Historical Development of Christianity in the Roman Empire

Origins of Christianity

  • Christianity emerged as a religion from the fringes of the Roman Empire.

    • Originated as a Jewish sect in Judea and Galilee.

    • Centered on the teachings and early ministry of Jesus.

Early Followers and Evangelism

  • At the time of Jesus's crucifixion (around 30 C.E.), he had at most hundreds of followers.

    • Early followers included his apostles who spread the faith.

    • The faith was spread not only to Jews but also to gentiles (non-Jews).

Persecution of Christians

  • Emperor Nero's reign included significant persecution of Christians.

    • Notably, the Great Fire of Rome in 64 C.E. was used by Nero to justify a purge of Christians.

    • Many historians believe apostles Peter and Paul were killed during these purges.

    • Artwork depicts Nero using Christians as torches to illuminate his gardens.

Impact of the Destruction of the Second Temple

  • The Second Temple in Jerusalem was destroyed in 70 C.E. under Emperor Vespasian.

    • This event had profound significance for both Jews and early Christians.

    • Christianity's center was Jerusalem, and the destruction caused displacement among Jews and early Christians.

    • Christian centers shifted to various locations within the Roman Empire, notably Antioch.

Tensions Between Christians and Roman Society

  • Christians faced discomfort and suspicion due to their growing numbers and refusal to worship Roman gods.

    • Differences from Jewish practices, which tended to be more insular.

    • Christians actively engaged in evangelical missions, leading to family divisions.

Escalating Persecution in Later Centuries

  • Persecutions increased through the second and third centuries as Christians gained prominence.

    • Noteworthy was the extensive purge under Emperor Diocletian, who sought to consolidate power.

    • Dubbed the most extreme state-sponsored persecution of Christians.

The Rise of Constantine

  • Constantine emerged as an emperor following Diocletian.

    • He saw a vision of a Christian cross before the Battle of the Milvian Bridge in 312 C.E.

    • Interpreted the vision as a divine sign to fight under the symbol of the cross.

    • Achieved victory, marking a significant turning point for Christians.

The Edict of Milan

  • The Edict of Milan was established in 313 C.E., officially legalizing Christianity.

    • This marked a substantial change from previous persecutions.

The Council of Nicea

  • In 325 C.E., Constantine convened the Council of Nicea.

    • Gathered bishops from all of Christendom to unify beliefs and doctrines.

    • Development of the Nicene Creed, addressing the nature of Jesus as son of God.

    • The creed established that Jesus and God are one and the same, countering claims of lesser divinity.

    • On his deathbed, Constantine was baptized, becoming the first Christian emperor of the Roman Empire.

Further Developments under Emperor Theodosius

  • By the end of the fourth century, Emperor Theodosius declared Christianity the official religion of the Roman Empire.

    • Marked a significant transformation from a previously anti-Christian stance to full acceptance.

    • Theodosius was the last emperor to rule over both the Eastern and Western Roman Empires.

Summary of Christian Transformation in the Roman Empire

  • Initially, the response of the Roman Empire to Christianity was primarily negative, with little concern for the movements in Judea and Galilee.

  • Over the centuries, perceptions changed, leading to Christianity being established as the official religion of the empire from a state of persecution to endorsement.
