It seems to be commonly held among scholars that the so-called monarchical episcopate (i.e. the system of having one bishop governing a city church with presbyters working with him) was not apostolic and did not come to Rome until the late second century or even later. That is the opinion of scholars such as Alistair Stewart (in his commentary Hippolytus: On the Apostolic Tradition), Brent Allen (in his Hippolytus and the Roman Church in the Third Century), and others such as the late great J.N.D. Kelly. By this figuring the Christians in Rome had no one leader who spoke for all of them, but were divided into a number of self-governing communities with different leaders described by various titles. A single leader who could speak for all the communities in Rome only arose in the late second century (with Bishop Victor) or the early third century (with Bishop Pontianus).

Writers such as Irenaeus who asserted there were such singular leaders and bishops in Rome from the days of the apostles were, according to this theory, anachronistically projecting back a later system into an earlier time. It also follows therefore that the document known as the Apostolic Tradition, ascribed to Hippolytus and dating from the early third century, cannot be taken as evidence of a monepiscopate in Rome at that time, but must be regarded as the result of extensive redaction. What are we to make of this? Need we dump that section of Irenaeus’ work?
