Comparative Theology

Trinity

• Protestant: One God, three co-equal, co-eternal Persons (Father, Son, Holy Spirit); a mystery affirmed, not fully explained
• Catholic: Same core doctrine as Protestant, formally defined at Nicaea/Constantinople/Chalcedon; heavy liturgical and creedal reinforcement
• Orthodox: Same Nicene doctrine, with particular emphasis on the Father as the monarchical source (arche) of the Trinity
• Jewish: Rejected; strict monotheism (Shema), no plurality within the divine unity
• Islamic (Twelver Shia): Rejected as the paradigm case of shirk (associating partners with God), violating tawhid; shared fully with Sunni Islam. Shia theology adds no separate Trinity doctrine of its own but layers the Imamate (see Sonship row) as a distinct axis of religious authority alongside this shared objection
• Other Religious Perspectives: Zoroastrianism: no Trinity concept; a single supreme deity, Ahura Mazda, opposed by a hostile spirit, Angra Mainyu/Ahriman, in a cosmic ethical dualism, not a triune unity
• Secular: No transcendent referent; Trinity read as a historical doctrinal construction, often engaged (if at all) as a philosophical curiosity or as evidence of institutional religion’s internal disputes

Deity/sonship of Christ

• Protestant: Christ is fully God and fully man; “Son of God” denotes eternal, ontological sonship, not physical procreation
• Catholic: Same as Protestant; reinforced by conciliar Christological definitions
• Orthodox: Same as Protestant/Catholic; strong emphasis on the Incarnation as the means of theosis (human participation in divine life)
• Jewish: Jesus is, at most, a teacher or failed messianic claimant; deity or sonship claims are theologically impossible within Jewish monotheism
• Islamic (Twelver Shia): Firmly rejected as shirk; “Son of God” is heard as claiming God took a physical consort or offspring, a reading the Quran (112:3, 19:35) explicitly denies. Twelver Shia theology adds a second, distinct axis: ultimate religious authority and “who mediates God’s will” runs through the Imamate, the line of twelve infallible divinely-appointed successors to Muhammad beginning with Ali, not through any sonship claim; Jesus (Isa) is honored as a prophet but institutionally subordinate to this framework
• Other Religious Perspectives: Zoroastrianism has no incarnate-deity concept; Ahura Mazda acts through intermediary emanations (the Amesha Spentas), a structurally different, non-personal mediation pattern that can make “incarnation” register as one more emanation rather than a singular, unique event
• Secular: Historical-Jesus scholarship at most; “son of God” read as an ancient honorific title (used for kings, emperors) rather than a metaphysical claim

Salvation / grace

• Protestant: By grace alone, through faith alone, in Christ alone (sola gratia, sola fide); a forensic, unmerited gift
• Catholic: Grace-enabled, faith working through love, cooperant with sacramental participation and good works
• Orthodox: Synergistic: divine grace and human free cooperation together effect theosis, ongoing transformation into the likeness of God
• Jewish: Right relationship with God through covenant faithfulness, repentance (teshuvah), and observance of the commandments (mitzvot); no single “moment” of salvation
• Islamic (Twelver Shia): Salvation through submission to God’s will, right belief, and the deeds-weighing framework (mizan) at final judgment. Twelver Shia popular piety adds the Karbala martyrdom-intercession pattern: honoring Imam Hussein’s suffering at Karbala (Muharram mourning rituals, ta’ziyeh passion plays) is widely believed to secure intercessory benefit, a structurally close analogue to substitutionary atonement that a translation must actively distinguish, not merely a deeds framework to contrast with
• Other Religious Perspectives: Zoroastrianism: the soul’s deeds are weighed at the Chinvat Bridge, wide underfoot for the righteous and blade-narrow for the wicked, an independent, pre-Islamic deeds-based framework that reinforces rather than merely echoes the Islamic mizan
• Secular: No metaphysical salvation; “salvation” language, if used at all, is repurposed for psychological wellbeing, social liberation, or self-actualization

Sin

• Protestant: Inherited guilt and corruption from Adam (federal headship), affecting all humanity; requires atonement, not merely correction
• Catholic: Same doctrine of original sin, formally defined; mitigated in Catholic theology by sacramental grace from baptism onward
• Orthodox: Emphasizes ancestral consequence and corruption (mortality, tendency to sin) more than inherited legal guilt; stronger emphasis on human free will to cooperate with grace
• Jewish: No doctrine of inherited guilt; each person is responsible for their own sins, atoned through repentance, prayer, and (historically) sacrifice
• Islamic (Twelver Shia): No inherited guilt; humans are born in a state of innate purity (fitrah) and sin is a matter of individual wrong acts weighed at judgment, not a corrupted nature. Zoroastrian dualism (see Other Religious Perspectives) independently reinforces this Persian-cultural default toward a deeds-weighing, not inherited-guilt, framework
• Other Religious Perspectives: Zoroastrianism: humans are morally free agents whose good thoughts, words, and deeds actively combat the cosmic forces of Angra Mainyu; sin is a chosen alignment with the destructive spirit, not an inherited condition
• Secular: Sin reframed as harmful behavior, social wrongdoing, or psychological dysfunction, with no reference to a transcendent moral order or inherited condition

Atonement

• Protestant: Christ’s substitutionary, penal death fully satisfies God’s justice on behalf of sinners, a completed, once-for-all historical act
• Catholic: Same core substitutionary logic, understood within a broader sacramental economy (the Mass as ongoing participation in Christ’s one sacrifice, not a repetition of it)
• Orthodox: Christus Victor emphasis alongside substitution: Christ’s death and resurrection defeat death and corruption, opening the path to theosis
• Jewish: No singular atoning sacrifice; historically the Temple sacrificial system, now replaced by repentance, prayer, and charity (teshuvah, tefillah, tzedakah)
• Islamic (Twelver Shia): No concept of vicarious atonement for sin in mainstream doctrine; the Quran’s crucifixion-denial (4:157) removes the event itself from consideration. The Karbala pattern (see Salvation row) is the closest popular-devotional analogue and the primary translation risk: it is innocent-suffering-that-benefits-others in form, but categorically different in that it is ritually re-enacted and re-honored annually rather than a single, sufficient, historical event
• Other Religious Perspectives: Zoroastrianism has no atonement doctrine; moral standing is a running ledger of one’s own good and bad thoughts, words, and deeds, weighed individually at the Chinvat Bridge, not transferred from or credited by another
• Secular: No atonement concept; if engaged at all, read as a psychologically or anthropologically interesting example of scapegoat or sacrifice ritual (per thinkers like René Girard), not a live theological claim

Resurrection

• Protestant: Christ’s bodily resurrection is historical, foundational, and the guarantee of believers’ own future bodily resurrection
• Catholic: Same core doctrine, with strong liturgical centrality (Easter as the highest feast)
• Orthodox: Same core doctrine, central to the theology of theosis and the defeat of death
• Jewish: General bodily resurrection at the end of days is a traditional Jewish eschatological belief (especially in Rabbinic/Pharisaic Judaism), but Jesus’s own resurrection specifically is denied
• Islamic (Twelver Shia): The Quran’s crucifixion-denial (4:157, widely read as “it was made to appear so to them”) removes the event Christians claim occurred; a resurrection cannot follow a death Islamic tradition holds did not happen in the way described. Shia eschatology further subordinates Jesus’s own return: popular expectation centers on the Hidden Twelfth Imam (Mahdi)‘s reappearance, with Jesus returning shortly after in a supporting role (variously depicted praying behind the Mahdi or fighting alongside him against the Dajjal), not as the central eschatological figure
• Other Religious Perspectives: Zoroastrianism has its own eschatology (frashokereti, a final cosmic renovation and general resurrection at the end of time) that is structurally distinct but can create a background expectation that “resurrection” language refers to a distant cosmic-final event rather than one specific historical man’s bodily return to life
• Secular: No literal resurrection; treated as legend, metaphor for renewal, or, at most, a claim about the disciples’ psychological experience of Jesus’s continued significance

Authority of Scripture

• Protestant: The Bible (66 books) alone is the final, sufficient, inspired written authority (sola scriptura)
• Catholic: Scripture plus church tradition and magisterial teaching authority together
• Orthodox: Scripture read and interpreted within and inseparable from the church’s living tradition and the Councils
• Jewish: The Tanakh (Hebrew Bible) alone; the New Testament carries no authority
• Islamic (Twelver Shia): The Quran is God’s final, literal, untranslatable word (wahy, verbatim dictation), abrogating and superseding earlier scriptures (naskh); the Torah (Tawrat), Psalms (Zabur), and Gospel (Injil) are honored in principle as earlier revelations but are widely held, per the doctrine of tahrif, to have been textually corrupted from their original form, which is the standard, shared Sunni-and-Shia basis for treating today’s Bible as unreliable evidence against Islamic teaching
• Other Religious Perspectives: No parallel scripture-authority claim from Zoroastrianism relevant to Bible translation specifically, though the Avesta functions analogously as authoritative scripture within that tradition
• Secular: No transcendent authority; the Bible read as an ancient literary and historical document, subject to the same critical-historical methods as any other text

Agreement and divergence

Agreement across Protestant, Catholic, and Orthodox traditions on the doctrines above is substantial; divergence within Christianity here is mostly a matter of emphasis (forensic versus participatory salvation language, sola scriptura versus scripture-plus-tradition) rather than contradiction, and this Language Package follows the Protestant/evangelical rendering consistent with the Tarjome Ghadeem/Mojdeh translation lineage without needing to adjudicate the Catholic/Orthodox differences for its Persian-speaking audience, who are overwhelmingly evangelical or evangelical-adjacent house-church believers. The real divergence this Language Package has to manage carefully is with Twelver Shia Islam, and it runs on two axes at once rather than one: the tawhid/shirk objection shared with Sunni Islam everywhere else in this pipeline (Trinity, incarnation, sonship, deity of Christ are all shirk), and a second, Shia-specific axis concerning who legitimately mediates God’s will and intercedes for believers, running through the Imamate and expressed devotionally through the Karbala martyrdom-intercession pattern and popular shafa’at (intercession) practice centered on the Imams. A translator or reviewer trained only on generic or Sunni-context Islamic theology will catch the first axis and miss the second entirely, which is why doctrine_risk_registry.json routes salvation, intercession, messianic promise, and resurrection all to Critical/human-theologian review specifically because of this second axis, not the first alone.

Misunderstandings to avoid

Do not present Christ’s atoning death as though its distinctiveness lies simply in “one man suffering for others,” since that framing is already fully occupied, and arguably strengthened, by the Karbala pattern; the distinctiveness has to be located in the completed, sufficient, historical, non-repeated nature of the event and in Christ’s unique identity as the eternal Son, not merely in the shape of vicarious suffering. Do not translate “Son of God” euphemistically (see the Hezare No controversy in Translation Landscape) to avoid the shirk objection; softening the term does not remove the underlying theological claim, it only obscures it, and it has a documented history of provoking backlash within the Iranian church itself when tried. Do not treat Shia Islam as a doctrinal footnote to Sunni Islam; the Imamate and its associated intercession/eschatology content is a first-order theological system in its own right for this audience, not a minor variant.

Sensitive terminology

فیض (feyz, grace) requires the most careful handling of any single term in this Language Package. In Illuminationist philosophy (Suhrawardi) and in Mulla Sadra’s Transcendent Theosophy, both influential strands of Persian intellectual and popular religious culture, feyz denotes divine emanation, being automatically overflowing from God into creation as an impersonal metaphysical process, not a freely willed, particular, unmerited gift given to a specific person. Used without correction, feyz risks teaching Romans’ doctrine of grace as an ambient cosmic outflow rather than God’s personal, gracious initiative toward sinners in Christ; every occurrence must be anchored to the specific, personal, historical gift secured through Christ. شفاعت (shafa’at, intercession) requires similar care given how developed and popularly central Shia intercession practice already is (see Comparative Theology table, Salvation row, and the Karbala discussion); Christ’s intercession (Romans 8:26-27, 34) must be taught as exclusive and sufficient, engaging this popularly central category directly rather than avoiding it.

Historical controversies specific to Persian Bible translation

The most significant documented controversy in modern Persian Bible translation is the reception of the Hezâre-ye Now (New Millennium Version), an Elam Ministries translation published in 2014 with the stated aim of being more approachable to Muslim-background readers. Existing Language Package research (carried forward from this document’s prior draft) holds that the translation softened theologically loaded phrases, most notably around “Son of God,” and that this provoked significant backlash within Iranian Protestant and house-church circles, many of which continued to prefer the older, unsoftened Tarjome Ghadeem and Mojdeh translations specifically to avoid this dilution. Spot-checking the New Millennium Version’s text directly (via its YouVersion edition) shows the well-known verse John 3:16 rendered with the standard literal “پسر یگانهٔ خود” (his only/unique Son), so the softened rendering, if it occurred, was evidently not applied uniformly across the text; this Language Package was not able to independently re-locate the specific softened passage(s) originally cited, and that specific claim should be treated as reported and plausible, consistent with the broader, well-documented global controversy over Muslim-idiom Bible translation choices around “Son” and “Father” language (a controversy that led the World Evangelical Alliance and major translation agencies including SIL and Wycliffe to commission formal reviews and issue clarified translation standards in the early 2010s), rather than as independently re-verified fact specific to this one Persian edition. Either way, this Language Package’s own position in that live debate is unambiguous and unchanged from the prior draft: it follows the unsoftened, literal پسر خدا precedent established by Tarjome Ghadeem and Mojdeh, not any softened alternative.
