Glossary
Definitions of the theological and scholarly terms used across this site. Click any term to jump to its entry, or browse alphabetically.
A
Accusative
A grammatical case that most characteristically marks the direct object — the thing directly acted upon by a verb — and answers "what?" or "whom?" In Greek it also limits or defines the extent of an action (accusative of respect, of measure, of time's duration) and frequently follows certain prepositions. Hebrew can mark a definite direct object with the particle ʼēt (אֵת), though this is a function word rather than a case ending of the sort Greek possesses.
Adoptionism
The view that Jesus was a normal human being who was "adopted" as God's Son at a particular moment — most commonly his baptism (cf. Mark 1:9–11) or resurrection (cf. Acts 13:33; Romans 1:4). A recurring Christological category in early Christianity, distinct from Dynamic Monarchianism, though the two are sometimes conflated in secondary literature.
Alexandrian text-type
The Alexandrian text-type is a form of the Greek New Testament associated with Egypt and especially the scholarly traditions of Alexandria, preserved in several of the earliest and most carefully copied witnesses. It is generally terser and is often judged by editors to preserve earlier readings than the fuller Byzantine text-type, partly because it shows less harmonization. Most modern critical editions of the New Testament lean heavily on Alexandrian witnesses.
Anarthrous
Describing a Greek noun that appears without the definite article — the opposite of articular. Because Greek has no indefinite article, the absence of the article can signal that a noun is qualitative or indefinite rather than a specific, identified thing, though this is a tendency rather than a rule. The point is often raised over how to render kai theos ēn ho logos ("and the Word was God") in John 1:1.
Angel (מַלְאָך / ἄγγελος)
From Hebrew malʼakh (מַלְאָך) and Greek angelos (ἄγγελος), both meaning simply "messenger." The word does not inherently denote a supernatural being — it is used in the OT for both human messengers (2 Sam 11:19; Hag 1:13) and divine agents. The "angel of the LORD" in the OT speaks and acts with God's full authority, sometimes even speaking as God in the first person (Gen 22:11–12; Exod 3:2–6), because in Jewish agency the messenger represents the sender. This is significant for the Christophany debate: Trinitarians and Logos theologians often identify these appearances as the pre-incarnate Christ, while Biblical Unitarians read them as God acting through his agents — exactly what the word "angel" means. See also Shaliach and Christophany.
Antecedent
The word or phrase to which a later pronoun (or other pro-form) refers back — its grammatical referent — so that in "Paul wrote because he was concerned," "Paul" is the antecedent of "he." In Greek, gender and number agreement between a pronoun and its antecedent often resolves ambiguity that English word order alone cannot, making the identification of antecedents an important interpretive task. Where an antecedent is unclear or contested, the meaning of a whole passage can hinge on the decision.
Anthropomorphism
The portrayal of God in human terms — with hands, eyes, a face, or bodily actions such as walking, hearing, and resting (Greek, "human form"). When Genesis describes God walking in the garden "in the cool of the day" (Gen 3:8), the language is anthropomorphic, accommodating the infinite to human understanding rather than asserting that God has a body. A related figure, anthropopathism, ascribes human emotions (anger, regret, jealousy) to God, and the device shares its imaginative logic with personification.
Aorist
A Greek tense whose core contribution is perfective aspect — it presents an action as a whole, viewed from the outside, without commenting on its internal duration or progress. The name derives from aoristos ("undefined, unbounded"), and in the indicative mood it typically refers to past time, though outside the indicative the time reference largely disappears and aspect dominates. It is frequently contrasted with the imperfect and present tenses, which carry imperfective aspect.
Apollinarianism
The view (condemned at Constantinople 381) that Christ had a human body and soul but that his mind/spirit was replaced by the divine Logos.
Apostrophe (rhetorical)
As a rhetorical device — not the punctuation mark of the same name — a sudden, impassioned turn to address someone absent or dead, or to address a thing, place, or abstraction as if it could hear (Greek, "a turning away"). Prophets and poets break off to cry out directly to mountains, to the sea, or to Death itself, as in "O death, where is your victory? O death, where is your sting?" (1 Cor 15:55). Closely allied to personification, since the thing addressed is treated as a responsive person.
Arianism
The position attributed to Arius of Alexandria (c. 256–336) that the Son was created by the Father, and thus "there was a time when he was not." Often conflated with all forms of subordinationism, though many who opposed Nicaea (like the homoiousians) were not Arians in this strict sense.
Articular
Describing a Greek noun that appears with the definite article (ho, hē, to, "the") — the opposite of anarthrous. The presence of the article often marks a noun as definite, identified, or previously mentioned, and Greek deploys the article far more flexibly than English — before abstract nouns, proper names, and whole clauses. Discerning why a noun is articular or anarthrous is a staple of careful exegesis, though the article's force must always be weighed in context rather than assumed.
Aseity
The property of self-existence — existing through oneself rather than being caused by another. A foundational attribute of God in the Judeo-Christian tradition: God is uncaused, self-sufficient, and depends on nothing outside himself for his existence. All three Christological positions on this site affirm God's aseity. The debate is whether the Son shares it: Trinitarians say yes (the Son is co-eternal and self-existent); Logos theologians say the Father alone has aseity while the Son's existence derives from the Father; Biblical Unitarians agree with the Logos position on this point — only the Father is the self-existent God.
assimilation
In textual criticism, assimilation is the scribal tendency to make one part of a text conform to another — adjusting wording, grammar, or phrasing to match a nearby word, a familiar formula, or a parallel passage. Harmonization of parallel passages is a common subtype. Like most scribal smoothing, assimilation generally produces a later reading, so the less conformed wording is usually preferred.
attestation
Attestation refers to the body of witnesses that support a given reading — how widely, how early, and how independently it is documented. A reading is said to be well "attested" when it appears across many early and geographically diverse witnesses. Scholars weigh both the quantity and especially the quality of attestation, since broad but late support may count for less than narrow but early support.
autograph
In textual criticism, the autograph is the original manuscript of a writing as first produced by its author (or the author's scribe) — not, in this sense, a celebrity signature. No biblical autograph survives; every text is known only through later copies, which is why textual criticism exists at all. Because the autograph is irrecoverable directly, editors aim instead to reconstruct the earliest attainable form of the text from the surviving witnesses.
B
Byzantine text-type
The Byzantine text-type is the form of the Greek New Testament that came to dominate the manuscript tradition of the Greek-speaking Byzantine Empire and survives in the largest number of copies — hence its other name, the "Majority Text." It tends to be smoother and fuller than the rival Alexandrian text-type, sometimes through conflation and harmonization. Most scholars regard its distinctive readings as generally later, though its sheer breadth of witnesses still carries weight.
C
Calque
A "loan translation": a word or phrase formed by translating each element of a foreign expression piece-by-piece into another language, rather than borrowing it as a sound (which would be transliteration). When the translators of the Septuagint and the New Testament writers rendered Hebrew idioms component-by-component into Greek, they produced calques that read as distinctly Semitic — a frequent source of the constructions scholars label Semitisms. The English "scapegoat" is itself a calque coined to render a difficult Hebrew term.
Cappadocian Fathers
Basil of Caesarea, Gregory of Nazianzus, and Gregory of Nyssa — three 4th-century theologians who were instrumental in formulating the doctrine that God is one essence (ousia) in three persons (hypostaseis), which became the basis for the Council of Constantinople (381).
Chalcedon
The Council of Chalcedon (AD 451), which defined the "two natures" doctrine: Christ is fully God and fully human, with the two natures united "without confusion, without change, without division, without separation."
Chiasm
A symmetrical arrangement of elements in inverted, mirror-image order — A–B–B′–A′ — named after the X-shaped Greek letter chi (χ). The pattern can govern a single sentence or an entire chapter, and its turning point often carries the passage’s emphasis; a compact verbal example is "the Sabbath was made for man, not man for the Sabbath" (Mark 2:27). Chiasm shares its framing logic with inclusio, since the outermost A–A′ elements bracket the unit.
Christophany
An appearance of Christ (or the pre-incarnate Logos) in the Old Testament. Trinitarians and Logos theologians often identify OT theophanies as christophanies. Biblical Unitarians reject this as anachronistic reading, preferring to understand these appearances through the existing lens of Jewish agency and the meaning of the word "angel" — Hebrew malʼakh (מַלְאָך), Greek angelos (ἄγγελος) — which simply means "messenger," not a supernatural being. An "angel of the LORD" is a messenger sent by God, acting and speaking with God's authority without being God. See also Shaliach.
codex
A codex is a book made of leaves bound along one edge — the format that replaced the scroll and is the ancestor of the modern book. Early Christians adopted the codex remarkably early for their scriptures, and the great fourth- and fifth-century parchment Bibles (such as Codex Sinaiticus and Codex Vaticanus) are among the most important witnesses to the New Testament text. A codex could hold far more text than a single scroll and allowed readers to flip directly to a passage.
Cognate
A word in one language that shares a common ancestral origin with a word in a related ("sister") language, and so often carries a similar form and meaning. Because Hebrew belongs to the Semitic family alongside Akkadian, Ugaritic, Arabic, Aramaic, and others, scholars frequently illuminate a rare or obscure Hebrew word by comparing its cognates in those languages — a technique especially valuable for terms whose etymology or meaning is otherwise uncertain. Cognate evidence must be used cautiously, since related words can drift apart in sense over time.
Cohortative
A Hebrew first-person volitional verb form expressing the speaker's will, wish, or resolve — "let me," "let us," or "may I" — typically marked by an added -â ending on the prefix conjugation. It conveys self-encouragement, intention, or a request for permission, as in "let us make humankind in our image." It belongs to the same volitional family as the second- and third-person jussive and the imperative.
colophon
A colophon is a note placed at the end of a manuscript (or of one of its books) in which the scribe records information such as the title completed, the date, the place of copying, the scribe's name, or a pious closing remark. Colophons can be invaluable for dating and localizing a manuscript and for tracing how a text was transmitted. They are the handwritten ancestor of the publication details now found at the front of a printed book.
Comma Johanneum
A disputed passage in 1 John 5:7–8 that explicitly mentions "the Father, the Word, and the Holy Ghost: and these three are one." Absent from all Greek manuscripts before the 16th century, it is now recognized by virtually all scholars as a later interpolation.
conflation
Conflation occurs when a scribe, faced with two different readings in different copies, combines them into a single fuller reading rather than choosing between them. The result preserves both wordings side by side, which usually betrays the conflated reading as secondary, since the simpler alternatives are more likely original. Conflation is one of the tendencies that gives the Byzantine text-type its characteristic fullness.
Construct State
A Hebrew grammatical state in which a noun is bound closely to a following noun to express a relationship of possession, source, or description — the so-called "construct chain" (e.g., dĕbar YHWH, "the word of the LORD"). The first noun (in the construct state) is often shortened in form and loses its own article, while definiteness is governed by the final, "absolute" noun of the chain. This construction does much of the work that the Greek genitive performs, and a single chain can express possessive, attributive, or partitive ideas depending on context.
Copula
A linking verb — chiefly forms of "to be" — that joins the subject of a clause to a predicate noun or adjective, asserting identity or description rather than an action. In Greek the copula is eimi ("I am"), and in such equative sentences the predicate nominative is frequently anarthrous while the subject is articular. Biblical Hebrew often omits the copula entirely in the present tense, forming "verbless" or nominal clauses in which the linking "is" must be supplied in translation (e.g., "the LORD is my shepherd").
D
Dative
A Greek grammatical case that most often marks the indirect object — the person to or for whom something is done — and answers "to whom?" or "for whom?" Beyond this, the Greek dative absorbs functions that other languages assign to separate cases, expressing instrument or means ("by"), location ("in, at"), and association ("with"), so its precise nuance depends heavily on context and prepositions. Biblical Hebrew has no dative case and conveys these relations through prepositions such as lĕ- ("to, for").
Dead Sea Scrolls
The Dead Sea Scrolls are a collection of Jewish manuscripts discovered from the late 1940s onward in caves near the Dead Sea, principally at Qumran, and generally dated to roughly the last two centuries BC and the first century AD. They include the oldest known copies of Hebrew biblical books — many centuries older than the medieval Masoretic Text — and so are invaluable witnesses to the Old Testament. They reveal both the remarkable stability of the Hebrew text and the existence of variant forms, some agreeing with the Septuagint.
Definite article
A word that marks a noun as specific or already identified — in English "the." Both ancient Greek (ho, hē, to) and Biblical Hebrew (the prefixed ha-) possess a definite article but no indefinite article, so the article's presence or absence carries far more interpretive weight than in English. A noun with the article is articular; one without it is anarthrous. Greek also deploys the article more freely than English — before proper names, abstract nouns, and even whole clauses — so its force must always be judged in context, as in the much-discussed contrast between ho theos and the article-less theos in John 1:1.
Deponent
A traditional label for a Greek verb that appears in middle or passive form but is translated with an active meaning — the verb is said to have "laid aside" (Latin deponere) its active forms, as with erchomai ("I come") or ginomai ("I become"). Many recent grammarians question the category, arguing that these verbs are genuinely middle in meaning — denoting actions in which the subject is specially involved — and that "deponent" obscures a real semantic force; the term is therefore increasingly used with caution.
Docetism
The view that Christ only appeared to have a human body and to suffer, but was actually purely divine. Rejected by all four positions presented on this site.
Doxology
A liturgical formula of praise to God. NT doxologies directed to or through Jesus are significant evidence in debates about early Christian worship practice.
Dynamic equivalence
A translation philosophy, associated especially with the linguist Eugene Nida, that aims to reproduce the meaning and effect of the original in natural, idiomatic language for the new reader — often summarized as "thought-for-thought"; the term "functional equivalence" is now frequently preferred. Translations toward this end of the spectrum (such as the NLT or CEB) read fluently and clarify difficult idioms, but involve more interpretive decisions and can obscure the original wording. It is conventionally contrasted with formal equivalence, the two marking ends of a continuum rather than a strict either/or.
Dynamic Monarchianism
An early Christological position holding that God is one person (the Father) and that Jesus was a human being uniquely empowered by God's Spirit. "Dynamic" refers to the divine power (dynamis) operating through Jesus. Paul of Samosata is the most prominent historical representative. Modern Biblical Unitarianism is broadly in this tradition.
E
Ebionism
An early Jewish-Christian movement that regarded Jesus as the Messiah but rejected his divinity and virgin birth. The name derives from Hebrew evyon (אֶבְיוֹן), meaning "poor" — likely a self-designation reflecting the community's voluntary poverty (cf. "blessed are the poor"). Despite later church fathers attributing the movement to a founder named "Ebion," no such person is attested in any early source; the name almost certainly refers to the group's character, not an individual. They kept Jewish law and used only the Gospel of Matthew. Closely related to Adoptionism. Sometimes cited as evidence that the earliest Jewish Christians did not consider Jesus divine.
Eisegesis
Reading meaning into a text (importing assumptions), as opposed to exegesis (drawing meaning out of the text).
Ellipsis (rhetorical)
In rhetoric and grammar — distinct from the punctuation mark of the same name — the deliberate omission of one or more words that the reader is expected to supply from context (Greek, "a falling short"). Hebrew poetry uses it constantly, as when the second line of a couplet drops a verb already stated in the first ("To you, O LORD, I lift up my soul; O my God, in you I trust…," Ps 25:1–2). It is the inverse of pleonasm, achieving compression and force through what is left unsaid.
Eternal generation
The Trinitarian doctrine that the Son is eternally "begotten" by the Father — not created at a point in time, but perpetually generated within the Godhead. Distinguishes the Son from created beings while maintaining his derived relationship to the Father.
Etymology
The study of a word's historical origin and development — where it came from, its earlier forms, and its relationship to cognates in related languages. While etymology can be illuminating, biblical scholars warn against the "etymological fallacy": the mistaken assumption that a word's "true" meaning is its root or earliest sense rather than the meaning it actually carried for its users at the time of writing. How a word was used in its own period — its semantic range in context — is a more reliable guide to meaning than its history.
Eutychianism
The view (condemned at Chalcedon 451) that Christ's human nature was absorbed into his divine nature, resulting in a single, mixed nature.
Exegesis
Drawing meaning out of a text through careful analysis of its language, grammar, historical context, and literary genre.
exemplar
An exemplar is the particular manuscript that a scribe copied from — the immediate source lying open in front of the copyist as he worked. Features of an exemplar, such as its line lengths, abbreviations, or marginal glosses, can leave tell-tale traces in the copy, helping scholars reconstruct the relationships between manuscripts. The exemplar is thus the link in the chain of transmission immediately upstream of any given copy.
F
Formal equivalence
A translation philosophy that aims to stay as close as possible to the form of the original — its words, word order, and grammatical structures — even at some cost to natural style in the receiving language; it is often summarized as "word-for-word." Translations toward this end of the spectrum (such as the NASB, ESV, or the older KJV and ASV) help readers see the underlying wording but can preserve foreign idioms that sound stilted or obscure in English. It is conventionally contrasted with dynamic equivalence, though in practice every translation mixes both approaches.
Functional Christology
An approach that defines Jesus' identity in terms of what he does (his role, function, authority) rather than what he is (his ontological nature). Biblical Unitarians often argue that NT Christology is primarily functional, and that asking "Is Jesus God?" misses the point the NT authors are trying to make, since they seem to be concerned primarily with proclaiming Jesus to be the exalted King/Lord, God's Messiah.
G
Genitive
A grammatical case whose central idea is description, source, or possession — broadly answering "of what?" or "whose?" In Greek the genitive is remarkably broad, covering possession, kinship, content, separation, and many descriptive relations (subjective, objective, attributive, partitive, and more), so that "the love of God" can mean either God's love or love for God depending on context. Hebrew expresses comparable relations chiefly through the construct state rather than a distinct case ending.
gloss
A gloss is an explanatory note — a definition, synonym, or comment — written in the margin or between the lines of a manuscript to clarify a difficult word or phrase. Such notes sometimes slipped into the body of the text when a later scribe mistook the margin for an omitted word and copied it in, creating a kind of interpolation. Detecting glosses that have intruded into the text is a recurring task in textual criticism.
H
Hapax legomenon
A Greek phrase ("something said once") for a word that occurs only a single time in a given body of text — for instance, only once in the Hebrew Bible or only once in the New Testament. Because there are no other occurrences to compare, the meaning of a hapax legomenon often has to be reconstructed from context, etymology, and cognate languages, which makes such words a frequent source of translation disagreement.
harmonization
Harmonization is a scribal tendency to alter one passage so that it matches a parallel passage elsewhere — most commonly aligning the wording of one Gospel with another, or a quotation with its Old Testament source. It is a species of assimilation and usually produces a secondary reading, since scribes were more apt to smooth differences away than to create them. Recognizing harmonization helps editors prefer the reading that diverges from the parallel as likely original.
Hendiadys
A figure of speech (Greek, "one through two") in which a single idea is expressed by two words joined with "and," rather than by a noun plus a modifier. For example, tohu wabohu in Genesis 1:2 ("formless and void") may function as a hendiadys meaning something like "formless waste."
Hermeneutics
The theory and methodology of interpretation, especially of biblical texts. How you read matters as much as what you read.
Homoiousios (ὁμοιούσιος)
"Of similar substance." The position held by the homoiousian party in the 4th century, who affirmed the Son was genuinely divine and like the Father in essence, but stopped short of saying "identical" substance. Often closer to pre-Nicene Logos Theology than to either Nicaea or Arianism.
Homoousios (ὁμοούσιος)
"Of one/same substance." The key term adopted at the Council of Nicaea (325) to express that the Son shares the same divine essence as the Father — not merely similar, but identical in being.
Hyperbole
Deliberate exaggeration for emphasis or effect, not meant to be taken with flat literalness (Greek, "overshooting"). Jesus uses it pointedly — a camel passing through a needle’s eye, or a plank in one’s own eye versus a speck in another’s (Matt 7:3) — to drive a truth home through vivid overstatement. It is the rhetorical opposite of litotes, which understates.
Hypostasis (ὑπόστασις)
Literally "that which stands under." In Trinitarian theology, it came to mean "person" — the three hypostaseis (Father, Son, Spirit) share one ousia (essence). Confusingly, in earlier usage hypostasis and ousia were near-synonyms, which caused significant controversy.
I
Idiom
An expression whose meaning cannot be deduced by adding up the literal senses of its individual words — for example, the Hebrew phrase rendered "to cover the feet" is a euphemism for relieving oneself, and "uncircumcised of lips" means "unable to speak well." Idioms pose a recurring translation challenge: a word-for-word rendering may be unintelligible or misleading, so translators must often choose between preserving the foreign image and conveying the intended sense (see formal equivalence and dynamic equivalence). When such an idiom is carried over literally into another language it can produce a calque or a Semitism.
Imperfective
A category of verbal aspect that presents an action as ongoing, in progress, repeated, or habitual — viewed from the inside, like a film rather than a snapshot. In Greek this aspect is carried by the present and imperfect tenses, and in Hebrew chiefly by the yiqtol (prefix) conjugation. It stands in deliberate contrast to perfective aspect (e.g., the aorist), and like all aspect it concerns the portrayal of an action rather than its absolute time.
Inclusio
A structuring device (Latin, "enclosure") in which the same word, phrase, or motif appears at both the beginning and end of a literary unit, framing it like a pair of bookends. The repeated frame signals where a passage starts and stops and often highlights its central theme; Psalm 8 illustrates this by opening and closing with "O LORD, our Lord, how majestic is your name in all the earth!" (Ps 8:1, 9). It is closely related to chiasm, which extends the same mirroring principle to a passage’s interior.
Indefinite article
The English words "a" or "an", which mark a noun as non-specific or newly introduced ("a man" rather than "the man"). Crucially, neither ancient Greek nor Biblical Hebrew has an indefinite article, so the absence of the definite article — the anarthrous state — is the nearest equivalent. Because of this, English translators must add or withhold "a/an" from context, and an article-less Greek noun can be rendered "a god," "God," or "divine" depending on the interpreter's judgement — the crux of the long-running debate over John 1:1.
Interpolation
A later addition inserted into an existing text. The Comma Johanneum (1 John 5:7–8) is the most famous christological interpolation.
J
Jussive
A Hebrew volitional verb form expressing a third- (and sometimes second-) person wish, command, or permission — "let him," "may it," "let there be" — as in "let there be light." It is closely related to the yiqtol (prefix conjugation), from which it is often indistinguishable in form, sometimes appearing in a slightly shortened spelling. Together with the first-person cohortative and the imperative, it forms the Hebrew system of volitional moods.
K
ketiv
Ketiv (Aramaic for "what is written") denotes the consonants as actually written in the Hebrew text of the Masoretic Text, in cases where the Masoretes wished a different word to be read aloud. In such places the written consonants (the ketiv) are preserved untouched, while the intended pronunciation is supplied by the vowel points and a marginal note — the qere, "what is read." The ketiv/qere system let the scribes flag a corrected or preferred reading without altering the sacred consonantal text.
Koine (κοινή)
The "common" (Greek koinē, "shared") form of Greek that served as the everyday lingua franca of the eastern Mediterranean from roughly the time of Alexander the Great through the early Roman period. It is the dialect in which the New Testament and the Septuagint were written — a simpler, more widely accessible Greek than the earlier classical Attic of authors like Plato — which is part of why the early Christian message could spread so broadly. Its biblical form is also marked by numerous Semitisms reflecting its authors' Hebrew and Aramaic background.
Kyrios (κύριος)
Greek for "Lord." Its usage for Jesus is debated: does it identify him with YHWH (as the Septuagint uses kyrios for God's name), or does it designate him as an exalted agent given authority by God?
L
lacuna
A lacuna is a gap in a manuscript where the text has been lost — through physical damage such as a torn or decayed page, a missing leaf, or faded ink. Many of the oldest witnesses survive only in fragments riddled with lacunae, so a single manuscript may attest some verses of a book and not others. Editors note in the apparatus where a witness is lacunose and therefore cannot testify to a reading.
lectio difficilior
Lectio difficilior ("the more difficult reading") is a guiding principle of textual criticism holding that, between two variant readings, the harder or more awkward one is often more likely original — because scribes tended to smooth out difficulties rather than create them. The fuller maxim is lectio difficilior potior, "the more difficult reading is the stronger." It is a rule of thumb, not an absolute: the harder reading must still make sense and cannot simply be a copying blunder.
Lexeme
The abstract unit of vocabulary that groups together all the inflected forms of a single word — the form one would look up in a dictionary. The English run, runs, ran, and running are all forms of one lexeme RUN; likewise the many forms a Greek verb or Hebrew noun takes are gathered under one lexeme (its "lemma" or dictionary headword). The distinction matters because a word's semantic range belongs to the lexeme as a whole, even though any single occurrence shows just one inflected form.
Litotes
A form of understatement that affirms something by negating its opposite (Greek, "plainness, simplicity"). When Paul calls himself a citizen of "no insignificant city" (Acts 21:39) he means a notable one, and "not a few" means many — the negative phrasing quietly strengthens the claim. It is the mirror image of hyperbole, gaining emphasis through restraint rather than excess.
Logos (λόγος)
Greek for "Word," "Reason," or "Rational Principle." In John 1:1, the term used for the pre-creation entity that "was with God and was God." Trinitarians identify the Logos as the eternal second person of the Trinity; Biblical Unitarians read it as God's plan, purpose, or wisdom personified; Logos theologians see a genuinely divine but subordinate being produced by the Father.
M
majuscule
A majuscule is a manuscript written entirely in large, capital-style letters; in New Testament studies the term is frequently used as a synonym for uncial. The contrast is with the later minuscule hand of smaller, connected letters. Majuscule and minuscule thus describe two broad eras of Greek bookmaking, with the changeover occurring around the ninth century.
Masoretes
The Masoretes were Jewish scribes and scholars, active roughly between the sixth and tenth centuries, who safeguarded the Hebrew Bible by developing systems of vowel points (since the original script wrote only consonants), cantillation accents, and extensive marginal notes known as the Masorah. Their meticulous counting of letters and words, and their preservation of traditional readings such as the qere and ketiv, produced the Masoretic Text. Building on a consonantal text that had already been largely standardized in earlier centuries, their distinctive achievement was to fix the pronunciation of the Hebrew Scriptures and to preserve and transmit that consonantal text faithfully for later generations.
Masoretic Text
The Masoretic Text (abbreviated MT) is the authoritative Hebrew text of the Jewish Scriptures as standardized and transmitted by the Masoretes, medieval Jewish scribes who added vowel points, accents, and marginal notes to a consonantal text that had been carefully preserved for centuries. It is the basis for nearly all modern translations of the Old Testament, though scholars also compare it against the Septuagint and the Dead Sea Scrolls, which occasionally preserve older or different wordings.
Merism
A figure of speech that expresses a totality by naming two contrasting or extreme parts of it (Greek, "division"). The opening of the Bible, "the heavens and the earth" (Gen 1:1), is a merism for the entire created order, just as "going out and coming in" denotes the whole of one’s daily life. Such paired extremes frequently appear within the matched lines of Hebrew parallelism.
Metonymy
A figure of speech (Greek, "change of name") in which something is referred to not by its own name but by the name of something closely associated with it. Biblical examples include "the throne" for royal authority, "Moses and the Prophets" for the Scriptures (Luke 16:29), or "the cup" for what it contains. It is often paired with its close cousin synecdoche, which substitutes a part for the whole.
Miaphysitism
The view (held by Oriental Orthodox churches) that Christ has one united nature that is both divine and human — distinct from Eutychianism (which says the natures are mixed/absorbed) and Chalcedonian dyophysitism (which maintains two distinct natures).
Middle Platonism
The philosophical tradition (c. 80 BC – AD 220) that influenced early Christian theology, especially Logos theology. Key concepts include the distinction between the transcendent God and a mediating divine principle (Logos/Nous) through which God interacts with creation.
Middle Voice
A Greek grammatical voice — alongside active and passive — in which the subject is portrayed as specially involved in or affected by the action, often acting on, for, or with reference to itself ("he washed himself," "she chose for herself"). It has no exact English equivalent, so translators render it variously, and in several tense-forms the middle and passive share identical endings, requiring context to distinguish them. Verbs occurring only in this form with active meaning were traditionally called deponent.
minuscule
A minuscule is a manuscript written in a smaller, joined-up (cursive) script that became the dominant book hand from roughly the ninth century onward, gradually replacing the older uncial style. Minuscules vastly outnumber the uncials and papyri, but most are later copies, so age and quality matter more than sheer numbers when weighing witnesses. Many transmit the Byzantine text-type.
Modalism
The view that Father, Son, and Holy Spirit are not distinct persons but three modes or manifestations of one divine person. Also called Sabellianism (after Sabellius, c. AD 220). In modern form, this is most often represented by Oneness Pentecostalism.
Monarchianism
The umbrella term for early theologies that emphasised the "monarchy" (sole rule) of God the Father. Two types: Dynamic Monarchianism (Jesus is a spirit-empowered human) and Modalistic Monarchianism (Father, Son, and Spirit are modes of one person).
Monogenēs (μονογενής)
Usually translated "only-begotten" (KJV) or "one and only" / "unique" (modern translations). Used of Jesus in John 1:14, 18; 3:16, 18; 1 John 4:9. The translation is debated, but each of the four positions can accommodate either rendering. Trinitarians read it as supporting eternal generation within the Godhead. Logos theologians read it as the Father producing the Son before creation. Biblical Unitarians read "begotten" straightforwardly — Jesus is God's Son, uniquely conceived by God's power (Luke 1:35), the one-of-a-kind Son in a literal sense. Oneness theology commonly reads it in incarnational terms, with Son-language tied to God's manifestation in flesh rather than a second eternal person. The "uniqueness" rendering can be used by all four positions.
Morphology
The study of the internal form and structure of words — how roots, stems, prefixes, suffixes, and inflectional endings combine to signal grammatical information such as tense, case, gender, number, and person. In the biblical languages morphology carries an enormous load: a single Greek or Hebrew word can encode what English needs several words to express, so "parsing" a form is a basic interpretive skill. It is the natural complement to syntax, which addresses how such words then combine.
N
Nestorianism
The view (condemned at Ephesus 431) that Christ consisted of two separate persons — one divine, one human — loosely conjoined. Whether Nestorius himself actually held this view is debated.
Nominative
The grammatical case of the subject — the person or thing performing the action or being described — and the form in which nouns are listed in dictionaries. In Greek the nominative also serves as the predicate nominative after linking verbs such as "to be," renaming the subject (as in "the Word was God"). Hebrew lacks a distinct nominative ending, relying instead on word order and verb agreement to identify the subject.
O
Ontological
Relating to the nature of being itself. "Ontological equality" means two things share the same fundamental nature of being; "ontological subordination" means one is lesser in its very nature. A key distinction in Christology: is Jesus' subordination to the Father merely functional (role-based) or ontological (nature-based)?
Ousia (οὐσία)
Greek for "essence," "substance," or "being." In Trinitarian theology, the one shared divine ousia is what unites the three persons (hypostaseis). The Council of Nicaea declared the Son to be of the same ousia as the Father.
P
papyrus
A papyrus is a writing material made from the pith of the papyrus reed, and the term also denotes a manuscript written on it. The earliest surviving copies of New Testament texts are papyri, often fragmentary, conventionally cited with a gothic "P" and a number (for example, the small fragment of John known as P52). Because of their early date, the papyri are prized witnesses, though their fragmentary state means most preserve only portions of a book.
Parallelism
The defining feature of Hebrew poetry, in which two (or more) successive lines correspond to one another in thought, grammar, or rhythm rather than in rhyme. Scholars classically distinguish three broad types: synonymous parallelism, where the second line restates the first ("The heavens declare the glory of God; the skies proclaim the work of his hands," Ps 19:1); antithetic parallelism, where it states a contrast; and synthetic parallelism, where it advances or completes the thought. Devices such as merism frequently operate within these paired lines.
Participle
A verbal adjective — a hybrid form that retains verbal features (tense/aspect, voice) while also functioning like an adjective or noun (it can take gender, number, and case). In Greek, participles are exceptionally common and versatile, expressing time, cause, condition, means, or attendant circumstance relative to a main verb; their aspect (aorist, present, perfect) is usually more significant than absolute time. Hebrew likewise has participles that can function adjectivally, substantivally, or to denote ongoing or imminent action.
Patristic
Relating to the Church Fathers (Patres) — the influential Christian writers and theologians of roughly the 1st–8th centuries, whose works shaped Christian doctrine.
Perfective
A category of verbal aspect — not tense — that presents an action as a complete whole, viewed from the outside without regard to its internal stages, like a snapshot rather than a film. In Greek this aspect is borne chiefly by the aorist, and in Hebrew by the qatal (suffix) conjugation. It is defined by contrast with imperfective aspect, which views action as ongoing or in progress; aspect concerns how an action is portrayed, which is logically separate from when it occurred.
Perichoresis
"Mutual indwelling" or "co-interpenetration." The Trinitarian concept that the three persons of the Godhead mutually indwell one another, sharing a dynamic communion of being. Used to explain how three persons can be one God without confusion or separation.
Periphrasis
A roundabout way of saying something, substituting a descriptive phrase for a plain name or expression (Greek, "speaking around"). In Scripture it often shows reverence or avoids the sacred name of God — e.g. saying "heaven" for God, as in Matthew’s "kingdom of heaven," or "the Blessed One" for God. The device overlaps with reverential metonymy and can produce a wordiness akin to pleonasm.
Personification
A figure of speech in which an inanimate object, abstract quality, or non-human entity is given human attributes, speech, or behaviour. The Bible has mountains skip, the deep cry out, and — most famously — Wisdom depicted as a woman who calls aloud in the streets (Prov 8:1). When applied specifically to God in human terms it shades into anthropomorphism.
Peshitta
The Peshitta is the standard Bible of the Syriac-speaking churches, written in Syriac (a dialect of Aramaic); its name means "simple" or "common." The Old Testament was translated from Hebrew, while the New Testament Peshitta became the received Syriac version. Because its Old Testament rests on a Hebrew base, the Peshitta serves as a valuable witness alongside the Masoretic Text and Septuagint.
Pleonasm
The use of more words than strictly necessary to express an idea (Greek, "excess"), where the surplus adds emphasis rather than new information. Hebrew idiom is full of it — "he opened his mouth and taught them" (Matt 5:2), or "answered and said" — phrasing that sounds redundant in English but is a natural rhetorical fullness in the original. It is distinct from periphrasis (indirect naming) and the opposite tendency from ellipsis (omission).
Pneumatology
The study of the Holy Spirit — its nature, person, and work. Relevant to Christology because the question of whether the Spirit is a third divine person (Trinitarian) or God's power/presence (Unitarian) parallels the Christological debate.
Polish Brethren
A 16th–17th century anti-Trinitarian Christian community in Poland, influenced by Faustus Socinus. They produced the Racovian Catechism (1605) and maintained that Jesus was a human being, not a pre-existent divine person. Expelled from Poland in 1658.
Pre-Nicene
The period of Christian history before the Council of Nicaea in 325 AD. All pre-Nicene writers who maintained a real distinction between Father and Son held subordinationist views of Christ's relationship to the Father — including those with the highest Christologies, such as Ignatius of Antioch and Irenaeus of Lyon. None articulated the co-equality later defined at Nicaea. The modalists (Noetus, Praxeas, Sabellius) avoided subordinationism only by denying any real distinction between the persons. Also called "Ante-Nicene."
Predicate
In grammar, the part of a clause that says something about the subject — typically the verb together with whatever completes it. A "predicate nominative" or "predicate adjective" is a noun or adjective linked to the subject by a copula (a linking verb such as "to be"), renaming or describing it, as in "the Word was God." In Greek, distinguishing the subject from the predicate noun in such equative clauses — often by which one carries the article — is a recurring point of exegetical attention.
Proof-texting
The practice of citing isolated Bible verses to support a doctrine without attending to their literary context, original audience, or the author's broader argument. All three positions can be guilty of this.
Proskyneō (προσκυνέω)
Greek for "to bow down" or "to worship." The word is used for both worship of God and respectful obeisance to human authorities in the NT. Whether proskyneō directed at Jesus constitutes divine worship is a key point of debate.
Q
Qatal
One of the two main Hebrew finite verb conjugations, formed by adding pronominal suffixes to the verb stem and traditionally called the "perfect" or suffix conjugation. Its core function is perfective — presenting an action as complete or as a whole — and it commonly corresponds to English past tenses, though it can also express present states (especially with stative verbs) and, in certain contexts, future or modal senses. It stands in systematic contrast to the prefix conjugation, yiqtol.
qere
Qere (Aramaic for "what is read") is the word the Masoretes intended to be read aloud where it differs from the consonants actually written in the text. Rather than change the written consonants — the ketiv — they signaled the correct reading through the vowel points placed on those consonants and a note in the margin. Reasons for a qere ranged from suspected scribal errors to euphemism and the reverent substitution made for the divine name.
R
recension
A recension is a deliberate, systematic revision of a text — an edition produced when a scholar or community works through the available copies and establishes a corrected or standardized form. The term is used both for the editorial activity and for its result; for example, scholars speak of recensions of the Septuagint made to align it more closely with the Hebrew. A recension differs from ordinary copying in that it reflects intentional editorial judgment rather than accidental change.
redaction
Redaction is the editorial shaping of source material into a finished work — the activity of the redactor, who selects, arranges, and adapts existing traditions to express a particular emphasis. Whereas a recension revises the wording of an existing text, redaction concerns how an author or editor composed the work in the first place, and "redaction criticism" studies the distinctive theological angle this reveals. The term belongs more to the study of a book's composition than to the copying of its manuscripts.
Referent
The actual person, thing, or idea in the world (or in the discourse) that a word or expression points to — distinct from the word's sense or meaning. A pronoun's referent is identified through its grammatical antecedent, but the term applies broadly: "the Lamb," "the city," and "he" all have referents the interpreter must determine. Establishing the correct referent is often where translation and exegesis quietly do much of their work.
S
Sabellianism
See Modalism.
scribal
Scribal is the adjective describing whatever pertains to the copyists (scribes) who reproduced texts by hand before printing. Textual critics distinguish scribal errors — unintentional slips such as skipping a line or confusing similar letters — from deliberate scribal changes such as harmonization or the insertion of a gloss. Understanding typical scribal habits is central to judging which reading is most likely original.
Second Temple Judaism
The period and religious practice of Judaism between the rebuilding of the Temple (516 BC) and its destruction (AD 70). This is the theological world in which Jesus and the earliest Christians lived, and understanding its categories (agency, exaltation, divine intermediaries) and contemporary writings (Sirach, Wisdom of Solomon, 1 Enoch, etc.) is essential for interpreting NT Christology.
Semantic range
The full set of distinct senses that a single word can carry across its various uses — its "spread" of possible meanings. A given lexeme rarely maps onto exactly one word in another language; the Hebrew ruaḥ and Greek pneuma, for instance, each range over "wind," "breath," and "spirit," so context must decide which sense is in play and translators cannot always preserve the ambiguity. Identifying a word's semantic range, rather than fixing on a single "literal" meaning, is fundamental to responsible exegesis and translation.
Semitism
A feature of vocabulary, grammar, or phrasing in Greek (or another language) that reflects the influence of Hebrew or Aramaic underneath it — a "Hebraism" or "Aramaism" specifically. The Greek of the Septuagint and parts of the New Testament is full of Semitisms, such as "and it came to pass" or "son of man," which arise when a Hebrew idiom is carried over as a calque. Scholars study Semitisms both to understand the texts' style and to probe whether a Greek passage may rest on an earlier Semitic source.
Septuagint (LXX)
The Greek translation of the Hebrew Bible, produced from the 3rd century BC. The NT authors frequently quote from the LXX rather than the Hebrew text. Significant because the LXX uses kyrios (Lord) to translate the divine name YHWH, which becomes relevant when NT authors apply kyrios to Jesus.
Shaliach (שָלִיחַ)
Hebrew for "sent one" or "agent." In Jewish law, "a man's agent is as himself" — an agent speaks and acts with the full authority of the sender without being the sender. Biblical Unitarians argue this principle explains how Jesus could exercise divine authority without being God (see Exodus 23:20–22).
Shema
The foundational Jewish declaration of faith from Deuteronomy 6:4: "Hear, O Israel: the LORD our God, the LORD is one." Some scholars (notably N.T. Wright, followed by Bauckham) argue that Paul "splits" the Shema in 1 Corinthians 8:6, distributing "God" to the Father and "Lord" to Jesus, thereby including Jesus within the divine identity. This reading is relatively recent — it gained prominence only in the 1990s — and is contested. The two passages share only three words (heis, theos, kyrios), in a different order, and Paul explicitly identifies "one God" as "the Father."
Socinianism
The theological movement named after Faustus Socinus (1539–1604), who held that Jesus was a human being, not a pre-existent divine person. Socinians rejected both the Trinity and the satisfaction theory of atonement. The movement was centred among the Polish Brethren. Modern Biblical Unitarianism shares the core Christological stance.
Soteriology
The study of salvation — how it is achieved and what it involves. Relevant to Christology because different views of who Jesus is have implications for how his death functions: Does salvation require a divine sacrifice? Can a human mediator accomplish what Trinitarian soteriology claims? Each position has a different answer.
Subordinationism
The view that the Son is in some way subordinate to the Father. "Ontological subordinationism" (the Son is lesser in being) was the dominant pre-Nicene view and is rejected by post-Nicene Trinitarianism. "Functional subordinationism" (the Son willingly submits in role while being equal in essence) is accepted within mainstream Trinitarian theology, though debated.
Synecdoche
A figure of speech (Greek, "taking together") in which a part stands for the whole or, less often, the whole for a part. When the Bible says "all flesh" to mean all living creatures or all humanity, or speaks of earning bread to mean earning a livelihood (Gen 3:19), it is using synecdoche. It is a special case of metonymy, narrowed to part-and-whole relationships.
Syntax
The branch of grammar concerned with how words combine into phrases, clauses, and sentences — the rules and patterns of word order, agreement, and grammatical relationship — as distinct from morphology, which deals with the form of individual words. Because Greek and Hebrew rely on different syntactic strategies (Greek leaning on case endings and flexible order, Hebrew on word order and constructions like the construct chain), attention to syntax is essential for accurate translation. Many interpretive disputes turn not on vocabulary but on how the clauses of a sentence are construed to relate.
T
Targum
A Targum is an Aramaic translation or paraphrase of the Hebrew Scriptures, originally produced for Jewish communities who spoke Aramaic rather than Hebrew. Targums often expand on the text with interpretive additions, so they shed light on early Jewish exegesis as much as on the underlying wording. Because they range from fairly literal to heavily paraphrastic, scholars use them cautiously as textual witnesses.
Tetragrammaton (יהוה)
A Greek term ("four letters") for the personal name of God in the Hebrew Bible, written with the four consonants yod-he-waw-he (יהוה, conventionally transliterated YHWH). Out of reverence, Jewish readers traditionally do not pronounce it but substitute Adonai ("my Lord"), which is why most English Bibles render it as the small-capital "Lord"; the popular vocalization "Jehovah" arose from combining the consonants of YHWH with the vowels of Adonai, while many scholars reconstruct the original as "Yahweh." The name is closely tied to the theophoric elements found in many biblical personal names.
textual apparatus
The textual apparatus (Latin apparatus criticus) is the dense set of notes — usually at the foot of the page in a critical edition — that records where the manuscripts disagree and which witnesses support each variant reading. It uses a compact system of sigla (symbols and abbreviations) to cite manuscripts, versions, and Church Fathers without taking up excessive space. The apparatus lets readers see the evidence behind an editor's decisions rather than simply trusting the printed text.
Theophany
An appearance or manifestation of God. In the OT, God appears in various forms (burning bush, pillar of cloud, angelic visitors). Whether these are appearances of the pre-incarnate Logos (Trinitarian/Logos view) or of God the Father through agents (Unitarian view) is debated.
Theophoric
Describing a personal name that incorporates the name or title of a deity as one of its components (from Greek, "god-bearing"). In the Hebrew Bible, a great many names embed a shortened form of the Tetragrammaton — typically the prefix Yeho-/Jo- or the suffix -yahu/-iah/-jah — so that "Isaiah" means "YHWH is salvation," "Elijah" means "my God is YHWH," and "Jeremiah" means "YHWH exalts"; other names embed El ("God") or, in foreign names, the names of other gods.
Transliteration
The representation of the sounds or letters of one writing system using the characters of another — for instance, writing the Greek ἀγάπη as agapē in Roman letters, so that readers who cannot read the original script can still pronounce the word. This differs from translation, which conveys meaning rather than sound, and from a calque, which translates a phrase part-by-part. Many familiar Bible words — "amen," "hallelujah," "messiah," "baptize" — entered English as transliterations of Hebrew or Greek terms rather than as translations of them.
U
uncial
An uncial is a Greek (or Latin) manuscript written in formal capital letters, the standard book hand for literary texts in the early centuries of Christianity; the term is often used interchangeably with majuscule. Uncial copies of the New Testament generally date earlier than the cursive minuscules that succeeded them, and many of the most weighty witnesses are uncials. They are cited by letters or by numbers prefixed with a zero.
V
variant reading
A variant reading (or simply a "variant") is any point at which the surviving manuscripts of a text differ from one another — a different word, a changed order, an addition, or an omission. Most variants are trivial spelling differences or obvious copying slips, but a small number affect meaning and are the focus of textual criticism. Identifying the variants and the witnesses behind each is the first step in reconstructing the earliest recoverable wording.
Vocative
The grammatical case of direct address — the form used when calling or speaking to someone, as in "O Lord" or "Father." In Greek the vocative is sometimes distinct in form and sometimes identical to the nominative, and it stands grammatically apart from the rest of the sentence. Hebrew has no vocative case but achieves the same effect through context, the particle of address, or the definite article on the noun being addressed.
Vorlage
A German term (literally "that which lies before") for the source text a scribe or translator was working from. When the Septuagint differs from the Hebrew we have today, scholars ask whether the translator rendered a different Hebrew Vorlage or simply interpreted the same text differently.
Vulgate
The Vulgate is the Latin translation of the Bible largely produced by Jerome around the turn of the fifth century, which became the dominant Bible of the Western Church for over a millennium. Its name comes from the Latin editio vulgata, the "commonly used edition." Jerome translated much of the Old Testament directly from Hebrew rather than the Septuagint, making the Vulgate an important early witness to the Hebrew text of his day.
W
Waw-consecutive
A distinctive Hebrew construction in which the conjunction waw ("and") is prefixed to a verb to carry forward a sequence of past narrative events — the form wayyiqtol — so that a string of such verbs reads "and he did… and he said… and he went." Although built on the prefix (yiqtol) form normally associated with incomplete action, the waw-consecutive characteristically reports completed, sequential past action, effectively reversing the expected aspect — hence the older label "waw-conversive." A parallel weqatal form attaches waw to the qatal to continue future, habitual, or modal sequences.
witnesses
In textual criticism, a witness is any surviving source that attests to the wording of a biblical text — a Greek or Hebrew manuscript, an early translation (a "version" such as the Vulgate or Peshitta), or a quotation in a Church Father. Editors weigh witnesses by age, geographical spread, and reliability rather than simply counting them, since a handful of early independent witnesses can outweigh hundreds of later copies. Each variant reading in a passage is supported by its own set of witnesses.
Y
Yiqtol
One of the two main Hebrew finite verb conjugations, formed with prefixes (and some suffixes) and traditionally called the "imperfect" or prefix conjugation. Its core function is imperfective — presenting action as ongoing, habitual, or yet to occur — and it commonly carries future, habitual, or modal senses; related volitional forms include the jussive and cohortative. It stands in systematic contrast to the suffix conjugation, qatal, and notably appears in the waw-consecutive narrative form.
