Executive Summary: Ephesians (English → Spanish)

Why it matters

Ephesians extends the Romans Language Package into the most ecclesiologically and devotionally “occupied” theological territory this Spanish-language curriculum series has yet entered. Two brand-new phrases — “misterio” and “cuerpo de Cristo” — collide directly with load-bearing categories of everyday Catholic devotional practice (the Rosary’s mysteries, the sacraments, and the words spoken over the consecrated host at every Mass). Get these wrong, and the letter’s central claims — a hidden plan now fully revealed, and the church as Christ’s living body — will be silently reabsorbed into the very devotional frameworks Ephesians is not describing. The core passage, Ephesians 2:1-10, compresses the letter’s highest-stakes grace-versus-works argument into ten verses that must be rendered with surgical grammatical precision (a Greek perfect tense with no Spanish morphological equivalent) or the doctrine collapses toward the Tridentine merit-cooperation framework this Language Package exists to guard against.

Key findings

• 30 doctrines identified, spanning all 6 chapters with zero silent omissions; 8 Critical-risk and 11 High-risk doctrines require mandatory human theologian review — 19 of 30 doctrines total, the highest theologian-review concentration of any curriculum built on this baseline so far.
• 112 terms now populate the Ephesians translation_memory.json (39 inherited from Romans exactly, unchanged, plus 73 new entries), spanning Critical (9), High (25 total across inherited+new), Medium (~24), and Low (~13) tiers.
• Two entirely new Critical-tier lexical collisions not present in the Romans baseline: “misterio” (Rosary/sacramental devotional category) and “cuerpo de Cristo” (identical wording to the Eucharistic host formula spoken at every Catholic Mass) — the single highest-stakes new risk in this curriculum.
• The core passage’s perfect-passive construction, “por gracia sois salvos” (2:5, 8), has no Spanish morphological equivalent and must be fixed as a non-negotiable formula to prevent drift toward a durative, uncertain-outcome rendering.
• Spiritual warfare vocabulary (2:2; 3:10; 6:10-20) introduces the curriculum’s densest syncretism-risk cluster, with live collision potential against Espiritismo, Santería, and curanderismo folk-protective frameworks active across Latin America and the Caribbean.
• Household codes (5:21-33; 6:1-9) carry acute real-world pastoral stakes (documented patterns of coercive headship-submission readings; the historically distinct but easily conflated referents of first-century household slavery versus transatlantic chattel slavery).

Risks

• Highest risk: “cuerpo de Cristo” defaulting to the Eucharistic host referent for Catholic-background learners at every one of its five occurrences (1:23; 4:12, 16; 5:23, 30) without explicit, repeated disambiguation.
• Structural risk: “misterio” (five occurrences in chapter 3 alone) retaining a veiled, ongoing-devotional connotation rather than Ephesians’ “fully disclosed” sense.
• Grammatical risk: the 2:5/2:8 perfect-passive “saved” construction drifting durative, reinforcing folk-Catholic salvation-as-uncertain-lifelong-project framing.
• Causal-direction risk: 2:9-10’s identical Greek noun (ἔργα) for excluded “works” and included “good works” being flattened into a single undifferentiated concept, reintroducing merit-based salvation by accident.
• Conflation risk: the corporate “una nueva humanidad” (2:15) and individual “el nuevo hombre” (4:24) sharing overlapping natural Spanish vocabulary if not actively fenced apart in translation memory.
• Pastoral-safety risk: “someterse” (5:21-24) and “cabeza” (5:23) being taught or translated without their mandatory mutual-submission (5:21) and self-sacrificial-love (5:25) framing, given documented regional patterns of coercive authority.
• Syncretism risk: “principados y potestades,” “el príncipe de la potestad del aire,” and “las asechanzas del diablo” being absorbed into active Espiritismo/Santería spirit-hierarchy and protective-magic frameworks.

Opportunities

• Ephesians’ explicit “una nueva humanidad” and “unidad” language offers a strong pastoral bridge to real, present-day regional divisions (indigenous/Afro-descendant, Catholic/Evangelical/Pentecostal) — an opportunity to teach ancient Jew-Gentile reconciliation with immediate contemporary application.
• The armor-of-God passage (6:10-20), correctly fenced against folk-protective-magic alternatives, offers a compelling, culturally resonant teaching on sufficient, already-won spiritual security — directly relevant in regions affected by real spiritual-protection folk practices.
• The letter’s dense Trinitarian structure (1:3-14; 4:4-6) allows reinforcement of the baseline’s already-established Dios/Padre/Espíritu Santo/Cristo consistency, strengthening cross-curriculum vocabulary retention for learners studying both Romans and Ephesians.
• Explicit teaching notes on “misterio” and “cuerpo de Cristo” — necessary defensively — also create a natural opportunity to teach Ephesians’ own distinctive theology of revelation and church identity on its own terms, deepening doctrinal literacy rather than merely avoiding collision.

Recommended actions

1. Mandatory theologian review for all 8 Critical and 11 High doctrines (19 of 30 total) before any Phase 2 segment is marked approved, per the escalation rules in 12_ai_translation_requirements.md.
2. Fix and freeze the “por gracia sois salvos” formula, the “una nueva humanidad”/“el nuevo hombre” lexical distinction, and the “cuerpo de Cristo” disambiguation note in translation memory before any Phase 2 translation work begins — these three items carry the highest combined doctrinal-stakes-and-recurrence-frequency in the curriculum.
3. Sequence lesson delivery so that Christ’s self-giving headship (1:22-23) is taught before “cabeza” reappears in the marriage context (5:23), and so that mutual submission (5:21) and Christ’s self-sacrificial love (5:25) are never separated from 5:22-24 in any single lesson unit.
4. Attach mandatory historical-context notes to the slavery passage (6:5-9) distinguishing first-century household slavery from transatlantic chattel slavery, given the weight of that regional history.
5. Route all spiritual-warfare and cosmic-powers material (2:2; 3:10; 6:10-20) through native-speaker-informed theologian review specifically screened for Espiritismo/Santería/curanderismo syncretism risk before regional distribution.
6. Load the Ephesians translation_memory.json exclusively (not alongside a separate Romans file) for this curriculum’s Phase 2 work, since it already inherits every relevant Romans baseline entry verbatim, to avoid version drift between overlapping term databases.
