Christianity in the 1st century covers the formative history of Christianity from the start of the ministry of Jesus (–29 AD) to the death of the last of the Twelve Apostles () and is thus also known as the Apostolic Age. Early Christianity developed out of the eschatological ministry of Jesus. Subsequent to Jesus' death, his earliest followers formed an apocalyptic messianic Jewish sect during the late Second Temple period of the 1st century. Initially believing that Jesus' resurrection was the start of the end time, their beliefs soon changed in the expected Second Coming of Jesus and the start of God's Kingdom at a later point in time.

Paul the Apostle, a Pharisee Jew who had persecuted the early Jewish Christians, converted –36 and started to proselytize among the Gentiles. According to Paul, Gentile converts could be allowed exemption from Jewish commandments, arguing that all are justified by their faith in Jesus. This was part of a gradual split between early Christianity and Judaism, as Christianity became a distinct religion including predominantly Gentile adherence.

Christianity in the 1st century

Jerusalem had an early Christian community, which was led by James the Just, Peter, and John. According to Acts 11:26, Antioch was where the followers were first called Christians. Peter was later martyred in Rome, the capital of the Roman Empire. The apostles went on to spread the message of the Gospel around the classical world and founded apostolic sees around the early centers of Christianity. The last apostle to die was John in .

Etymology

Early Jewish Christians referred to themselves as "The Way" (), probably coming from Isaiah 40:3, "prepare the way of the ". Other Jews also called them "the Nazarenes". According to Acts 11:26, the term Christian (), meaning "follower of Christ", was first used in reference to Jesus's disciples in the city of Antioch. The earliest recorded use of the term "Christianity" () was by Ignatius of Antioch, in around 100 AD.

Origins

Jewish–Hellenistic background

The earliest Christians were an apocalyptic sect within Second Temple Judaism. Christianity "emerged as a sect of Judaism in Roman Palestine" in the Hellenistic world of the first century AD, which was dominated by Roman law and Greek culture. A major challenge for Jews during this time was how to respond to Hellenization and remain faithful to their religious traditions. During the early 1st century AD, there were many competing Jewish sects in the Holy Land, including Pharisees, Sadducees, Essenes, and other groups. Each group adopted different stances toward Hellenization.

The basic tenets of Jewish religion were ethical monotheism, the Torah (or Law), and an eschatology that looked forward to a future messianic age. Jews believed the Law was given by God to guide them in their worship of the Lord and in their interactions with each other. A central concern in 1st century Judaism was the covenant with God, and the status of the Jews as the chosen people of God. Many Jews believed that this covenant would be renewed with the coming of the messiah.

Messiah (Hebrew: ) means "anointed" and is used in the Bible to designate Jewish kings and in some cases priests and prophets whose status was symbolized by being anointed with holy anointing oil. It can refer to people chosen by God for a specific task, such as the whole Israelite nation (1 Chronicles 16:22; Psalm 105:15) or Cyrus the Great who ended the Babylonian captivity (Isaiah 45:1).The term is most associated with King David, to whom God promised an eternal kingdom (2 Samuel 7:11–17). After the destruction of David's kingdom and lineage, this promise was reaffirmed by the prophets Isaiah, Jeremiah, and Ezekiel, who foresaw a future Davidic king who would establish and reign over an idealized kingdom.

In the Second Temple period, there was no consensus on who the messiah would be or what he would do. Most commonly, he was imagined to be an Endtimes son of David going about the business of "executing judgment, defeating the enemies of God, reigning over a restored Israel, establishing unending peace". The messiah was often referred to as "King Messiah" () or malka meshiḥa in Aramaic. Yet, there were other kinds of messianic figures proposed as well—the perfect priest or the celestial Son of Man who brings about the resurrection of the dead and the final judgment. The concept has its root in the apocalyptic literature of the 2nd century BC to 1st century BC.
