One of the themes of Luke’s account of the Passion is that he portrays the Crucifixion as the royal enthronement of Jesus. To be clear, it is an unexpected enthronement: he is being put to death, after all. But, as we read through the Passion account, pay attention to all the ways Jesus is being prepared for a “coronation.”
For example,
Then Herod and his soldiers ridiculed and mocked him. Dressing him in an elegant robe, they sent him back to Pilate.
Luke 23:11
Jesus is a prisoner about to be crucified, but Luke wants us to pick up on the irony: Herod thinks he is mocking him, but he is really preparing him for his enthronement.
