Hi, Brian. Am I missing something in your description of Jesus' trial. Here's my thoughts.
Thirdly, are the contradictions and historical impossibilies in the accounts, the narratives have 'fiction' written all over them. for example, why was Jesus tried without witnesses, by Jewish law you were entitled to two witnesses?
I understood that there were many witnesses, and they contradicted themselves. I found Matthew 26:60-62 real quick, which said that, then said they finally got two to agree that Jesus had said he could destroy the temple and raise it up in three days.
Also, you couldnt be tried on your own testimony. The sanhedrin could only meet in the Temple and they meet could not meet at night. It was also Holy Week, another time that the Sanhedrin couldnt meet.
If Jesus was the problem that the Gospels said he was, then why would these rules stop powerful leaders from taking care of the problem? Maybe they couldn't meet during the holy week, but the holy week was also important enough to urge them to action of it was being thoroughly disrupted. And it seems to me that hundreds of people paving the streets with palm branches and declaring Jesus Messiah is a pretty serious disruption requiring pretty serious action.
I don't think rules about when not to meet would stop the Sanhedrin or any other leaders from taking care of such a problem.
The list goes on and on, why is there no record of the 'tradition' of the Romans releasing a prisoner at Passover?
This seems to carry more weight. I've always wondered, though, why anyone would make up something like that. It seems awful unlikely to me that the whole story is made up; i.e., that Jesus is a completely fictional character, so why add something like the Barabbas story? What's to be gained? Surely calling for Jesus' crucifixion would have sufficiently shown that the Jews rejected him, if that was the purpose. Adding Barabbas hardly makes them to have rejected him more.
For example, Luke mentions the Barabbas story, but in Acts, on the day of Pentecost, he doesn't have Peter bringing up Barabbas at all. He just accuses the crowd of crucifying Jesus (Acts 2:23), without having to bring up Barabbas.
So, I understand it's strange we have no record of releasing a prisoner at Passover, but why would someone make that up? Isn't it just as likely that it was done only a few years, that it happened in a small, relatively insignificant land, and no one mentioned it? Do the writings of the Jews discuss crucifixion and prisoners under Roman rule so much that it should be discussed in their writings even if it only happened a few years?
