Matthew 5:13-16

Disciple functions. It is quite credible that these sentences formed part of the Teaching on the Hill. Jesus might say these things at a comparatively early period to the men to whom He had already said: I will make you fishers of men. The functions assigned to disciples here are not more ambitious than that alluded to at the time of their call. The new section rests on what goes before, and postulates possession of the attributes named in the Beatitudes. With these the disciples will be indeed the salt of the earth and the light of the world. Vitally important functions are indicated by the two figures. Nil sole et sale utilius was a Roman proverb (Pliny, H. N., 31, 9). Both harmonise with, the latter points expressly to, a universal destination of the new religion. The sun lightens all lands. Both also show how alien it was from the aims of Christ to be the teacher of an esoteric faith.
