Matthew 5:13-20
On Being Salt and Light

“You
are my sunshine, my only sunshine. You make me happy when skies are grey. You'll
never know, dear, how much I love you. Please
don't take my sunshine away.” For some reason this song
popped into my head when I was thinking about salt and light in our gospel
reading. I was wondering whether those words have the same impact they did in
Jesus’ time. They’re both rather mundane.
“Turn
on the light,” someone says, and we flip the switch. Light is everywhere. You
can’t see the stars very well at night in the DMV because there is so much
light. As long as the power doesn’t go out, we take it for granted, which may
be why I thought of the song. You are my sunshine sounds pretty impressive. I
get the metaphor of “You are the light of the world,” but it doesn’t sound as
impressive as sunshine
So
too with salt. A lot of us get too much of it. There’s nothing special about
salt. It’s nothing precious. No one would ever think of salt as an extravagant,
Valentine’s gift.
Yet
in ancient times, salt was often literally worth its weight in gold, one of the
most important commodities of the ancient world. It was used not only to season
food but to preserve it so it could be stored. It was used as an antiseptic; it
was required in the offerings made at the Jerusalem Temple. In some areas,
slabs of rock salt were used as coins.
Light
was also precious. In a world of candles and torches, oil lamps were cutting
edge technology. You had to buy oil to use them, and so no one lit a lamp and
put it under a bushel basket.
“You are the salt of the earth… You are
the light of the world.” Not something mundane or taken for
granted, but precious, valuable, essential for life.
