The Christian city. From the origins of Christianity the community of Capua certainly had an important role, but other than the traditional information on the consecration of the protobishop Priscus by Peter, before the 4th c. the literary and archaeological sources tell us little. Amply attested, however, is the strong connection with Rome, not only through the frequent contact of the prelates of the two sees, but also for the widespread cult of the apostles Peter and Paul, alongside indigenous martyrs. Jakarta Map The Prologus Paschae of 395 refers to the letters lost of a Cyprian, probably bishop of Carthage, to Augustine and Felicita, martyred apud ciuitatem Capuensem under Decius MGH AA, IX, Chronica minora, I,738. In the 4th c., in close connection with its role as a civil metropolis, Capua played an important role in ecclesiastical politics: its titular, Proterius, participated in the synods of Rome of 313 and Arles of 314, and his church, with that of Naples, was one of the only two in all of S Italy to benefit from a direct intervention by the emperor Constantine, who built a basilica dedicated to the Apostles intra urbe Capua LP I,185-186. The episcopal see of Capua played a leading role during the Arian crisis, as a mediator between Rome and the Eastern episcopates. Its bishop, Vincent, perhaps to be identified with the presbyter who represented Sylvester of Rome at the Council of Nicaea, is cited twice in the Apologia of Athanasius to Constantius PG 25,595- 641. He participated at the Council of Serdica of 343; in 344 he was sent on a mission to Antioch to Constantius to mitigate the emperor’s anti-Nicene measures; in 353 he was present as a Roman legate at the Council of Arles, where he was forced to subscribe to the condemnation of Athanasius, and in 357 Liberius, during his exile at Terracina, asked him to intervene with the emperor on his behalf.
