Executive Summary — Mark, English → Russian

Why it matters: Mark’s core passage (10:35–45) compresses six of the curriculum’s eight doctrines into a single, densely allusive sentence — Son of Man, servanthood, the necessity of the cross, and the ransom for many all converge in one verse. Russian has a thousand-year-old, doctrinally rich Christian vocabulary shared with Orthodoxy, so lexical gaps are rare — but that same shared vocabulary means several of Mark’s most load-bearing words (тайна, предание, крещение, раб) already carry a strong, specific competing meaning inside Russian Orthodox devotional and sacramental life. Get these wrong and the curriculum doesn’t sound foreign — it sounds like an unintended argument against Orthodoxy itself, or like it’s saying something Mark never said.

Key findings:

• Mark’s risk profile inherits Romans’ East-West/post-Soviet-secularization axis and adds a book-specific collision layer: narrative concealment language (the Messianic Secret) colliding head-on with Orthodoxy’s own technical vocabulary for the Sacraments (Святые Тайны) and Holy Tradition (Священное Предание).
• The doctrine registry documents 30 doctrine entries across the full book: 14 Critical, 8 High, 8 Medium, 0 Low — 22 of 30 doctrines require mandatory human theologian review, versus 8 for native speaker review only, and none cleared for automated review alone.
• The term registry documents roughly 70 individual theological terms: 17 Critical and 22 High (39 total, well over half) require priority human review — nearly double the proportion flagged in the Romans baseline, driven by Mark’s narrative-Gospel material and the density of the core passage.
• The single highest-stakes translation point in the entire curriculum is Mark 10:45’s ransom/substitution cluster (λύτρον/ἀντί/πολλῶν): искупление’s ordinary theological register in Russian already means “the Atonement generally,” which can silently absorb Mark’s specific, concrete “price paid to free a captive” claim into a vague generalization unless explicitly glossed with выкуп every time.
• Full-book coverage is confirmed: every chapter (1–16) has been reviewed; no chapter was silently omitted, and chapters contributing no new Critical/High vocabulary are explicitly marked “reviewed” against the doctrine matrix.

Risks:

• тайна Царства (4:11) — default collision with Святые Тайны (the Sacraments) could reframe the entire Messianic Secret doctrine as being about sacramental mystery-rites rather than Jesus’ deliberate identity-concealment. Critical.
• предание [людей/старцев] (7:3-13) — unqualified use reads as a direct polemic against Holy Tradition’s legitimacy, one of Orthodoxy’s core doctrinal categories. Critical.
• κατακυριεύω/“lord it over” (10:42) — shares its Russian root with Господь, Christ’s own Critical-risk Lordship title; if the wordplay isn’t surfaced explicitly, readers may hear an unintended critique of Christ’s own lordship rather than of worldly domination. Critical.
• раб/“slave” (10:44) — carries both a devotional asset (раб Божий, standard Orthodox self-designation) and a serious historical liability (serfdom, Gulag forced labor); mishandled, it reads as either pious cliché or an endorsement of coercion.
• хула на Духа Святого (3:28-29) — acute pastoral risk that anxious readers will believe they’ve committed the one unforgivable sin through ordinary doubt.
• Cry of dereliction (15:34) and Centurion’s Confession (15:39) — theologically sensitive claims about the nature of Christ’s forsakenness and identity that must follow Synodal precedent exactly and be exegetically explained, not silently resolved.

Opportunities:

• Russian’s shared Nicene heritage with Orthodoxy makes Christ’s divine Sonship, the Trinity, and the resurrection genuine common ground requiring precision, not defense against a rival framework — a real head start versus non-creedal-heritage languages.
• Several Mark-specific terms are cultural/liturgical assets, not risks: Преображение (Transfiguration) is a major shared feast; Осанна is already in Orthodox Palm Sunday liturgy; “Христос воскресе!” is arguably the single most recognized religious phrase in Russian culture; “испить чашу” is a live literary idiom that aids intelligibility for Jesus’ “cup” of suffering.
• раб Божий as a standing devotional self-designation gives Mark 10:44’s radical servant-slave paradox an intuitive, honored point of contact once the coercion-connotation is explicitly named and set aside.

Recommended actions:

1. Load assets/translation_memory.json (Mark) and assets/bible_term_registry.json (Mark) into every Phase 2 session alongside the Romans baseline files; the Mark file inherits 22 baseline terms exactly and adds ~48 new Critical/High/Medium/Low terms.
2. Enforce mandatory dual-term glossing (искупление + выкуп; за/вместо + взамен/в обмен на) at every occurrence touching Mark 10:45 and its echo at 14:24 — treat as non-negotiable, not stylistic.
3. Route all 22 theologian-tier doctrines and all 39 Critical/High terms through mandatory human theologian review per 12_ai_translation_requirements.md’s escalation rules before any segment is marked approved.
4. Enforce formula consistency mechanically (the sevenfold “tell no one,” the threefold надлежит, the fear/awe register split) across the whole book rather than trusting segment-by-segment translator judgment.
5. Brief all reviewers on the тайна/предание fencing requirement before work begins — this is the single highest-likelihood point of unintended sectarian offense in the entire curriculum.
