Salt is good; that is, it is useful and beneficial. This is true of the literal salt. Its wholesome antiseptic properties are universally recognized. But our Lord has before his mind in this whole passage the spiritual meaning. He is thinking of the salt of Divine grace, of the salt of a spirit informed and influenced by the Holy Spirit. He had already told his disciples that they were "the salt of the earth." Not, indeed, that they could deliver the earth from corruption—that was beyond their power. But when Christ had delivered it by his mighty sacrifice and the gift of his Spirit, it was their business, as it is the duty of all Christians, to keep it in a healthy state; so that by their wisdom and purity, their holy lives and holy teaching, they might season the whole world. But if the salt have lost its saltness ( ἐὰν τὸ ἅλας ἄναλον γένηται), wherewith will ye season it? This insipid, tasteless condition of salt is familiar to travelers in the East Examples are to be found of largo masses of salt which "has lost its savor." Our Lord here applies this in a spiritual sense to his disciples. "If ye, my disciples, who are the salt of the earth,—if ye lose the true properties of salt; if your Christianity loses its heart, its quickening, stimulating influence; so that on account of the love of the world, or the fear of man, or through lust or ambition, you fall away from the heavenly doctrine and life;—who shall restore you to your former spiritual health and vigor? With what can salt itself be seasoned when its own chemical energies are lost?" Our Lord plays upon this figure of salt, and cautions his disciples, lest by any means they should lose the qualities of this mystic salt. Have salt in yourselves, and be at peace one with another. This sentence fitly winds up the whole. Have the salt of wisdom and purity, and of a Christian life, namely, humility, charity, contempt of the world, and especially peace. Do not be idly contending about place or position, as not long ago you were disputing (Mark 9:33). Our Lord foresaw that this kind of contention, these rivalries, and these ambitious aims, would prove a great scandal and a great hindranee to the progress of his Church in the future ages of the world. But he also knew that if his disciples in every ago would endeavor to "keep the unity of the Spirit in the bond of peace," their influence would be irresistible, and they would draw all men to them and to himself, the great Centre of attraction, and "the confidence of all the ends of the earth" (Psalms 65:5).
