This was a tricky play to devise, because the Gospel passage reports, in rapid fire fashion, three major events already narrated in much greater detail in other Gospel passages (and already covered in three other plays): the baptism of Jesus, the temptation of Jesus, and the arrest of John the Baptist. Then I noticed that when I wrote the play about the temptation of Jesus, I never actually said what the three temptations were. (Instead, I showed various members of the group being tempted in different ways.) I also realized that there was no Gospel account of Judas actually joining the disciples. So then my way was clear: I would write a play about Judas finally joining the group, and include within it an account of the three temptations of Jesus.
I think that combination turned out well. The encounter between Jesus and Judas is itself a kind of testing: each of them is trying to evaluate the other. And Judas’ reactions, especially to the third temptation, foreshadow the temptation he’ll face later in his story. Finally, I also got a chance to do more questioning of the handling of many OT passages in the Gospels!
