Working definition
Doctrine is a formulated teaching authorized to some degree within a community. Doctrinal development traces changes in vocabulary, problem framing, councils, commentaries, institutions, and dissent, allowing continuity claims and historical transformation to coexist as separately attributed propositions.
Questions this method asks
- When and where was the formulation attested?
- What problem or dispute shaped it?
- Which communities accept or reject it?
Evidence inputs
- Dated formulations and decisions
- Commentaries and controversy records
- Institutional reception and practice
Method
- Version each formulation.
- Map dependencies and disputes.
- Distinguish insider continuity claims from historical description.
What it can establish
- When a formulation is documented
- How positions relate and change
What it cannot establish
- That development is corruption or progress
- The divine truth of the resulting doctrine
Interpretive risks
- Presentism
- Treating official settlement as unanimous belief
Mathematical connection
Formal structure without validity transfer
Formulation-change detection
Flag shifts in vocabulary or proposition frequency for human historical review.
Inputs
- Dated corpus
- Declared text features
- Segmentation assumptions
Outputs
- Candidate change points
- Uncertainty intervals
- Passages for review
Limit: A statistical shift is not automatically a doctrinal rupture, and continuity can persist through changed vocabulary.
Methodology sources
- [1]TEI P5 Chapter 13: Critical Apparatus · Text Encoding Initiative Consortium
Establishes: A formal vocabulary for recording textual witnesses, variant readings, apparatus entries, and the relationship between an edited text and its manuscript, print, translation, or quotation evidence.
Boundary: A critical apparatus documents variation and editorial judgment. It cannot recover unattested wording with certainty or convert a reconstructed reading into a theological or historical fact.
- [2]Teacher’s Guides and Primary Source Analysis Tool · Library of Congress
Establishes: A source-analysis workflow that distinguishes observation, reflection, questioning, format, authorship, context, and further investigation across manuscripts, oral histories, printed texts, images, and other primary materials.
Boundary: Primary-source analysis establishes what a surviving artifact can support in context; it does not make the artifact complete, unbiased, representative, or factually correct merely because it is old.
