Apostolic Tradition and the See of Capua
The tradition associated with Priscus presents him as belonging to the first generation of Christian missionaries in Italy. The Catholic Encyclopedia records that 'Christianity, it is said, was first preached at Capua by St. Priscus, a disciple of St. Peter,' placing him at the head of the list of bishops of that city. In this account his episcopate is bound up with the very introduction of the Christian faith to Capua.
Scholars have noted a possible confusion in the sources. In the year 443, a man named Priscus, an exile from North Africa and reputed for great sanctity, was elected bishop of Capua; it has been suggested that popular tradition may have carried this later bishop's name back to the beginning of the episcopal list. The relationship between the apostolic-age founder and the fifth-century African exile remains unresolved in the historical record.
