Then He goes on to a higher example—_You are the light of the world_. It is again _of the world_; not of one people, nor of twenty cities, but of the whole world; and it is a reasonable light, far superior to this physical light, just as spiritual salt is to material salt. And first they are salt, and afterwards light, in order that you may learn the force of strong words and the advantage of this holy teaching. For it is urgent and will not be diverted from its aim, and, leading us by the hand, makes us look towards goodness. _A city seated on a mountain cannot be hidden. Neither do men light a candle and put it under a bushel._ He leads them once more through these things to purity of life, teaching them to be soldiers, as if before the eyes of all men and wrestling in the midst of the arena of the whole world. ‘Look not,’ He said, ‘to rest now whilst you are in a small corner; for you are to be visible to all men, like a city seated on a mountain, and like a candle shining upon all those in the house.’ Where, now, are they who have distrusted the power of Christ? Let them listen to these things, and, being frightened by the might of the prophecy, let them fall down and adore His almightiness. Think what great things He promised to those who were not known even in their native place: that they are to go over land and sea, and to lift up their voice against the temptations of the world, or rather not their voice, but the force of their goodness. For it was not their universal fame which made them conspicuous: it was the manifestation of works. As if they had had wings, they spread over the whole earth quicker than light, sowing the light of piety. Hence, it seems to me that He stimulates them unto fearlessness, for His saying, _A city seated on the mountain cannot be hidden_, was the manifestation of His own power; for, if it were useless to hide that, so neither could the Gospel tidings be hushed or concealed. And to prevent them from thinking that persecutions, and accusations, and plots, and wars, since He spoke of these things, would have power to check them, He encourages them by saying that not only these persecutions will not pass unnoticed, but that they will shine forth to the whole world, and that through this very fact they themselves were to be renowned and famous. In this, then, His own power is manifested; but He furthermore requires fortitude from each one of them, saying, _Men do not light a candle and put it under a bushel, but upon a candlestick, and it gives light to all in the house. So may your light shine before men, that they may see your good works and glorify your Father Who is in heaven._ ‘For it is I Who have enkindled the light,’ He says. Whether, however, it remains lighted or not must depend upon your zeal, not on your own account alone, but for the sake of those who are to enjoy this beacon, and whom it is to lead to the truth. For the slanderings of men will not be able to veil your
