Model doctrinal development over time (Newman)

[JohnRDOrazio]

Context

John Henry Newman's theology of doctrinal development holds that doctrine is not static but unfolds organically over time. This has significant implications for how CMDDR models the relationship between documents across different historical periods.

Problem

The current table presents document types as timeless categories. Newman argues that doctrine develops historically, and a data model that cannot distinguish between contradiction and development, or between clarification and change, is structurally misleading.

Proposed Enrichment

The CMDDR data model should consider tracking:

• Historical states — how a teaching was formulated at different points in time
• Developmental notes — annotations on how a teaching evolved
• Criteria of authentic development — Newman's seven "notes" for distinguishing genuine development from corruption:
  1. Preservation of type
  2. Continuity of principles
  3. Power of assimilation
  4. Logical sequence
  5. Anticipation of its future
  6. Conservative action upon its past
  7. Chronic vigour

Additional fields to consider:

• stage_of_development — implicit, emerging, explicitly defined, dogmatized
• earlier_formulations — links to prior expressions of the same doctrine
• degree_of_clarity — how precisely the doctrine has been articulated

Impact on the Table

The README table could include a note acknowledging that document types and their authority may be understood differently across historical periods. The data model itself should support temporal layering.
