Ministry of Jesus in the context of "Mennonites"

Jewish Christians were the followers of a Jewish religious sect that emerged in Roman Judea during the late Second Temple period, under the Herodian tetrarchy (1st century AD). These Jews believed that Jesus was the prophesied Messiah and they continued their adherence to Jewish law. Jewish Christianity is the historical foundation of Early Christianity, which later developed into Nicene Christianity (which comprises the Roman Catholic, Eastern Orthodox, Oriental Orthodox, and Protestant traditions) and other Christian denominations.

Christianity started with Jewish eschatological expectations, and it developed into the worship of Jesus as the result of his earthly ministry in Galilee and Jerusalem, his crucifixion, and the post-resurrection experiences of his followers. Jewish Christians drifted apart from Second Temple Judaism, and their form of Judaism eventually became a minority strand within mainstream Judaism, as it had almost disappeared by the 5th century AD. Jewish–Christian gospels are lost except for fragments, so there is a considerable amount of uncertainty about the scriptures which were used by this group of Christians.

Christianity is an Abrahamic monotheistic religion, which states that Jesus is the Son of God and rose from the dead after his crucifixion, whose coming as the messiah (Christ) was prophesied in the Old Testament and chronicled in the New Testament. It is the world's largest and most widespread religion with over 2.3 billion followers, comprising around 28.8% of the world population. Its adherents, known as Christians, are estimated to make up a majority of the population in 120 countries and territories.

Christianity remains culturally diverse in its Western and Eastern branches, and doctrinally diverse concerning justification and the nature of salvation, ecclesiology, ordination, and Christology. Most Christian denominations, however, generally hold in common the belief that Jesus is God the Son—the Logos incarnated—who ministered, suffered, and died on a cross, but rose from the dead for the salvation of humankind; this message is called the gospel, meaning the "good news". The four canonical gospels of Matthew, Mark, Luke and John describe Jesus' life and teachings as preserved in the early Christian tradition, with the Old Testament as the gospels' respected background.

In Christian theology and ecclesiology, the apostles, particularly the Twelve Apostles (also known as the Twelve Disciples or simply the Twelve), were the primary disciples of Jesus according to the New Testament. During the life and ministry of Jesus in the 1st century AD, the apostles were his closest followers and became the primary teachers of the gospel message of Jesus. There is also an Eastern Christian tradition derived from the Gospel of Luke that there were seventy apostles during the time of Jesus' ministry.

The commissioning of the Twelve Apostles during the ministry of Jesus is described in the Synoptic Gospels. After his resurrection, Jesus sent eleven of them (as Judas Iscariot by then had died) by the Great Commission to spread his teachings to all nations.

Jesus (c. 6 to 4 BC – AD 30 or 33), also referred to as Jesus Christ, Jesus of Nazareth, and many other names and titles, was a 1st-century Jewish preacher and religious leader in the Roman province of Judaea. He is the central figure of Christianity, the world's largest religion. Most Christians consider Jesus to be the incarnation of God the Son and awaited messiah, or Christ, a descendant from the Davidic line that is prophesied in the Old Testament. Virtually all modern scholars of antiquity agree that Jesus existed historically. Accounts of Jesus's life are contained in the Gospels, especially the four canonical Gospels in the New Testament. Since the Enlightenment, academic research has yielded various views on the historical reliability of the Gospels and how closely they reflect the historical Jesus.

According to Christian tradition, as preserved in the Gospels and the Acts of the Apostles, Jesus was circumcised at eight days old, was baptized by John the Baptist as a young adult, and after 40 days and nights of fasting in the wilderness, began his own ministry. He was an itinerant teacher who interpreted the law of God with divine authority and was often referred to as "rabbi". Jesus often debated with his fellow Jews on how to best follow God, engaged in healings, taught in parables, and gathered followers, among whom 12 were appointed as his apostles. He was arrested in Jerusalem and tried by the Jewish authorities, handed over to the Roman government, and crucified on the order of Pontius Pilate, the Roman prefect of Judaea. After his death, his followers became convinced that he rose from the dead, and following his ascension, the community they formed eventually became the early Christian Church that expanded as a worldwide movement.

Christianity in the 1st century covers the formative history of Christianity from the start of the ministry of Jesus (c. 27–29 AD) to the death of the last of the Twelve Apostles (c. 100) 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 Christians of the Roman Province of Judea, converted c. 33–36 and began 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.

Paul, also named Saul of Tarsus, commonly known as Paul the Apostle or Saint Paul, was a Christian apostle (c. 5 – c. 64/65 AD) who spread the teachings of Jesus in the first-century AD. For his contributions towards the New Testament, he is generally regarded as one of the most important figures of the Apostolic Age, and he also founded several Christian communities in Asia Minor and Europe from the mid-40s to the mid-50s AD.

The main sources of information on Paul's life and works are Paul's letters and the Acts of the Apostles in the New Testament. Approximately half of its content documents his travels, preaching, and miracles. Paul was not one of the Twelve Apostles, and he did not know Jesus during his lifetime. Nonetheless, Paul was a contemporary of Jesus and personally knew eyewitnesses of Jesus such as his closest disciples (Peter and John) and brother James since the mid 30s AD, within a few years of the crucifixion (ca. 30–33 AD). He had knowledge of the life of Jesus and his teachings. According to the Acts, Paul lived as a Pharisee and participated in the persecution of early disciples of Jesus before his conversion. On his way to arrest Christians in Damascus, Paul saw a bright light, heard Christ speak, was blinded, and later healed by Ananias. After these events, Paul was baptized, beginning immediately to proclaim that Jesus of Nazareth was the Jewish messiah and the Son of God. He made three missionary journeys to spread the Christian message to non-Jewish communities.

The Gospel of Mark is the second of the four canonical Gospels and one of the three synoptic Gospels. It tells of the ministry of Jesus from his baptism by John the Baptist to his death, the burial of his body, and the discovery of his empty tomb. It portrays Jesus as a teacher, an exorcist, a healer, and a miracle worker. Jesus refers to himself as the Son of Man and is called the Son of God, though he keeps his messianic nature secret; even his disciples fail to understand him. This is in keeping with the Christian interpretation of prophecy, which is believed to foretell the fate of the messiah as a suffering servant.

Traditionally attributed to Mark the Evangelist, the companion of the Apostle Peter, the gospel is anonymous, and scholarship is inconclusive on its authorship. It is dated to around 70 AD and was likely written in Rome for a gentile audience. Mark is classified as an ancient biography and was meant to strengthen the faith of its readers. Most scholars hold that Mark is the earliest gospel and was used by both Matthew and Luke. Mark has therefore often been seen as the most reliable gospel, though this has recently been challenged.

The Gospel of Luke is the third of the New Testament's four canonical Gospels. It tells of the origins, birth, ministry, death, resurrection, and ascension of Jesus. Together with the Acts of the Apostles, it makes up a two-volume work which scholars call Luke–Acts, accounting for 27.5% of the New Testament.

The text is anonymous, not naming its author. Perhaps most scholars think that he was a companion of Paul, but others cite differences between him and the Pauline epistles. In the popular Two-source hypothesis, Luke used the Gospel of Mark and a hypothetical collection called Q, with unique material often called L, though alternative hypotheses that posit the direct use of Matthew by Luke or vice versa without Q are increasing in popularity within scholarship. Luke follows Mark closely compared to other ancient historians’ usage of sources, though the parallels and variations of the Synoptic gospels are typical of ancient historical biographies. Luke tends to follow his sources closely when checked. The most common dating for its composition is around AD 80–90. The earliest witnesses for the Gospel of Luke are the Alexandrian and the revised western text-type.

The Gospel of John is the fourth of the New Testament's four canonical Gospels. It contains a schematic account of the ministry of Jesus, with seven "signs" culminating in the raising of Lazarus (foreshadowing the resurrection of Jesus) and seven "I am" discourses culminating in Thomas's proclamation of the risen Jesus as "my Lord and my God". The penultimate chapter's concluding verse set out its purpose, "that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in his name."

John was written between AD 90–100. The gospel is anonymous, although it identifies a "disciple whom Jesus loved" as the source of its traditions and perhaps author. Twentieth-century scholarship interpreted the gospel within the paradigm of a "Johannine community", but this has been increasingly challenged in the 21st century, and there is currently considerable debate over the gospel's historical context. As it is closely related in style and content to the Johannine epistles, most scholars treat the four books, along with the Book of Revelation, as a single corpus of Johannine literature, albeit not by the same author.
