One Sunday, one verse

Status: Anticipated · untested

Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

A thirteenth-century sermon opened with a thema, a scriptural verse chosen from the day's readings, from which the whole discourse was unfolded. In principle a preacher could pick any verse of the pericope; the conjecture is that the market for model sermons rapidly standardized the choice, so that each Sunday of the year converged on a single canonical thema verse whose share of all sermons for that Sunday grows decade by decade. The mechanism is the model-sermon economy itself: preachers bought collections, collections copied successful predecessors, and a verse that accumulated ready-made divisions and exempla became ever cheaper to preach on. If it holds, the free choice at the heart of the ars praedicandi collapsed into a de facto second lectionary — a canon within the canon, created by convenience.

Prediction clause (verbatim)

Primary clause: in Schneyer's repertory, for a majority of Sundays of the church year, the modal thema verse's share among catalogued sermons for that Sunday rises across the thirteenth century and exceeds 50% by 1300. Secondary: convergence is faster for Sundays whose pericopes are short (fewer candidate verses).

Kill-dataset (verbatim)

Schneyer's Repertorium der lateinischen Sermones des Mittelalters (thema and occasion fields across the eleven volumes).

Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior. Kills and priors are credited here, by name, as they come in.

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

Schneyer's repertory and Wegweiser catalogue themata by occasion, and the model-sermon economy is well studied, but per-Sunday convergence of thema choice measured decade by decade — the de facto second lectionary — is un-run.
