Augustine's Catalogue of Miracles in City of God, Book 22
Too thin a record to say either way.
The account
In the final book of City of God (c. 426 CE), Augustine of Hippo compiled approximately seventy attested miracle accounts from his own diocese, presenting them as evidence that miracles had not ceased with the apostolic age.

In Book 22 of City of God, written near the end of his life (c. 426 CE), Augustine of Hippo shifts from philosophical argument to empirical catalogue. He complains that miracles are no longer publicized as they should be, and sets out to remedy this for his own region. He collected roughly seventy cases from the diocese of Hippo and nearby cities, including healings of paralysis, blindness, hemorrhage, and demonic possession. For the most notable cases, he compiled libelli (written depositions read aloud to the congregation).
Among the best-documented cases are the seven Cappadocian siblings (Paulus and Palladia) who came to Hippo shaking from a supposed maternal curse. Palladia was reportedly healed at the altar during Easter services, while Paulus had been cured days earlier. Augustine personally witnessed Paulus's cure. Roughly seventy healings in the Hippo area alone were attributed to the relics of St. Stephen brought to North Africa in 416 CE.
The cures clustered around the newly arrived relics, drawing pilgrims to the shrine. Witnesses reported their cures to the bishop, Augustine himself, who gathered the testimony; the cures that were reported were the ones that entered the record. Augustine explicitly criticized Christians who failed to publicize miracles, and he had the libelli read publicly before the congregation.
Reviewer Notes
We weigh a claim on two things, kept separate from the story above.
Assessed by Miracles Jar AI
Unusually well-documented for the period; relic-cult social dynamics provide a powerful natural explanation.
The verdict: Unusually well-documented for the period; relic-cult social dynamics provide a powerful natural explanation. The case is genuinely uncertain — neither easily dismissed nor able to clear the bar of natural explanation.
Reasoning. Augustine is a first-rate intellect and a careful writer who took unusual pains to collect sworn testimony and names. His accounts are closer to firsthand documentation than most ancient miracle claims — the libelli process (written depositions read aloud to the congregation) was unusual in its procedural care, and the documentation methods are the best available for late antiquity. However, all cases were reported to a bishop with both theological and institutional stakes in their authenticity, and the cures are tied to relics of St. Stephen — a known focus of crowd psychology and suggestion effects. No independent verification exists, and the social dynamics (pilgrimage, communal expectation, bishop's authority) would have strongly shaped reporting.
Evidence weighed:
- *Toward authentic:* Augustine collected named witnesses with sworn testimony and had libelli read publicly — an unusually rigorous documentation effort for the 5th century. He explicitly criticizes Christians who fail to publicize miracles; the collection reflects genuine evidentiary intent.
- *Toward natural (strong):* All cures cluster around the newly arrived relics of St. Stephen; relic-pilgrimage sites are classic environments for expectation-driven psychosomatic effects. The arrival of prestigious relics at a pilgrimage site generates intense communal expectation, and expectation is a well-documented driver of both psychosomatic improvement and selective reporting of positive outcomes. Concentration of cures around a new relic is sociologically expected rather than evidentially significant. Only cures are publicized; failures and non-events leave no record.
- *Toward natural:* Accounts were collected by the bishop who was also the chief advocate for their authenticity — a structural conflict of interest.
The social architecture of the relic cult is the necessary context. "Best available" documentation in 420 CE is not the same as meeting modern evidentiary standards. The cases remain interesting as historical and sociological data about early Christian practice, even if the supernatural interpretation cannot be sustained.
Evidence ledger — what the verdict rests on

What would raise this score: Documented recurrence in cases with no expectancy pathway — or records ruling out functional overlay — would raise the meter.
What would lower it: Evidence of symptom relapse, revised diagnosis, or undisclosed treatment would lower the evidence bar.
How this works
We keep two questions apart on purpose — so a thin record can’t make an impossible thing look proven, and a strong record can’t dress up an ordinary one as a miracle. First: Could nature explain it? (taking the account as true for the moment.) The question is whether nature could produce this at all — assuming, for the moment, the events are true as described. Second: is there real evidence it happened? A claim only stands out when both hold up — and we never call anything certain either way. How ratings work →
The natural explanation
The leading natural account for this case is expectation, suggestion & the placebo response. Read what it explains — and where it stops.
