Thinking of obscure verses, I always wondered what Jesus meant by "if salt loses its savor". How can salt not be salt?
St. Augustine explained it in another way. Salt was the preservative in the ancient world which had no refrigeration. You wanted to keep food from spoiling, you "salted" it. Salt pork (bacon) is about the last of these we have, salt cod being about done for as a product.
let's go back to the context of this statement by Jesus. He's telling the apostles their job description. It is their job not only to baptize and bring forth to new birth the children of God, but to "preserve" them in grace to the end, for
he who perseverses will be saved. Thus he tells them that
you are the salt of the earth because it is their job as shepherds to guide the sheep to the end, to "preserve" them for heaven. If they do not do this, they are
good for nothing anymore but to be cast out, and to be trodden on by men. What is this but to be the subject of gossip and derision and wagging tongues. This is in contrast to the last beatitude which immediately preceeds this, which is
Blessed are ye when they shall revile you, and persecute you, and speak all that is evil against you, untruly, for my sake.
So He is saying that there are
two ways to be persecuted and reviled. One for doing His will, and one for
not doing his will. It's only a blessing when it is
untrue.
