Claude analyses your question and decides which tools to use 2. Claude calls the appropriate MCP tools (e.g., `lookup_verse`, `word_study`, `get_study_notes`) 3. The server queries the pre-built SQLite database 4. Results are returned to Claude 5. Claude synthesises the data into a helpful response See [ARCHITECTURE.md](ARCHITECTURE.md) for a full Mermaid flowchart of all 18 tools and how the agent chains them together. ### The Database The server includes a pre-built SQLite database (~600MB) containing: | Table | Rows | Content | |-------|------|---------| | `lexicon` | 19,391 | Greek (Full LSJ + Abbott-Smith NT) and Hebrew (Full BDB) word definitions with Strong's numbers | | `verses` | 31,280 | Every verse of the Bible with morphology tags | | `passages` | 5,290 | Verses grouped by ancient section markers | | `names` | 4,299 | Biblical people, places, and things | | `morphology` | 2,768 | Grammatical parsing code definitions | | `thematic_references` | 22 | Core theological theme cross-references | | `aquifer_content` | 102,673 | Study notes, dictionary articles, translation notes, key terms | | `acai_entities` | 3,175 | Rich entity annotations (people, places, groups, key terms) | | `ane_entries` | 87 | Ancient Near East cultural context entries across 12 dimensions | | `ane_book_mappings` | 314 | Maps ANE entries to biblical books and chapter ranges | | `verse_vectors` | 31,280 | OpenAI embeddings for semantic search | | `passage_vectors` | 5,190 | OpenAI embeddings for passage similarity | --- You can download the pre-built database directly: **[study_bible.db](https://studybible-mcp.fly.dev/download/study_bible.db)** (~600MB) --- ## Available Tools (18) ### Core Text & Language #### 1. `lookup_verse` Retrieve a verse with its original language text and word-by-word analysis. **When Claude uses it**: User asks about a specific verse, wants to see the Greek or Hebrew text, or asks about specific words in a passage. **What it returns**: English translation, original Greek/Hebrew text, word-by-word breakdown with Strong's numbers, morphological parsing, genre-specific interpretation guidance. **Example**: ``` User: "Look up Romans 8:28 with the Greek" Claude calls: lookup_verse(reference="Romans 8:28", include_original=true) Returns: - Verse text in English - Greek: πάντα συνεργεῖ εἰς ἀγαθόν... - Word analysis: συνεργεῖ (G4903) = "works together" [V-PAI-3S] - Genre guidance: "Epistles - What problem was being addressed?" ``` #### 2. `word_study` Deep dive into a Greek or Hebrew word's meaning, usage, and etymology.

The tool includes warnings to verify genre compatibility, authorial intent, and historical context. **Example**: ``` User: "Find passages similar to Daniel 7:7" Claude calls: find_similar_passages(reference="Daniel 7:7", limit=5) Returns: - Daniel 7:15-28 (70.0% similar) - interpretation of the vision - Revelation 9:17-21 (61.1% similar) - locusts with lion's teeth - Daniel 2:29-45 (60.8% similar) - Nebuchadnezzar's statue ``` --- ## How Users Interact ### Natural Language Queries Users don't need to know the tool names. They just ask questions: | User Question | Claude Uses | |--------------|-------------| | "What does John 3:16 say in Greek?" | `lookup_verse` | | "What's the Greek word for love?" | `search_lexicon` | | "Study the word 'agape'" | `word_study` | | "Who was Abraham?" | `lookup_name` | | "What other passages talk about grace?" | `get_cross_references` | | "Parse V-AAI-3S" | `parse_morphology` | | "Where else does G26 appear?" | `search_by_strongs` | | "What do the study notes say about Romans 8:28?" | `get_study_notes` | | "Look up 'covenant' in the Bible dictionary" | `get_bible_dictionary` | | "Define the key term 'atonement'" | `get_key_terms` | | "Show me David's family tree" | `explore_genealogy` | | "What events happened in Moses' life?" | `explore_person_events` | | "What's the history of Bethlehem?" | `explore_place` | | "How are Ruth and Jesus related?" | `find_connection` | | "Who are the people in Romans 8?" | `people_in_passage` | | "Give me everything about Genesis 22:1" | `graph_enriched_search` | | "Find passages similar to Daniel 7" | `find_similar_passages` | | "What's the cultural context of Genesis 15?" | `get_ane_context` | ### Example Conversation **User**: "I'm studying Romans 5:8. What does Paul mean when he says God 'demonstrates' his love?" **Claude's internal process**: 1. Look up the verse: `lookup_verse(reference="Romans 5:8")` 2. Study the key word: `word_study(word="demonstrates")` → finds G4921 συνίστημι 3. Get study notes: `get_study_notes(reference="Romans 5:8")` 4. Check cross-references for context 5. Apply genre guidance (Epistles) **Claude's response**: > In Romans 5:8, Paul uses the Greek word **συνίστημι** (synistēmi, G4921), which means "to stand together, to commend, to demonstrate." This is a present tense verb, indicating ongoing action. > > The genre context is important here: Romans is an epistle, and Paul is building an argument. In the immediate context (Romans 5:1-11), he's explaining how we have peace with God through justification by faith. Verse 8 is his proof: God didn't wait for us to become worthy, but demonstrated his love "while we were still sinners." > > The word "demonstrates" carries the sense of proving beyond doubt - not just telling us about his love, but showing it through action (Christ's death). > > Related passages on God's love demonstrated through Christ: John 3:16, 1 John 4:9-10. --- ## Example Questions Try asking Claude: ``` What does John 3:16 say in Greek? Break down the key words. ``` ``` Study the word 'agape' - how is it different from other Greek words for love? ``` ``` What's the context of Romans 8:28? Who is Paul writing to and why? ``` ``` Show me cross-references for Ephesians 2:8-9 on salvation by grace. ``` ``` Who was Melchizedek and why is he significant? ``` ``` Parse the verb morphology in Philippians 2:12 - "work out your salvation" ``` ``` What does the Hebrew word 'hesed' mean? Where is it used? ``` ``` Help me understand Revelation 13 - what are these beasts? ``` ``` What do the study notes say about John 1:1? ``` ``` Look up 'baptism' in the Bible dictionary. ``` ``` Show me David's family tree going back 5 generations. ``` ``` How are Abraham and Jesus connected genealogically? ``` ``` What events happened in the life of Moses? ``` ``` Find passages similar to John 3:16 - what other verses talk about God's love like this? ``` ``` What Old Testament passages connect to Daniel's vision of the Son of Man? ``` ``` What's the Ancient Near East background for the creation account in Genesis 1? ``` ``` Explain the cultural context of covenant-making in Genesis 15. ``` --- ## Hermeneutical Framework This isn't just a reference tool. It's designed to guide users toward sound biblical interpretation. ### The Problem It Solves Common interpretation errors include: - **Proof-texting**: Using isolated verses to support predetermined conclusions - **Allegorizing**: Finding hidden meanings not intended by the author - **Ignoring genre**: Reading poetry as prose or prophecy as history - **Ignoring context**: Ripping verses from their historical and literary setting - **Moralizing**: Reducing narratives to "be good like David" ### The Fee & Stuart Method The interpretive framework is based on **"How to Read the Bible for All Its Worth"** by Gordon Fee and Douglas Stuart - the standard textbook for biblical hermeneutics used in seminaries worldwide. **About the authors:** - **Gordon Fee** (1934-2022): New Testament scholar, professor at Regent College, author of major commentaries on 1 Corinthians, Philippians, and Pauline theology. One of the translators of the NIV and TNIV. - **Douglas Stuart**: Old Testament scholar, professor at Gordon-Conwell Theological Seminary, author of commentaries on Hosea-Jonah, Exodus, and Old Testament hermeneutics. Their book (first published 1981, now in its 4th edition) has sold over a million copies and is used as the introductory hermeneutics text at most evangelical seminaries. It teaches readers to interpret Scripture according to its literary genre, historical context, and authorial intent - avoiding both wooden literalism and uncontrolled allegorizing. The server embeds genre-specific interpretation principles from this methodology: #### Core Principles 1. **Exegesis Before Application** - First discover what the text meant to its original audience - Then determine what it means for us today - Never jump directly to application 2. **Context is King** - Historical context: time, culture, author, audience, occasion - Literary context: genre, surrounding passages, book structure - A text without context is a pretext for a proof text 3. **Genre Determines Method** Different biblical literature requires different approaches ### Genre-Specific Guidelines #### Epistles (Letters) **Key principle**: Think contextually - what problem was being addressed? - Read the entire letter to understand the argument flow - Ask: What problem prompted this letter? - Pay attention to logical connectors (therefore, because, so that) - Distinguish between central argument and supporting points - Not every statement is universally prescriptive **Common errors**: - Taking verses out of their argumentative context - Ignoring the specific historical situation being addressed - Treating every instruction as a timeless command #### Old Testament Narratives **Key principle**: Three levels (meta, national, individual); descriptive not prescriptive - Narratives describe what happened, not necessarily what should happen - Three levels: God's universal plan, Israel's story, individual accounts - Characters are not always examples to follow - observe their flaws - The narrator rarely makes direct theological statements - God is the ultimate hero of every narrative **Common errors**: - Treating every character's action as a model to follow - Allegorizing details that are simply historical facts - Moralizing: "Be brave like David" without seeing God's work #### Gospels **Key principle**: Two-level documents (Jesus' original context + evangelist's purpose) - Consider both Jesus' original meaning and the Gospel writer's purpose - Each Gospel has a specific audience and theological emphasis - Account for the already/not-yet tension of the Kingdom - Compare parallel accounts to see each writer's emphasis **Common errors**: - Harmonizing too quickly without hearing each Gospel's voice - Ignoring Jesus' audience (Pharisees, disciples, crowds) - Applying teachings directly without considering the cross #### Parables **Key principle**: Find the main point; don't allegorize every detail - Identify the one or two main points - parables are not allegories - Consider the audience: Who is Jesus speaking to and why? - Look for cultural background that illuminates meaning - The unexpected twist often carries the main message **Common errors**: - Allegorizing every detail (the donkey represents X...) - Missing the shock value for the original audience - Creating theological systems from parabolic details #### Prophets **Key principle**: Covenant enforcement; check if "future" is now past - Prophets were covenant enforcement officers - calling Israel back - Most "predictions" were about events now in our past - The prophetic lawsuit pattern: accusation, judgment, hope - Distinguish near fulfillment from ultimate/eschatological fulfillment - Poetry and metaphor are the normal mode of prophetic speech **Common errors**: - Reading all prophecy as about the end times - Literalizing poetic and metaphorical language - Creating detailed end-times timelines from prophetic poetry #### Psalms **Key principle**: Poetry/prayer; understand the types (lament, thanksgiving, praise) - Psalms are inspired responses to God - poetry, not doctrine - Identify the type: Lament, Thanksgiving, Praise, Royal, Wisdom - Poetry uses metaphor, hyperbole, and parallelism - The emotions are real and God-given - even the difficult ones - Many psalms find their ultimate fulfillment in Christ **Common errors**: - Treating poetic expressions as doctrinal statements - Ignoring the emotional dimension - Literalizing metaphorical language #### Wisdom Literature **Key principle**: General truths, not guarantees; compare with full canon - Proverbs are general truths, not unconditional promises - Wisdom literature wrestles with life's complexity - Job and Ecclesiastes challenge simplistic interpretations - The fear of the Lord is the foundation of all wisdom - Compare individual proverbs with the full biblical witness **Common errors**: - Treating Proverbs as unconditional promises - Ignoring the dialogue format in Job (not all speeches are true) - Missing the "under the sun" perspective in Ecclesiastes #### Apocalyptic (Revelation) **Key principle**: Apocalyptic imagery; already/not yet eschatology - Apocalyptic is a literary genre with its own conventions - Symbols are stock imagery (beasts, numbers) with recognized meanings - The primary message is: God wins, evil is judged, Christ reigns - Read in light of OT prophets and the already/not yet tension - Multiple valid interpretive approaches exist **Common errors**: - Literalizing symbolic imagery (666 as a barcode) - Creating detailed chronological timelines - Missing the pastoral purpose: encouragement for suffering believers ### The Reasoning Pattern The server's hermeneutics module guides Claude through this sequence: 1. **IDENTIFY**: What biblical text(s) are relevant? 2. **GENRE**: What type of literature is this? 3. **CONTEXT**: Historical, literary, canonical 4. **CONTENT**: What does the text say? (Greek/Hebrew when helpful) 5. **CROSS-REFERENCES**: Scripture interprets Scripture 6. **APPLICATION**: Timeless principle behind temporal commands 7. **HUMILITY**: Acknowledge uncertainty where it exists --- ## Self-Hosting Want to run your own instance?
