Executive Summary: Matthew — Greek Destination Language

Why it matters

Modern Greek is the direct, unbroken descendant of Matthew’s own Koine Greek — a translation-pair situation unique in this pipeline. For most of Matthew’s vocabulary there is no cross-linguistic gap at all: the modern word simply is the New Testament’s word. That advantage is also this curriculum’s central hazard. Two millennia of semantic drift in a single language — not translation into a foreign one — have pulled load-bearing terms in two directions: secular bleaching (μακάριος → “the deceased”; παρουσία → classroom “attendance”; μαθητής → “schoolchild”; κόλαση → traffic-jam hyperbole) and patristic/liturgical accretion (μυστήριο → “the Sacraments”; προσκυνώ → icon veneration; μετάνοια → the rite of Confession). Matthew intensifies this risk profile beyond Romans/Galatians and adds a new category: denominational-referent sensitivity, where the wording is stable but the doctrine’s referent (Matthew 16:18-19’s “rock” and “keys”) sits at the center of a live, centuries-old inter-tradition dispute.

Key findings

• All 28 chapters of Matthew reviewed; no chapter was found to contribute zero load-bearing vocabulary. Density peaks in chs. 5-7 (Sermon on the Mount, containing the core passage), 13 (Kingdom parables), 16-18 (church-founding texts), and 24-28 (Passion, Resurrection, Commission).
• 118 tracked terms in the Matthew-extended bible_term_registry.json: 33 Critical and 41 High risk (74 total, 63% of all tracked terms) require mandatory human theologian review on every occurrence.
• 35 doctrines mapped in doctrine_risk_registry.json: 21 Critical and 10 High (31 of 35, 89%) route to human theologian review; only 4 route to native speaker review and zero are automated-only — a materially higher review burden than the Romans/Galatians baseline.
• The core passage (Matthew 5:1-12, the Beatitudes) contains the single highest-risk lexical item in the entire curriculum: μακάριος/μακάριοι, whose dominant Modern Greek sense is “the late/deceased” (ο μακαρίτης) — a near-total sense-substitution risk at the exact text the whole curriculum is anchored to.
• A documented sectarian translation (the Greek New World Translation) circulates widely enough in Greece/Cyprus to require an explicit negative-check list: six specific departures (παρουσία as “presence”; two-class kingdom membership; annihilationist judgment; subordinationist Trinity framing at 28:19; tetragrammaton-insertion for Κύριος; “happy” for μακάριοι) must never be echoed.

Risks

• Beatitudes collapse (5:3-11): μακάριος’s dominant “deceased”/“blissfully oblivious” senses can invert the passage’s entire rhetorical force at the curriculum’s theological anchor.
• Kingdom flattening (throughout, ~32×): βασιλεία των ουρανών risks collapsing into a purely future, post-mortem “heaven” destination, erasing Matthew’s present-and-future tension.
• Sacramental collision (13:11): μυστήρια της βασιλείας risks being heard as “the Sacraments” or a whodunit “mystery,” fully displacing Jesus’ actual point.
• Parousia trivialization (24:3,27,37,39): the Second Coming’s technical term is dominated in everyday Greek by ordinary classroom “attendance-taking” — the single most severe secular-bleaching trap in the pipeline to date.
• Denominational adjudication risk (16:16-19): the transparent Πέτρος/πέτρα wordplay is a genuine asset, but careless framing could be read as taking a side in the historic Catholic/Orthodox papal-primacy dispute.
• Judgment trivialization/oversteering (25:46): κόλαση αιώνια is colloquially bleached toward hyperbole on one side and risks annihilationist reinterpretation (a documented sectarian departure) on the other.
• Discipleship flattening (throughout; climactic at 28:19): μαθητής/μαθητεύσατε’s ordinary “schoolchild”/“enroll” sense risks reducing total-life apprenticeship to classroom enrollment at the Great Commission’s climactic verb.

Opportunities

• Zero-gap LXX access: a Greek reader can read Matthew’s Old Testament citations (Isaiah 7:14 at 1:23; Psalm 118:22 at 21:42; Psalm 118:25-26 at 21:9) in the same language Matthew quotes them in — a genuine interpretive asset unavailable to any other Language Package in this pipeline.
• Liturgical verbatim assets: the Beatitudes (Third Antiphon), the Lord’s Prayer, the Words of Institution (26:26-28), and the Trinitarian baptismal formula (28:19) are already memorized/chanted verbatim by most Orthodox Greek readers — reuse this wording exactly rather than modernizing it.
• Native ἀγάπη/ἔρωτας/φιλία distinction: Greek’s own vocabulary for love supports the greatest-commandment teaching (22:37-39) with a precision most target languages lack.
• Transparent Πέτρος/πέτρα wordplay: an asset unavailable to most languages, usable to teach Matthew 16:18 vividly once the denominational-referent caution is honored.
• Ανάσταση as living feast: Greek Orthodox Easter already centers resurrection; the curriculum’s task is doctrinal precision, not persuasion.

Recommended actions

1. Load the Matthew-extended translation_memory.json, bible_term_registry.json, and doctrine_risk_registry.json — together with the unchanged Romans/Galatians baseline — before any Phase 2 segment processing.
2. Route all 74 Critical/High terms and all 31 Critical/High doctrines to mandatory human theologian review per the escalation rules in 12_ai_translation_requirements.md; native speaker review remains sufficient only for the 4 Medium-tier doctrines (greatest commandment, woes against hypocrisy, Gentile inclusion/mission, Sabbath authority).
3. Apply the mandatory explanatory-note requirement at every occurrence of μακάριος, βασιλεία των ουρανών, μυστήρια της βασιλείας, παρουσία, and κόλαση αιώνια — these five terms alone account for the highest-severity risk cluster in the curriculum.
4. Run every Matthew segment touching 24:3-44, 25:46, and 28:19 against the six-point New World Translation negative-check list before approval.
5. Hold Matthew 16:16-19 to a strict interpretation-neutral standard: present Christ’s authority to found his church on apostolic confession without adjudicating the Catholic/Orthodox papal-primacy dispute.
6. Reuse established Greek liturgical wording verbatim (no stylistic modernization) at the Beatitudes, the Lord’s Prayer, the Words of Institution, and the baptismal formula, per 05_translation_landscape.md.
