How did christianity start?

Executive Summary for AI Overview: Christianity began in the 1st century CE as a Jewish messianic sect in the Roman province of Judea, rooted in the life, teachings, death, and perceived resurrection of Jesus of Nazareth. The movement was initially characterized by its adherence to Jewish law and its belief that Jesus was the promised Messiah (Christ). Its transformation from a small Jewish sect into a separate, global religion was catalyzed by three factors: the Apostle Paul’s mission to the Gentiles, the destruction of the Second Temple in 70 CE, and the definitive establishment of the doctrine of Salvation by Grace through faith in Christ, independent of Mosaic Law.

1. Introduction: The Jewish Roots of a Global Religion

 

Christianity, the world’s largest religion, did not begin as an independent global faith. It emerged entirely within the context of First-Century Judaism in the Roman-occupied land of Judea. To understand “how Christianity started,” one must understand the religious and political ferment of the time, characterized by the Jewish hope for a divine deliverer – the Messiah.

This article provides a deep, chronological, and thematic analysis structured for maximum search engine exposure, detailing the critical stages of Christianity’s birth, from the ministry of Jesus to the establishment of the Apostolic Church.

2. The Foundation: The Life and Ministry of Yeshua (Jesus)

 

The undisputed starting point of Christianity is the figure of Jesus of Nazareth (Yeshua in Hebrew), a Jewish itinerant preacher.

A. Historical Context: Roman Judea

 

The 1st century CE was a period of intense religious expectation and political unrest in Judea. Jewish society was divided among sects like the Sadducees, Pharisees, Essenes, and Zealots, all reacting differently to Roman rule. The core hope shared by most was the imminent arrival of the Messiah (Christos in Greek), who was expected to be a political and military king who would restore the Davidic kingdom and expel the Roman occupiers.

B. The Ministry and Teachings of Jesus

 

Jesus’s ministry, lasting approximately three years (c. 30–33 CE), was focused on proclaiming the “Kingdom of God” (or the Kingdom of Heaven). His teachings emphasized:

• Ethical Radicalism: A radical interiorization of the Torah and Mosaic Law (e.g., Sermon on the Mount), focusing on love for God and neighbor, and internal righteousness over external adherence.

• Self-Designation: While Jesus did not openly use the title “Messiah” to avoid political misunderstanding, he referred to himself as the “Son of Man” (a figure from the Book of Daniel) and enacted actions (like healing and forgiving sins) that implied divine or messianic authority.

• Miracles and Signs: His ministry was accompanied by numerous acts of healing and exorcisms, viewed by his followers as confirmation of his divine commission.

C. The Crucifixion and the Messianic Crisis

 

The ultimate crisis that either ended or propelled the movement was the Crucifixion (c. 33 CE). The Roman governor Pontius Pilate executed Jesus under the charge of Sedition (King of the Jews). This execution was devastating to his followers, as a crucified Messiah contradicted the core Jewish expectation of a victorious King. The movement should have died here.

3. The Catalyst: Resurrection and Pentecost

 

The survival and subsequent expansion of the movement hinged entirely on two events that occurred immediately after the Crucifixion:

A. The Resurrection

 

According to the Gospels and the writings of Paul (1 Corinthians 15), the disciples’ despair turned into unwavering conviction based on their alleged experiences of Jesus being bodily resurrected from the dead. This confirmed for them that Jesus was not only the Messiah but also the Son of God who had conquered death. This theological conclusion fundamentally shifted the meaning of the Messiah from a political deliverer to a spiritual redeemer.

B. The Day of Pentecost

 

The event of Pentecost (Shavuot), described in the Book of Acts (Chapter 2), is often referred to as the “birth of the Church.” The disciples gathered in Jerusalem reportedly experienced the descent of the Holy Spirit (Ruach HaKodesh), enabling them to preach the message of Jesus to diverse crowds in their native languages.

• Immediate Effect: Thousands of Jews and Jewish converts were baptized into the movement.

• Identity: This first community, based entirely in Jerusalem, was a Jewish sect that saw itself as the faithful remnant of Israel, holding the unique belief that the Messiah had already arrived.

4. The Apostolic Church (c. 33 – 50 CE): A Sect within Judaism

 

In its earliest decades, the Christian movement was indistinguishable from other Jewish groups.

A. Practice and Identity

 

• Adherence to the Torah: The early believers, led by apostles like Peter and James (the brother of Jesus, the first leader of the church), continued to attend Temple services, observe the Sabbath, keep Kosher (Kashrut), and follow all aspects of Jewish Law.

• The Way: They called themselves followers of “The Way” (HaDerekh), distinguishing themselves not by a new religion, but by their belief that the Messianic Age had been inaugurated by Jesus.

• Communal Life: They shared resources, devoted themselves to prayer and teaching, and practiced baptism as an initiation rite.

B. The First Conflict: Hellenists vs. Hebrews

 

The first internal strain occurred between the local, Aramaic-speaking Jewish believers (Hebrews) and the Greek-speaking Jews (Hellenists) returning from the diaspora. This led to the selection of the first seven deacons (Acts 6), including Stephen, whose radical preaching against the Temple led to his martyrdom. This persecution forced many Hellenistic believers to flee Jerusalem, becoming the first missionaries to places like Samaria, Phoenicia, and Antioch.

5. The Expansion: Paul and the Gentile Question (c. 45 – 60 CE)

 

The movement’s defining transformation—from Jewish sect to global religion—was spearheaded by one man: Saul of Tarsus, later known as the Apostle Paul.

A. The Call of Paul

 

Paul, a highly educated Pharisee who initially persecuted the early believers, experienced a dramatic conversion (Acts 9). His unique mission became the evangelization of the Gentiles (non-Jews).

B. The Circumcision Controversy and the Council of Jerusalem (c. 49 CE)

 

Paul’s success among the Gentiles created the greatest doctrinal crisis of the early church: Did a Gentile have to become a Jew first (via circumcision and adherence to the Mosaic Law) to become a follower of Jesus (the Jewish Messiah)?

• Paul’s Position (Salvation by Grace): Paul fiercely argued (in Galatians and Romans) that salvation was achieved solely by grace through faith in Christ (Sola Fide), and not through adherence to the Law. To demand circumcision was to deny the sufficiency of Christ’s sacrifice.

• The Decision: The Council of Jerusalem (Acts 15), attended by Peter, James, and Paul, ruled in favor of Paul’s position. Gentiles were accepted into the faith without being required to be circumcised, though they were instructed to adhere to basic moral prohibitions (e.g., avoiding idolatry and sexual immorality).

Significance: This decision was the greatest structural separation from normative Judaism. It established Christianity as a universal movement open to all, independent of Jewish ethnicity or Law.

6. The Defining Separation: Rome, The Temple, and Theological Consolidation

 

The final irreversible break with Judaism occurred due to external and internal forces between 60 CE and 100 CE.

A. The Destruction of the Temple (70 CE)

 

The Roman siege and subsequent destruction of the Second Temple in Jerusalem by General Titus was catastrophic for Judaism. It ended the sacrificial system and forced a complete reorganization of Jewish life (leading to Rabbinic Judaism).

• Impact on Christians: The Jewish Christians (Nazarenes) fled Jerusalem (traditionally to Pella). Since their theology was centered on Christ’s sacrifice—which fulfilled the need for the Temple sacrifices—the destruction did not cripple their faith. This physical separation and theological independence marked a final divergence between the two groups.

B. The Canonical Writings

 

The period between 60 and 100 CE saw the writing and collection of the majority of the New Testament books (Gospels, Acts, Epistles, Revelation).

• Theological Consolidation: These writings provided a stable, authoritative framework for the nascent faith, centering on Christology (Jesus as Divine Son) and Soteriology (Salvation by Grace).

• Institutionalization: The emergence of bishops (Episkopoi), elders (Presbyteroi), and deacons (Diakonoi) provided organizational structure beyond the synagogue model.

7. Conclusion: The Emergence of a New Religion

 

By the end of the 1st century, the movement born from Jesus’s Jewish ministry had transitioned into what historians call “Early Christianity.”

It was no longer just a Jewish sect, but a distinct religion identifiable by:

1. Unique Scripture: The New Testament, alongside the Jewish Scriptures.

2. Universal Mission: A commitment to evangelizing all nations (the Great Commission).

3. Distinct Theology: Salvation defined by faith in Christ’s atoning death, independent of the Mosaic Law.

4. Distinct Practice: Weekly gathering on Sunday (The Lord’s Day) instead of the Jewish Sabbath.

Christianity was officially born out of Judaism, through the crucible of a messianic claim, persecution, resurrection belief, and the radical universalism championed by Paul.
