The hymn asks the right question: What do you want us to see there that your close companions saw? Through the eye-witness accounts of Peter, James, and John, we get to take in this heavenly vision before the deepest darkness of Jesus’ passion, his suffering, and his death. But what are we to see there? What are we to take away? When Jesus was baptized, God spoke there, but that time he spoke for the sake of Jesus. He told him, “You are my Son…” (Mk 1:11). Here, Jesus is glorified, and the Father speaks once again, but, this time, for the sake of the disciples. He speaks to them (and through them to us): “This is my Son…Listen to him.” Today, once again, we become witnesses of his glory. Mark 9:2-9
