Christianity in Gaul
Historical Event
2nd – 6th Century AD Spread of the Church
Key Facts:
- c. 150 AD — a Christian community organized at Lyon
- 177 AD — a persecution at Lyon kills roughly 48 known victims, including the city's first bishop, Pothinus, who dies in prison
- Irenaeus of Lyon, a student of Polycarp of Smyrna, succeeds Pothinus as bishop, organizes missionary efforts across Gaul, and becomes a key early theologian
- By 250 AD, roughly 30 episcopal sees exist, including Lyon, Arles, Marseille, Autun, Vienne, Toulouse, Narbonne, Trier, Reims, and Paris
- Martin of Tours (316–397 AD), a former Roman soldier, founds Gaul's first monasteries (Ligugé, then Marmoutier) and is regarded as the father of Western monasticism; as bishop of Tours he actively destroys pagan temples
Overview:
- The earliest solid evidence of Christianity in Gaul dates to the mid-2nd century AD. The first missionaries most likely arrived by sea via Marseille and progressed up the Rhône to Lyon, which became the region's central hub.
Novel Relevance:
- This is the religious transition Clovis's own conversion (traditionally 496 AD, more likely c. 508 AD per the Avitus correspondence) sits at the tail end of. By his baptism, Gaul already had roughly three and a half centuries of organized Christian presence layered over the older druidic/Celtic religious substrate the series' magic draws from. St. Remigius of Reims, who reputedly baptizes Clovis, stands in this same episcopal lineage.
