Church at Rome

Intro

The most famous church in early Christianity sat in the capital of the empire that crucified Jesus. The Christians at Rome were there before Paul ever arrived, before Peter ever arrived, and before the gospel had a name in Latin. The faith reached the city by ordinary means: pilgrim Jews who had been in Jerusalem at Pentecost (Acts 2:10) carried it home to Rome's substantial Jewish community.

By the late 40s AD the community was visible enough that the emperor Claudius expelled Jews from the city over disturbances "at the instigation of Chrestus" (the Roman historian Suetonius's note), almost certainly a reference to Christ. Aquila and Priscilla, two of Paul's closest co-workers, were among the expelled and Paul met them in Corinth (Acts 18:2).

By 57 AD, when Paul wrote his letter to the Romans, the church there was already known "throughout the whole world" (Rom 1:8). Paul finally arrived around 60 AD, under house arrest. Peter also came to Rome at some point. Both apostles were martyred there under Nero around 64 to 67 AD; tradition has Peter crucified upside-down and Paul beheaded (he could be beheaded rather than crucified because he was a Roman citizen). Clement of Rome, writing around 96 AD, attests both martyrdoms in his letter to the Corinthian church.

From there, the Roman church grew into the leading see of the Latin West, anchored on the joint Peter-Paul foundation. The chain of bishops from Clement onward (Clement, Evaristus, Alexander, Sixtus, and on through twenty centuries) is the historical backbone of Apostolic Succession and of the later Catholic doctrine of papal primacy.

This page lays out the founding, the major timeline, the apostolic-era figures, the persecutions, and the development of Roman primacy through the patristic and medieval centuries.

Quick reply line: "The church at Rome was founded before any apostle got there. Both Peter and Paul finished their ministries and died there. The chain of bishops from Clement onward is documented. That is the foundation the West built on."

In full

The church at the capital of the empire, founded before Paul ever arrived (Rom 1; Acts 28), strengthened by both Peter the Apostle and Paul the Apostle in their final years, and developing through the patristic and medieval centuries into the leading see of the Latin West. The Petrine martyrdom in Rome and the patristic chain from Clement onward supply the historical foundation on which the Catholic doctrine of papal primacy and Apostolic Succession rests.

Founding and early years

• Origin: not by an apostle. Roman Jews present at Pentecost (Acts 2:10) likely carried the gospel back to Rome's substantial Jewish community. By the time Paul wrote Romans (~AD 57), the Roman church was prominent enough to be known "throughout the whole world" (Rom 1:8).
• Claudius's expulsion (AD 49) of Jews from Rome (Suetonius Claudius 25.4, "impulsore Chresto") attests a Jewish-Christian community already large enough to provoke administrative attention. Aquila and Priscilla (Acts 18:2) were among the expelled.
• Paul's epistle (Romans, ~AD 57): the most theologically systematic of Paul's letters, addressed to a church Paul had not founded but planned to visit en route to Spain (Rom 15:24, 28).
• Paul's arrival (Acts 28, ~AD 60): house arrest in Rome; "teaching about the Lord Jesus Christ with all openness, unhindered" (Acts 28:31).
• Peter's arrival: not narrated in canonical Acts, but uniformly attested in patristic tradition (Clement, Ignatius, Irenaeus, Tertullian, Origen). 1 Peter 5:13's greeting "from Babylon" is the standard patristic-coded reference to Rome.
• Joint martyrdom under Nero (~AD 64-67): Peter crucified (head-down by his own request per Origen), Paul beheaded (as a Roman citizen). 1 Clement 5 (c. 96) attests both, written from Rome to Corinth.

Theological impact

Petrine primacy

The claim that the bishop of Rome holds a unique authority because Rome is Peter's see develops gradually in the patristic period. Key texts:

• Matthew 16:18-19 ("you are Peter, and upon this rock I will build My church... I will give you the keys"), the load-bearing text. Catholic, Orthodox, and Protestant readings disagree on whether "this rock" refers to Peter, his confession, or Christ himself.
• Clement (1 Clement, c. 96) writes Corinth with an authoritative tone, though formally as the Roman church not as a sole bishop.
• Irenaeus (Adv. Haer. 3.3.2, c. 180): Rome's "preeminent authority" because of its founding by Peter and Paul; tracing its episcopal succession.
• Cyprian (De unitate, 251): Peter as the unity-of-the-episcopate symbol; ambiguous on Roman primacy specifically.
• Pope Leo I (440-461): systematic theology of Petrine succession.
• Gregory VII (Dictatus papae, 1075): high-medieval maximal papal claims.
• Vatican I (1870): infallibility under specific conditions (ex cathedra).

Roman liturgy and canon

The Roman liturgical tradition produced the Latin Mass (canonized at Trent as the Tridentine rite, reformed at Vatican II as the Novus Ordo), the Roman canon (eucharistic prayer), and the Vulgate scripture (Jerome's translation, commissioned at Rome by Pope Damasus, ~AD 382-405). Jerome's Vulgate became the West's biblical text for over a millennium.

Roman creeds and councils

The Apostles' Creed (in its earliest form, the Old Roman Symbol, c. 2nd century) is a Roman baptismal creed. Rome convened or hosted important councils (Lateran councils, Vatican I, Vatican II) and shaped most major Western doctrinal decisions.

The Roman empire's conversion

Constantine's accommodation (Edict of Milan, 313) and Theodosius's official adoption (380) made the Roman church the imperial church, a status that gave it extraordinary institutional power and that has been debated theologically (the Constantinian shift as either God's providence or a corrupting compromise) since the Reformation.

Modern Rome

Vatican City (sovereign since 1929) is the headquarters of the Catholic Church, the largest single Christian communion (~1.3 billion adherents). St. Peter's Basilica stands on the traditional site of Peter's martyrdom and tomb (archaeological work under Pius XII identified what is widely accepted as Peter's burial site beneath the high altar).

Protestant readings

Protestant theology, while honoring the early Roman church and its martyrs, rejects later Roman developments, the papacy as an office, transubstantiation, purgatory, the Marian dogmas, the Council of Trent's anathemas. The Reformation's stance is ad fontes, return to apostolic sources, rather than rejection of Rome's apostolic beginnings.
