The pre-Christian religious practices of Roman Gaul were characterized by
syncretism of Graeco-Roman deities with their native
Celtic,
Basque or
Germanic counterparts, many of which were of strictly local significance. Assimilation was eased by
interpreting indigenous gods in Roman terms, such as with
Lenus Mars or
Apollo Grannus. Otherwise, a Roman god might be paired with a native goddess, as with
Mercury and
Rosmerta. In at least one case, that of the equine goddess
Epona, a native Gallic goddess was also adopted by Rome. Eastern
mystery religions penetrated Gaul early on, which included the cults of
Orpheus,
Mithras,
Cybele and
Isis. The
imperial cult, centred primarily on the
numen of
Augustus, came to play a prominent role in public religion in Gaul, most dramatically at the pan-Gaulish ceremony venerating Rome and Augustus at the Condate Altar, near
Lugdunum, annually on 1 August.

Louvre Museum Gregory of Tours recorded the tradition that after the persecution under the co-emperors
Decius and Gratus (250–251), the future Pope
Felix I sent seven missionaries to re-establish the broken and scattered Christian communities:
Gatien to Tours,
Trophimus to Arles,
Paul to Narbonne,
Saturninus to Toulouse,
Denis to Paris,
Martial to Limoges and
Austromoine to
Clermont. In the 5th and the 6th centuries, Gallo-Roman Christian communities still consisted of independent churches in urban sites, each governed by a
bishop. Christians experienced loyalties that were divided between the bishop and the civil prefect, who operated largely in harmony within the late-imperial administration. Some of the communities had origins that predated the 3rd-century persecutions. The personal charisma of the bishop set the tone, as 5th-century allegiances for
pagans and Christians switched from institutions to individuals. Most Gallo-Roman bishops were drawn from the highest levels of society as appropriate non-military civil roads to advancement dwindled, and they represented themselves as bulwarks of high literary standards and Roman traditions against the
Vandal and
Gothic interlopers. Other bishops drew the faithful to radical asceticism. Bishops often took on the duties of civil administrators after the contraction of the Roman imperial administration during the barbarian invasions of the 5th century by helping fund building projects and even acting as arbiters of justice in the local community. Miracles attributed to both kinds of bishops, as well as holy men and women, attracted
cult veneration, sometimes very soon after their death. A great number of locally venerated Gallo-Roman and Merovingian saints arose from 400 to 750. The identification of the diocesan administration with the secular community, which took place during the 5th century in Italy, can best be traced in the Gallo-Roman culture of Gaul in the career of
Caesarius, bishop and
Metropolitan of
Arles from 503 to 543. (Wallace-Hadrill). ==Language==
