# Patristic sources

Scripture tells us almost nothing about what became of most of the apostles. Nine of the Twelve
never speak a recorded word, and only one death — James son of Zebedee's, in Acts 12:2 — is reported
in the New Testament at all. Everything else comes from the early church fathers and from later
tradition, and those sources vary enormously in reliability.

This page catalogues what this site actually consults, and how much weight each one carries.

## Why grade traditions rather than repeat them

The traditions about the apostles are not one body of evidence. They range from a letter written
inside living memory of the events to medieval legends invented to explain a relic. Treating them as
equally weighty is the commonest failure in popular writing about the Twelve.

The editor of the standard English Eusebius, Arthur Cushman McGiffert, put the problem plainly in
1890:

> The efforts to derive from the varying traditions any trustworthy particulars as to the apostles
> themselves is almost wholly vain. The various traditions not only assign different fields of
> labor to the different apostles, but also give different lists of the apostles themselves.
>
> — A. C. McGiffert, editorial note on Eusebius, *Church History* 3.1, in *Nicene and Post-Nicene
> Fathers*, Series 2, Vol. 1 (1890)

That is the posture this site takes. A tradition gets named, dated, and graded — not asserted.

## The sources

### 1 Clement (c. AD 96)

A letter from the church at Rome to the church at Corinth, written within roughly thirty years of
Peter's death and while people who remembered him were alive. Chapter 5 sets Peter and Paul before
its readers as recent examples, assuming they already know the story:

> Let us set before our eyes the good apostles: Peter, who because of unrighteous jealousy endured
> not one or two but many trials, and having thus borne witness went to the place of glory that was
> his due.
>
> — 1 Clement 5.3-4 (translated from the Greek)

This is the earliest witness to Peter's martyrdom. Note what it does *not* say: it does not name
Rome as the place, and it says nothing about crucifixion or its direction. Those details come later.

**Reliability: high** for the fact of Peter's death as a witness; silent on the circumstances.

### Eusebius, *Church History* (early 4th century)

The single most important source for early church tradition, because Eusebius quotes writers whose
works are otherwise lost — including Papias (early 2nd century) and Origen (3rd century). For the
apostles specifically, *Church History* 3.1 preserves Origen's account of who went where: Parthia to
Thomas, Scythia to Andrew, Asia to John who "died at Ephesus," and Peter, who "having come to Rome,
was crucified head-downwards; for he had requested that he might suffer in this way."

Eusebius is a collector, and he is not uniformly careful. At 1.13 he relates the Edessa
correspondence with King Abgar and identifies the Thaddaeus sent there as one of **the seventy**,
not one of the Twelve — an identification McGiffert flags as Eusebius's own error, and one that has
been confusing accounts of the apostle Thaddaeus ever since.

**Reliability: high for what he quotes, variable for what he concludes.** Read the footnotes in the
Schaff edition; they grade each tradition and are often more useful than the text.

### Papias (early 2nd century), via Eusebius

Bishop of Hierapolis, whose own writings are lost. Eusebius (*Church History* 3.39) preserves his
statement that Matthew compiled the sayings "in the Hebrew dialect" — the earliest surviving claim
linking Matthew to a written record, later echoed by Irenaeus.

**Reliability: early and valuable, but fragmentary** — we have Papias only in quotation, and what
the "Hebrew dialect" statement actually means has been argued over ever since.

### Irenaeus, *Against Heresies* (late 2nd century)

Bishop of Lyons, and the most valuable single witness after Eusebius because of who he knew. Irenaeus
had seen **Polycarp** of Smyrna in his own youth, and Polycarp "was not only instructed by apostles,
and conversed with many who had seen Christ, but was also, by apostles in Asia, appointed bishop of
the Church in Smyrna" (3.3.4). That is a short chain from the apostles to a surviving text.

He supplies the standard account of how the four Gospels came to be written (3.1.1) — Matthew "among
the Hebrews in their own dialect, while Peter and Paul were preaching at Rome," and John publishing
"during his residence at Ephesus in Asia."

**Reliability: high, with one caution.** Irenaeus is careful about what he saw himself versus what he
was told. His famous story of John fleeing a bath-house at Ephesus is introduced as "there are also
those who heard from him [Polycarp] that..." — a report at one remove, and he says so. Read the
attributions, not just the anecdotes.

### The apocryphal Acts (2nd-4th century)

*Acts of Thomas*, *Acts of Andrew*, *Acts of John* and others, collected in Volume 8 of the
*Ante-Nicene Fathers*. These are religious romances, not histories, and several carry a doctrinal
agenda. The ANF editors' description of the *Acts of Thomas* is representative: a book "held in great
estimation by the heretics of the first and second centuries," whose distinctive teaching was that
Thomas baptized with oil rather than water, condemned in the Decree of Gelasius and grouped with the
disputed books in the Synopsis ascribed to Athanasius.

They are evidence that a tradition existed early, not evidence that its content is true.

**Reliability: low as history, useful as dating** — they tell you when a story was circulating.

One genuinely useful thing they preserve: the *Acts of Thomas* opens by listing the Twelve in
**pairs**, following Matthew's order down to "Matthew the tax-gatherer." It is dependent on Matthew
rather than independent of him — which is exactly its value. It shows how an ancient
reader parsed Matthew's Greek. See [The Twelve](https://the-way.lewy.au/biblical-figures/twelve-apostles/#matthews-list-is-six-pairs-and-english-hides-it).

### Later and medieval traditions

Martyrdom accounts for the more obscure apostles, patron-saint associations, relic histories. Andrew's
X-shaped cross is medieval. Simon the Zealot's supposed mission to Britain has no ancient support.
Thaddaeus as patron of lost causes has no ancient basis at all.

**Reliability: low.** Interesting as devotional history; not evidence about the first century.

## A worked example: Thomas and India

The popular claim is that Thomas evangelised India. The sources, in order:

| Source | Date | Says |
|---|---|---|
| Origen, via Eusebius *H.E.* 3.1 | 3rd c. | **Parthia** — the oldest form |
| Clementine *Recognitions* 9.29; Socrates *H.E.* 1.19 | 4th-5th c. | Parthia |
| Rufinus; Socrates *H.E.* 4.18 | 4th-5th c. | **Edessa** as burial place |
| *Acts of Thomas* | 3rd c. | India (apocryphal romance) |
| "Thomas Christians" self-designation in Kerala | **not traceable before the 8th c.** | India |

McGiffert's note is direct: "Later traditions extended his labors eastward as far as India," and the
Kerala community's name for itself "cannot be traced beyond the eighth century, and is derived,
probably, from a Nestorian missionary."

Parthia is early and comparatively well attested. India is late. The [study on Thomas](https://the-way.lewy.au/biblical-figures/thomas/)
sets it out in that order — and did not, in its first published version, which is why this page
exists.

## Where the texts live, and what each kind can settle

The full texts are held on this project's own storage, each recorded with where it came from, when,
and under what licence. They fall into two groups, and **the difference decides what a citation from
them can support.**

### Translations — for finding a passage and reading an argument

- **Eusebius, *Church History*** — Schaff/McGiffert, *Nicene and Post-Nicene Fathers* Series 2 Vol. 1
  (1890), from [CCEL](https://ccel.org/ccel/schaff/npnf201). Public domain; quotable freely.
- **The *Ante-Nicene Fathers*, Vols. 1-10** — Roberts and Donaldson, in Coxe's American edition, from
  [CCEL](https://ccel.org/ccel/s/schaff/anf01). Public domain. Justin Martyr, Clement of Alexandria,
  Tertullian, Hippolytus, Cyprian, Lactantius, the apocryphal Acts, and Irenaeus.

### Originals — for anything that turns on the actual words

Each was fetched for a specific question rather than collected, and each was checked to contain the
passage before being kept:

| Text | Edition | Fetched for |
|---|---|---|
| Apostolic Fathers, Greek | Kirsopp Lake, corrected | 1 Clement 5.4 on Peter; Ignatius; the Didache |
| Eusebius, *Church History*, Greek | GCS, ed. Schwartz | Melito's canon list (4.26); Origen's canon (6.25) |
| Irenaeus, Latin with Greek fragments | ed. Harvey, 1857 | The 616 variant at Revelation 13:18 (*Adv. Haer.* 5.30.1) |
| Tertullian, Latin | CSEL 47, ed. Kroymann | 1 John 5:7-8 — *Adv. Praxean* 25 |
| Cyprian, Latin | CSEL 3.1, ed. Hartel | 1 John 5:7-8 — *De unitate* 6 |
| Victorinus of Pettau, Latin | CSEL 49, ed. Haussleiter | 2 Thessalonians 2:7, the restrainer |
| Augustine, Latin | *Patrologia Latina* 40 | John 7:53-8:11 — *De coniugiis adulterinis* |

All are uncorrected OCR of public-domain print: reliable for locating a passage and quoting a
phrase, not for a long quotation without checking the page images. Greek OCR of century-old print is
markedly worse than Latin, so search word stems rather than exact accented phrases.

### The rule, and the mistake that produced it

**A translation can establish that a father discusses a passage, and what he argues. It can never
establish which words he used.**

That is not a precaution in the abstract. This site published a claim that a phrase attributed to
Victorinus — "when the church shall have gone out of the midst" — was *not in his text*, on the
strength of the *Ante-Nicene Fathers* rendering "until he be taken out of the way." When Haussleiter's
Latin was fetched, both surviving recensions read *de medio* — literally "out of the midst." The two
Englishings were the same three Latin words, and the claim was withdrawn.

The Latin then showed something the translation could not have: both verbs are impersonal, and no
*ecclesia* stands in either clause, so a rendering supplying "the church" as the subject adds the
disputed term. Reading the original did not simply confirm or deny the claim — it changed what the
question was.

### What is deliberately absent

**Jerome's Prologue to the Canonical Epistles**, wanted for the claim that Jerome defended the Comma
Johanneum there. Migne's *Patrologia Latina* 29 and 30 were both fetched and checked and neither
carries it. The one downloadable text that would is Wordsworth and White's Vulgate of **1937** — too
recent to be public domain by age, so it was not taken. A text being fetchable is not permission to
hold it. It would not have settled the point in any case: the dispute is over *who wrote* the
prologue, which no manuscript decides.

Every patristic claim currently made on this site has been checked against a primary text. Where a
chain of report has a weak link — Irenaeus hearing the John anecdote secondhand, Eusebius passing on
the Abgar story with "they say" — the page saying so is the page you should trust more, not less.
