The scriptures referred to are Isaiah 58:1-12, Psalm 112:1-9, 1 Corinthians 2:1-16, and Matthew 5:13-20.
I used to work for US-1 Radio as production director and copywriter. I was responsible for writing and recording the commercials, which paid everyone's salary. I won awards for my ads. But the station was most proud of a national award it got for its coverage during Hurricane Georges. They let me, my wife and our kids evacuate because they stopped running commercials and our news director Bill Becker and the on-air staff covered the hurricane 24 hours a day, even as water leaked into the studio. During Hurricane Irma, one of the staff stood outside in the storm holding the satellite dish in place, so the signal would get beamed to the tower and from there to people throughout the Florida Keys. If that dish had failed, what they were saying in the studio would not have mattered. The physical setup made spreading of the message possible.
Which would you miss first should they disappear from this place: Pastor Art and I bringing you communion or the trustees bringing you food? Access to Bibles or access to blankets? The chaplains or the nurses? I'm not saying that our spiritual needs are not important, but if a person doesn't have their physical needs met first, it is hard for them to focus on spiritual matters, however important.
Jesus knew that. Just before the Sermon on the Mount begins we read in Matthew, “Jesus went throughout Galilee, teaching in their synagogues and proclaiming the good news of the kingdom and curing every disease and every sickness among the people. So his fame spread throughout all Syria, and they brought to him all the sick, those who were afflicted with various diseases and pains, demoniacs, epileptics, and paralytics, and he cured them. And great crowds followed him from Galilee, the Decapolis, Jerusalem, Judea, and from beyond the Jordan.” (Matthew 4:21-25) Which do you think was more likely—that the crowds came to Jesus mainly to hear him preach and then maybe to stay and be healed? Or that they came first to be healed and then stayed to hear what the person who healed them had to say about God's love and forgiveness?
Very early a philosophy tried to infiltrate the church: Gnosticism. The name came from the Greek word for knowledge and that knowledge was that everything physical was evil and only what was spiritual was good. It attracted a lot of people. The most famous Gnostic work was the so-called Gospel of Thomas. The problem is that, according to the Gnostics, Christ did not really become one of us. He couldn't have a physical and therefore evil body, so the incarnation was an illusion. Which also meant he wasn't crucified and thus didn't die or rise again. They were illusions. Salvation came through learning the secret knowledge the Gnostics taught. There were levels of secret knowledge their followers had to ascend through, rather like Scientology. Lots of cults follow this plan.
Gnosticism was condemned as a heresy. But even in the mainstream church you find people who wish to separate the spiritual from the physical. They think the church should focus almost exclusively on spiritual matters. They say that the church shouldn't get involved in things like social justice. They even say that empathy can be a sin!
I wonder what they make of today's passage from Isaiah, the prophet Jesus quoted the most. Here God is saying that his people's religious fasts do not count with him and their prayers do not reach him if at the same time they are inflicting or even tolerating injustice. He wants them to first free the oppressed and share their food with the hungry and “bring the homeless poor into your house.” They are to clothe the naked and “satisfy the needs of the afflicted.” Only after that are we told “Then you shall call, and the Lord will answer; you shall cry for help, and he will say, 'Here I am'”
And in today's passage from the Psalms, the book of the Bible that Jesus quoted the most, we read that “the righteous are merciful and full of compassion. It is good for them to be generous in lending and to manage their affairs with justice...They have given freely to the poor.” The righteous, then, are not just concerned with spiritual matters but with physical matters as well, like helping the poor.
(By the way, empathy is a synonym for compassion. If the righteous are to be “full of compassion,” if God is described as compassionate (Exodus 34:6; Deuteronomy 4:31; Psalms 78:38; 86:15; 103:8), if Jesus is described as being moved by compassion (Matthew 9:36; 14:14; 15:32; 20:34), then empathy, another word for compassion, cannot be a sin.)
In our passage from the Sermon on the Mount, Jesus compares his followers to salt and light. What did he mean by that?
Today we think of salt primarily as adding flavor to foods. One of the problems heart patients and people with high blood pressure face when avoiding too much salt is that they find their diets have become bland. Look at any food packaging and you will generally find sodium (ie, salt) as one of the ingredients. Yet sodium is an important electrolyte that helps us regulate our fluid balance, blood pressure, nerve function and muscle contractions. So the trick is to maintain the proper balance between too much and too little. Balance, called homeostasis in biology, is vital to a healthy life.
Jesus however is probably thinking of the use of salt as a preservative. There was no such thing as refrigeration back then. Yes, rich people had ice cellars in which they kept snow and ice from the previous winter but usually this was used to cool beverages. The average person preserved perishable foods, like fish, by using salt. So Jesus is thinking of his followers as people who preserve the earth. How? Just previously he had described citizens of God's kingdom as being merciful and peacemakers among other things. People who are merciless and troublemakers do not preserve communities but fracture them. They destroy the trust which underlies all relationships. It's ironic that we talk about a “dog eat dog” society because dogs are intensely loyal to their packs and families and do not like conflict. My kids found to their amusement that if they pretended to fight our dog went nuts trying to stop them. It distressed her. She knew what some humans don't: peace and mercy are necessary to keeping a family and a community together. By showing mercy and making peace Jesus' followers keep the world from descending into conflict and chaos.
Then Jesus calls his followers “the light of the world.” Ever experience total darkness? I remember being on a commercial tour of a cave when the tour guide showed us what the cave looked like before they installed lighting. He turned all the lights off. We were plunged into absolute darkness. Even on nights when the moon is not visible, you can usually see a little. And in the modern world we typically have access to light. But when that cave went dark, it was as if everything ceased to exist. You could not see your hand or the person next to you or the cave floor or the guardrails that kept you on the path. Most people have never experienced total darkness. It is scary.
Light lets us navigate this world. It enables us to see things as they are. We can see the things that we need. We can see dangers ahead and we can see the path that is safe. We can see the faces of those we love and their expressions and their gestures. Jesus is saying that we are to act like light in those ways. We are to help others navigate this life. We are to reveal how things actually are. We are to point out dangers and the safe path that leads away from them. We are to express our love for others in all we say and do.
And doing loving things is a vital part of being the light of the world. Jesus says, “In the same way, let your light shine before others, so that they may see your good works and give glory to your Father in heaven.” Our good works reveal God's love. We are not saved by our works, but we are saved in order that we can do good works. As Paul writes in Ephesians, “For by grace you are saved through faith, and this is not from yourselves, it is the gift of God; it is not from works, so that no one can boast. For we are his workmanship, having been created in Christ Jesus for good works that God prepared beforehand so we might do them.” (Ephesians 2:8-10, emphasis mine) We are not Gnostics, just drinking in knowledge and no more involved in the physical world than necessary. We are to roll up our sleeves and reach out and help one another. How else will people see that the good news of God's love is more than mere words?
But didn't Jesus say of himself, “I am the light of the world”? So how is it that he tells us “You are the light of the world”? Indeed, he is the light of the world. And he continued, “The one who follows me will never walk in darkness, but will have the light of life.” (John 8:12) The light we show the world does not come from us but from Jesus. We mirror and reflect his light. Or think of us as lamps lit by his flame. A candle lit from another candle does not diminish the first candle and burns as brightly.
And when his critics did not believe him, Jesus said, “If I do not perform the deeds of my Father, do not believe me. But if I do them, even if you do not believe me, believe the deeds, so that you may come to know and understand that I am in the Father and the Father is in me.” (John 10:37-38) “If you do not believe me, believe the deeds.” Jesus wasn't asking for blind faith; the evidence that God was acting in him was in the deeds he did. He fed people and healed them and raised the dead. His works validated his words. Many a false prophet is betrayed by the fact that his evil works contradict whatever good words he says, not to mention the Word of God.
Paul seems to be playing with the idea of secret wisdom in our passage from 1st Corinthians. He talks of “God's wisdom, the hidden mystery...which none of the rulers of this age understood, for if they had they would not have crucified the Lord of glory.” In this case, he seems to be speaking not of those who neglect the physical for the spiritual but the opposite error: those who disregard the spiritual and so concentrate on physical power, which they use to harm and kill those they oppose. Jesus was executed because he was not only a threat to the religious leaders' authority but to the political leaders' control. Despite Jesus saying his kingdom did not come from this world Pilate charged him with being the King of the Jews, a rival to Caesar, who took the title king of kings. (John 18:36; 19:12, 19)
Worldly wisdom is about looking out for number 1: yourself. But God's wisdom is about looking out for others. It is centered in Christ crucified. This act of self-sacrificial love was not an illusion but is at the very heart of reality. Just as he fed people physical food and healed their physical bodies, he shed his physical blood and died a physical death. And when he talked of his disciples taking up their crosses and following him, he was not being metaphorical. Most were martyred and Peter was literally crucified. Though few of us today face that kind of sacrifice, the crosses we carry should be made evident in physical acts of love, like those spelled out in Isaiah: sharing what we have with the hungry and the homeless, not oppressing workers but freeing them from the bonds of injustice, not quarreling and fighting but satisfying the needs of the afflicted. Jesus did not come to abolish the message of the Law or the prophets but to fulfill them. And as the body of Christ, we must also fulfill them. Teaching people to disregard these commandments to show compassion and act justly may make you look strong and great in the eyes of the world but not in God's kingdom. As Paul says, all the commandments “are summed up in this, 'Love your neighbor as yourself.' Love does no wrong to a neighbor. Therefore love is the fulfillment of the law.” (Romans 13:9-10)
C.S. Lewis pointed out that we are amphibians, at home in both the physical and the spiritual realms. In Jesus, God Incarnate, both heaven and earth, the spiritual and the physical, meet. It is foolish to neglect either one. As the radio station could not get its message out without maintaining the physical setup needed to broadcast, we cannot expect the good news to reach people if we only use words and not actions of justice and compassion. And if, as some say, ours is a Christian nation, it cannot go about oppressing people, committing injustices, ignoring the needs of the poor, harming and abusing children (Matthew 18:5-6), not treating the alien as a native born (Leviticus 19:33-34), being merciless and creating trouble rather than making peace. That doesn't sound like the kingdom where the God who is love reigns. It sounds like hell. As Jesus said of his critics who condemned his deeds of compassion because he put people over man-made rules, “For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.”
