⁴ Exactly what did the three apostles see? The following is Luke’s description of the event: “As [Jesus] was praying the appearance of his face became different and his apparel became glitteringly white. Also, look! two men were conversing with him, who were Moses and Elijah. These appeared with glory and began talking about his departure that he was destined to fulfill at Jerusalem.” Then, “a cloud formed and began to overshadow [the apostles]. As they entered into the cloud, they became fearful. And a voice came out of the cloud, saying: ‘This is my Son, the one that has been chosen. Listen to him.’”—Luke 9:29-31, 34, 35.

 5. What effect did the transfiguration have on the apostle Peter?

⁵ The apostle Peter had already identified Jesus as “the Christ, the Son of the living God.” (Matthew 16:16) Jehovah’s words from heaven confirmed that identification, and the vision of Jesus transfigured was a foretaste of Christ’s coming in Kingdom power and glory, eventually to judge mankind. More than 30 years after the transfiguration, Peter wrote: “It was not by following artfully contrived false stories that we acquainted you with the power and presence of our Lord Jesus Christ, but it was by having become eyewitnesses of his magnificence. For he received from God the Father honor and glory, when words such as these were borne to him by the magnificent glory: ‘This is my son, my beloved, whom I myself have approved.’ Yes, these words we heard borne from heaven while we were with him in the holy mountain.”—2 Peter 1:16-18; 1 Peter 4:17.
