Source texts and scholarly datasets used by Cathedra Institute (SBLGNT, MorphGNT, WLC, OSHB, BDB, Abbott-Smith, STEPBible, WEB, KJV, BSB) carry their own licenses, documented in the sections below. Those licenses apply independently to the underlying works and are not extended or modified by Cathedra’s CC BY 4.0 grant on its own original content.

Content Behind Authentication

Course lesson content — the teaching material inside each course, accessible only after signing in and enrolling — is not covered by the CC BY 4.0 grant above. Lesson content is provided to enrolled users for personal study; reproduction or redistribution in any form requires written consent from Cathedra Institute. The same is true of personal portal data (progress, certificates, AI-assisted formation conversations) and prayer-group content.

Brief quotation under fair use for scholarly purposes — academic citation, research papers, classroom use, theological discussion — is welcomed without prior permission, with attribution to “Cathedra Institute” and a link to the source URL. For longer excerpts, wholesale reproduction, or inclusion in derivative educational products (commercial or non-commercial), please contact [email protected].

AI training crawlers and AI-engine citation tools should not attempt to ingest content behind the login wall by any means. Authenticated paths are provided to enrolled users only.

Greek New Testament Text

SBLGNT — SBL Greek New Testament

Scripture quotations marked SBLGNT are from the SBL Greek New Testament, copyright © 2010 Society of Biblical Literature and Logos Bible Software. Licensed under the Creative Commons Attribution 4.0 International License (CC BY 4.0). Cathedra Institute uses the SBLGNT text unmodified; word-level morphological popovers are driven by the separately licensed MorphGNT dataset and are a presentation layer over the text, not a modification of the text itself. The SBLGNT is provided by its licensors without warranty of any kind.

Greek Morphological Data

MorphGNT

Morphological parsing and lemmatization for the SBLGNT, maintained by the MorphGNT project. Cited per the project’s requested form:

Tauber, J. K., ed. (2017) MorphGNT: SBLGNT Edition. Version 6.12 [Data set].

Distributed under the Creative Commons Attribution-ShareAlike 3.0 license (CC BY-SA 3.0). Cathedra uses MorphGNT data unmodified: each token’s parsing code is stored verbatim in biblical_words.morphology_code and rendered as-is in the interlinear viewer popover. Human-readable parse expansions (e.g., “verb, aorist active indicative, 3rd person singular”) come from the separately licensed STEPBible TEGMC dataset (CC BY 4.0), not from a transformation of MorphGNT.

The interlinear viewer presents MorphGNT data alongside SBLGNT, OSHB, BSB, and lexicon data in a Collection (per CC BY-SA 3.0 §1(b)) rather than an Adaptation: the morphology data appears in unmodified form, joined with other independently-licensed works. The share-alike clause therefore applies to the MorphGNT data itself (which remains CC BY-SA 3.0), not to Cathedra’s surrounding application code.

Hebrew Old Testament Text

Westminster Leningrad Codex (WLC)

The Hebrew text of the Old Testament (Tanakh) is the Westminster Leningrad Codex, a digital critical edition based on the Leningrad Codex B19a manuscript (the oldest complete Masoretic Text). Maintained by the J. Alan Groves Center for Advanced Biblical Research at Westminster Theological Seminary. Distributed in the public domain via OpenScriptures morphhb.

Biblical Aramaic sections (portions of Daniel and Ezra) are included from the same source.

Hebrew Morphology

OpenScriptures Hebrew Bible (OSHB)

Word-level morphological tagging and Strong's number mapping for every word in the WLC. Licensed under Creative Commons Attribution 4.0 International (CC BY 4.0). Maintained by the OpenScriptures project. Cathedra uses OSHB under this license, with the following modifications: morphology codes are augmented by TAHOT extended Strong's during ingest, and Psalm superscriptions are merged into their respective English-numbered verses.

Hebrew Lexicon

Brown-Driver-Briggs (BDB)

A Hebrew and English Lexicon of the Old Testament by Francis Brown, S. R. Driver, and Charles A. Briggs (1906). Public domain. The standard academic Hebrew lexicon of the 20th century and still widely cited. BDB is organized around triliteral roots — each root entry discusses etymology, cognate Semitic languages, and core meaning, with derived lemmas nested inside. Cathedra preserves root context by appending each root's prose to every derived lemma's expandable full entry under a clear "Root √..." heading when the root entry carries scholarly prose.

Digitized XML maintained by OpenScriptures HebrewLexicon, which bridges BDB, Strong's Concordance, and Theological Wordbook of the Old Testament (TWOT) numbering.

Lexicon and Morphology — STEPBible Data

Cathedra Institute uses six datasets from STEP Bible (STEPBible-Data on GitHub) published by Tyndale House Cambridge:

• TBESG — Brief definitions for all Greek Bible words, a corrected modernization of Abbott-Smith's Manual Greek Lexicon of the New Testament
• TAGNT — Greek New Testament text with extended Strong's numbers and morphological tagging across all major critical editions
• TEGMC — Expanded explanations of Greek morphology codes
• TBESH — Brief definitions for all Hebrew and Biblical Aramaic Bible words, a corrected modernization of Brown-Driver-Briggs
• TAHOT — Hebrew Old Testament text with extended Strong's numbers and morphological tagging, including Biblical Aramaic sections
• TEHMC — Expanded explanations of Hebrew morphology codes

These datasets are licensed under Creative Commons Attribution 4.0 International (CC BY 4.0). Cathedra uses them under this license, with the following modifications:

• Lemmas are normalized (NFC Unicode, parenthesized variant forms stripped) for database joining
• Fields are extracted and mapped into Cathedra's data schema (lexicon_entries, biblical_words, src/lib/bible/greek-morph-codes.ts, src/lib/bible/hebrew-morph-codes.ts)
• Hebrew versification is normalized to English (Psalm superscriptions merged into verse 1; Joel, Malachi, and scattered verse numbering shifts applied)
• No content is altered; only structural form
