Joseph,
I think that it is obvious that you have no scholarly studies to support your theory. When asked to show it, you try to shift the burden of proof and say that all you are doing is tying similar stories together, so the later ones must be fake. If you are going to raise the theory that Mark made up the stories, you must show that he did. You must not ignore the evidence that he was an eyewitness, you must not ignore the evidence that he was killed for his "made up stories", and you must not ignore the portions of the Gospels where he says what he is writing is true. You must be the one to say that he is lying. That would be your role as a skeptic. I think you will start ignoring me because you cannot so this when asked.
What you have done is pick some stories from the old testament, find apparant similarites and than say that that means the new testament story is made up. As I have pointed out, that is not a logical conclusion and is not a rational leap from the evidence you have presented.
Can you present one biblical scholar who has made the same connections you have between these stories? They of course would think both are true, but if they are connected surely a Biblical scholar in the past would have made the connection.
As for the David stories, you are too general to make the connection so I am unable to respond. There are alot of people in the Bible that lamented and experienced agony such as Jesus in the garden. Which event to you think that was copied from?
As for the stories of the feedings we have discussed that in earlier posts. That is why I did not repeat that here. But if you will recall, the stories are not as similar as you have suggested and have no connection to each other.
There are of course some striking differences between Jonah and the Jesus story which you are ignoring:
1. Jonah was asked to go to a particular city and he went the opposite direction. Jesus was going no where in particular.
2. Jonah was not following God's instructions, he was running away from them. Jesus was dooing what he was sent here for.
3. Jonah was on a bost full of people who did not believe in God. Jesus was on a boat with his followers.
4. Jonah was in a deep sleep in the bottom of the boat. Jesus was napping in the stern, there is no mention that he was in a deep sleep.
5. The men on Jonah's boat did not look to Jonah to save them, but that he was the cause of the storm. The men on Jesus' boat looked to him to save them.
6. Jonah was thrown overboard. Jesus was not thrown overboard.
7. Jonah was eaten by a big fish and stayed in his belly praying to God for three days. Jesus was not eaten by a fish and simply told the storm to quiet.
8. Jonah had to repent for not following God's instuctions. Jesus had nothing to repent for.
9. The storm in Jonah was apparently sent by God because of Jonah's failure to follow his wishes. The storm in Jesus' version was apparently naturally caused for no particular reason.
10. The moral of the stories and the idea they are trying to teach are completely different. Jonah teaches that God will sometimes ask you to do things that are in his plan, but not in yours, but you must trust him. The purpose behind the story in Mark is to show that Jesus had control over nature.
Now, you have pointed out five apparent similarites, I have pointed out ten differences. Do you still think Mark copied Jonah for this episode?
It is clear in Jonah, that God spared the Nievites because they repented. It was an example of God's grace.
Finally, what makes you think that the Bible readers needed to be told that only God could make a man live in a fish for three days? Why would they need to be told that that miracle was from God? Don't you think that is obvious?
