Positiones

Theses.

Stated the old way, as theses for disputation. Each one is defended somewhere in the work below.

  1. On formal systems

    No formal system interprets itself. Syntax does not yield semantics; a theory cannot, from within, select which of its many admissible models is the one it is about.

  2. On intelligibility

    Intelligibility is not produced, by minds, practices, or formal structures, but is a real, irreducible condition of determinability, presupposed by all three and reducible to none of them.

  3. On theological judgment

    The theologian of the cross calls the thing what it is. Christian grammar can be perfectly preserved while Christian reference is quietly relocated into an alien ontology, and grammar alone cannot detect the loss.

  4. On the present crisis

    Theological realism, semantic realism, and theophysical causation are the three conditions that make Lutheran proclamation intelligible as more than the church's self-description. Their erosion, not institutional decline, is the actual crisis.

Forma Optima, sed Nihil ad Materiam: Luther, Ockham, and the Arbiters of Trinitarian Inference

Essay, 2026 · first article in the Nova Lingua series

In the 1539 disputation Verbum caro factum est, Luther calls two Trinitarian syllogisms good, grants their premises, and denies their conclusions. The essay reads those theses against Ockham, Gregory of Rimini, d’Ailly, and Luther’s Erfurt teacher Usingen, who had argued over the very same syllogisms. Luther refuses to let either a scholastic repair or the Lateran decision settle the article: the form is philosophically excellent, but it has no jurisdiction over the matter.

  1. Forma Optima, sed Nihil ad Materiam: Luther, Ockham, and the Arbiters of Trinitarian Inference

    Luther's 1539 claim that a good syllogism can run from true premises to a false conclusion, read against Ockham, Gregory of Rimini, d'Ailly, and Usingen. The first of three or four Nova Lingua articles from current research.

    Published

  2. Is Luther’s Nova Lingua Intensionalist? Signification and the Propriety of Theological Speech

    The companion to Forma Optima. Five senses of "intension," each settled by a Luther text, with White, Cross, and Linde placed on a single grid and the author's own 1990 and 2002 readings corrected without being discarded.

    Published

  3. After the Kantian Settlement

    Four essays tracing how Kant's split between appearance and thing-in-itself took hold of modern Protestant theology, and a constructive case for getting reference back.

    In progress

  4. Theology under an Interpretation

    Tarski's model theory applied to how theology is read, through an admissible model class K(F).

    Third draft

  5. Formalization, Interpretation, and Theological Truth: What Modern Logic Teaches Theology

    What modern logic can and cannot settle for theology: consequence, model-theoretic underdetermination, reference, and nonclassical inference. Luther’s Trinitarian syllogisms become an exact test for Priest’s LP, and the Formula of Concord a confession that can be faithfully reconstructed even when no classical model satisfies it.

Disputationes Theologicae — opening

"Not with the victory of a method, but with the promised victory of the crucified and risen Logos … Truth lives."

Disputationes Theologicae — closing

Also forthcoming — Cascade Books, early 2027

"The questions animating this book arose before logic or graduate study, in the distance I felt between the plain world of my youth and the language I heard in church. On the farm, words named what I could see and handle; in church, they reached toward realities I could not see."

The Logic of Faith: Model Theory and the Grammar of Theological Truth — introduction

"Confusion is no mark of mystery, and equivocation does not honor transcendence. The end of theological reasoning is responsible witness to a subject we never master."

Disputatio

Test a claim.

A thesis is stated. Objections are raised. A response is owed. Press and hold to hear it.

Thesis

Christian grammar can be perfectly preserved while Christian reference is quietly relocated into an alien ontology.

  1. 1If the words are the same, the faith is the same.
  2. 2Meaning is use. Ask what the church does with the words, not what they point to.
  3. 3Talk of reference smuggles metaphysics back into theology.
Press and hold

The same sentences can be true in one world and idle in another.

Grammar alone cannot detect the loss.

So the theologian of the cross does the harder thing, and calls the thing what it is.
