Executive Summary — 1 Corinthians Japanese Language Package

Why it matters: 1 Corinthians is a doctrinally denser and pastorally more sensitive book than Romans for a Japanese audience — its core passage (15:1-11) anchors the resurrection, the single most secularly-diluted theological term in the language (復活), while the book’s practical chapters (idol meat, marriage, tongues, the Lord’s Supper) collide directly and structurally — not just superficially — with living Japanese household religious practice (butsudan, kamidana, itako mediumship, Buddhist memorial meals). Getting this package right determines whether Japanese learners receive Paul’s actual argument or a quietly reshaped, culturally-absorbed substitute.

Key findings

• 91 enforced terms now sit in the merged translation memory (36 inherited from the Romans baseline, exactly preserved, plus 55 new terms introduced by 1 Corinthians).
• 49 of those 91 terms (54%) are Critical or High risk and require mandatory human theologian review at every occurrence — up from the Romans baseline’s smaller Critical/High share, reflecting this book’s heavier concentration of culturally-collision-prone vocabulary (idol meat, demons, tongues, headship, love, the Lord’s Supper).
• 28 distinct doctrines are tracked for 1 Corinthians specifically (5 Critical, 16 High, 5 Medium, 2 Low); 21 of the 28 require human theologian review, 5 require native speaker review, and only 2 are automated-only.
• Combined with the Romans baseline’s 40 tracked doctrines, the two-book package now carries 68 total doctrine entries, of which 47 require theologian oversight — the single largest driver of Phase 2 review-routing workload in this Language Package to date.
• Two terms are judged to carry structural (not merely superficial) collision risk with living Japanese religious practice, making them the package’s highest-stakes translation decisions: 悪霊 (demon), which risks being filed alongside folk yūrei/yōkai rather than understood as personal beings opposing God; and 神殿 (temple), whose Shinto-shrine architectural sense is genuinely structurally parallel to Paul’s indwelling-Spirit theology and must be firmly anchored every time.
• 愛 (agapē love, ch. 13) carries the single highest cultural-defeat risk in the package: contemporary secular usage defaults to romantic love, and the chapter is a default wedding reading even for non-Christian couples — the translation must actively work against this reflex, not merely supply the correct word.
• 御霊のからだ (spiritual body, 15:35-58) and 復活 (resurrection, throughout ch.15) are the doctrinal load-bearing terms of the entire curriculum’s core passage; both run directly against the grain of available Japanese afterlife imagery (disembodied ancestral spirits, pop-culture “comeback” usage) and require active, sustained restoration of doctrinal weight rather than passive reliance on correct word choice.

Risks

• Silent kanji substitution: 知恵 (wisdom, correct) vs. 智慧 (Buddhist prajñā, incorrect) is a homophone risk invisible in speech and vulnerable to IME auto-conversion — mechanically identical to the baseline’s 預言/予言 risk but attached to the central “cross as wisdom” doctrine.
• Pastoral offense risk, bidirectional: drawing the idol-meat/ancestor-offering parallel (偶像, 偶像に献げられた肉) too directly risks accusing readers’ ordinary family piety of paganism; drawing it too loosely risks readers dismissing the whole doctrine as irrelevant ancient exotica.
• Genuine exegetical ambiguity: からだを見分ける (discerning the body, 11:29) has no single correct resolution among Christ’s sacrificial body / the church body / both — this must be flagged for review, never silently resolved by the AI system.
• Achievement-culture reinterpretation: 競技/冠 (athletic race/crown, 9:24-27) and 誇る (boasting, throughout) both risk being absorbed into Japan’s ganbaru merit-effort culture, quietly reintroducing a merit-earns-reward logic into a grace-saturated book.
• Mediumship conflation: 異言 (tongues, ch. 12, 14) risks being read through itako-style trance-mediumship folk phenomena rather than as Spirit-authored, speaker-controlled edifying speech.

Opportunities

• 家元 (iemoto) master-disciple transmission culture offers a genuinely strong, structurally apt teaching bridge for 15:1-3’s “delivered/received” tradition-transmission language — a rare case where an existing Japanese cultural framework strengthens rather than undermines the doctrine, provided the “esoteric technique” misreading is fenced.
• 秩序 (order in worship, ch. 14) is one of the lowest-risk, most intuitively bridged doctrines in either book, thanks to Japan’s strong cultural value on procedural correctness — a low-cost opportunity to build reader confidence before harder passages.
• 養子縁組 (adoption) and now 家元 transmission culture together demonstrate that this package’s most delicate collision risks (idol meat, demons, spiritual body) are matched by at least two genuinely constructive cultural bridges worth foregrounding in teaching materials rather than only flagging risks.

Recommended actions

1. Merge assets/translation_memory.json (v2) into the active Phase 2 enforcement pipeline before any 1 Corinthians segment translation begins; confirm all 55 new terms and inherited 36 baseline terms load correctly.
2. Prioritize human theologian review capacity toward chapter 15 (core passage) and the idol-meat/demon cluster (chs. 8, 10) first, given their combined Critical-tier weight and structural cultural-collision profile.
3. Add automated kanji-verification checks for 知恵/智慧 and 預言/予言 pairs to the Phase 2 pre-submission pipeline, per analysis/12_ai_translation_requirements.md’s validation table — this is a mechanically detectable risk class distinct from interpretive risk and should not consume theologian review bandwidth.
4. Brief all assigned theologians and native-speaker reviewers on the bidirectional pastoral sensitivity required for idol-meat material (chs. 8, 10) before routing begins, so framing decisions are consistent across reviewers rather than adjudicated ad hoc per segment.
5. Flag 1 Corinthians 11:29 (“discerning the body”) for dedicated theologian discussion prior to Phase 2 rather than resolving it segment-by-segment, given its genuine exegetical ambiguity.
