Judas Iscariot
There are several explanations as to why Judas betrayed Jesus. In the earliest account, in the Gospel of Mark, when he goes to the chief priests to betray Jesus, he is offered money as a reward, but it is not clear that money is his motivation. In the Gospel of Matthew account, on the other hand, he asks what they will pay him for handing Jesus over. In the Gospel of Luke and the Gospel of John, the devil enters into Judas, causing him to offer to betray Jesus. The Gospel of John account has Judas complaining that money has been spent on expensive perfumes to anoint Jesus which could have been spent on the poor, but adds that he was the keeper of the apostles' purse and used to steal from it.
Against the Galileans
Julian spends time discussing how, even after having nominally embraced Jewish traditions, Galileans have really rejected them and only accepted their blasphemy of the gods (238A–B). He criticizes the belief that Jesus is the prophet that was predicted by Moses and Isaiah, as Jesus, supposedly being the son of God, was not descended from Judah, and says that the idea of a god who claims to be the sole God creating a being equal to him (and thus a second God) goes against the monotheistic beliefs of Judaism (253A–B). He points out that Galileans have abandoned many of the central tenets of Judaism, such as the sacrificing of animals (305D) and its dietary restrictions (314C), and criticizes the claim that God has set up a new law for them while Moses so adamantly warned against changing the law (320B).
