Jesus (c. 4 BC – AD 30 or 33), also referred to as Jesus Christ or Jesus of Nazareth (among other names and titles), was a first-century Jewish preacher and religious leader; he is the central figure of Christianity, the world's largest religion. Most Christians believe he is the incarnation of God the Son and the awaited Messiah (the Christ) prophesied in the Hebrew Bible. Virtually all modern scholars of antiquity agree that Jesus existed historically. Research into the historical Jesus has yielded some uncertainty on the historical reliability of the Gospels and on how closely the Jesus portrayed in the New Testament reflects the historical Jesus, as the only detailed records of Jesus' life are contained in the Gospels. Jesus was a Galilean Jew who was circumcised, was baptized by John the Baptist, began his own ministry, and was often referred to as "rabbi". Jesus debated with fellow Jews on how to best follow God, engaged in healings, taught in parables, and gathered followers. He was arrested and tried by the Jewish authorities, turned over to the Roman government, and crucified on the order of Pontius Pilate, the Roman prefect of Jerusalem. After his death, his followers believed he rose from the dead, and the community they formed eventually became the early Christian Church. Accounts of his teachings and life were initially conserved by oral transmission, which was the source of the written Gospels. Christian theology includes the beliefs that Jesus was conceived by the Holy Spirit, was born of a virgin named Mary, performed miracles, founded the Christian Church, died by crucifixion as a sacrifice to achieve atonement for sin, rose from the dead, and ascended into Heaven, from where he will return. Commonly, Christians believe Jesus enables people to be reconciled to God. The Nicene Creed asserts that Jesus will judge the living and the dead, either before or after their bodily resurrection, an event tied to the Second Coming of Jesus in Christian eschatology. The great majority of Christians worship Jesus as the incarnation of God the Son, the second of three persons of the Trinity; there is a small minority of Christian denominations that reject trinitarianism, wholly or partly, as non-scriptural. The birth of Jesus is celebrated annually on 25 December as Christmas. His crucifixion is honored on Good Friday and his resurrection on Easter Sunday. The world's most widely used calendar era—in which the current year is AD 2023 (or 2023 CE)—is based on the approximate birthdate of Jesus. Jesus is also revered in Baha'i faith, Druze faith, Islam and Manichaeism. In Islam, Jesus (often referred to by his Quranic name ʿĪsā) is considered the penultimate prophet of God and the messiah, who will return before the Day of Judgement. Muslims believe Jesus was born of the virgin Mary but was neither God nor a son of God. Most Muslims do not believe that he was killed or crucified but that God raised him into Heaven while he was still alive. In contrast, Judaism rejects the belief that Jesus was the awaited messiah, arguing that he did not fulfill messianic prophecies, and was neither divine nor resurrected.
