Executive Summary — Galatians Language Package (Japanese)

Why it matters: Galatians is Paul’s most concentrated argument for justification by faith alone, built on a dense chain of covenant-history, freedom, and identity doctrines that collide with Japan’s religious landscape in more numerous and more severe ways than Romans did. The core passage (Galatians 2:15-21) compresses the letter’s entire thesis into seven verses containing a triple-repeated forensic verb, a Critical-risk union-with-Christ formula, and a false-friend translation trap — meaning the theological anchor of this curriculum is also its single highest-density risk zone. Getting this package right determines whether Japanese learners receive Paul’s actual argument or a domesticated, on-giri-compatible, achievement-flavored substitute.

Key findings:

• Galatians reuses 29 Critical/High/Medium/Low terms already locked in the Romans baseline (grace, faith, righteousness, justification, Son of God, Holy Spirit, God, covenant, etc.) — these carry over unmodified and must never be re-derived.
• Galatians introduces 48 new theological terms requiring fresh risk-tiering, of which 6 are Critical and 15 are High — nearly half the new vocabulary demands mandatory theologian review.
• Combined with baseline-inherited Critical/High terms relevant to this book, 39 total terms (15 Critical + 24 High) require absolute glossary enforcement with zero substitution tolerance.
• The doctrine layer tracks 24 distinct doctrines across all six chapters, of which 18 (8 Critical + 10 High) require mandatory human theologian review, 4 require native speaker review, and only 2 are automated-review-safe.
• One term — elemental spirits (στοιχεῖα τοῦ κόσμου, Gal 4:3, 9) — is deliberately left UNRESOLVED at Phase 1, forwarding two candidate renderings to theologian adjudication rather than risk validating Japan’s living animistic worldview as theologically real.
• Full six-chapter coverage is confirmed: every chapter contributes tracked doctrine or vocabulary, and no chapter was silently skipped (see 11_doctrine_analysis.md coverage table).

Risks:

• On-giri inversion risk (grace/law-merit doctrines): “Fallen from grace” (恵みから落ちる, Gal 5:4) is uniquely vulnerable to being read backwards — as failing to repay a favor — which would invert Paul’s actual point. This is the package’s single most dangerous mistranslation trap alongside the δωρεάν false-friend at 2:21 (恵みによって would exactly reverse “for nothing”).
• Bushido-義 collision at the letter’s rhetorical center: Galatians 2:16 triple-repeats the justification verb precisely to deny that righteousness is an achieved virtue — the exact sense the Bushido-honor-code word 義 otherwise carries in Japanese culture. A fencing failure here compromises the core passage’s thesis.
• Animistic/folk-religious collision cluster: curse (呪い vs. 祟り grudge-curses), idolatry (偶像礼拝 vs. butsudan/kamidana household practice), elemental spirits (vs. yaoyorozu no kami), sorcery (魔術 vs. active onmyoudo/fortune-telling culture), and fruit of the Spirit (御霊 vs. Shinto ancestral-spirit vocabulary) together form the highest concentration of syncretism risk in any language package produced to date for this curriculum library.
• Dilution risk cluster: 自由 (freedom → individualist autonomy), 肉 (flesh → literal meat), 新しい創造 (new creation → self-help “new me”), 約束 (promise → generic secular promise) each risk quiet meaning-loss even when the “correct” word is used, requiring active in-text restoration rather than passive reliance on context.
• Internal polysemy risk: 奴隷 (slave) must carry three distinct, even contradictory, senses (Paul’s willing submission, law/sin bondage, a transcended category) across the same short letter with zero native positive register to draw on.

Opportunities:

• Japan’s established adult-heir adoption custom (養子縁組) remains, as in Romans, a genuine cultural bridge for Adoption and Sonship — Galatians 4:5-7 can lean on this asset even more directly given its explicit redemption-then-adoption causal chain.
• Japan’s rice-farming heritage makes the sowing/reaping metaphor (6:7-9) and the yoke-of-slavery image (5:1) unusually low-risk, concrete, and teachable without cultural bridging.
• Japan’s inheritance-succession culture (相続, 家督) offers a strong natural bridge for the inheritance/heir vocabulary of chapters 3-4.
• The letter’s own argument structure (3:15-18) productively exploits rather than fights the ordinary commercial-contract sense of 契約 — a rare case where the baseline’s usual dilution caution becomes a deliberate asset instead of a liability.

Recommended actions:

1. Route all 18 Critical/High doctrines and all 21 Critical/High new terms through mandatory human theologian review before Phase 2 output is finalized, per doctrine_risk_registry.json and 08_core_glossary.md.
2. Do not permit Phase 2 automated processing to finalize a rendering for elemental spirits (Gal 4:3, 9) — enforce the unresolved-flag escalation rule in 12_ai_translation_requirements.md.
3. Require inline context-markers (not reliance on surrounding prose) for every occurrence of 奴隷, 肉, 義 in justification contexts, and 御霊 — Japanese lacks the morphological cues English uses to disambiguate these automatically.
4. Prioritize theologian + native-speaker joint review of the core passage (2:15-21) above all other segments, since it uniquely stacks the Bushido-義 collision, the on-giri/grace collision, and the Critical “crucified with Christ” formula in seven consecutive verses.
5. Carry the deliberate, documented exceptions (契約’s legal sense at 3:15-18; 御霊の実’s fixed idiom) forward into Phase 2 QA tooling as pre-approved, not as flagged inconsistencies requiring resolution.
