In the middle of the 2nd century CE, Christian leaders (mostly bishops) later designated as Church Fathers, began writing apologia to Roman Emperors and others in defense of Christianity. As educated men in various schools of philosophy, they utilized philosophical concepts of the universe and terminology to accord Christian views of Jesus with philosophical claims. Thus, the elevation of Jesus of Nazareth from a Jewish wonder-worker to a source of all power in the universe.
Christianity is a monotheistic, deontological, grass-roots, Jewish sectarian movement that focuses upon the life, teachings, and mission of Jesus of Nazareth (also known as Jesus the Christ). It began in Jerusalem in Judea in the 1st century CE, and moved northward and westward in the Mediterranean region through the efforts and activities of Jesus' personally chosen disciples & apostles - Peter, Paul, James, and John (among others). Once a small, Messianic Jewish sect, by the 4th century CE, Christianity dominated all other religions in Greco-Roman society and spread throughout the Roman Empire even as far north as ancient Britain and possibly as far east as India. Unlike other Gnostic movements of the era, the Christian message was meant to be openly and honestly shared to anyone who would hear it - regardless of race, gender, economic, or social status. The narrative of Christianity is complex as are the early Christian doctrines, which are best understood in the cultural and historical contexts of the Christian movement and through the pivotal decisions and actions of its adherents.
Socially, this led to controversy and conflict with the ruling powers in Jerusalem, Judea, and Roman demesnes. Eventually, Jesus was arrested, tried, and convicted by the Sanhedrin under Caiaphas, the Jewish High Priest, and for treason in the Roman courts under Pontius Pilate, the Roman governor of Judea (although Jesus' Jewish enemies wanted him convicted of blasphemy). Ironically, in both instances, the trial of Jesus violated traditional, official Jewish and Roman jurisprudence for capital crimes, procedures, and protocol, ending with an unlawful sentence and subsequent execution by crucifixion, which was carried out by Roman soldiers on what later came to be called, “Good Friday.”
According to multiple eyewitness testimonies in the region (as detailed in the Gospels and the Epistles), through a supernatural resurrection by God, Jesus -miraculously alive and well - appeared to a variety of people, having perfectly performed his father's mission on earth. Somewhat ironic considering the Patriarchy of the era, Jesus' first appearance was to a woman - Mary Magdalene - who immediately ran and told the other Disciples about what she had seen and heard. Later encounters of Jesus included Mary, the mother of James; Salome; Joanna; James, the half-brother of Jesus; the lead Disciple Peter and eventually all of the remaining eleven Disciples (except for Judas who had committed suicide, earlier); and the Apostle Paul (formerly known as Saul of Tarsus) who would be later so instrumental in establishing Christianity in Europe. In fact, in Paul's First Epistle to the Corinthians, he records that over 500 people saw Jesus, the risen Christ, all at the same time, although some of them had already died by the time he wrote his second letter to Corinth (1 Corinthians 15:6, NASB).
After a 40-day period of visitation and confirmation that he had indeed risen from the dead as he said he would, Jesus left the earthly realm and ascended into Heaven, sending the Holy Spirit to guide and empower them, having already prepared and called his disciples to be teachers, guides, and proclaimers of a fulfilled Messianic promise of God's loving plan for salvation that was to be shared from Judea to all the known Gentile (non-Jewish) world.
With the command of Jesus to “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age” (Matthew 28:19–20, NASB), the followers of Jesus began sharing the good news of the resurrected Messiah (the Christ, gr.) - along with Jesus' earlier ethical admonishments of perfect love of God and neighbor.
Although the Pharisees and Jewish leaders considered the dangerous influence of Jesus to be quelled with his execution (especially with the threat/warning of crucifixion for embracing such beliefs), the Christian message continued to be as appealing and inviting as ever, and the movement grew, exponentially. Moreover, whereas oppressive and politically controlling leaders of Judaism continued in their reactionary ways, the early Christians offered inclusivity and freedom to those who wished to join in “The Way” (as the movement was sometimes called).
And all those who had believed were together and had all things in common; and they began selling their property and possessions and were sharing them with all, as anyone might have need. Day by day continuing with one mind in the temple, and breaking bread from house to house, they were taking their meals together with gladness and sincerity of heart, praising God and having favor with all the people. And the Lord was adding to their number day by day those who were being saved (Acts 2:44–47, NASB).
Not surprisingly, as the number of Jesus disciples rose, the Jewish leaders who had earlier been threatened by Jesus' message and influence upon a society which they wanted full hegemony, worried the Jesus movement could reignite, and turned their criticisms and persecutions upon Jesus' disciples and followers, many of whom fled the area to safer, more receptive areas (at least, initially). Still, many early Christian leaders bravely stayed in Jerusalem and Judea to speak their message of Christian love and salvation, leading to public abuse by authorities determined to extinguish this dangerous sect of Messianic Judaism. The Apostle Luke records,
This Christian zeal energized many to follow; however, it energized many on the other side of the argument to more serious efforts. Thus, the Apostle Stephen is the first recorded martyr of the Christian movement (Acts 7, NASB), and based upon extra-biblical accounts of the time, others soon thereafter followed Stephen's demise. The Disciple Andrew was crucified on an 'X' in Greece; the Disciple Matthew was killed by the sword in Ethiopia; the Disciple Bartholomew (also known as Nathanael) was whipped to death in Armenia; the Disciple James Zebedee was beheaded in Jerusalem; the Disciple Thomas was stabbed by a spear in India; the Disciple Jude was killed by arrows during his missionary work; the replacement Disciple, Matthias was stoned and beheaded for his faith; the Apostle John (and Gospel writer) was boiled in oil but somehow survived; the Apostle Barnabas was stoned to death in Salonica; the Gospel writer, John Mark, was dragged to death by horses through the streets of an unnamed Egyptian city; James the Just was thrown over a cliff, somehow survived, but then was immediately clubbed to death; the leader of the Disciples, Peter, was crucified upside down in Rome under the Emperor Nero; and the Apostle Paul was beheaded under the persecutions of Nero.
