# Open Christian Data

Public domain Christian literature as structured, machine-readable data — for developers and AI training.

Commentary data is trapped in HTML and PDFs. No structured commentary dataset exists on HuggingFace. No per-chapter commentary JSON exists on GitHub.

This dataset processes public domain Christian literature — commentaries, church fathers, confessions, catechisms, devotionals, prayers, sermons — into clean, schema-validated records with full provenance metadata.

**GitHub:** [OpenChristianData/open-christian-data](https://github.com/OpenChristianData/open-christian-data)

## Schema types

| Config | Records | Description |
|---|---|---|
| `commentary` | 109,774 | Verse-level commentary (Matthew Henry, Barnes, Calvin, Wesley, Adam Clarke, Gill, JFB, KD, Treasury of David) |
| `church_fathers` | 70,191 | Patristic quotes indexed by scripture reference — 325 authors (Augustine, Chrysostom, Jerome, Origen, Aquinas...) |
| `bible_text` | 31,086 | Berean Standard Bible — all 66 books, 31,086 verses, CC0 |
| `structured_text` | 13,207 | Paragraph-level blocks from 11 works (Calvin's Institutes, Augustine's Confessions, Pilgrim's Progress, City of God, Chesterton, Thomas à Kempis, MacDonald, Underhill, Milton, Luther's Large Catechism) |
| `topical_reference` | 5,945 | Nave's Topical Bible — 5,322 topics, 76,957 scripture references |
| `reference_entry` | 11,145 | Easton's, Smith's, Hitchcock's Bible Dictionaries + Torrey's New Topical Textbook |
| `catechism_qa` | 3,279 | Question-and-answer catechisms (Westminster Shorter/Larger, Heidelberg, Baltimore #1–3, Luther's Small, Keach's, and more) |
| `doctrinal_document` | 1,331 | Confessions and creeds at clause level (Westminster, Nicene, Chalcedonian, Belgic, Dort, London Baptist 1689, Savoy, and 30+ more) |

| `prayer` | 191 | BCP 1662 Collects (85), BCP 1928 Collects (102), Didache Prayers (4) |
| **Total** | **247,649** | |

## Data format

Every record is a flat JSON object. Six fields are inlined from the source file's metadata:

| Field | Description |
|---|---|
| `_source_id` | Unique identifier for the source work |
| `_source_title` | Title of the source work |
| `_author` | Author name |
| `_contributors` | Translators, editors, and digitizers (array, may be empty) |
| `_schema_type` | Schema type (matches the config name) |
| `_license` | License identifier (`cc0-1.0` or `public-domain`) |
| `_source_url` | Canonical URL for the source |

The remaining fields are schema-specific. All verse references use OSIS format (`Gen.1.1`, `Rom.9.1-Rom.9.5`).

## Usage

```python
from datasets import load_dataset

# Load a specific schema type
commentary = load_dataset("OpenChristianDataOrg/open-christian-data", "commentary")
church_fathers = load_dataset("OpenChristianDataOrg/open-christian-data", "church_fathers")
catechisms = load_dataset("OpenChristianDataOrg/open-christian-data", "catechism_qa")

# Filter by source
matthew_henry = [r for r in commentary["train"] if r["_source_id"] == "matthew-henry-complete"]

# All commentary on a specific verse
rom_8_28 = [
    r for r in commentary["train"]
    if "Rom.8.28" in (r.get("verse_range_osis") or "")
]
```
