Theological Vocabulary of the Epistle to the Greeks
O sweet exchange! O unsearchable workmanship! O unexpected benefits! (Greeks 9:5)
This study examines the theological vocabulary of the Epistle to the Greeks, chapters 7–9, to test a specific hypothesis: that the epistle's mid-second-century rhetorical style wraps around theological content drawn from an earlier tradition. The main article on the epistle (The Epistle to the Greeks) argues for this dual-dating model on qualitative grounds, the παῖς/υἱός Christological alternation, the absence of the Holy Spirit, the raw Pauline atonement theology unprocessed by later frameworks. This study tests the same hypothesis quantitatively, by classifying every theological term in the epistle's densest section and mapping its chronological distribution across the Greek patristic corpus.
🔗Method
Every theologically weighted term in chapters 7–9 was extracted from Holmes's third-edition critical text and classified into one of four chronological buckets based on its distribution in the surviving Greek corpus:
- Bucket A: Pre-Christian. Terms available to any educated Greek writer before Christianity existed. Classical philosophical vocabulary, Hellenistic moral terminology, standard literary Greek. These carry no chronological signal for the text's theological tradition.
- Bucket B: Early Christian. Terms whose theological application peaks in the New Testament and the Apostolic Fathers (roughly 50–130 CE) and is absent or exceptionally rare in the extant mid-second-century Apologists (Justin Martyr, Theophilus of Antioch, Athenagoras). The classification is based on the theological sense of the word, not the bare lexeme, many Bucket B terms exist in classical Greek but are deployed in a specifically Christian soteriological register that the surveyed Apologists did not use or used only exceptionally.
- Bucket C: Transitional. Terms that straddle the first-to-second-century boundary, appearing in both early Christian and later patristic usage without a clear chronological break.
- Bucket D: Second-century apologetic. Terms characteristic of the mid-second-century Greek Apologists: the technical philosophical vocabulary of Justin, Theophilus, and Athenagoras: Logos Spermatikos, Endiathetos/Prophorikos, developed homologia formulas, and the wider theological lexicon that emerged as Christianity engaged Middle Platonism.
Classification used four primary reference works: BDAG (A Greek-English Lexicon of the New Testament and Other Early Christian Literature), Lampe's Patristic Greek Lexicon (which tracks the full chronological distribution of every term across the Greek church fathers), the Theological Dictionary of the New Testament (TDNT), and LSJ (A Greek-English Lexicon). The Patrologia Graeca corpus (16,000+ works) and Lampe's citation chronology provide the comparison data for each Bucket B assignment, including occurrences in Justin, Theophilus, and Athenagoras and gaps between the Apostolic Fathers and later patristic writers.
The text was divided into two zones: the cosmological frame (7:1–8:4), where the author introduces God's nature and the sending of the Son, and the theological core (8:5–9:6), where the atonement argument unfolds. This division tests whether the vocabulary profile differs between the apologetic framing and the soteriological content.

🔗Combined Distribution
Across both zones: 54% Bucket A, 28% Bucket B, 16% Bucket C, 0% Bucket D.
🔗Comparison with Mid-Second-Century Apologists
Each Bucket B term is compared with the three major mid-second-century Apologists — Justin Martyr (~150 CE), Theophilus of Antioch (~180 CE), and Athenagoras (~177 CE) — using the Patrologia Graeca corpus and Lampe's citation chronology. The comparison takes each author's genuine works as its base; divine-patience language in the spurious pieces printed under Justin's name in volume 6 (the Liber de Monarchia and the Quaestiones ad Graecos) is therefore not counted as Apologist use.
| Term | Justin | Theophilus | Athenagoras | Lampe gap |
|---|---|---|---|---|
| λύτρον (lutron, "ransom") | Absent | Absent | Absent | Diogn. 9:2 → Irenaeus, Haer. 5.1.1 (~180) → Clement of Alex. (~200) (Lampe); Melito, Pascha 103 (~170, Asianic rhetor) is cited by BDAG, with λουτρόν in the Bodmer witness |
| χρηστότης (chrēstotēs, "kindness") | Once only: Dialogue 47:5, quoting the Titus 3:4 formula | Absent | Absent | 1 Clement → Clement of Alex., Origen |
| μακρόθυμος (makrothymos, "long-suffering") | Absent | Twice of God: Ad Autolycum 2.26, 2.37 | Absent | Barnabas, 1 Clement → Gregory of Nyssa (~380 CE) in Lampe's citations (~250-year citation gap; Theophilus' uses are not cited there) |
| φανερόω (phaneroō, "reveal") | Once of God: Dialogue 75.4, πεφανερῶσθαι τὸν θεόν | Three located: Ad Autolycum 2.11, 2.19, 2.23, of the creation/formation account, not God's self-revelation | None located in the genuine Legatio or De Resurrectione (targeted verb-form checks; not exhaustive) | Lampe's "of God" citations: Barn. 12:8, Ign. Magn. 8:2, 2 Clem. 20:5, Diogn. 8:11, Just. Dial. 75.4; next cited at Clement of Alex. |
| ἀνεξιχνίαστος (anexichniastos, "unsearchable") | Absent | Absent | Absent | Irenaeus, Haer. 1.2.2 (reporting the Valentinians) → 4th century |
Across these rows, the theological deployment of each term is absent or exceptional in the three surveyed Apologists: outside the quoted Titus 3:4 formula (χρηστότης in Justin), one theophany use (φανερόω in Justin), and two divine-attribute uses (μακρόθυμος in Theophilus), no further uses in the classified theological senses were located in their extant genuine works. The later record is term-specific: λύτρον is cited by Lampe from Irenaeus (Haer. 5.1.1, ~180) before Clement of Alexandria (~200 CE), ἀνεξιχνίαστος occurs in Irenaeus's report of the Valentinians, and the adjective μακρόθυμος is next cited by Lampe only in Gregory of Nyssa (~380 CE). The table therefore supports a comparison with the extant apologetic corpus, not a gap extending to all surviving mid-second-century Christian writing.1
🔗What the Data Show
🔗The absence of Bucket D vocabulary
The most striking result is not the presence of early Christian vocabulary but the complete absence of second-century apologetic vocabulary. Of the fifty-seven theological terms classified across both zones, not one belongs to the lexical stratum characteristic of the mid-second-century Apologists.
This absence is significant because the epistle is itself an apologetic work addressed to a pagan audience, precisely the genre in which one would expect the apologetic vocabulary of the author's own era to surface. Justin, Theophilus, and Athenagoras were writing for similar audiences with similar goals. Yet the theological tools the author of Greeks reaches for come from a different lexical era.
A purely conservative second-century author remains possible in principle, a writer who preferred older, scriptural vocabulary over the philosophical terminology of his contemporaries. However, the cumulative profile makes simple conservatism a less economical explanation than the preservation of earlier tradition. The author avoids not just a few trendy terms but the entire standard theological vocabulary of his era. The παῖς/υἱός alternation is particularly telling: by the mid-second century, παῖς θεοῦ for Christ had fossilized into a fixed liturgical formula, almost always the stereotyped phrase "through Jesus your Child" in prayers.2 A conservative writer in 150 CE would naturally use υἱός, the established orthodox title. The author of Greeks deploys παῖς in free theological argument with distinct soteriological functions, not conservatism but a vocabulary that predates the fossilization.
🔗The concentration in the soteriological core
The Bucket B terms are not scattered randomly across the text. Their main concentration is the atonement argument of 8:9–9:5, where the author presents the mechanics of salvation; adjectival μακρόθυμος falls just before that passage, at 8:7. The section deploys λύτρον (ransom, the Markan atonement term), the χρηστότης + φιλανθρωπία pairing (which echoes Titus 3:4), μακροθυμέω (9:2; divine patience, an LXX attribute of God), ἀνεξιχνίαστος (unsearchable, from Job 5:9/9:10 via Romans 11:33), the filial παῖς (pre-fossilization Christology), and φανερόω (the Pauline/Johannine revelation verb).
No single term in this list carries decisive chronological weight on its own. Some of these words exist in classical Greek; their force as chronological markers depends on the specific theological sense in which the author deploys them. But the coordinated pattern — a tightly clustered set of early-Christian soteriological terms and formulations, with no corresponding uptake of known second-century apologetic vocabulary — is stronger than any individual data point. The theological core of the epistle exhibits a lexical profile more at home in the soteriology of the New Testament and the Apostolic Fathers than in the theological discourse of the extant mid-second-century Apologists.3
🔗The cosmological frame
The frame section (7:1–8:4) shows a different profile: 61% Bucket A vocabulary, reflecting the author's classical philosophical education, with 22% Bucket B. This is consistent with the dual-dating model, the frame is where the mid-second-century rhetor's own intellectual world is most visible. The Bucket B terms that do appear (παντοκράτωρ, ἀόρατος, πραΰτης) are drawn from early Christian creedal and liturgical language, suggesting the author inherited these formulas rather than generating them.
The author's single candidate hapax — παντοκτίστης (pantoktistēs, "creator of all," 7:2) — sits in the frame, not the core. This is the one place where the author's own word-making plausibly surfaces. The word is cited by BDAG and Lampe from this verse alone, is absent from LSJ, and no earlier reuse than Andrew of Crete (five hundred years later) was located in the searched corpora; he appears to have coined a new compound to describe God's creative power, pairing it with the inherited παντοκράτωρ. The apparent coinage is itself second-century Asianic rhetoric; the theological concept it expresses is not.
🔗The Dual-Strata Model
The vocabulary mapping supports a specific version of the dual-dating hypothesis: not two physically distinct text layers, but two chronologically distinct vocabulary strata within a single composition.
- The theological source material exhibits the lexical profile of first-century Christian soteriology: early-Christian vocabulary with strong Pauline and Johannine resonances, including terms absent or exceptionally rare in the extant mid-second-century patristic evidence.
- The rhetorical carrier — a mid-second-century Asianic rhetor with a Hellenistic philosophical education — contributes the protreptic genre, the Asianic prose style, the cosmological framing vocabulary, and at least one probable coinage (παντοκτίστης).
- What the carrier did not do: update the theological vocabulary. He transmitted the soteriology with its original lexical profile relatively intact, including terms (λύτρον, μακρόθυμος, filial παῖς) that the surveyed Apologists of his own era did not use or used only exceptionally.
This does not require the recovery of a specific written source document. The mechanism may be catechetical tradition, inherited kerygmatic formulas, earlier homiletic material, or a prior textual tradition now lost, any channel through which first-century theological diction could reach a second-century rhetor without passing through the apologetic vocabulary of his contemporaries. The observation is lexical, not redactional: whatever rhetorical recasting occurred, the theological diction appears resistant to lexical updating.4
The classifications in this study admit some judgment calls at the margins, a few terms could plausibly shift between Bucket B and Bucket C without altering the overall picture. Even if every contestable Bucket B assignment were moved to Bucket C, the theological core would remain free of positive Bucket D markers, and the concentration of early-type soteriological diction in the atonement argument would persist. The zero-D finding is stable under modest reclassification.
🔗Notes
1 Lampe, G. W. H. A Patristic Greek Lexicon. Oxford: Clarendon Press, 1961. The gap analysis uses the earliest dated citation for each term's theological sense to identify periods where the term is absent from the lexicon's chronological record. Lampe covers the full Greek patristic corpus from the Apostolic Fathers through John of Damascus (~749 CE); the Patrologia Graeca digital corpus (161 volumes, 16,000+ works) supplies the comparison texts for Justin, Theophilus, and Athenagoras.
2 W. Zimmerli and J. Jeremias, "παῖς θεοῦ," in Theological Dictionary of the New Testament, ed. G. Kittel and G. Friedrich, trans. G. W. Bromiley, vol. 5 (Grand Rapids: Eerdmans, 1967), 654–717. "παῖς θεοῦ for Christ survived after the NT only as a fixed liturgical formula anchored in the eucharistic prayer, the doxology and the confession" (p. 700).
3 The term "extant" is important. The surviving mid-second-century Greek Christian corpus is thin, largely apologetic in genre, and absence of a term from surviving texts does not prove absence from the language of the period. The argument rests on the cumulative pattern documented across multiple terms and reference works, not on any single lexical absence.
4 The parallel is instructive: the Didache is widely recognized as a second-century Greek redaction of first-century Jewish-Christian tradition ("there seems to be a general consensus that the 'two ways' material in chaps. 1–6 has a prehistory that connects with Jewish ethical concerns"; AYBD, s.v. "Didache"), and the Odes of Solomon preserve deeply Johannine, pre-institutional theology in later manuscripts ("most specialists who have published a detailed comparison conclude that the Odes are earlier or contemporaneous with the gospel of John"; AYBD, s.v. "Solomon, Odes Of"). In both cases, a later literary frame transmits older theological content without fully updating the vocabulary. The author of Greeks appears to operate in the same tradition-historical mode.
