The historicity of Jesus Christ is well-established by early Roman, Greek, and Jewish sources, and these extrabiblical writings affirm the major details of the New Testament portrait of the Lord. The first-century Jewish historian Flavius Josephus made specific references to John the Baptist, Jesus Christ, and James in his Antiquities of the Jews. In this work, Josephus gives us many background details about the Herods, the Sadducees and Pharisees, the high priests like Annas and Caiaphas, and the Roman emperors mentioned in the gospels and Acts.
