Rome's Clement ordered Corinth to reinstate its elders
Near the year 100, Bishop Clement of Rome—counted among the Apostolic Fathers—wrote to Corinth after locals deposed their presbyters. His letter insists those elders rule by apostolic appointment, offering an early window into how Roman Christians argued about church order.
Clement of Rome, also called Pope Clement I, was Bishop of Rome in the late first century and is often named the first of the Apostolic Fathers. Little biography survives. Tertullian said Peter ordained him; early lists make him second or third bishop of Rome. Eusebius calls him third bishop and Paul's co-laborer; Irenaeus likewise places him in the succession. He is a saint and mariners' patron, kept on 23 November in Catholic, Anglican, and Lutheran calendars and on 25 November in Eastern Orthodoxy. Irenaeus adds that he followed Anacletus and had known apostles in person.
His only undisputed surviving work is 1 Clement, answering Corinth's deposition of certain presbyters. Clement defends their authority because apostles appointed them. Liber Pontificalis and other lists shuffle Linus, Anacletus, and Clement around Peter in ways that still fuel debate over whether first-century Rome already had a single monarchical bishop or a college of presbyter-bishops. The letter counts as the earliest authentic Christian text outside the New Testament; it mentions persecutions, records Peter's martyrdom, and suggests Paul travelled as far as Spain.
The Shepherd of Hermas mentions a Clement who corresponded with other churches, likely this figure. Later tradition equates him with Paul's coworker in Philippians 4:3. Rome already hosted a large congregation by about 58 when Paul wrote Romans; Nero's persecution after the 64 fire and possible Domitianic pressure framed the community Clement addressed around 96, distinguishing overseers or elders from serving deacons without yet clarifying a sharp bishop-versus-presbyter split. Legend filled the gaps. Apocryphal acts written no earlier than the fourth century claim Trajan banished him to a quarry in the Chersonesus, where he struck water from the ground at a spot marked by a lamb. Shortly before he himself died in 869, Cyril, apostle to the Slavs, carried to Rome some Crimean bones found buried with an anchor on dry land, believing them Clement's; they now lie in the Basilica di San Clemente.
