Information:  - The quest for the historical Jesus refers to academic efforts to provide a historical portrait of Jesus. Since the 18th century, three scholarly quests for the historical Jesus have taken place, each with distinct characteristics and based on different research criteria, which were often developed during each specific phase. These quests are distinguished from earlier approaches because they rely on the historical method to study biblical narratives. While textual analysis of biblical sources had taken place for centuries, these quests introduced new methods and specific techniques to establish the historical validity of their conclusions.  - The term "historical Jesus" refers to attempts to "reconstruct the life and teachings of Jesus of Nazareth by critical historical methods," in "contrast to Christological definitions ('the dogmatic Christ') and other Christian accounts of Jesus ('the Christ of faith')." It also considers the historical and cultural context in which Jesus lived.  - Jesus (; c. 4 BC  c. AD 30/33), also referred to as Jesus of Nazareth or Jesus Christ, was a Jewish preacher and religious leader who became the central figure of Christianity. Christians believe him to be the Son of God and the awaited Messiah (Christ) prophesied in the Old Testament. Virtually all modern scholars of antiquity agree that Jesus existed historically, although the quest for the historical Jesus has produced little agreement on the historical reliability of the Gospels and on how closely the biblical Jesus reflects the historical Jesus. Jesus was a Galilean Jew who was baptized by John the Baptist and subsequently began his own ministry, preaching his message orally and often being referred to as "rabbi". He was arrested and tried by the Jewish authorities, and was crucified by the order of Pontius Pilate, the Roman prefect. Jesus debated fellow Jews on how to best follow God, performed healings, taught in parables and gathered followers. After his death, his followers believed he rose from the dead, and the community they formed eventually became the Christian Church.  - The historical reliability of the Gospels refers to the reliability and historic character of the four New Testament gospels as historical documents. Some believe that all four canonical gospels meet the five criteria for historical reliability; some say that little in the gospels is considered to be historically reliable. Almost all scholars of antiquity agree that Jesus existed, but scholars differ on the historicity of specific episodes described in the Biblical accounts of Jesus, and the only two events subject to "almost universal assent" are that Jesus was baptized by John the Baptist and was crucified by the order of the Roman Prefect Pontius Pilate. Elements whose historical authenticity is disputed include the two accounts of the Nativity of Jesus, the miraculous events including the resurrection, and certain details about the crucifixion.  - John the Evangelist is the name traditionally given to the author of the Gospel of John. Christians have traditionally identified him with John the Apostle, John of Patmos, and John the Presbyter, though this has been disputed by modern scholars.  - The Gospel According to John (also called the Gospel of John, the Fourth Gospel, or simply John) is one of the four canonical gospels in the New Testament. It traditionally appears fourth, after the synoptic gospels of Matthew, Mark, and Luke. John begins with the witness and affirmation of John the Baptist and concludes with the death, burial, resurrection, and post-resurrection appearances of Jesus.  - The New Testament (Koine Greek:   , "H Kain Diathk") is the second major part of the Christian biblical canon, the first part being the Old Testament, based on the Hebrew Bible. The New Testament discusses the teachings and person of Jesus, as well as events in first-century Christianity. Christians regard both the Old and New Testaments together as sacred scripture. The New Testament (in whole or in part) has frequently accompanied the spread of Christianity around the world. It reflects and serves as a source for Christian theology and morality. Both extended readings and phrases directly from the New Testament are also incorporated (along with readings from the Old Testament) into the various Christian liturgies. The New Testament has influenced religious, philosophical, and political movements in Christendom and left an indelible mark on literature, art, and music.  - John the Apostle ( Aramaic :    Yohanan Shliha ; Hebrew :     Yohanan Ben Zavdai ; Koine Greek :  ; Latin : Ioannes ; c. AD 6 -- c. 106 ) was one of the Twelve Apostles of Jesus according to the New Testament . He was the son of Zebedee and Salome . His brother was James , who was another of the Twelve Apostles . Christian tradition holds that he outlived the remaining apostles and that he was the only one not to die a martyr 's death ( excluding Judas Iscariot who died by suicide ) . The Church Fathers considered him the same person as John the Evangelist , John of Patmos , and the Beloved Disciple , although modern theologians and scholars have not formed a consensus on the relative identities of these mean . The tradition of some Christian denominations holds that John the Apostle is the author of several books of the New Testament .  - John the Baptist ("Ioánnes (h)o baptistés" or   , "Ioánnes (h)o baptízon", known as the prophet "Yahya" in the Quran), also known as John the Baptizer, was a Jewish itinerant preacher in the early first century AD. John is revered as a major religious figure in Christianity, Islam, the Bahá'í Faith, and Mandaeism. He is called a prophet by all of these traditions, and is honoured as a saint in many Christian traditions.
