5.5.14.
The interpretation of Jesus’ death as a betrayal: Judas. Josephus calls the Christians sons of Judas the Galilean,

because he brackets all Christians together as supporters of the insurrection. The opposite is true in the Christian sources: the relationship between Christians and Judas is not denied, but Jesus is the patron and the rebels are only pupils, and unworthy ones at that, since they gave Jesus’ enemies and excuse to kill him.
Nor do the Gospels hide the rebels’ opinion: in the scene of Peter’s denial (Mark 14:66ff par.) Peter is identified as a participant in Judas the Galilean’s rebellion due to his Galilean dialect: he is accused of betraying Jesus’ cause, which is identified with the rebels’ cause.
The crucifixions of James and Peter show that the Palestinian Jesus movements were by no means always non-violent and that they did not refuse all collaboration with the rebels. That only changed after the end of the Jewish Revolt in 70 AD.
