Light/Salt of the World

“‘Ye are the light of the world’ (Mt. 5:14). ‘Of the world’ again; not of one nation, nor of twenty states, but of the whole inhabited earth. And ‘a light’ to the mind, far better than this sunbeam: like as they were also a spiritual salt. And before they are salt, and now light; to teach thee how great is the gain of these strict precepts, and the profit of that grave discipline: how it binds, and permits not to become dissolute; and causes clear sight, leading men to virtue.” St. John Chrysostom.
