John does not describe the transfiguration, as the other Gospels do; in a sense, John’s whole story is about the transfiguration. He invites us to be still and know; to look again into the human face of Jesus of Nazareth, until the awesome knowledge comes over us, wave upon terrifying wave, that we are looking into the human face of the living God. And he leads us on, with our awe and bewilderment reaching its height, to the point where we realize that the face is most recognizable when it wears the crown of thorns. When John says, “We beheld his glory,” he is thinking supremely of the cross. And those who see this glory in this cross are, very shortly afterwards, commissioned to follow the one who has made this glory visible. — N. T.
