How did the myth of Jesus' resurrection originate?

On this question of the timing of the crucifixion, I think there is little doubt that the Synoptics represent Jesus' last meal with his disciples as a Passover Seder. I recall from seminary that the German scholar Joachim Jeremias did an exhaustive study of the matter in a book entitled The Eucharistic Words of Jesus.

After 30 years I can't recall all the details, but I think it was said that there are four cups of wine during the Seder and Jeremias' analysis showed that Jesus used the third cup for the institution of communion.

That of course would mean that John was wrong about the crucifixion occurring on the Day of Preparation.

Here is a link to a study which summarizes much of the argument. I don't have time to read it in detail right now.

Anyway from the following passages it seems clear that the Synoptics placed the last supper on the very day of Passover.

On the first day of the Festival of Unleavened Bread, the day the lambs for the Passover meal were killed, Jesus' disciples asked him, “Where do you want us to go and get the Passover meal ready for you?” (Mark 14:12)

The day came during the Festival of Unleavened Bread when the lambs for the Passover meal were to be killed. Jesus sent Peter and John with these instructions: “Go and get the Passover meal ready for us to eat.” (Luke 22:7-8)

I don't think it could be much plainer that this is the Day of Preparation when, according to John, the crucifixion took place.
