Jesus the Light of the World

Homily for the Third Sunday Year A

by Fr. Tommy Lane

When Jesus went up to Galilee after being baptized by John the Baptist, Matthew tells us this passage in Isaiah was fulfilled. Isaiah wrote:

The people who walked in darkness
have seen a great light;
upon those who dwelt in the land of gloom
a light has shone. (Matt 4:16)

John the evangelist wrote also about Jesus as the light when he wrote that the Word is the light that shines in the darkness, and the darkness has not overcome it (John 1:5). It is not just Matthew or John the evangelist saying Jesus is the light—Jesus himself described himself as the light. In John 8, on the last day of a Jewish festival, Jesus said, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.” (John 8:12) Jesus didn’t just say he was light—he was practical. The Gospels report Jesus giving sight to people in Galilee—the blind man in Bethsaida (Mark 8:22–26), two blind men in Galilee (Matt 9:27-31), a man who was blind and mute (Matt 12:22), and multiple blind people having their sight restored (Matt 15:30-31) Further south, Jesus gave sight to Bartimaeus in Jericho (Mark 10:46–52, Matt 20:29-34, Luke 18:35-43) and Matthew and John report Jesus healing the blind the temple (Matt 21:14; John 9). When Jesus said he is the light of the world, he was also practical and gave sight to all these people.

Jesus continues to be practical as we can see in an incident that is reported to have taken place in the shrine of Our Lady of Guadalupe. In the image of Our Lady, she is wearing the black maternity band tied in a ribbon high around her waist and there is a four-petal flower (Nahui Ollin) on her abdomen indicating to the Aztec people that she was pregnant carrying Jesus. Guadalupe, picture from press releaseIn 2007, within a week of the municipal council of Mexico City legalized taking the life of the unborn, an intense light emanated from Our Lady’s abdomen in the form of an embryo. The light was very white, pure, and intense, and different from regular lights produced by flash cameras. It had the form and measurements of an embryo. Looking at the light more closely showed that it had some areas of shade, like the characteristics of an Guadalupe, picture from press releaseembryo in the womb. Jesus is the light of world, challenging the darkness of the world. (Permission received in 2008 from ACIM, Association Catholique des Infirmières, Médecins et professionnels de la santé, to display the pictures on this website. I saved a report on the photographic negative here and here.)

Many believe that Jesus also showed himself to be the light of the world at the moment of his resurrection. The most studied artifact in the world is the Shroud of Turin, picture from rayofmercy.orgShroud of Turin. There is no technology in the world that can produce the image on it. The image of the crucified man is not paint or ink and is only on the surface of each fiber of the cloth; it has not penetrated beyond the surface of the fibers. When photography was invented, a big shock occurred because when the first photograph was developed in the dark room, it was like a negative rather than a photo, with light and dark reversed, and revealed details not visible to the naked eye. Yet, the cloth is from centuries before photography was invented. Also, the image indicates how far each part of the body of crucified man was from the cloth by the intensity of the image, like a 3-D image. Almost every test on the cloth is contested both ways by scientists and there is lots of fake news about it on the internet. But at the end of the day, we have to come back to where we started: there is no technology in the world that can produce that image. So what produced the image? The most common explanation is that it was a burst of light radiation at the moment of Jesus’ resurrection. It had to have been just the right amount because if it were not strong enough it would not have left the image on the cloth and if it were too strong it would have burned up the cloth. Of course, no one can say for definite it was the cloth over Jesus in the tomb at the moment of his resurrection, but perhaps we could apply to it this famous quote: “for those who believe, no proof is necessary. For those who don’t believe, no proof is possible.” When visiting it (May 24, 1998), Pope John Paul II said, “the imprint left by the tortured body of the Crucified One, which attests to the tremendous human capacity for causing pain and death to one’s fellow man, stands as an icon of the suffering of the innocent in every age.” (§4) He also said, “The Shroud is an image of God’s love as well as of human sin.” (§5) For an exposition of the shroud in 2013, Pope Francis recorded a video message in which he said, “the Man of the Shroud invites us to contemplate Jesus of Nazareth.” As we contemplate the shroud, we contemplate Jesus the light of the world.

Jesus is practical. He wants to enlighten every corner of your life. In the second reading today (1 Cor 1), the Corinthians had accepted Jesus but there were a lot of divisions among them as well as loads of other problems as we see in Paul’s letters. They still needed to allow Jesus to enlighten every corner of their lives. Can you allow the light of Jesus to shine on the Corinthian part of your life?
