What it analyzes
Eight dimensions of doctrinal review — in a single report.
Doctrinal Soundness Score
A 1–5 scale grounded in historic Christian orthodoxy, calibrated across Trinitarian doctrine, Christology, soteriology, bibliology, and ecclesiology. Each score is backed by specific textual evidence.
Psychological Framework Detection
Scans for Internal Family Systems (IFS), the enneagram, Jungian archetypes, centering prayer, and therapeutic gospel language — with confidence scores and theological explanation for each.
Worldly Philosophy Analysis
Identifies Moralistic Therapeutic Deism, social justice misapplication, neo-Gnostic dualism, and prosperity theology — rated Subtle, Moderate, or Pervasive with direct quotations as evidence.
Source Reliability Assessment
Every cited author rated Reliable, Caution, or Problematic. Protects against endorsement by association — one of the most common pathways for false teaching to enter a congregation.
Hermeneutical Methodology
Flags eisegesis, allegory misuse, context stripping, and reader-response interpretation. Rates overall exegetical faithfulness and how the author treats Scripture as authority.
Confessional Alignment
Measures agreement with your chosen tradition — Reformed, Evangelical, Anglican, or your denomination's standards. Surfaces points of divergence explicitly so elders can make informed decisions.
Critical Alert System
CRITICAL, HIGH, MEDIUM, and LOW severity alerts. Each includes the specific passage that triggered it, a biblical counterpoint, and a recommended pastoral action.
Pastoral Recommendations
Prioritized guidance: use as-is, use with caveats, use excerpts only, or avoid. Each recommendation includes implementation guidance and what to watch for in follow-up content.
