The pope also received the palace of Empress Fausta where the Lateran Palace, the papal seat and residence of the papal administration, would be built. At the Lateran Council, during the schism with the Church of Carthage, Miltiades condemned the rebaptism of apostatised bishops and priests, a teaching of Donatus Magnus.

The former French Catholic Archbishopric of Arles had its episcopal seat in the city of Arles, in southern France. At the apex of the delta (Camargue) of the Rhone River, some 40 miles from the sea, Arles grew under Liburnian, Celtic, and Punic influences, until, in 46 B.C., a Roman military veteran colony was founded there by Tiberius Claudius Nero, under instructions from Julius Caesar. For centuries, the archbishops of Arles were regional leaders in creating and codifying canon law, through councils and synods.

Gaul was an important early center of Latin Christianity during late antiquity and the Merovingian period. By the middle of the 3rd century, there were several churches organized in Roman Gaul, and soon after the cessation of persecution, the bishops of the Latin world assembled at Arles in AD 314. The Church of Gaul passed through three crises in the late Roman period, Arianism, Priscillianism and Pelagianism. Under Merovingian rule, a number of "Frankish synods" were held, marking a particularly Germanic development in the Western Church. A model for the following Frankish synods was set by Clovis I, who organized the First Council of Orléans (511).
