History · AD 30–313
Persecution, Martyrdom, and the Growth of the Church
Central question: How did a small, occasionally persecuted Jewish messianic movement grow into a substantial and eventually legally tolerated presence across the Roman Empire?
Where scholarship stands
Historians agree that persecution occurred in identifiable waves (under Nero, Domitian to a lesser extent, Decius, Valerian, and Diocletian) rather than constantly; there is less agreement on exact numbers of martyrs, on how central persecution was to church growth, and on the reliability of individual martyrdom narratives.
Overview
Christianity's legal status in the Roman Empire before 313 was ambiguous. It was never comprehensively outlawed by a single empire-wide statute for most of this period; rather, adherence to Christianity became actionable under existing law because Christians refused participation in the imperial cult and traditional sacrifices, which could be construed as impiety, treason (maiestas), or membership in an illicit association (collegium illicitum). Pliny the Younger's correspondence with Trajan (c. AD 112) shows a governor uncertain of the correct procedure, and Trajan's reply — punish those who persist after being given opportunity to recant, but do not seek Christians out — set a pattern of localized, complaint-driven prosecution rather than systematic manhunt.
The first attributed state persecution came under Nero after the fire of Rome in AD 64; Tacitus (Annals 15.44) describes Christians blamed as scapegoats and subjected to gruesome executions in Rome, though he notably still regards them with contempt as adherents of a 'pernicious superstition.' Whether Nero's persecution extended beyond Rome itself is uncertain. Domitian's alleged persecution (c. AD 95–96), often connected to the book of Revelation's exilic setting, is now regarded by most historians as more limited and localized than earlier scholarship assumed.
The third century saw the first genuinely empire-wide persecutions: Decius's edict of AD 250 required all inhabitants to sacrifice and obtain a certificate (libellus), several of which survive on papyrus from Egypt; Valerian's persecution of 257–260 specifically targeted clergy and Christian property; and the Great Persecution under Diocletian, beginning in AD 303, was the most severe and systematic, involving destruction of churches and scriptures, loss of legal rights, and executions, lasting in various regions until the Edict of Milan in 313 under Constantine and Licinius granted toleration.
Martyrdom accounts (acta and passiones) are a distinctive genre combining historical memory with theological and literary shaping; the Martyrdom of Polycarp (mid-2nd century) is widely regarded as one of the earliest and most historically credible, while later, more elaborate accounts show clear hagiographic embellishment. Candida Moss's The Myth of Persecution (2013) controversially argued that the scale and continuity of persecution have been substantially exaggerated in the church's later self-memory, provoking significant pushback from other historians.
On growth, sociologist Rodney Stark's The Rise of Christianity (1996) modeled plausible exponential growth from a few thousand believers in AD 40 to perhaps six million by AD 300 through ordinary network conversion rates, without requiring mass persecution-driven sympathy, emphasizing instead social networks, care for plague victims, and relatively favorable treatment of women, though Stark's specific demographic model has been questioned on methodological grounds by other historians.
What the evidence shows
- • Real, sometimes severe persecution of Christians occurred under multiple Roman emperors, well documented in both Christian and Roman sources.
- • Persecution before the mid-third century was generally local and complaint-driven rather than systematic empire-wide policy.
- • The Decian, Valerianic, and Diocletianic persecutions were qualitatively different: organized, empire-wide, and administratively documented.
- • Christian numerical growth through the third century is well attested even without assuming any single explanatory mechanism.
What it does not establish
- • It does not establish precise casualty numbers for any period; ancient and modern estimates vary widely.
- • It does not confirm every detail in later, more elaborate martyrdom narratives as historical fact.
- • It does not settle whether persecution helped or hindered church growth on balance.
- • It does not resolve debates over Constantine's personal sincerity.
Timeline
AD 64
Great Fire of Rome and Nero's persecution
Tacitus records Nero blaming and brutally executing Christians in Rome as scapegoats for the fire.
c. AD 64–68
Traditional martyrdoms of Peter and Paul
Later Christian tradition (1 Clement, Eusebius) places both apostles' deaths in Rome under Nero, though precise details are not independently verifiable.
c. AD 95–96
Alleged Domitianic persecution
Later tradition links Revelation's exile setting (Patmos) to persecution under Domitian, though modern historians see this as more limited than once assumed.
c. AD 110–115
Ignatius of Antioch condemned
Bishop of Antioch transported to Rome for execution; his surviving letters reflect anticipation of martyrdom.
c. AD 112
Pliny–Trajan correspondence
Governor Pliny asks Trajan for guidance on prosecuting Christians in Bithynia; Trajan's reply sets a moderate, complaint-driven precedent.
c. AD 155–160
Martyrdom of Polycarp
Bishop of Smyrna executed for refusing to curse Christ and sacrifice to the emperor; an early and relatively sober martyrdom account survives.
AD 177
Persecution at Lyon and Vienne
Eusebius preserves a letter describing brutal public executions of Christians in Gaul, including the deacon Sanctus and the slave Blandina.
c. AD 180
Scillitan Martyrs, North Africa
One of the earliest datable Latin Christian martyrdom accounts, from Roman North Africa.
AD 202/203
Martyrdom of Perpetua and Felicitas
Vivid first-person prison diary attributed to Perpetua, a noblewoman, describing her trial and execution in Carthage.
AD 250
Decius's edict
First empire-wide requirement to sacrifice and obtain a certificate (libellus); many Christians lapsed (lapsi), creating later church controversy over readmission.
AD 257–260
Valerian's persecution
Targets clergy and confiscates Christian property; ends abruptly when Valerian is captured by Persia.
AD 260
Edict of Gallienus
Valerian's son restores Christian property and grants a period of toleration lasting roughly four decades.
AD 303
Great Persecution begins under Diocletian
Edicts order destruction of churches and scriptures, dismissal of Christian officials, and eventually executions across the empire.
AD 311
Edict of Toleration by Galerius
Dying emperor Galerius ends the Great Persecution in the East, asking Christians to pray for him.
AD 312
Battle of the Milvian Bridge
Constantine defeats Maxentius, later attributing victory to a vision associated with the Christian God.
AD 313
Edict of Milan
Constantine and Licinius jointly grant legal toleration to Christianity and restore confiscated property throughout the empire.
Sources & reliability
Every source carries a caution. An argument built on a source you cannot defend is a liability.
Tacitus, Annals 15.44
Roman · c. AD 116
What it says: Describes Nero's brutal persecution of Christians after the fire of Rome in AD 64.
Caution: Written 50 years after the events by a historian hostile to Christianity, though his account is not obviously exaggerated in Christians' favor, which supports credibility.
Pliny the Younger, Letters 10.96–97
Roman · c. AD 112
What it says: Governor's report describing his handling of accusations against Christians and Trajan's moderate reply.
Caution: Reflects one governor's practice in one province, not necessarily universal imperial policy.
Martyrdom of Polycarp
Christian · c. AD 155–170 (composition)
What it says: Firsthand-derived account of Bishop Polycarp's arrest, trial, and execution by burning and stabbing in Smyrna.
Caution: One of the earliest and most sober martyrdom texts, but later manuscript layers show some redactional expansion drawing parallels to Jesus' passion.
Passion of Perpetua and Felicitas
Christian · c. AD 203
What it says: Includes what purports to be Perpetua's own prison diary describing visions and her trial before execution in the arena.
Caution: The framing narrative was added by an editor (possibly Tertullian); authenticity of the first-person diary portion is debated but widely considered plausible.
Eusebius, Ecclesiastical History
Christian · c. AD 313–325
What it says: Preserves earlier martyrdom accounts (Lyon and Vienne, Scillitan Martyrs) and narrates the Great Persecution under Diocletian.
Caution: Eusebius writes as court historian under Constantine with clear providential and apologetic framing of persecution and its end.
Decian libelli (sacrifice certificates)
Archaeological · AD 250
What it says: Surviving papyri from Egypt record individuals certifying they performed the required sacrifice under Decius's edict.
Caution: These documents confirm the edict's administration but say nothing directly about Christians who refused and were punished.
Lactantius, On the Deaths of the Persecutors
Christian · c. AD 313–315
What it says: Narrates the deaths of persecuting emperors (Nero through Diocletian) as divine judgment.
Caution: Explicitly polemical and providential in structure; historical details are used selectively to serve a theological argument.
Rodney Stark, sociological modeling
Christian · Modern scholarship, 1996
What it says: Models Christian growth from a few thousand adherents in AD 40 to millions by AD 300 via ordinary conversion network rates.
Caution: A modern sociological reconstruction based on assumed growth rates, not a primary ancient source; its specific figures are debated by historians.
Live scholarly debates
Was persecution of Christians before Constantine continuous and empire-wide, or sporadic and local?
Sporadic, local, and often overstated in later memory
Candida Moss
Moss's The Myth of Persecution argues that outside the identifiable empire-wide episodes (Decius, Valerian, Diocletian), most persecution was local, brief, and driven by regional tensions rather than sustained imperial policy, and that later Christian memory constructed a narrative of continuous suffering that outran the evidence.
Real and pervasive, even if not continuous
Paul Middleton; other patristic historians
Middleton and others argue that even sporadic, localized persecution produced a pervasive climate of legal vulnerability and social hostility documented across many regions and periods (Pliny, Lyon, Scillium, Carthage), and that Moss underweights how routinely Christians faced real legal and social risk even between major imperial edicts.
What best explains the rapid numerical growth of Christianity in its first three centuries?
Ordinary network-based conversion and social benefits
Rodney Stark
Stark modeled growth using standard rates found in modern new religious movements, arguing no miracle or mass event is needed to reach several million adherents by 300, driven by social networks, care during plagues, and appeal to women given expanded roles relative to pagan norms.
Persecution and martyrdom themselves as a recruiting and cohesion mechanism
W.H.C. Frend
Frend's Martyrdom and Persecution in the Early Church argued that public martyrdom accounts functioned rhetorically to demonstrate the faith's power and attract converts impressed by conviction under threat of death, making persecution paradoxically a contributor to growth rather than simply an obstacle.
How reliable are individual martyrdom acta as historical sources?
A core group is substantially reliable
Herbert Musurillo (editor of standard critical edition)
Musurillo's Acts of the Christian Martyrs identifies a smaller set of texts (Polycarp, Scillitan Martyrs, Perpetua) as close to contemporary court records or eyewitness testimony, distinguishing these from later, more legendary passiones composed centuries after the events they describe.
Even 'early' acta show significant literary shaping
Candida Moss; various form critics
Moss and others argue that even the earliest martyrdom accounts are shaped by imitation of Christ's passion and earlier martyr narratives, meaning their value as straightforward historical record needs to be weighed carefully against their function as theological literature.
Was Domitian's persecution (c. AD 95–96) a major empire-wide event?
Limited and largely a later Christian retrospective exaggeration
Leonard Thompson
Thompson's study of Revelation's historical context argued that Domitian's alleged persecution of Christians is thinly attested outside later Christian sources and likely reflects local tension and perceived rather than actual systematic state persecution.
A real, if smaller-scale, persecution occurred
Adela Yarbro Collins
Collins argues some real hostility and possibly localized persecution under Domitian, connected to emperor-cult refusal, is plausible and provides adequate background for Revelation's language of tribulation, even if it fell short of a systematic empire-wide campaign.
Why did Constantine convert to and promote Christianity?
Sincere religious conversion
Eusebius; Peter Leithart
Eusebius's Life of Constantine and later Christian historians such as Leithart argue Constantine's own testimony (the reported vision before the Milvian Bridge, his subsequent legislation, and personal correspondence) reflects genuine, if theologically unsophisticated, conversion.
Primarily political calculation
Ramsay MacMullen
MacMullen and other historians of Late Antiquity emphasize that Constantine's actions can equally be explained as shrewd politics — co-opting a growing, organized minority for social cohesion and imperial legitimacy — with sincere belief, if present, secondary to political utility.
