Linguistic Gap Analysis
Linguistic Gap Analysis — 1 John (English → Japanese)
1. Purpose and Method
1 John reuses a smaller core vocabulary than Romans but drives it far harder — the letter is built on a handful of recurring words (ἀγάπη, φῶς, μένω, γινώσκω/οἶδα, πνεῦμα, κόσμος, γεννάω) repeated in tight, cumulative argument cycles rather than Romans’ more discursive theological exposition. This changes the shape of the translation risk: Romans’ risks are often distributed across many distinct terms; 1 John concentrates enormous doctrinal weight onto very few words, each reused dozens of times across all five chapters. A single mistranslated or under-anchored rendering of 愛, 光, or 神から生まれる propagates error through the entire letter, not just one passage.
This document works through the whole book, chapter by chapter where new load-bearing vocabulary appears, and produces four required deliverables:
- A doctrine vocabulary matrix — for each of the curriculum’s eight named doctrines, the available Japanese terms, their weaknesses, and the recommended handling strategy.
- Missing vocabulary vs. crowded semantic neighborhoods — where Japanese simply lacks a term (requiring paraphrase/compound construction) versus where a term exists but is already occupied by a competing religious or pop-culture concept (requiring “fencing,” i.e., explicit doctrinal boundary-marking).
- Transliteration vs. paraphrase decisions — a ruling, with rationale, for every candidate term in 1 John where this choice is live.
- A ranked list of the letter’s highest-risk ambiguities, prioritized for Phase 2 review routing and Step 17 doctrinal fidelity focus.
All findings here are consistent with, and extend, the baseline translation_memory.json and bible_term_registry.json. No baseline term is altered.
2. Full-Book Chapter Sweep (Coverage Confirmation)
| Chapter | New load-bearing vocabulary surfaced | Disposition |
|---|---|---|
| 1 John 1 | 光/闇 (light/darkness), 交わり (fellowship, God-ward sense), 罪 (sin, intensified by 告白 pairing), 告白する (confess sin), 赦す/赦し (forgive), きよめる (cleanse), いのちの言葉 (Word of Life), 歩む (walk), 喜び (joy) | Fully analyzed below (§3, §4) |
| 1 John 2 | 弁護者 (advocate), なだめの供え物 (propitiation), 命令 (commandment), 反キリスト (antichrist), 油そそぎ (anointing), とどまる (abide), 子どもたちよ (little children address), 義/不義 intensified (righteous/unrighteous), 偽り者 (liar), confess_christ variant of 告白する | Fully analyzed below |
| 1 John 3 | 神の子どもたち (children of God) vs. 神の子 (Son of God) fencing, 神から生まれる (born of God), 種 (seed), 悪魔 (devil), カイン (Cain), 兄弟 (brother), 罪を行う／義を行う (practice sin/righteousness), 確信 (confidence) | Fully analyzed below |
| 1 John 4 | Core passage. 愛 (love) at maximum density, 神 thesis statements (“God is love,” 4:8,16), なだめの供え物 recap (4:10), 霊を試す (test the spirits, 4:1), 真理の霊／迷わしの霊 (spirit of truth/error, 4:6), 反キリスト recap (4:3), confess_christ_come_in_flesh (4:2-3), ひとり子 (only begotten, 4:9), 救い主 (savior, 4:14), 世 recap (4:1,3-5,9,14,17), 確信 recap (4:17) | Fully analyzed below — this chapter carries the single highest concentration of Critical-tier terms in the letter |
| 1 John 5 | 勝つ／打ち勝つ／勝利 (overcome/victory), 信仰 tied to overcoming, 証し／証言する (testimony), 水と血 (water and blood, incl. Comma Johanneum note), 死に至る罪 (sin unto death), 偶像 (idols), 永遠のいのち recap and thesis statement (5:13), 神から生まれる recap (5:1,4,18) | Fully analyzed below |
No chapter is without load-bearing content; all five chapters of 1 John are covered above. There is no “reviewed, no new terms” chapter in this short, densely doctrinal letter — every chapter contributes to at least one of the eight named doctrines.
3. Doctrine Vocabulary Matrix
For each of the curriculum’s eight named doctrines: the Japanese terms available, their specific weaknesses for this letter’s usage, and the recommended handling strategy.
3.1 God is Light and God is Love
| Available term | Japanese | Weakness | Recommended strategy |
|---|---|---|---|
| God | 神 (baseline, Critical) | Generic Shinto kami-class noun; especially acute risk here because 1:5 and 4:8/16 are essence statements (“God IS X”), not merely descriptive ones — a bare 神 risks “a kami is light/is love,” one deity’s attribute among many, rather than an exclusive claim about the sole true God’s nature | Mandatory 唯一のまことの神 qualifier at both thesis statements (1:5; 4:8,16), not just at first occurrence generally — treat each thesis statement as its own “first occurrence” for qualifier purposes |
| light | 光 (NEW, Critical) | No lexical alternative exists; dense competing associations with Amaterasu solar-imperial mythology and Amida Buddha (“Immeasurable Light,” Pure Land devotion) | Immediate doctrinal anchoring at 1:5, parallel in method to the baseline’s 神の国 handling — state plainly what “God is light” means (moral purity, self-revelation) before any devotional or metaphorical extension |
| love | 愛 (NEW, Critical) | Secular default = romantic/idol-fandom attachment; Buddhist-inflected default = craving/attachment (愛着) to be extinguished — the doctrinal inverse of 4:8’s claim | Explicit re-definition at every occurrence in the core passage (4:7-21), not just first occurrence — this is the single highest-density doctrinal term in the curriculum and cannot rely on one anchoring note to carry 15 verses |
| darkness | 闇 (NEW, Medium) | Lower risk than 光, but must stay visibly paired with 光 or the light/darkness dualism collapses into generic 悪 | Always translate as a matched pair with 光 in 1:5-7; 2:8-11 |
Overall doctrine risk: Critical. This is the doctrine most exposed to Japan’s dominant religious traditions simultaneously (Shinto solar mythology AND Buddhist Pure Land devotion AND secular romantic-love culture), making it the single highest-stakes doctrine in the curriculum for fencing work.
3.2 Fellowship with God and One Another
| Available term | Japanese | Weakness | Recommended strategy |
|---|---|---|---|
| fellowship | 交わり (baseline, Low in Romans → elevated Medium-High here) | Risks collapse into 仲間意識 (in-group harmony feeling, wa-culture) unless the vertical dimension (fellowship with God himself, 1:3) is kept explicit | Always render 1:3, 6, 7 with an explicit God-ward object stated in surrounding text, not left implicit as it can be in casual English |
| abide/remain | とどまる (NEW, Medium) | Core sense is physical/spatial (“stay at a place”); mutual, relational indwelling is a semantic extension Japanese does not supply automatically | Build cumulatively: first occurrence (2:6) should carry a short gloss; later occurrences (2:24, 27-28; 3:24; 4:12-16) should reinforce rather than re-explain from scratch |
| know (relational) | 知る／わかる (NEW, Medium) | Japanese lacks a clean structural parallel to Greek’s γινώσκω/οἶδα relational-vs-factual distinction | Translator notes at key clustered occurrences (2:3-5,29; 3:19-24; 4:2-8,13-16) rather than a fixed one-to-one lexical mapping |
Overall doctrine risk: Medium-High. Not a false-concept collision risk on the scale of §3.1, but a genuine structural-gap risk: Japanese simply does not pre-package this doctrine’s relational depth the way Greek’s vocabulary does.
3.3 Confession and Forgiveness of Sin
| Available term | Japanese | Weakness | Recommended strategy |
|---|---|---|---|
| sin | 罪 (baseline, High) | Guilt-before-God vs. shame/meiwaku risk, now compounded by pairing with 告白 | Reuse baseline exactly; reinforce guilt-before-a-personal-God framing at 1:8-10 |
| confess (sin) | 告白する (NEW, Medium) | Dominant everyday association is romantic confession of feelings (a stock anime/drama scene) | Explicit reframing note at 1:9, especially for younger/pop-culture-immersed readers |
| forgive/forgiveness | 赦す／赦し (NEW, High) | Must not collapse into interpersonal 許す (“letting go”) without the forensic, God-ward removal-of-guilt sense | Consistently pair with “cleanse” (きよめる) and “blood” (1:7,9) to keep the atonement-basis explicit |
| cleanse | きよめる (NEW, Medium) | Risk of conflation with Shinto ritual purification (禊/お祓い), which removes ceremonial pollution, not moral guilt | Distinguish explicitly, parallel to baseline’s 聖い vs. 清らか note |
| advocate | 弁護者 (NEW, High) | Same Greek word (παράκλητος) names a different referent (the Spirit) in John’s Gospel; risk of confusing two paraclete figures | Reserve 助け主 exclusively for the Spirit’s Gospel-of-John role; use 弁護者 exclusively for Christ’s 1 John 2:1 role, with an explicit note distinguishing the two |
| propitiation | なだめの供え物 (NEW, Critical) | なだめる is the live folk-religious verb for appeasing a vengeful spirit (祟り); risks a reluctant-deity picture | Never present without 4:10’s “God himself sent” framing attached in the same teaching unit |
Overall doctrine risk: Critical. The compounding of 罪’s guilt/shame ambiguity with 告白’s romantic-confession default and なだめ’s appeasement-of-a-hostile-spirit default makes this the doctrine with the most distinct, independent collision points (four separate terms each needing separate fencing), even though no single term here is as globally saturating as 愛 or 光.
3.4 Love for the Brethren as Evidence of New Birth
| Available term | Japanese | Weakness | Recommended strategy |
|---|---|---|---|
| love | 愛 (as §3.1) | Same collision, now applied behaviorally/ethically rather than as a divine-essence statement | Consistent term; teaching emphasis shifts from “what love IS” (ch. 4) to “what love DOES” (ch. 3) |
| brother | 兄弟 (NEW, Low) | Skews toward literal biological sibling in ordinary usage | Brief inclusive clarification (“brothers and sisters of the household of faith”) at first extended use (2:9) |
| children of God | 神の子どもたち (NEW, High) | Must not collapse into or blend with 神の子 (reserved for Christ) | Enforce absolute lexical separation from 神の子 in every occurrence; see §4.2 fencing entry |
| born of God | 神から生まれる (NEW, Critical) | Competing idiom 生まれ変わる is the standard phrase of Japan’s isekai reincarnation-fantasy genre; 輪廻転生 is a live Buddhist concept | Teach explicitly as unique, non-repeatable, Spirit-wrought — never cyclical, never “into a new world” |
| righteousness (behavioral use) | 義 (baseline, Critical) | Baseline’s Bushido-virtue risk is more acute here than in Romans because 3:7,10 use 義 as visible ethical evidence, exactly the register in which Bushido virtue also operates | Retain baseline’s distinguishing note at every behavioral (not merely forensic) occurrence in ch. 3 |
Overall doctrine risk: Critical. This doctrine sits at the intersection of the letter’s two highest-risk terms (愛 and 神から生まれる) plus an intensified version of the baseline’s 義 risk — three independently Critical-tier collision points converging on one doctrine.
3.5 The Incarnation and Antichrist
| Available term | Japanese | Weakness | Recommended strategy |
|---|---|---|---|
| incarnation (doctrine label) | 受肉 (baseline, Critical) | Baseline forbids 化身/権化; 1 John raises the stakes because denying this doctrine IS the letter’s own definition of the antichrist spirit (4:3) | Never soften toward “manifestation” language under any circumstance in this letter |
| confess Christ come in the flesh | イエス・キリストが肉をとって来られたことを告白する (NEW, Critical) | Compound phrase invented for this specific confessional formula; no shorter idiom exists that preserves both “confess” and “real flesh” | Retain full compound phrase; do not abbreviate to 受肉 alone when the text specifically foregrounds the confessional act, not just the doctrine |
| antichrist | 反キリスト (NEW, High) | Known in Japan mainly as a Western horror/apocalyptic villain trope | Anchor explicitly to the letter’s own definition (denial of the incarnation, 2:22; 4:3), not the pop-culture end-times-monster image |
| only begotten/unique Son | ひとり子 (NEW, Critical) | Must stay distinct from 神の子どもたち; avoid 長男 (implies birth order) | Reserve exclusively for Christ; never use for believers even loosely |
| Son of God | 神の子 (baseline, Critical) | Baseline’s arahitogami risk is joined here by a second, opposite-direction risk: dilution if confused with plural 神の子どもたち | Enforce both boundaries simultaneously — see §4.2 |
Overall doctrine risk: Critical. This is the doctrine 1 John itself treats as make-or-break (2:22-23; 4:2-3) — the letter names its own heresy and ties it directly to Christology vocabulary already flagged Critical in the baseline.
3.6 Assurance of Salvation and Eternal Life
| Available term | Japanese | Weakness | Recommended strategy |
|---|---|---|---|
| eternal life | 永遠のいのち (NEW, Critical) | Risk of drifting toward a future-reward or blessed-afterlife-realm reading (極楽往生-adjacent) | Anchor to 5:11-13’s present possession through the Son framing; this is the letter’s own stated purpose verse |
| savior | 救い主 (NEW, Critical) | ヒーロー (pop-culture “hero”) framing loses exclusivity | Retain exclusive personal-Redeemer sense; never substitute a generic rescuer/hero term |
| confidence | 確信 (NEW, Medium) | Risk of collapsing into generic secular self-help optimism | Tie explicitly to the objective basis (Christ’s finished work, God’s prior love), not subjective feeling |
| testimony | 証し／証言する (NEW, Medium) | Double sense: legal/eyewitness vs. subjective personal impression | Clarify context as courtroom-style eyewitness/divine testimony, not mere personal opinion |
| Word of Life | いのちの言葉 (NEW, Medium) | Risk of absorption into generic Japanese motivational-quote culture (心に響く言葉) | Anchor explicitly to the person of the incarnate Christ (1:1-3) |
Overall doctrine risk: Critical, driven primarily by 永遠のいのち’s proximity to Pure Land afterlife concepts and the doctrine’s status as the letter’s explicitly stated purpose (5:13).
3.7 Overcoming the World
| Available term | Japanese | Weakness | Recommended strategy |
|---|---|---|---|
| world (moral sense) | 世 (NEW, High) | Competing Buddhist framework: 現世/無常 (impermanent world to be transcended via detachment) vs. 1 John’s morally rebellious system to be actively resisted | Consistently pair with “doing the will of God” (2:17) as the positive contrast, not detachment/transcendence |
| overcome/victory | 勝つ／打ち勝つ／勝利 (NEW, High) | Japan’s competitive exam/career culture risks framing this as effort-earned achievement | Tie explicitly to “born of God” (5:1,4) as the enabling prior cause, not a self-generated competitive win |
| faith | 信仰 (baseline, High) | 1 John’s tight faith-overcoming linkage (5:4-5) sharpens baseline’s syncretism risk with a secondary competitive-effort risk | Faith is the means of receiving an already-secured victory, not the exertion producing it |
Overall doctrine risk: High. Structurally similar to the baseline’s “election” competitive-selection risk, now applied to an entire doctrine rather than one term.
3.8 Testing the Spirits
| Available term | Japanese | Weakness | Recommended strategy |
|---|---|---|---|
| test the spirits | 霊を試す (NEW, Critical) | The ONE place in the letter where bare 霊 (without 聖) is doctrinally correct — but this is precisely where Japan’s animistic worldview (ancestral spirits, yōkai, itako mediums) is most vividly activated | Always pair with the letter’s own confessional test (4:2-3) in the same teaching unit; never leave 霊を試す standing alone as a general “spiritual discernment” exhortation |
| spirit of truth/error | 真理の霊／迷わしの霊 (NEW, High) | “Spirit of truth” risks being mechanically read as a bare restatement of 聖霊 | Clarify this is a category label for a type of source, discerned by doctrinal content, not personal identity restatement |
| Holy Spirit | 聖霊 (baseline, Critical) | 3:24 and 4:13 omit the Greek ἅγιον qualifier, yet 聖霊 must still be supplied | Reuse baseline exactly; never render bare 霊 for the Trinity-Person referent |
Overall doctrine risk: Critical. This doctrine contains the single most structurally unusual case in the entire curriculum: the correct doctrinal choice (bare 霊 at 4:1) runs directly against the pattern established everywhere else in both the baseline and this glossary (always supply 聖霊). This inversion itself is a distinct risk requiring explicit callout — see §6, Rank 2.
4. Missing Vocabulary vs. Crowded Semantic Neighborhoods
4.1 Missing Vocabulary (genuine lexical gaps requiring paraphrase/compound construction)
These are concepts for which Japanese has no existing single word carrying the needed sense — the gap is structural, not competitive, and the strategy is compound-phrase construction rather than fencing an existing word.
| Concept | Gap | Constructed solution | Rationale |
|---|---|---|---|
| propitiation (ἱλασμός) | No Japanese noun combines “atoning sacrifice” + “appeasement” + “God-initiated” in one word | なだめの供え物 (compound: “placating offering”) | Closest available compound; requires mandatory 4:10 framing attachment (see §3.3) |
| confess Christ come in the flesh (ὁμολογεῖ … ἐν σαρκὶ ἐληλυθότα) | No single verb or short idiom captures both “publicly affirm” and “real, permanent embodiment” together | イエス・キリストが肉をとって来られたことを告白する (full descriptive clause) | The letter’s own defining confessional formula; abbreviation would lose either the confessional-act sense or the real-flesh sense |
| born of God (γεννάω ἐκ τοῦ θεοῦ) | No neutral Japanese term for “spiritual birth” that is not already claimed by a competing framework (see §4.2) | 神から生まれる (plain compound, avoiding 生まれ変わる) | Constructed to explicitly avoid the isekai/reincarnation idiom already in wide secular use |
| obedience/commandment as personal divine charge rather than social-harmony conformity | Japanese vocabulary for “must-do” defaults toward social-obligation register | 命令 retained, with explicit “from him” (4:21) framing reinforced in teaching | Not a new word but a required framing supplement; genuine gap is in the register, not the lexicon |
| water and blood as joint testimony (5:6,8) | No idiomatic Japanese legal/testimonial phrase combines these two referents naturally; the phrase is a transliteral rendering of a debated Greek construction | 水と血 (literal), presented with interpretive options rather than a forced resolution | Genuine textual ambiguity in the source itself; Japanese need not (and should not) resolve what the Greek leaves open |
4.2 Crowded Semantic Neighborhoods Needing Active Fencing
These are concepts for which a perfectly good Japanese word already exists and is in wide use for a different, competing concept — the risk is not blankness but active collision, requiring an explicit doctrinal fence at every occurrence, not just first occurrence.
| Term | Existing competing occupant(s) of the semantic space | Fencing strategy |
|---|---|---|
| 愛 (love) | (1) 恋愛/romantic attachment; (2) 愛着/Buddhist craving-attachment (root of suffering) | Fence at every occurrence in ch. 4, not just first: state that this is willed, self-giving love sourced in God’s nature, opposite in direction from craving |
| 光 (light) | (1) Amaterasu solar-imperial mythology; (2) Amida Buddha “Immeasurable Light” Pure Land devotion | Fence immediately at 1:5 with explicit doctrinal statement before any further metaphorical use |
| 神 (God) — thesis statements | The generic Shinto multi-kami category | Fence at both 1:5 and 4:8/16 with 唯一のまことの神, treating each as a separate first-occurrence event |
| 神の子 (Son of God) vs. 神の子どもたち (children of God) | Risk runs in BOTH directions: (a) confusing believers with Christ’s unique Sonship; (b) diluting Christ’s uniqueness by loose “God’s child” language | Fence with a standing cross-reference rule: 神の子 = Christ exclusively (singular, unique); 神の子どもたち = believers only (always plural, always distinct root metaphor — birth, not begetting) |
| 神から生まれる (born of God) | Isekai “reborn into a new world” genre convention; 輪廻転生 Buddhist reincarnation | Fence by explicit contrast: non-repeatable, no new “world,” permanent identity change, not a narrative reset |
| 世 (world) | 現世／無常 — Buddhist impermanence, a realm to be transcended via detachment | Fence by contrasting with “doing the will of God” (2:17) — active resistance, not passive detachment |
| 告白する (confess) | Romantic confession-of-feelings idiom (kokuhaku), a fixture of Japanese youth media | Fence separately for each of the two objects: sin (1:9) vs. Christ’s identity (2:23; 4:2-3,15; 5:1) — same word, two distinct doctrinal fences, doctrinally higher-stakes fence required for the Christological object |
| なだめの供え物 (propitiation) | 祟り-appeasement folk-religious framework (placating an angry spirit) | Fence by mandatory pairing with 4:10’s God-initiated-love framing every time it appears |
| 悪魔 (devil) | Anime/manga/gaming fictional-villain trope | Fence by restoring cosmic-evil, personal-agent weight in teaching, parallel to baseline’s 復活 dilution-repair pattern |
| 霊 (bare, at “test the spirits” only) | Animistic folk-spirit worldview (ancestral spirits, yōkai, itako mediums) | Fence by mandatory pairing with the confessional test of 4:2-3 in the same teaching unit — this is the one context-specific exception to the “always supply 聖霊” rule and must never be generalized beyond 4:1 |
| 偶像 (idols) | Butsudan (Buddhist ancestor altars), kamidana (Shinto household shrines), omamori/ofuda (amulets/talismans) as ordinary, often unremarked household objects | Fence pastorally and non-confrontationally; distinguish idolatrous worship from cultural/family objects without implying blanket condemnation of relatives’ households |
| 義 (righteousness), behavioral sense | Bushido rectitude/moral-courage virtue (Nitobe) | Fence at every behavioral occurrence in ch. 3 (not only forensic occurrences as in Romans) — 1 John’s ethical usage sits closer to the Bushido register than Romans’ primarily forensic usage did |
5. Transliteration vs. Paraphrase Decisions
| Term | Decision | Rationale |
|---|---|---|
| Antichrist (ἀντίχριστος) | Transliteration-based compound: 反キリスト | No native Japanese concept-word exists; borrowing the established キリスト transliteration and prefixing 反 (“anti-/counter-”) is transparent and avoids inventing a novel term that would itself require separate explanation |
| Christ / Messiah | Transliteration (baseline): キリスト | Reuse baseline exactly; no change for 1 John |
| Amen / Hallelujah (where they occur in surrounding liturgical material, not in 1 John’s body text itself) | Transliteration (baseline): アーメン, ハレルヤ | No occurrence within 1 John’s text itself, but retained per baseline for any liturgical framing material accompanying the curriculum |
| Cain | Transliteration: カイン | Proper name; standard Shinkaiyaku form, requires accompanying OT narrative gloss given near-zero OT literacy |
| propitiation (ἱλασμός) | Paraphrase/compound: なだめの供え物, not a transliteration | No transliteration tradition exists for this term in Japanese theological vocabulary (unlike, e.g., キリスト); a constructed compound is the only viable path, mandatorily fenced (§4.2) |
| Abba (cf. baseline, not present in 1 John but relevant methodologically) | N/A for this letter — 1 John does not use this Aramaic term | Noted for consistency; no action needed |
| paraclete-derived “advocate” (παράκλητος at 2:1) | Paraphrase: 弁護者 (legal-advocate sense), not a transliteration and not the Gospel-of-John’s 助け主 | Two distinct referents (Christ here; the Spirit in John’s Gospel) sharing one Greek word require two distinct Japanese paraphrases rather than one transliterated umbrella term |
| monogenēs (μονογενής, “only begotten”) | Paraphrase: ひとり子 | Established Japanese theological rendering; no transliteration tradition, and none needed — ひとり子 already carries the required uniqueness sense once fenced against 長男 |
| kosmos in its moral-system sense | Paraphrase using existing word: 世 (not 世界, not a new coinage) | 世 already carries the needed “age/moral-order” connotation in Japanese Buddhist-literary vocabulary generally; the task is fencing (§4.2), not constructing a new term |
| gennaō ek tou theou (“born of God”) | Paraphrase, deliberately avoiding the nearest idiomatic transliteration-adjacent option (生まれ変わる) | The nearest natural Japanese phrase is doctrinally contaminated by isekai/reincarnation associations; a flatter, less idiomatic compound (神から生まれる) is deliberately chosen over the more fluent-sounding alternative specifically to avoid that contamination — fluency is sacrificed for doctrinal safety here |
General ruling for this curriculum: transliteration is reserved for (a) proper names and (b) terms with zero viable native-vocabulary candidate and an already-established Japanese Christian transliteration tradition (キリスト, アーメン). Every other new term in 1 John is handled by paraphrase/compound construction using existing native vocabulary, because 1 John’s key concepts (love, light, birth, world, spirit) all have real Japanese words available — the risk is competitive occupation of those words by other frameworks, not absence of vocabulary. This is a materially different balance than some curricula might show, and it shifts the primary Phase 2 burden toward fencing existing words rather than explaining foreign loanwords.
6. Ranked List of Highest-Risk Ambiguities
Ranked by combined severity (doctrinal centrality × collision strength × frequency of occurrence in the core passage and letter as a whole):
-
愛 (love) — God’s essential nature vs. romantic attachment/Buddhist craving. The core passage (4:7-21) uses this word roughly 25+ times in 15 verses; any drift toward either competing sense at any single occurrence corrupts the letter’s central thesis. Highest-frequency, highest-centrality, dual-collision term in the entire curriculum.
-
霊を試す (test the spirits) — the one mandated exception to the “always supply 聖霊” rule. This is uniquely dangerous precisely because it inverts the pattern translators and reviewers will have internalized from every other Spirit-related term in both the baseline and this glossary. A reviewer applying the general rule mechanically will “correct” this to 聖霊 and thereby destroy 4:1’s actual meaning (a plural, mixed-referent field including false spirits). Flagged as the single highest structural-error risk for Phase 2 automated or careless human correction.
-
光 (light) — dual mythological/devotional collision (Amaterasu + Amida). Unlike 愛, this term faces two simultaneously live competing frameworks from Japan’s two dominant religious traditions at once, a doubling not seen elsewhere in the glossary.
-
神から生まれる (born of God) vs. 生まれ変わる (isekai/reincarnation idiom). The doctrinally safe rendering is the less fluent, less idiomatic Japanese phrase — meaning natural translator/reviewer instinct toward smoother prose runs directly against doctrinal safety. High risk of well-intentioned “improvement” back toward the contaminated idiom during later editing passes.
-
神の子 vs. 神の子どもたち — bidirectional Sonship dilution. Unlike most baseline Critical terms, which face a single directional risk, this pair faces collision risk from both directions simultaneously (over-including believers into Christ’s unique Sonship, or under-crediting believers’ real family status) and requires the reviewer to check two related but visually similar strings against each other, not just one string against a forbidden list.
-
告白する for both sin-confession and Christ-confession. Identical Japanese word, doctrinally unequal stakes depending on object — high risk of applying uniform (lower) review scrutiny to both simply because the lexical form is identical, when the Christological object (2:23; 4:2-3,15; 5:1) requires theologian-level review that the sin-confession object (1:9) may not always need.
-
なだめの供え物 (propitiation) — reluctant-deity risk. Severe if the mandatory 4:10 pairing is dropped in any abbreviated teaching context (e.g., a summary slide, a short devotional excerpt) that quotes 2:2 or 4:10’s noun without its surrounding sentence.
-
義 (righteousness) in behavioral/ethical use (ch. 3) — heightened Bushido-virtue collision versus Romans’ primarily forensic use. The baseline’s existing distinguishing note was written primarily for forensic contexts; 1 John’s ethical-evidence usage sits closer to the competing Bushido register and needs the note reinforced, not merely inherited.
-
世 (world) — active-rebellion-to-be-overcome vs. impermanent-realm-to-be-transcended. Risk is subtler than most entries above because both framings sound superficially similar in casual teaching language (“this passing world”) even though their theological postures (resist vs. detach) are opposite.
-
勝つ／勝利 (overcome/victory) — competitive-achievement reframing. Risk compounds with faith (信仰) in 5:4-5; Japan’s exam/career-competition culture is a strong enough cultural undertow that even correctly glossed teaching material may be heard through this lens by default without active countervailing framing.
-
偶像 (idols) — practical/pastoral rather than purely lexical risk. Lexically low-risk (偶像 is not contested vocabulary), but pastorally high-stakes given the ubiquity of butsudan/kamidana/omamori in ordinary Japanese family life, including believers’ own extended families; misapplied teaching risk is social/relational, not merely doctrinal.
-
知る／わかる (know) — structural gap, not collision. Lower ranked than the above because the risk is imprecision/flattening rather than active doctrinal corruption, but its very high frequency across the letter’s closing assurance section (5:13-20) means cumulative imprecision could still meaningfully blur the letter’s rhetorical certainty.
7. Summary and Handoff Notes
1 John’s translation-risk profile differs from Romans’ in a specific and important way: Romans’ highest risks were concentrated in technical theological vocabulary (justification, sanctification, propitiation-adjacent legal terms) that secular readers simply lack any prior framework for. 1 John’s highest risks are concentrated instead in ordinary, everyday Japanese words (愛, 光, 世, 告白する) that readers already have strong, well-formed — and doctrinally competing — associations for. This means the Phase 2 review burden for 1 John should weight fencing existing vocabulary more heavily than explaining unfamiliar vocabulary, the inverse of Romans’ predominant pattern. All eight named doctrines in this curriculum register Critical or High overall risk except “Fellowship with God and One Another” (Medium-High), a notably higher risk concentration than the baseline Romans package showed across its sixteen chapters. This finding should be carried forward into 07_semantic_analysis.md and 11_doctrine_analysis.md, and should inform Step 17’s reviewer-routing weight toward native-speaker cultural-fencing review in addition to (not instead of) theologian doctrinal review.
