What does Luke 23:51 mean?
Jesus has died and Joseph of Arimathea wants to bury Him. Joseph is a respected member of the Sanhedrin. Luke describes him as "a good and righteous man" (Luke 23:50). When the council declared Jesus blasphemous and delivered him to Pilate as an enemy of Rome, Joseph didn't agree. He is a disciple of Jesus, but he is still afraid of his fellow Jewish leaders (John 19:38). It's possible he skipped the meeting of the Sanhedrin early that morning (Luke 22:66–71) as well as those before Pilate (Luke 23:1–5) so his devotion to Jesus wouldn't be discovered.Earlier in Luke, Simeon was described as "righteous and devout, waiting for the consolation of Isarel" (Luke 2:25). When he saw the baby Jesus, Simeon immediately knew Him to be God's salvation (Luke 2:27–32). The character quality of "righteous" is related to Simeon's "waiting" and Joseph's "looking for." "The righteous shall live by faith," Paul says (Galatians 3:11; cf. Habakkuk 2:4). Both men wait for God's redemption of Israel.
Joseph has had the added benefit of hearing Jesus talk about how the kingdom of God is near. Even now, when the man he knows is the Christ hangs dead, he has faith. Requesting Jesus' body was bold. In doing so, Joseph identified himself with Jesus, whom the Sanhedrin clearly despised and who had been officially marked as a criminal by Rome, even if Pilate knew His innocence. Such a burial was unusual treatment for a man who had been condemned to the humiliation of crucifixion. But Joseph "[takes] courage" (Mark 15:43) and approaches Pilate (Luke 23:52). With Nicodemus, another covert disciple, he wraps Jesus' body in aromatics and lays Him in his own tomb (John 19:39–42).
