Executive Summary: Joel (English → French)

Why it matters

Joel is this pipeline’s first Old Testament, Hebrew-source curriculum in French, and it introduces a distinct risk profile the Romans baseline does not cover: the tetragrammaton (YHWH), the book’s organizing “Day of the Lord” theme, and an OT repentance vocabulary (shuv) that collides head-on with entrenched French Catholic liturgical and sacramental usage. Get the naming conventions wrong here and the curriculum either produces a doctrinally false statement (Joel’s Day of the LORD read as Sunday worship) or silently erases the Christological bridge Paul builds in Romans 10:13 — the exact cross-curricular link this project exists to preserve.

Key findings

• Full-book coverage confirmed. All four French/Hebrew chapters (Joël 1-4, corresponding to English Joel 1-3) carry doctrinally load-bearing vocabulary; no chapter is theologically inert or silently skipped.
• Two new Critical naming conventions govern the entire book: the tetragrammaton renders as “l’Éternel” (never “Seigneur”), and “the Day of the LORD” renders as “le jour de l’Éternel” (never “le jour du Seigneur,” France’s fixed liturgical name for Sunday). These two decisions are structurally linked and must be enforced as a single non-negotiable rule, not per-verse style choices.
• 20 doctrines identified for this curriculum (5 curriculum-designated plus 15 supporting sub-doctrines), of which 4 are Critical and 5 are High risk — 9 total requiring mandatory human theologian review, matching doctrine_risk_registry.json’s routing totals exactly. A further 9 require native speaker review; 2 are automated-review-only.
• 17 individual glossary terms are Critical or High risk (7 Critical, 10 High) out of 38 total terms tracked in the extended translation_memory.json — nearly double the term-level scrutiny density of the Romans baseline, driven by the OT-specific naming and repentance vocabulary this book introduces.
• The single highest-stakes translation decision in the whole language package occurs at Joël 3:5: this verse is quoted verbatim by both Peter (Acts 2:21) and Paul (Romans 10:13). Because Joel’s OT text requires “l’Éternel” while the Romans baseline requires “Seigneur” for the same underlying name, a mandatory bridging teaching note is the only mechanism that makes Paul’s Christological identification of Jesus with YHWH visible to French readers.

Risks

• Liturgical collision (Critical): “le jour du Seigneur” = Sunday in Catholic usage; any lapse into this phrase for Joel’s eschatological Day destroys the doctrine outright.
• Sacramental redirection (Critical): bare “se repentir”/“la repentance” risks implying priestly-mediated confession where Joel’s Hebrew text commands direct, unmediated return to God.
• Erased Pentecost typology (Critical): silently substituting “l’Esprit Saint” for the literal “mon Esprit” of Joël 3:1-2 would erase the OT grammar and the very typological move Peter himself makes at Pentecost, teaching a conclusion instead of the text that produces it.
• Colloquial register drift (High): “terrible” has drifted toward a positive intensifier in spoken French, risking an inadvertently celebratory reading of “the great and terrible Day of the LORD.”
• Cultural-literary collision (High): the “beat plowshares into swords” reversal (Joël 4:10) inverts the Isaiah 2:4/Micah 4:3 oracle inscribed on a well-known UN sculpture and cited throughout French peace discourse; unglossed, readers will assume translation error rather than deliberate prophetic irony.
• Doctrinal premature-collapse risk (High): rendering chesed as “grâce” would flatten a distinct OT covenant-formula concept into the NT’s Christ-centered charis, undermining the careful salvation-historical sequencing this project’s baseline already protects for Romans.

Opportunities

• Existing liturgical familiarity is an asset, not only a risk. Joël 2:12-18 is the appointed Ash Wednesday reading in the French Roman Lectionary; most French Catholics, even lapsed ones, have heard “Déchirez vos cœurs et non vos vêtements” read publicly. Lesson-writers can leverage this as a bridge into the book rather than starting from zero.
• Jewish teshuvah is the closest cross-tradition parallel found anywhere in this project’s comparative work, offering a rare opportunity for respectful, historically grounded interfaith framing notes around the Repentance and Return doctrine.
• The Joël 3:5 → Romans 10:13 bridge, done well, becomes a flagship cross-curricular teaching moment — demonstrating to learners moving between curricula exactly how this pipeline’s terminology discipline (distinct “l’Éternel”/“Seigneur” renderings, reconciled by explicit note) protects rather than obscures a text’s theological argument.

Recommended actions

1. Encode the “l’Éternel”-not-”Seigneur” and “le jour de l’Éternel”-not-”le jour du Seigneur” rules as an automated Phase 2 pre-validation check (not translator discretion), per the cross-cutting recommendation in 06_linguistic_gap_analysis.md Part 6.
2. Make the Joël 3:5 / Romans 10:13 bridging note mandatory and textually fixed (not paraphrased ad hoc) at every occurrence, per 12_ai_translation_requirements.md.
3. Route all 9 Critical/High-risk doctrines to human theologian review before any Phase 2 output is accepted as final; route the 9 Medium-risk doctrines to native speaker review.
4. Brief lesson-writers explicitly on the Ash Wednesday lectionary connection and the teshuvah parallel as constructive framing assets, while cautioning against implying priestly mediation is required by Joel’s own text.
5. Carry the finalized assets/translation_memory.json and assets/bible_term_registry.json (Joel-extended) forward as the enforced baseline for any future OT curriculum in this language, since several of this book’s naming-convention solutions (tetragrammaton handling, Day-of-the-Lord/Sunday collision) will recur in any future prophetic-book curriculum.
