Roman Judea in the context of "Israeli coastal plain"

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.

The region of Palestine is part of the wider region of the Levant, which represents the land bridge between Africa and Eurasia. The areas of the Levant traditionally serve as the "crossroads of Western Asia, the Eastern Mediterranean, and Northeast Africa", and in tectonic terms are located in the "northwest of the Arabian Plate". Palestine itself was among the earliest regions to see human habitation, agricultural communities and civilization. Because of its location, it has historically been seen as a crossroads for religion, culture, commerce, and politics. In the Bronze Age, the Canaanites established city-states influenced by surrounding civilizations, among them Egypt, which ruled the area in the Late Bronze Age. During the Iron Age, two related Israelite kingdoms, Israel and Judah, controlled much of Palestine, while the Philistines occupied its southern coast. The Assyrians conquered the region in the 8th century BCE, then the Babylonians c. 601 BCE, followed by the Persian Achaemenid Empire that conquered the Babylonian Empire in 539 BCE. Alexander the Great conquered the Persian Empire in the late 330s BCE, beginning Hellenization.

In the late 2nd-century BCE Maccabean Revolt, the Jewish Hasmonean Kingdom conquered most of Palestine; the kingdom subsequently became a vassal of Rome, which annexed it in 63 BCE. Roman Judea was troubled by Jewish revolts in 66 CE, so Rome destroyed Jerusalem and the Second Jewish Temple in 70 CE. In the 4th century, as the Roman Empire adopted Christianity, Palestine became a center for the religion, attracting pilgrims, monks and scholars. Following Muslim conquest of the Levant in 636–641, ruling dynasties succeeded each other: the Rashiduns; Umayyads; Abbasids; the semi-independent Tulunids and Ikhshidids; Fatimids; and the Seljuks. In 1099, the First Crusade resulted in Crusaders establishing of the Kingdom of Jerusalem, which was reconquered by the Ayyubid Sultanate in 1187. Following the invasion of the Mongol Empire in the late 1250s, the Egyptian Mamluks reunified Palestine under its control, before the region was conquered by the Ottoman Empire in 1516, being ruled as Ottoman Syria until the 20th century largely without dispute.

The Christ myth theory, also known as the Jesus myth theory, Jesus mythicism, or the Jesus ahistoricity theory, is the fringe view that the story of Jesus is a work of mythology with no historical substance. Alternatively, in terms given by Bart Ehrman paraphrasing Earl Doherty, it is the view that "the historical Jesus did not exist. Or if he did, he had virtually nothing to do with the founding of Christianity."

The mainstream scholarly consensus, developed in the three quests for the historical Jesus, holds that there was a historical Jesus of Nazareth who lived in first-century AD Roman Judea, but his baptism and crucifixion are the only facts of his life about which a broad consensus exists. Beyond that, mainstream scholars have no consensus about the historicity of other major aspects of the gospel stories, nor the extent to which they and the Pauline epistles may have replaced the historical Jesus with a supernatural Christ of faith.
