JC - Chapter 17

At His sermon on the mount, the Savior taught His disciples -

"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."  New Testament | Matthew 5:13)

Of such, Elder Talmage writes -

"The Master next proceeded to instruct with particular directness those upon whom would devolve the responsibility of the ministry as His commissioned representatives. “Ye are the salt of the earth,” said He. Salt is the great preservative; as such it has had practical use since very ancient times. Salt was prescribed as an essential addition to every meat offering under the Mosaic law.  Long before the time of Christ, the use of salt had been accorded a symbolism of fidelity, hospitality, and covenant.  To be of use salt must be pure; to be of any saving virtue as salt, it must be salt indeed, and not the product of chemical alteration or of earthy admixture, whereby its saltiness or “savor” would be lost;  and, as worthless stuff, it would be fit only to be thrown away. Against such change of faith, against such admixture with the sophistries, so-called philosophies, and heresies of the times, the disciples were especially warned."
