Early Church Fathers — Scripture Citation Index

68,240 passages from 349 Church Fathers, each keyed to the Bible verse it comments on. Drawn from 20,253 distinct works and covering all 66 books.

This is a patristic catena in machine-readable form: given a verse, it returns what the Fathers said about it. Nothing comparable exists as an open dataset — the underlying translations are freely available, but the verse-level alignment is the work, and that is what this releases.

Most-cited Fathers

Some attributions are marked as transmitted through a later compiler, e.g. "Augustine of Hippo ((as quoted by Aquinas, AD 1274))" for passages reaching us via the Catena Aurea. These are kept distinct from direct citations on purpose — filter on the parenthetical if you want first-hand attributions only.

Schema

quotation

Example

from datasets import load_dataset

q = load_dataset("sermonindex/early-church-fathers", "quotation", split="train")
john1 = q.filter(lambda r: r["book"] == "JHN" and r["chapter"] == 1)
for r in john1.select(range(3)):
    print(r["father"], "—", r["source_work"])
    print(r["quotation"][:300], "\n")

Provenance

The patristic texts are the standard nineteenth-century English translations — the Ante-Nicene Fathers and Nicene and Post-Nicene Fathers series edited by Philip Schaff and others — which are public domain, together with other public-domain translations of Bede, Oecumenius and the medieval catenae.

The verse alignment, normalisation of Father and work names, and the range handling are SermonIndex's contribution and are released CC BY 4.0.

Caveats

• —Attribution follows the source editions. Where those editions print a work as by a Father and later scholarship disputes it, the dataset carries the traditional attribution. Treat father as the name the tradition attaches, not a settled scholarly judgement.
• —Coverage is uneven by design: the Gospels, Psalms and Romans are far denser than Chronicles or the minor prophets, because the Fathers wrote more on them.
• —Quotation lengths vary from a clause to several thousand words. Check words before chunking.
