological source among several; it functions normatively in a manner in which Augustine, Aquinas, Luther, or the Formula of Concord does not. Precisely how such normativity is understood opens a host of hermeneutical questions, though the logical point can be made independently of their eventual resolution: the set of materials from which theology learns and the standards by which theological claims are judged need not be coextensive.

A procedure, finally, concerns what theologians do with sources under the governance of norms. They interpret texts, distinguish senses of terms, draw consequences, construct conceptual models, compare formulations, identify contradictions, trace historical development, and ask whether competing accounts preserve or obscure the phenomena requiring explanation. Much that is ordinarily called theological ‘method’ actually belongs at this procedural level.

Once these distinctions are made, certain familiar methodological quarrels become more perspicuous. A disagreement apparently concerning Scripture may turn out to concern an interpretive procedure; a disagreement ostensibly concerning metaphysics may concern the normative authority granted to some doctrinal formulation; a dispute about a theological model may finally rest upon disagreement about which biblical or confessional claims the model must preserve.

Method Does Not Manufacture Its Object

A perennial temptation arises whenever a method proves especially powerful. What begins as an instrument of inquiry gradually becomes a criterion of reality itself. Whatever the method cannot capture comes to be regarded as confused, meaningless, inaccessible, or unreal.

The history of philosophy provides abundant examples. What cannot be verified is declared meaningless; what cannot be phenomenologically given is placed in abeyance; what cannot be expressed within a particular logical language is treated as philosophically suspect; what cannot be naturalized is relegated to the realm of projection. Each maneuver may illuminate something important, though each can also convert a methodological decision into an ontological decree.

Theology must be especially attentive to this temptation. A theological method is made; God is not. Conceptual structures are constructed; the reality to which theological language refers is not thereby constructed. We formulate doctrines, distinguish concepts, erect models, and test their consequences, but these activities must not be confused with the reality they seek to articulate.

This distinction between the given and the made will become increasingly important as this series proceeds. Theologians necessarily make models. They select terms, introduce distinctions, formalize relations, and construct conceptual structures within which doctrinal claims can be understood. Such making is unavoidable and frequently fruitful. Difficulties begin when the structure of the model is silently transferred to the structure of reality, so that what belongs to our representation is treated as belonging ipso facto to that which is represented.

Caveat lector: the point does not entail that theological models are arbitrary. Some models represent their subject matter better than others. Some preserve relevant doctrinal affirmations while others distort them; some disclose consequences previously unnoticed while others conceal precisely what must be explained. Yet the distinction between model and modeled reality remains indispensable to judging any model at all.

Theological Method as Disciplined Judgment

We can now risk a provisional definition. Theological method is the disciplined ordering of sources, norms, concepts, and inferential procedures by which theologians seek truth concerning God and all things in relation to God.

Each part of this definition matters. Method is disciplined because theological inquiry cannot proceed merely by association or intuition. It involves ordering because sources, norms, concepts, and arguments do not arrive already assembled into a theological system. It seeks truth because theology claims more than internal coherence within a religious language-game. And its subject matter includes ‘all things in relation to God’ because theology has historically concerned creation, humanity, sin, history, church, sacrament, death, resurrection, and consummation precisely sub specie relationis ad Deum.

The phrase ‘seek truth’ should also remain firmly in view. Method does not guarantee truth. No procedure can do that. A perfectly executed inference may proceed from a false premise; an internally coherent theological model may misdescribe reality; an elegant conceptual system may succeed brilliantly at explaining claims that ought themselves to be rejected. Method disciplines judgment without rendering judgment apodictic.

The theologian therefore inhabits an unavoidable tension. Theology requires method because thinking without methodological discipline easily collapses into equivocation, inconsistency, and rhetorical assertion. Yet theology must also submit its methods to criticism because no human method enjoys an unrestricted view of its object. The method serves the inquiry; the inquiry does not exist to vindicate the method.

From Method to Models

This brings us to the question that will occupy the next stage of the argument. Once theologians begin ordering doctrinal affirmations, clarifying their relations, and asking what must be true if those affirmations are true, they inevitably begin constructing models. They may not call them models, and they may resist the vocabulary of model theory altogether, but the activity remains recognizable. Certain entities are assumed, relations among them are specified, propositions are held fixed, and the consequences of alternative interpretations are explored.

Accordingly, the next question is unavoidable: What is a theological model?

Answering it will require us to distinguish a model from a theory, a theory from its interpretation, an interpretation from the reality interpreted, and satisfaction within a structure from truth simpliciter. These distinctions might initially appear technical. In fact, they bear directly upon some of theology's oldest disputes, because theologians have often disagreed less about the sentences they confess than about the structures within which those sentences are taken to be true.

The question of method thus leads naturally to the question of models. And once models enter the discussion, logic, semantics, and ontology cannot remain far behind.

Reality Does More than Resist; It Corrects

This essay continues an ongoing series in philosophical theology from the Department of Philosophical Theology at Christ School of Theology. The series asks a few basic but demanding questions: What makes reality intelligible? How does theological language work? What philosophical assumptions support Christian belief? Behind it stands a simple conviction: theology exists because these questions exist, and its first task is to make Christian doctrine intelligible without reducing, replacing, or explaining away the reality to which that doctrine points.

The previous essay argued that reality has the first word. Inquiry does not begin because an isolated subject decides to direct its attention toward an otherwise indifferent world. It begins because something has already presented itself, interrupted our expectations, resisted our descriptions, or called our understanding into question. Before we formulate a hypothesis, devise an experiment, or construct a theory, something has already occasioned the inquiry.

That claim reverses an order of explanation deeply embedded in modern thought, which imagines us first as active knowers who subsequently turn toward reality as an object of intellectual activity. The actual experience of inquiry suggests otherwise. Reality does not enter the process only after we have begun asking questions; the questions arise because reality has already refused to remain unnoticed.

From resistance to correction

Resistance alone, however, does not explain inquiry. A locked door resists the body. A steep hill resists the traveler. A malfunctioning machine resists its operator's intentions. Such resistance may frustrate us, delay us, or force a change of behavior, but it does not yet constitute correction.

Intellectual inquiry requires something more: reality must be capable not merely of impeding our purposes but of showing that an account of it is inadequate. A scientist whose prediction fails does not conclude that nature has simply been uncooperative; she asks whether the theory, the measurement, or the experimental design was mistaken. A historian who discovers a document inconsistent with a familiar narrative does not treat it as an obstacle to a preferred interpretation; he asks whether the narrative must be revised. A philosopher who finds a contradiction within an argument does not treat it as an unfortunate collision of equally acceptable possibilities; she recognizes that something has gone wrong. In each case, reality does more than resist. It corrects.

To be corrected is not merely to be pushed in a different direction. It is to discover that one ought to think differently because one's previous account has failed to do justice to its object. This "ought" is already present in every serious inquiry. We do not prefer a revised theory merely because it is newer; we judge it more adequate. We do not abandon a historical interpretation because another has become fashionable; we abandon it because the evidence no longer supports it. We do not reject an argument because it is rhetorically inconvenient; we reject it because its conclusion does not follow or its premises cannot be sustained.

Inquiry is therefore normative from the beginning, for it distinguishes better from worse descriptions, more and less adequate explanations, responsible from irresponsible judgments. Without such distinctions there may still be curiosity, experimentation, or invention, but there is no disciplined search for understanding.

The limits of construction

This is where many contemporary accounts of knowledge become unstable. They rightly emphasize that human knowing is historically situated, linguistically mediated, socially conditioned, and conceptually structured. No one encounters reality from nowhere; every observation occurs within practices of interpretation, and every judgment employs concepts inherited from particular traditions. Yet none of this explains how those practices, concepts, and traditions can themselves be corrected. A community may share an interpretation and still be mistaken. An inherited narrative may organize experience powerfully while concealing what actually occurred. A conceptual scheme may be internally coherent while systematically misdescribing its object. Even a theory of knowledge that insists all knowledge is socially constituted must distinguish a more adequate account of that constitution from a less adequate one.

The language of construction, then, cannot be the final word. Human beings undoubtedly construct theories, models, narratives, and conceptual frameworks. The planetary model, the economic model, the historical narrative, and the theological system all result from acts of selection, abstraction, and representation; no model reproduces its object without mediation. Construction is therefore not the enemy of realism—it is one of the conditions under which finite beings become capable of understanding anything at all. The relevant question is not whether our models are constructed, but whether they remain answerable to what they seek to understand.

The difficulty arises when the constructed character of a model is taken to mean that it owes nothing beyond itself. At that point coherence replaces adequacy, usefulness replaces truth, and a model's capacity to organize discourse matters more than its capacity to disclose its object. A model may be coherent and still false. It may be useful and still distort what it represents. It may secure agreement among those who employ it while excluding every consideration that would expose its inadequacy. That a model works for some purpose does not establish that it has understood the reality with which it deals.

This becomes especially clear when models meet anomalies. An anomaly is not simply something unexpected; it is something that ought not to have occurred if the model were adequate. Its significance lies in the tension between what the model permits us to expect and what reality actually presents. Yet even anomalies do not automatically correct us—human beings are remarkably skilled at protecting favored explanations from inconvenient evidence, whether by dismissing exceptions, redefining terms, altering standards of evidence, questioning a critic's motives, or introducing auxiliary explanations whose real function is to prevent the original account from being tested. A model becomes intellectually responsible only when it permits reality to count against it.

That sentence sounds obvious, but much depends on it. Inquiry requires more than the availability of evidence; it requires a willingness to let evidence exercise normative force. Reality must be granted the authority to expose not only that our expectations have failed, but that our descriptions must change.

The third partner

This is why inquiry always includes what might be called a third partner. There is the knowing subject, with a history, language, community, and set of intellectual practices. There is the theory, model, or interpretation through which the subject seeks understanding. And there is the reality the model intends to disclose.

This third partner cannot be absorbed into either of the others. It is not merely a projection of the knowing subject, because it continually resists what the subject would prefer to find. Nor is it identical with the model, since competing models may address the same reality, and every model remains open to correction by what it fails to preserve.

Once this third partner disappears, inquiry changes character. Disagreement becomes a contest between perspectives rather than a shared attempt to understand something that exceeds them both. Theories are assessed by the identities they sustain, the interests they serve, or the effects they produce, and questions of truth are gradually redescribed as questions of power, coherence, usefulness, or social location. These considerations are not illegitimate—intellectual practices do involve power, interpretations do arise from particular social locations, theories do have consequences—but none of them explains why an account of power, location, or consequence should itself be accepted as more adequate than its alternatives. Even the critique of truth must present itself as a truthful critique.

This inescapability suggests that correction belongs more deeply to inquiry than any particular theory of knowledge does. Before we decide whether we are realists, idealists, pragmatists, or constructivists, we have already distinguished claims that illuminate reality from claims that obscure it, and assumed that inquiry can disclose why one judgment should replace another. The phenomenon is familiar enough that we scarcely notice it: a physician changes a diagnosis because the patient's condition does not fit the original account; a mechanic abandons one explanation of an engine failure because the parts do not behave as predicted; a child revises an assumption about another person because that person's actions keep contradicting it. In each case, understanding advances when the object is permitted to instruct the one seeking to understand it.

This instruction need not arrive as a complete answer. Reality seldom interprets itself in finished form; it confronts us through anomalies, contradictions, absences, patterns, and unexpected relations. We must still reason, imagine, compare, and construct. Correction does not eliminate the active work of the knower—it places that work under judgment.

Creativity and humility

Genuine inquiry therefore requires both creativity and humility. Creativity, because reality does not hand us ready-made conceptual schemes; we must devise models capable of rendering its order intelligible. Humility, because no model can claim immunity from the reality it seeks to understand. The deepest intellectual failure occurs when creativity is preserved but humility is lost—when inquiry becomes the art of producing ever more sophisticated constructions without allowing anything outside those constructions to judge them. The result may be ingenious, influential, even institutionally successful. It will not be understanding.

What correction requires of reality

The claim that reality corrects us goes beyond asserting that a world exists independently of human thought. A merely independent reality could remain mute, chaotic, or wholly unintelligible; it might resist our actions without providing any basis for distinguishing a better description from a worse one. Correction requires more than independence. It requires order.

Reality must possess determinate features and relations that our descriptions can preserve or distort. It must be stable enough that inquiry can discover patterns, rich enough that our first descriptions remain incomplete, and intelligible enough that failure can become the occasion for improved understanding. The normativity of inquiry is not imposed on reality from outside; it arises within the encounter between finite understanding and an order that exceeds it. We discover that we ought to revise our judgments because reality has shown them to be inadequate.

None of this makes correction final. Later inquiry may expose weaknesses in what presently appears to be the better account, and reality does not speak unambiguously—evidence must be interpreted, and reasonable people may disagree about what a given anomaly requires. But fallibility does not abolish correction; it makes correction necessary. The possibility of error presupposes a difference between what we believe and what is the case. The possibility of learning presupposes that this difference need not remain permanent. Inquiry inhabits the space between them—the space in which reality can unsettle our judgments and call forth more adequate ones.

Toward the next question

We can now state the advance beyond the previous essay. Reality has the first word because inquiry begins in response to what confronts us. But that first word is not merely the brute announcement of presence—it is also a claim upon our understanding. Reality does not merely say, "I am here." It says, "You have not yet understood me."

That claim gives inquiry its peculiar dignity. Human beings do not merely adjust themselves to their environments; they seek to become answerable to what is real. They recognize, however imperfectly, that an inadequate description ought to be revised, and that understanding bears responsibilities not exhausted by usefulness or success.

The question that now emerges is deeper still. Norms such as truth, adequacy, and explanatory superiority are not objects situated alongside other objects. We do not observe adequacy as we observe a tree, a molecule, or a distant planet. Yet without such norms, no observation becomes evidence and no theory becomes corrigible. What kind of reality can call forth not merely causal reactions but responsible judgments? What must the world be like if it not only resists our constructions but teaches us how those constructions have failed?

Reality has the first word. We must now ask how that word becomes intelligible as correction.

Prolegomena to Disputationes Theologicae IV: Truth Before Appropriation

“Christian doctrine cannot be appropriated until it is first capable of truth.”

This essay is the fourth of six Prolegomena to Disputationes Theologicae, a series in philosophical theology produced through the Department of Philosophical Theology at Christ School of Theology. Together, these essays articulate the methodological foundations of the larger Disputationes Theologicae project by recovering the proper order of theological inquiry. They proceed from the conviction that theology exists because these questions exist and that theology’s first responsibility is to render Christian doctrine intelligible without diminishing, translating away, or replacing the reality to which it refers. Having argued that theological language must first become intelligible and genuinely referential, the present essay asks the next necessary question: Under what conditions can theological judgments be true?

The preceding essays established that theology begins with the questions that make theology necessary, that Christian doctrine must be rendered intelligible, and that theological language must genuinely refer to the God whose self-disclosure gives theology its subject matter. Yet neither intelligibility nor reference completes theology’s task. A sentence may be perfectly intelligible, and its principal terms may successfully identify their referents, while the sentence itself remains false.

The decisive question therefore emerges: When is Christian doctrine true? This question is not one concern among others. It is the question upon which the theological importance of all the others finally depends.

Modern theology has frequently displaced this question. It has asked whether theological language is existentially meaningful, ecclesially authorized, morally fruitful, politically liberating, psychologically transformative, narratively coherent, or liturgically effective. Each of these questions may be legitimate, and some are indispensable to the life of the Church. Yet none of them can substitute for the prior question of whether the doctrine being interpreted, proclaimed, practiced, or appropriated is true.

Theology is not finally justified by its usefulness. A belief may console, motivate, unify, discipline, or transform while nevertheless being mistaken. Nor is theology finally justified by its capacity to sustain a community across time. Ecclesial continuity may preserve truth, but continuity itself cannot make a doctrine true.

The first responsibility of theology is therefore not to demonstrate what Christian doctrine accomplishes within human life. It is to ask whether what Christian doctrine says is the case. Theology is concerned with usefulness, proclamation, faith, worship, ethics, and ecclesial continuity because it is first concerned with truth.

This ordering is easily misunderstood. To insist upon truth is not to advocate an abstract rationalism that forgets faith, worship, proclamation, or discipleship. Nor is it to imagine that finite creatures occupy an unmediated standpoint from which divine reality may be inspected independently of revelation. Theology remains historically situated, linguistically mediated, conceptually finite, and wholly dependent upon God’s self-disclosure.

Mediation, however, does not abolish truth. On the contrary, revelation presupposes that something is the case before and apart from our acknowledgment of it. Revelation may transform our understanding of reality, but it does not create the reality disclosed merely by being received.

Theological realism therefore begins with a simple conviction: God is not constituted by theological language. Ecclesial confession, theological reflection, religious experience, and liturgical practice do not bring God into being. They neither create their referent nor determine the reality to which they answer.

Theology exists because God exists and has acted. Christian doctrine is therefore accountable to realities that do not depend upon theological discourse for their existence. God’s reality is not a consequence of the Church’s grammar, and God’s acts are not made actual by the community’s interpretation of them.

This is why truth must be distinguished from several neighboring concepts with which it is frequently confused. These distinctions are not philosophical refinements imposed upon theology from without. They arise from theology’s own claim to speak responsibly about God and God’s works.

Truth is not coherence. A doctrinal system may be internally consistent, elegantly ordered, and inferentially disciplined while nevertheless failing to describe reality. Coherence is a necessary virtue of theology, but a coherent fiction remains fiction.

Truth is not usefulness. A doctrine may sustain a community, shape character, provide consolation, and inspire sacrificial action while still being false. Practical fruit cannot by itself determine the reality of the seed from which it is said to grow.

Truth is not ecclesial authorization. Churches possess genuine authority to teach, confess, discipline, and proclaim. Yet ecclesial authority serves truth; it does not constitute truth merely by exercising itself.

Truth is not felicity. An utterance may achieve its intended performative effect without accurately predicating what is the case. A proclamation may move, accuse, console, or reconcile while remaining confused about the reality in whose name it speaks.

Truth is not warrant. One may possess strong reasons for believing a proposition and still be mistaken. Warrant concerns the responsibility of belief; truth concerns whether what is believed is actually the case.

Nor is truth identical with sincere faith. Faith trusts what is given as true; it does not make its object true by the intensity, authenticity, or existential seriousness of its trust. The sincerity of belief cannot transform falsehood into truth.

These distinctions reveal why theological truth cannot be reduced to the internal life of Christian discourse. Christian doctrine does not merely express religious attitudes, organize ecclesial practices, or articulate a communal form of life. It makes judgments about God, creation, sin, incarnation, reconciliation, resurrection, judgment, and the consummation of all things.

Such judgments are truth-apt because they predicate something of realities they intend. To say that God created the world, that the Word became flesh, or that Jesus Christ was raised from the dead is not merely to display a Christian attitude toward existence. It is to say that something happened and that reality is accordingly different from what it would have been had it not happened.

Truth-aptness must, however, be distinguished from truth itself. A sentence becomes capable of truth or falsity when it is sufficiently intelligible, when its terms successfully refer, and when it predicates something determinate of what it identifies. Only then can the further question arise whether the predicate truly belongs to the referent.

The order is therefore exact. Intelligibility makes judgment possible. Reference gives judgment a subject. Predication says something determinate of that subject. Truth concerns whether what is predicated is actually the case.

This also explains why the previous essay’s insistence upon reference was necessary but insufficient. Successful reference does not guarantee true predication. One may refer successfully to God while saying something false about God, just as one may identify a person correctly while misdescribing that person’s character or actions.

Theology must therefore remain answerable not only for whom it names but also for what it says of the one named. Referential continuity preserves the subject matter of theology; truth determines whether theological judgment is faithful to that subject matter.

The demand for truth also distinguishes theology from the mere demonstration of logical or metaphysical possibility. To show that a doctrine is internally coherent, noncontradictory, or metaphysically possible is an important achievement. It may remove confusions, answer objections, and establish that the doctrine is not irrational merely in virtue of its form.

Possibility, however, is not actuality. A doctrine may be coherent without being true, and a possible account of God may fail to describe the God who actually exists. Theology therefore seeks more than consistency and more than possibility. It seeks responsible judgment concerning who God is and what God has done.

This point is especially important for philosophical theology. Philosophy clarifies concepts, distinguishes categories, disciplines inference, examines presuppositions, and exposes confusion. It can show that an apparent contradiction is not genuine, that a distinction has been overlooked, or that an argument fails to establish its conclusion.

Philosophy cannot, however, supply the truth of Christian doctrine from its own resources. The truth of Christian doctrine remains grounded in the reality of God’s self-disclosure. Philosophy serves theology precisely by refusing both to replace revelation and to exempt theological claims from conceptual and logical scrutiny.

Theology therefore proceeds according to a definite architectonic order. It first asks whether its language is intelligible, because unintelligible language cannot yet express a responsible judgment. It then asks whether its language genuinely refers, because meaningful discourse that fails to identify its subject remains theologically empty.

Only after intelligibility and reference have been secured can theology ask whether what it predicates is true. Only after truth has become a genuine possibility do proclamation, appropriation, ethics, spirituality, ecclesial life, and cultural engagement assume their proper theological place.

This order does not diminish faith. It protects faith from being asked to trust what theology has never adequately clarified, from being directed toward a referent theology has failed to identify, or from being confused with the power to make doctrine true through believing it.

Nor does this order diminish proclamation. It protects proclamation from becoming eloquence detached from reality, religious performance sustained by effect, or ecclesial speech that substitutes authority for truth. Proclamation may become divine address only because it bears witness to what is independently true of God and God’s acts.

Neither does this order diminish the Church. It protects the Church from confusing fidelity to inherited formulations with fidelity to the reality toward which those formulations point. The Church preserves its doctrinal inheritance faithfully only when it remains answerable to the truth that inheritance intends.

Theology therefore seeks truth before appropriation. Appropriation concerns the reception of truth within the life of the believer and the community. It includes trust, obedience, worship, consolation, repentance, transformation, vocation, and hope.

These are not dispensable additions to an otherwise complete intellectual system. Christianity would be reduced to a dead letter without faith’s reception of the gospel. Yet appropriation presupposes that there is something real to appropriate and something true to believe.

Faith does not create its object. It receives what God gives.

Truth belongs to the relation between judgment and reality. Faith belongs to the creature’s reception of the reality truthfully judged. Theology stands between revelation and appropriation, seeking to articulate as responsibly as possible what God has disclosed and what Christian doctrine therefore claims to be true.

This does not mean that theology first achieves an exhaustive and indubitable body of truths and only afterward permits faith to begin. The order is methodological and theological rather than simply chronological. Faith, proclamation, inquiry, and judgment occur together within the actual life of the Church.

Nevertheless, their logical relations must not be confused. Appropriation cannot determine truth without becoming projection, just as proclamation cannot determine its own referent without becoming self-authorizing speech. Faith may deepen understanding, but it does not convert false predication into true predication.

Theology’s governing order may therefore be stated succinctly: intelligibility, reference, truth, appropriation. Each moment presupposes the preceding one, and none may simply replace another.

Without intelligibility, doctrine cannot be responsibly understood. Without reference, doctrine cannot be genuinely about God. Without truth, doctrine cannot rightly claim faith. Without appropriation, truth remains unreceived within creaturely life.

The third moment is architectonically decisive. Intelligibility and reference open theological discourse toward truth; appropriation, proclamation, and ecclesial life receive and enact what is true. Truth therefore stands neither at the beginning nor at the end of theology’s order, but at its pivotal center.

Only what is intelligible can become truth-apt. Only what refers can become true or false of its intended subject. Only what is true can finally become an object of faith rather than merely an instrument of religious formation.

The next question therefore follows necessarily. If theology is answerable to truth grounded in divine self-disclosure, how is human reason to serve that truth? How can philosophy render its indispensable ministry without becoming either revelation’s master or revelation’s enemy?

That is the question of reason under the Word.
