“Vos estis sal terræ. Quod si sal evanuerit, in quo salietur ? ad nihilum valet ultra, nisi ut mittatur foras, et conculcetur ab hominibus.”
“Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.”
“You are the salt of the earth. But if the salt loses its savor, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled by men.”
““You are the salt of the earth, but if the salt has lost its flavor, with what will it be salted? It is then good for nothing, but to be cast out and trodden under the feet of men.”
“Ye are the salt of the earth: but if the salt have lost its savor, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out and trodden under foot of men.”
The former instructions Jesus Christ gave to the multitude. Now he addresses his apostles, styling them the salt of the earth, meant to preserve men from the corruption of sin, and to make them relish the truths of salvation. He tells them not to suffer their faith or their charity to slacken, in which all their power consists, lest they come to be rejected by God, and despised by man. (Calmet) — I send you, says Jesus Christ, not to two, ten, or twenty cities, not to one single nation, as the prophets were sent, but to the whole world, a world oppressed with numberless iniquities. It is not the property of salt to restore what is already corrupted, but to preserve from corruption. Therefore the virtue of the merits of Christ delivers us from the corruption of sin; but the care and labour of the apostles preserves us from again returning to it. (St. Chrysostom, hom. xv.) — It appears from Luke xiv. 34, that this comparison is taken from agriculture. We observe these properties of salt in the different manures that fertilize the soil, but suffer the salts to evaporate, and all their virtue is lost. (Haydock)
Be so far from being troubled, as to count it all joy, when you fall into these trials, Jas 1:2. Let it be music in your ears to hear that the drunkards make you their song. Rejoice in your hearts, express it in your lips and behaviour, not of debt, but of grace; for our light and momentary afflictions are not worthy to be compared with an eternal and exceeding weight of glory; where there is no proportion, there can be no merit: especially, when it is given to us on the behalf of Christ to suffer, Php 1:29. Peter upon this argument saith, The spirit of glory and of God resteth upon you, 1Pe 4:14. Our Saviour adds, The magistrates, and the rulers of the Jews, persecuted Elijah, Micaiah, Jeremiah, Amos, and the rest of the prophets, whom you succeed, not in time only, but in the same office of revealing the mind of God to the people.
4. It is designed to settle and sum up the articles of agreement between God and man. The scope of the divine revelation is to let us know what God expects from us, and what we may then expect from him; and no where is this more fully set forth in a few words than here, nor with a more exact reference to each other; and this is that gospel which we are required to believe; for what is faith but a conformity to these characters, and a dependence upon these promises? The way to happiness is here opened, and made a highway (Isa 35 8); and this coming from the mouth of Jesus Christ, it is intimated that from him, and by him, we are to receive both the seed and the fruit, both the grace required, and the glory promised. Nothing passes between God and fallen man, but through his hand. Some of the wiser heathen had notions of blessedness different from the rest of mankind, and looking toward this of our Saviour. Seneca, undertaking to describe a blessed man, makes it out, that it is only an honest, good man that is to be so called: De vita beata. cap. 4. Cui nullum bonum malumque sit, nisi bonus malusque animus—Quem nec extollant fortuita, nec frangant—Cui vera voluptas erit voluptatum comtemplio—Cui unum bonum honestas, unum malum turpitudo.—In whose estimation nothing is good or evil, but a good or evil heart—Whom no occurrences elate or deject—Whose true pleasure consists in a contempt of pleasure—To whom the only good is virtue, and the only evil vice.
Verses 13-16 Ye are the salt of the earth. Mankind, lying in ignorance and wickedness, were as a vast heap, ready to putrify; but Christ sent forth his disciples, by their lives and doctrines to season it with knowledge and grace. If they are not such as they should be, they are as salt that has lost its savour. If a man can take up the profession of Christ, and yet remain graceless, no other doctrine, no other means, can make him profitable. Our light must shine, by doing such good works as men may see. What is between God and our souls, must be kept to ourselves; but that which is of itself open to the sight of men, we must study to make suitable to our profession, and praiseworthy. We must aim at the glory of God.
