"In his writings, Josephus mentions the Pharisees, the Sadducees, and the Herodians. He mentions Caiaphas, Pontius Pilate, John the Baptist, Jesus (twice) and James the brother of Jesus. He also mentions the Essenes - the strict religious sect within Judaism that founded the Qumran community, where the Dead Sea Scrolls were found.

Historians think one part that talks about Jesus had been added to. With these extra bits taken away they think Josephus wrote:

"About this time there lived Jesus, a wise man, for he was a performer of wonderful deeds, a teacher of such men as are happy to accept the truth. He won over many of the Jews and many of the Gentiles. When Pilate, at the suggestion of the leading men among us, had condemned him to the cross, those who had loved him at the first did not forsake him; and the tribe of Christians, so named from him, are not extinct to this day."
Antiquities, Book 18, 63-64.

"Convened the Sanhedrin (the highest Jewish religious court / governing body). He had brought before them the brother of Jesus the so-called Christ, who was called James, and some other men, whom he accused of having broken the law, and handed them over to be stoned."
Antiquities, Book 20, 200."
