Glossary of Greek for Theological Reading

This document is copy & pasted, not written by me

This glossary provides a brief and clear overview of key Greek verb forms and grammatical features often encountered in biblical or theological studies. It is especially designed for non-specialists who want to understand how theologians draw meaning from the original Greek of the New Testament.

1. Imperative Mood

• Definition: The imperative is the mood of command, exhortation, or instruction.
• Example: "Repent" (μετανοεῖτε) - Matthew 3:2
• Use: Often used by Jesus or apostles when issuing commands, moral imperatives, or pastoral instructions.
• Distinction: A present imperative might imply ongoing action ("keep on repenting"), while an aorist imperative often implies a decisive, one-time action ("repent now").

2. Indicative Mood

• Definition: The indicative states facts or reality as perceived by the speaker.
• Example: "Jesus wept" (ἐδάκρυσεν ὁ Ἰησοῦς) - John 11:35
• Use: The most common mood; used for narrative, history, or theological declarations.
• Theological Insight: Statements of Christ’s divinity, the resurrection, and justification are usually in the indicative-affirming these as objective realities.

3. Subjunctive Mood

• Definition: The subjunctive expresses possibility, hypothetical situations, purpose, or conditionality.
• Example: "That they may believe" (ἵνα πιστεύσωσιν) - John 11:15
• Use: Common after ἵνα (hina, "so that") to express purpose or desired outcome.
• Theological Use: Often appears in prayers, hopes, or moral aspirations.

4. Optative Mood

• Definition: The optative expresses wishes, potential, or remote possibility.
• Example: Rare in the NT, but sometimes: "May it never be!" (γένοιτο) - Romans 6:2
• Use: Much rarer than the subjunctive. When used, it can be strong and emotionally charged.
• Note: Paul frequently uses the optative in passionate rhetorical contexts.

5. Present Tense

• Definition: Usually implies continuous or ongoing action.
• Example: "Everyone who keeps on sinning…" (ὁ ποιῶν τὴν ἁμαρτίαν) - 1 John 3:8
• Use: Emphasises character or habitual action, not just a momentary event.
• Theological Note: Present tense is often used to describe a believer’s ongoing lifestyle or relationship with God.

6. Aorist Tense

• Definition: Describes an action as a whole or complete event-not focused on duration.
• Example: "Christ died for us" (ἀπέθανεν) - Romans 5:8
• Use: Often used in narratives or doctrinal statements of decisive past events (e.g., crucifixion, resurrection).
• Theological Note: Important for doctrines like justification, which are seen as completed acts.

7. Perfect Tense

• Definition: Indicates an action that is completed in the past with continuing results in the present.
• Example: "It is written" (γέγραπται) - Matthew 4:4
• Use: Emphasises the lasting significance of a past event.
• Theological Importance: Used often in reference to Scripture and accomplished redemption.

8. Pluperfect Tense

• Definition: Describes an action completed before another past action.
• Example: "For they had seen" (ἑωράκεσαν) - John 6:14
• Use: Less common, used in narrative to establish temporal sequence.
• Theological Use: May emphasise prior knowledge or earlier experience shaping a later event.

9. Future Tense

• Definition: Describes what will happen.
• Example: "You will be saved" (σωθήσῃ) - Romans 10:9
• Use: Promises, prophecies, eschatology.
• Theological Emphasis: Heavily used in promises of salvation, judgment, resurrection.

10. Infinitives

• Definition: The infinitive is the verb form used like a noun, often translated with "to…" (e.g., "to believe").
• Example: "To live is Christ" (τὸ ζῆν Χριστός) - Philippians 1:21
• Use: Functions within clauses as purpose, result, cause, etc.
• Theological Insight: Frequently used in defining doctrinal propositions (e.g., "to be saved", "to justify").

11. Participles

• Definition: Verbal adjectives. Describe action but act like modifiers.
• Example: "Believing in Him" (ὁ πιστεύων εἰς αὐτόν) - John 3:16
• Use: Flexible form-can express cause, time, means, or condition.
• Theological Note: Often express the manner or means of salvation (e.g., "having believed", "being justified").

12. Middle Voice

• Definition: The subject participates in or benefits from the action.
• Example: "He washed himself" (ἐλούσατο) - Acts 9:18
• Use: Sometimes emphasises personal involvement.
• In Theology: Can imply personal engagement in salvation or spiritual practice, though not always.

13. Passive Voice

• Definition: The subject receives the action rather than doing it.
• Example: "You were saved" (ἐσώθητε) - Ephesians 2:8
• Use: Important in expressing God’s action upon the believer.
• Theological Note: Salvation, justification, sanctification are frequently in the passive to highlight divine agency.

14. Active Voice

• Definition: The subject performs the action
• Example: "Jesus heals" (ἰᾶται) - general example
• Use: Emphasises the subject’s role in the action.
• In Doctrine: Often used when describing God’s acts (e.g., "God sent", "Christ died").

15. Deponent Verbs

• Definition: Verbs that are middle/passive in form but active in meaning.
• Example: ἔρχομαι ("I come") - appears middle but functions actively.
• Use: A quirk of Greek. Not indicating passive/middle meaning despite form.
• Helpful Tip: Don’t overread the form-consult a lexicon.

16. Imperfect Tense

• Definition: Past tense with a focus on continuous or repeated action.
• Example: "He was teaching" (ἐδίδασκεν) - Mark 4:2
• Use: Used in narrative to show ongoing past action, often setting the scene or describing habitual activity.
• Theological Insight: Highlights Jesus’ ongoing ministry actions or repeated behaviour of others.

17. Conditional Sentences (First-Fourth Class)

• Definition: Greek has four classes of conditional sentences based on the conjunction εἰ ("if") or ἐάν.
• Examples:
  • First class (assumed true): "If you are the Son of God…" (Matt. 4:3) - εἰ with indicative.
  • Second class (contrary to fact): "If I were still trying to please men…" (Gal. 1:10).
  • Third class (possible future): εάν with subjunctive.
  • Fourth class (less certain, rare): εἰ with optative.
• Theological Insight: These are crucial for understanding promises, warnings, and hypotheticals, especially in soteriology and eschatology.

18. Voice Clarification - Middle Vs Passive in the Future and Aorist

• Greek shares forms between middle and passive in some tenses (especially future and aorist).
• Why it matters: Sometimes translators must decide whether the verb is passive (God acting) or middle (self-involvement).
• Example: βαπτίσομαι - could be "I will baptise myself" (middle) or "I will be baptised" (passive).
• Note: Context is key for interpretation.

19. Periphrastic Constructions

• Definition: A verb phrase made with a form of "to be" (εἰμί) + a participle.
• Example: ἦν γράφων - "he was writing"
• Use: Emphasises continuity or state, especially in present or imperfect tense.
• Why it’s important: Adds nuance; sometimes used to highlight emphasis or intentionality in an action.

20. Articular Participles

• Definition: Participles with a definite article (ὁ, ἡ, τό), used almost like a noun.
• Example: ὁ πιστεύων - "the one who believes"
• Use: Often used for describing categories of people (e.g., "the one who sins," "the one who justifies").
• Theological Note: Vital for doctrines of identity (e.g., believers vs unbelievers).

21. Genitive Absolute

• Definition: A grammatical construction where a noun and a participle in the genitive form a background clause.
• Example: "While he was speaking…" - τοῦ λέγοντος αὐτοῦ
• Use: Adds background information, time markers, or circumstantial descriptions.
• Theological Use: Important in narrative flow; shows sequencing or cause in events.

22. Redundant Pronouns and Emphasis

• Greek sometimes uses redundant personal pronouns to create emphasis, even when the verb already implies the subject.
• Example: ἐγώ εἰμι - "I am" (emphatic)
• Use: Used frequently by Jesus for emphatic identity statements (e.g., "I am the bread of life" - John 6:35).
• Theological Weight: Heightens Christological claims.

23. Historical Present

• Definition: The present tense used to describe past events, especially in narrative.
• Example: "And Jesus says…" (λέγει) - Mark 2:5
• Use: Creates vividness, immediacy, or a sense of ongoing impact.
• Reader’s Tip: Don’t be confused-though it’s in present tense, it refers to past action.
