01 — Executive Summary: Joel (English → Mandarin)

Why it matters

Joel is short — three chapters — but doctrinally dense, and its core passage (2:28-32) is one of the most-cited Old Testament texts in the New Testament, quoted at length by Peter at Pentecost (Acts 2:17-21) and by Paul in Romans 10:13. Any Mandarin rendering of Joel is therefore not a standalone task: it is the load-bearing hinge between this curriculum and the already-shipped Romans Language Package. Getting the Spirit-outpouring and “calling on the name of the Lord” vocabulary wrong here would retroactively weaken the theological coherence of the Romans material already in production.

Key findings

• Full-book coverage confirmed. All three chapters were analyzed; no chapter was silently skipped. Chapter 1 (locust plague/lament) and Chapter 3 (judgment on the nations/final restoration) contribute substantial new vocabulary beyond the core passage.
• 21 distinct doctrines identified and risk-tiered: 5 Critical, 7 High, 8 Medium, 1 Low — requiring theologian review for 12 doctrines (57%) and native-speaker review for 8 (38%).
• 52 new Joel-specific terms added to translation memory, plus 11 baseline Romans terms inherited unmodified (God, Holy Spirit, Grace, Salvation, Called, Calling, Election, Prophet, Prophecy, Israel, Lord) because Joel’s doctrine directly extends or bridges into them.
• Term-level risk: of the 52 new terms, 5 are Critical and 8 are High risk — concentrated almost entirely in the core passage (2:28-32) and the repentance/judgment material (1:1–2:17).
• The single largest risk in the book is not lexical but a default-interpretive-framework risk: Mandarin readers possess a ready-made native explanation for agricultural disaster (天谴/天人感应, Han-Confucian cosmic ruler-virtue resonance) that requires zero teaching to activate — unlike Joel’s actual doctrine of personal covenant discipline, which requires active, repeated counter-teaching at every occurrence, not just careful word choice.
• Two items are formally unresolved and blocking for Phase 2: the exact standing CUV wording for “Valley of Decision” (3:14), and the exegetical resolution of a genuine MT/LXX textual divergence at 3:21 (“avenge their blood… not acquit”).

Risks

• Critical-tier collision risk concentrated in: 耶和华的日子 (Day of the LORD, vs. secular 末日/Buddhist 末法时代), 归向 (Return to God, vs. Buddhist 皈依 and the proverb 回头是岸), 浇灌 (Spirit poured out, vs. impersonal force/气/法力), and 求告耶和华的名 (Calling on the LORD’s name, vs. folk-religious petition verbs 求签/问卜/求神拜佛) — this last term is doctrinally load-bearing across BOTH the Joel and Romans curricula and must use an identical verb in both.
• High-tier collision risk in the locust-plague material (1:1–2:11), which is exposed to an unprompted native cosmological framework (天谴/天人感应) more aggressively than any Romans doctrine was exposed to a single competing framework — this requires standing, per-occurrence review, not one-time glossary fixes.
• Two production blockers: an unconfirmed proper-noun rendering (3:14) and an unresolved text-critical translation decision (3:21), both requiring Human Theologian sign-off before any Phase 2 segment touching those verses can proceed.
• Cross-curriculum consistency risk: if 求告 (call on) or 圣灵 (Holy Spirit) or 恩典 (grace) drift between how Joel and Romans render them, the pedagogical bridge from Joel 2:28-32 → Acts 2 → Romans 10:13 — the curriculum’s central argument — breaks for the learner.

Opportunities

• Joel 2:28-32’s Spirit-outpouring and universal-scope language (“all flesh,” sons and daughters, servants) gives this curriculum a natural, vivid on-ramp into the Romans baseline’s “Universal Scope of the Gospel” doctrine — the two curricula can be explicitly taught in sequence with shared vocabulary reinforcing each other.
• Joel’s concrete agricultural imagery (locusts, rain, grain, new wine) offers unusually vivid, non-abstract teaching material for a curriculum audience assumed to have low OT narrative literacy — this is a strength to be preserved, not abstracted away, in Phase 2 translation.
• The book’s tight judgment-repentance-restoration structure is well-suited to reinforcing, rather than merely repeating, the baseline’s grace-vs-merit (恩典 vs. 功德) distinction already established for Romans — Joel’s restoration material (2:18-27) gives a second, independent narrative occasion to teach the same non-negotiable distinction.

Recommended actions

1. Resolve the two blocking items (Valley of Decision wording; 3:21 exegetical decision) via Human Theologian review before any Phase 2 segment translation of Joel 3 begins.
2. Load both the Romans baseline and Joel-extension translation_memory.json and doctrine_risk_registry.json files together for every Joel Phase 2 session; treat verb consistency for 求告 (call on the Lord’s name) as a cross-curriculum non-negotiable, validated at every occurrence in both books.
3. Institute per-occurrence (not first-occurrence-only) Human Theologian review for the four locust terms in 1:1–2:11, given the demonstrated default-framework risk from Han-Confucian cosmic-resonance theory.
4. Carry all 21 Joel doctrines and their risk tiers forward into Phase 2 Step 17’s review-routing logic exactly as recorded in assets/doctrine_risk_registry.json (Joel), without modification, alongside the unmodified Romans baseline registry.
