“YOU ARE SALT ... LIGHT”
Isaiah 58:7-10; Matthew 5:13-16
AIM: To explain the images of
salt and light in the gospel
Jesus never talked over people’s
heads. He spoke in simple, everyday language that even children could
understand. What could be simpler than the two images Jesus uses in our gospel
reading: salt and light?
“You are the salt of the earth,”
Jesus says. The words are simple enough.
But what do they really mean?
A guest at a wedding was asked to
propose a toast to the bridal couple.
Before he did so he presented them with a beautifully crafted mahogany
box.
“Open it,” he told them.
When they did so, they saw it
contained salt.
“I have given that to you,” he said,
“because you’re going to need it. Salt adds flavor to food. You cannot keep
house without it. If you run out of toothpaste, you can use it, mixed with
soda, to brush your teeth. Salt mixed with hot water helps heal a sore throat
if you gargle with it. Before refrigeration was invented, salt was used to
preserve food. It is still used as a preservative in many parts of the world:
to cure fish and ham. You can use salt to melt ice on your front steps in
winter. And salt can also be used to smother a fire.”
“And now,” he said, “here is my toast. “May
you bring into your marriage all of salt’s properties — its ability to cleanse,
to heal, to preserve. May it melt the frost and ice that will sometimes build
up between you, and put out the fires of anger when you try each other’s
patience. Finally, as you embark on life in double harness, try to take things
with a grain of this salt. If there is salt in your marriage, it will be
healthy, lasting, and strong.”
In the ancient world in which Jesus
lived soldiers received an allotment of salt as part of their pay. Because the
Latin word for salt is sal it was called their salarium, from
which we get our word salary. Even today, when someone doesn’t measure
up or do his duty, we say he’s “not worth his salt.”
Jesus says to us: “You are the
salt of the earth.” We are to be that ingredient in the world which, like salt,
may be small in quantity, but which makes all the difference in quality. By
itself, of course, salt tastes quite different from the food to which it is
added. Jesus uses this image to tell us that we too must be different
from the world around us. We must live by different standards. Jesus gives us a description of those standards in those
sayings of his that are called the Beatitudes. They are Jesus’ recipe for
happiness. His way to happiness is very different from that of the world around
us. Where Jesus says, “Blessed are the poor in spirit,” for instance, the world
says “Blessed are the rich.”
Jesus also tells us: “You are light —
the light of the world.” The first creation tale in Genesis says that creation
began when God said: “Let there be light.” And the writer adds immediately:
“And God saw that the light was good.” (Gen. 1:3f).
When, in the fullness of time, God’s
Son came into the world, he said: “I am the light of the world.” (Jn 8:12) Pondering
those words, and the story of creation in Genesis, Christians came to discern
Christ’s role in creation. Hence we say in the Creed: “We believe in one Lord,
Jesus Christ, ... through whom all things were made.”
It is not difficult to understand
that Jesus is the world’s light. How dark the world would be if he had never
lived! To hear Jesus say, however, “You are the light of the world”
takes our breath away — or at least it would, if the words were not so familiar
to us.
Notice: Jesus does not tell us to become
the world’s light, any more than he tells us to become salt. As followers and
friends of Jesus Christ, given a share of his life in baptism, we already are
salt and light for the world. “Be what you are!” Jesus is saying.
Does that mean isolating ourselves as
much as possible from modern society and culture? In every age there have been
Christians who thought they must do that. They are good people. But they are
mistaken. To isolate ourselves from others is like putting the lamp which
lighted the small one-room house of Jesus’ day under a basket. The people who
heard Jesus knew that wasn’t what you did with a lamp. You put it on a
lampstand where, as Jesus says in today’s gospel, “it gives light to all in the
house. Just so,” Jesus continues, “your light must shine before others,
that they may see your good deeds and glorify ...” Glorify whom? You? No — that they may glorify God! Why? Because
without God we couldn’t do any good deeds. He is the one who inspires us
to do good deeds. And it is God, and God alone, who gives us the power to do
good — to be what we are: salt to cleanse, heal, and preserve; and light to
shine in the darkness of our world.
What kind of good deeds is Jesus
talking about? The words of the prophet Isaiah in our first reading tell us:
Share your bread with the hungry,
shelter the oppressed and the homeless; clothe the naked when you see them, and
do not turn your back on your own. ... remove from your midst oppression, false
accusation and malicious speech ... bestow your bread on the hungry and satisfy
the afflicted.
Isaiah addressed those words to
people who were scrupulous about the rules of religion, but too often
blind to the claims of humanity. The good deeds which Isaiah is talking
about point away from themselves and from us, to Him who first inspires and
then enables us to perform these deeds.
Today’s short gospel reading challenges
us. If our world is often dark; if modern society and culture often leave us
with a bad taste in our mouths; this is because we, the followers and friends
of Jesus Christ, too often fail to be what we became in baptism: the world’s
salt, the world’s light. The eighteenth-century British statesman, Edmund
Burke, said: “All that is necessary for evil to triumph in the world is for
good people to do nothing.”
Here at these two tables of word and
sacrament the Lord first takes us up into his light and then sends us forth to
pass on that light to others in a dark world, through a life of joyful service
and generous love.
