I did a quick-and-dirty review and got this list, though I probably missed a detail or three.
- This is about Jesus
- John says someone more important is coming
- John baptizes Jesus (implicit in John's)
- The Spirit descends like a dove on Jesus
- Some of the apostles are named
- Jesus cleanses the temple (non-linear narrative in John's?)
- 5000 are fed from a small lunch
- Jesus walks on water
- Jesus heals people (not the same list in each)
- Jesus teaches (not quite the same material quoted in each)
- Jesus says he's going to die
- Leaders plot against him
- Jesus and his disciples have a meal together with last instructions
- Peter boasts of loyalty, but then denies Jesus
- Judas betrays Jesus
- Jesus is tried before a Jewish assembly
- Jesus is tried before Pilate
- Pilate doesn't want to kill him
- Barabbas is released instead by popular acclaim
- Jesus is crucified along with a couple of criminals
- Women are present (Mary of Magdala, another Mary, others(*))
- Jesus quotes scripture on the cross
- Jesus dies
- Joseph of Arimathea takes custody of the body and buries it in his own tomb
- There is a stone in front of the tomb
- On Sunday the women (Mary of Magdala and others) find the empty tomb
- Jesus appears alive to the disciples
If overlap is there for emphasis, then what is emphasized?
1,2,3,4 testify that Jesus is going to be the one from God. 6 say he cleanses worship; 7,8,9 say he can control the world; 10 shows that he wants to teach us, 11 says he knows what’s about to happen.
The rest of the later ones are the outline of the plot to destroy him and its unexpected result.
The Jewish leaders plot against him and try him in their own court (his own people). The Roman leader can't be bothered to administer justice (their claim to fame). A criminal goes free (like us).
Jesus is crucified. (This is a curse for both Jews and Romans.)
Judas is a traitor (like plenty of others ever since). Peter is a failure (the only good argument I know for assigning him a "first among equals" position).
Women are essential witnesses (seriously counter cultural).
A rich man you never heard of before (or afterwards) takes the risk of burying Jesus--and in his own tomb at that.
After the Sabbath the tomb is empty, and Jesus shows himself alive.
For full instruction you want the union of the gospels, but I think I like the intersection too. Some things to meditate on.
(*) When I was little I was terribly confused by all the different Marys, Herods, and Johns. It still doesn't help that "Mary the mother of Joses" / "Mary the mother of James and Joseph" and Mary the mother of Jesus may or may not be the same person.
