Executive Summary: Ephesians (English → Greek)

Why it matters

Ephesians is being added to a Language Package where Modern Greek reader and New Testament author share the same language — a zero-translation-gap advantage no other destination language in this pipeline has. That advantage is also the risk: Ephesians’ densest, most doctrinally load-bearing vocabulary (μυστήριον, σῶμα, πλήρωμα, ἐνέργεια, οἰκονομία, προορίζω, κοσμοκράτορες) sits directly on the fault line between two millennia of Greek Orthodox theological accretion and everyday secular bleaching. Get the glossing wrong and a Greek reader either hears the letter’s own argument overwritten by patristic sacramental categories, or hears its most important words (predestined, mystery, filled with power, submit) reduced to tourism, puzzle-novels, electricity bills, and occupation-era subjugation. The core passage, Ephesians 2:1–10, sits at the convergence of the package’s two most severe pre-existing Critical risks (χάρη, σωτηρία) plus three new ones (ποίημα, unqualified ἔργα, νεκρός), making it the theological anchor this whole curriculum must get right first.

Key findings

• 10 Critical-risk and 9 High-risk doctrines (19 of 28 total Ephesians doctrines) require mandatory human theologian review at every occurrence — the highest theologian-review density of any curriculum built on this Language Package so far.
• Ephesians introduces 6 new Critical-risk terms and 15 new High-risk terms to the glossary (per 08_core_glossary.md), on top of the baseline’s own Critical terms (χάρη, σωτηρία, κλήση, εκλογή, Κύριος, Θεός, Άγιο Πνεύμα, Πατέρας, άγιοι, ανάσταση) which recur throughout.
• Three terms — μυστήριον, ἐνέργεια/ἐνεργέω, and κοσμοκράτορες — sit on both the secular-bleaching axis and the patristic-accretion axis simultaneously, a dual-direction risk category essentially unique to Ephesians within this pipeline.
• προορισμός (“predestined”) is the single most severe individual risk identified: its dominant Modern Greek sense is “travel destination,” and unlike almost every other flagged term, no alternative Greek word exists to relieve the pressure.
• The letter’s household-code material (5:21–6:9) concentrates the highest number of culturally sensitive, not merely lexically ambiguous terms in the book (υποτάσσομαι, δούλοι, κύριοι), requiring joint theologian-plus-native-speaker review rather than either alone.
• Genuine missing vocabulary (no ready Greek word at all) is rare — only 4 items in the whole book (ἀνακεφαλαιώσασθαι, θυρεός, the ῥήμα/λόγος distinction, corporate τέλειος ἀνήρ) — confirming this Language Package’s structural zero-gap advantage holds even under Ephesians’ unusual doctrinal density.

Risks

• σῶμα Χριστού (body of Christ) collides directly with the standing liturgical name for the consecrated Eucharistic host; mishandling in either direction (suppression or conflation) misrepresents both Paul’s ecclesiology and Orthodox sacramental theology.
• μυστήριο μέγα (5:32) compounds the μυστήριον risk with the fact that marriage is itself an Orthodox Sacrament — the single most pastorally delicate verse-level convergence in the curriculum.
• Intra-book vocabulary collision: the corporate “one new man” (2:15, καινός ἄνθρωπος) and the individual “new self” (4:22-24, νέος ἄνθρωπος) are lexically adjacent but doctrinally distinct; conflating them collapses two separate teachings (Jew-Gentile unity vs. personal moral renewal) into one.
• False-friend risk from the existing baseline: translators pattern-matching Ephesians 2:9’s unqualified “ἔργα” onto the Galatians-established “ἔργα νόμου” (Torah-observance) will wrongly narrow Paul’s universal exclusion of all human merit.
• Existing circulating teaching material in the wider Greek Evangelical/Protestant landscape sometimes recasts Ephesians 6:12’s cosmic powers as merely socio-political “power structures” — an ideologically comfortable misreading this curriculum must not echo.

Opportunities

• οἰκονομία is a rare case where Orthodox patristic accretion (“η θεία οικονομία,” the divine economy) actually supports rather than distorts Paul’s own sense (3:2, 3:9) — a teaching asset to exploit explicitly, not merely a risk to fence.
• Ephesians 5:21–33’s marriage material lands directly on the Orthodox wedding rite’s own crowning ceremony (στεφάνωμα), which quotes this passage liturgically — a strong, ready-made cultural bridge for teaching Christ’s self-giving love as the pattern for marriage.
• The sevenfold unity confession (4:4–6) and several LXX-quotable phrases (Genesis 2:24 at 5:31; Exodus 20:12 at 6:1–2) are zero-gap assets a Greek reader can access in the very words Paul himself used.
• Greek grammar itself supplies pedagogical tools unavailable to any other Language Package: the single article governing “ποιμένας καὶ διδασκάλους” at 4:11, and the neuter/feminine gender mismatch in 2:8’s “τοῦτο,” can be taught directly from the primary text rather than argued secondarily.

Recommended actions

1. Load translation_memory.json v3, bible_term_registry.json, and doctrine_risk_registry.json before any Phase 2 segment translation; enforce the Ephesians Additions section of 12_ai_translation_requirements.md alongside the Romans/Galatians baseline.
2. Route all 19 theologian-tier doctrines and every occurrence of the three dual-axis Critical terms (μυστήριον, ἐνέργεια, κοσμοκράτορες) through mandatory human theologian review with a standing footnote apparatus, not a one-time gloss.
3. Require joint theologian-plus-native-speaker review specifically for Ephesians 5:21–6:9 (υποτάσσομαι, δούλοι, κύριοι), given the compounding of lexical risk with contemporary social sensitivity.
4. Track the καινός ἄνθρωπος (2:15) vs. παλαιός/νέος ἄνθρωπος (4:22-24) distinction explicitly in the segment cache to prevent cross-contamination between the corporate-unity and individual-renewal doctrines.
5. Use Today’s Greek Version (TGV, YouVersion version_id 281, book code EPH) as the reference translation and hyperlink target throughout Phase 2 output.
