(Mt 5: 13-16)
Jesus said to his disciples:
“You are the salt of the earth.
But if salt loses its taste, with what can it be seasoned?
It is no longer good for anything
but to be thrown out and trampled underfoot.
You are the light of the world.
A city set on a mountain cannot be hidden.
Nor do they light a lamp and then put it under a bushel basket;
it is set on a lampstand,
where it gives light to all in the house.
Just so, your light must shine before others,
that they may see your good deeds
and glorify your heavenly Father.”
Salt and light are good metaphors of what we are supposed to be in this world. Salt purifies impurities. It kills bacteria that sets in decay to fresh food. Thus it also preserves. And so as salt we are enjoined to kill all things that lead to sin and to decay both in the moral and spiritual realms. We are also enjoined to preserve the teachings of the Lord. In world and deed they must be proclaimed for others to know.
As light, we prevent others from stumbling. They need not grope in the dark trying to find the way to Jesus. Our light, though feeble it is because of our weak faith, is enough to guide them and prevent them from getting lost. And even if we are far, our light shining in the dark is a beacon of hope for others.
