A historical timeline and doctrinal comparison, from the Day of Pentecost to the Great Schism
The Church that began at Pentecost (Acts 2) and the institution that became the Roman Catholic Church did not follow the same path. One began with the outpouring of the Holy Spirit and the preaching of Acts 2:38; the other developed gradually through Roman political influence, imperial councils, and traditions not found in the New Testament. This study traces both side by side — historically and doctrinally.
The Edict of Milan (313 AD) came roughly 280 years after the crucifixion and resurrection of Jesus (~33 AD). For nearly three centuries, the Apostolic Church spread the gospel, not through political favor, but through the power of the Holy Ghost and the sacrifice of faithful believers. Constantine did not start Christianity; he changed its relationship to the Roman state.
Historical Record
Two parallel histories, one beginning at Pentecost, one developing through Roman politics.
| Date / Period | Apostolic Church Biblical Record | Roman Catholic Historical Development |
|---|---|---|
| 30 AD | Day of Pentecost, The Holy Spirit is poured out. Peter preaches and calls the crowd to repentance, baptism in Jesus' name, and the gift of the Holy Ghost. Three thousand obey (Acts 2:38–41). | — |
| 64–67 AD | Peter and Paul are martyred in Rome under Emperor Nero. Their deaths seal their apostolic witness with blood. | The Roman church would later claim institutional authority based on Peter's presence and martyrdom in Rome, a claim not made in Scripture. |
| 1st–3rd Centuries | The Church spreads through Jerusalem, Judea, Samaria, and to the Gentiles (Acts 8–10). Believers face persecution. Local churches are led by a plurality of elders and bishops (Acts 14:23; Titus 1:5). The Apostles' doctrine is the standard (Acts 2:42). | The bishop of Rome gradually begins claiming greater authority over other bishops. The groundwork for a centralized hierarchy is laid, but the New Testament assigns no such authority to any single bishop or location. |
| 313 AD | — | Edict of Milan, Emperor Constantine and co-emperor Licinius legalize Christianity across the Roman Empire. Church property is restored. For the first time, imperial politics become intertwined with Christian doctrine. |
| 325 AD | — | Council of Nicaea, Called by Constantine to resolve theological disputes. Doctrine begins to be defined by imperial councils using philosophical Greek terminology (homoousios) not found in Scripture. Creeds begin replacing the simplicity of the Acts 2:38 salvation message. |
| 380 AD | — | Edict of Thessalonica, Emperor Theodosius I declares Nicene Christianity the official state religion of the Roman Empire. Christianity is now backed by the full force of imperial law. |
| 4th–6th Centuries | Faithful believers continue in Apostolic doctrine: repentance, baptism in Jesus' name, and the infilling of the Holy Ghost. Though increasingly outside the mainstream of state-backed religion, the original gospel is preserved. | A hierarchical structure emerges: pope, cardinals, bishops, priests. New practices take hold, infant baptism, prayers to Mary and saints, and veneration of relics. These are not found in the New Testament. |
| 590 AD | — | Pope Gregory the Great consolidates papal power and formalizes the structure and authority of the Roman Catholic Church. He is widely regarded as one of the most influential popes in Catholic history. |
| 1054 AD | — | The Great Schism, The Western church (Roman Catholic) and the Eastern church (Eastern Orthodox) formally split over issues of papal authority and doctrine. Christianity has now fractured significantly from the unified body of Acts. |
Doctrines & Practices Compared
Ten key areas where the biblical record and Roman Catholic tradition diverge.
| Topic | Apostolic Church Biblical Record | Roman Catholic Church Historical Development |
|---|---|---|
| Foundation | Built on the apostles' doctrine and Jesus Christ as the cornerstone. Acts 2:42 · Eph. 2:20 | Built on papal authority, with the Bishop of Rome regarded as the successor to Peter and supreme head of the Church. |
| Salvation | Repentance, baptism in Jesus' name, and receiving the Holy Ghost with the evidence of speaking in tongues. Acts 2:38 · Acts 10:44–48 · Acts 19:1–6 | Baptism (including infant baptism), confession, and the seven sacraments — defined and administered by church authority, not solely by Scripture. |
| Baptism | Always performed in the name of Jesus Christ, by full immersion, for the remission of sins. Acts 2:38 · Acts 8:16 · Acts 10:48 · Acts 19:5 | Performed using the titles "Father, Son, and Holy Spirit." Infant baptism and sprinkling became standard practice by the early medieval period. |
| Holy Spirit | Received with the initial evidence of speaking in tongues, recorded every time the infilling is described in Acts. Acts 2:4 · Acts 10:46 · Acts 19:6 | Affirmed as received at baptism and confirmation. Speaking in tongues is no longer considered the required evidence of receiving the Holy Spirit. |
| Leadership | A plurality of elders and bishops in local churches. Apostles traveled to strengthen and establish churches, no single city held supreme authority. Acts 14:23 · Titus 1:5 · 1 Peter 5:1–3 | Hierarchical pyramid: pope, cardinals, bishops, priests. Authority flows downward from Rome. The papacy is not found in the New Testament. |
| Worship | Simple gatherings, breaking bread, prayer, preaching the Word, and the gifts of the Spirit in operation. Acts 2:42–47 · 1 Cor. 14 | Elaborate Latin Mass, incense, icons, statues, formal liturgy, and priestly rituals developed gradually from the 3rd century onward. |
| Prayer | Directed to God through the name of Jesus Christ, no other mediator, no intercession through saints or Mary. Acts 4:24 · John 14:13–14 · 1 Tim. 2:5 | Prayer to God, but also to Mary and deceased saints for intercession, a practice that developed from the 3rd through 5th centuries, with no New Testament basis. |
| Scripture | The Hebrew Scriptures and the Apostles' writings circulated and read among the churches. Scripture is the final authority. 2 Tim. 3:16 · Col. 4:16 · Gal. 1:8 | Scripture plus official Church tradition, papal decrees, and council decisions. The Latin Vulgate became the standard, and for centuries, Scripture was largely inaccessible to ordinary believers. |
| Authority | The Word of God and the apostles' teaching, no creed, council, or emperor required to validate doctrine. Acts 2:42 · 2 Tim. 3:16 | Papal decrees, ecumenical councils, and tradition held equal or greater authority than Scripture. Councils could define, refine, or overrule earlier positions. |
| Focus | Evangelism, holiness, and preparing for the return of Christ. The Church exists to win souls and disciple believers, not to build earthly power. | Sacraments, rituals, and the management of a church-state institution. Earthly hierarchy and papal prestige became central concerns from the 4th century onward. |
The Church Jesus said He would build (Matthew 16:18) began in Acts 2. It was characterized by Spirit-filled believers, baptism in Jesus' name, and the Apostles' doctrine. Scripture, not councils or emperors, was its authority.
"And they continued steadfastly in the apostles' doctrine and fellowship, in the breaking of bread, and in prayers." Acts 2:42 (NKJV)
The Roman Catholic Church did not begin at Pentecost. It developed gradually through imperial influence, philosophical councils, and traditions that introduced doctrines not found anywhere in the New Testament.
"For I know this, that after my departure savage wolves will come in among you, not sparing the flock. Also from among yourselves men will rise up, speaking perverse things." Acts 20:29–30 (NKJV)
Returning to the Standard
The Apostolic message has not changed. Repentance, baptism in Jesus' name, and the infilling of the Holy Ghost, the same gospel Peter preached on the Day of Pentecost — is still the door to salvation. The developments traced above represent a departure from that standard, not a refinement of it.
"But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed." Galatians 1:8 (NKJV)
