The Gospel is from St. Matthew 5:13-16. No less an authority than Christ himself calls his true followers the "salt of the earth." and the "light of the world." These are titles of honor, surely, and of the greatest distinction. Christ is putting his true follower on almost a level with himself. He was the light of the world; he was the salt of the earth. He it was who gave men the knowledge of the true nature of God, as shown by the Incarnation. He it was who gave this life its flavor, who gave this life its meaning, its preservation. By his death and resurrection he took away the sting of death, and removed its eternal corruption, by the guarantee and promise of a resurrection to an eternal life
In true humility, we can all say that we are far from worthy of any such honorable titles. Yet in all sincerity too, many if not the majority among us, are doing their little bit of Christ's work, in cultivating their own small corner of his vineyard. The parents who teach the Christian way of life to their children by word, and especially by example, are spreading the Christian faith. The workmen, whether in office or factory, who show that they are Christians by their honesty, charity for their fellowmen, their respect for God, and the things of God, in their speech, are spreading their Christian faith. All those who show moderation in their personal expenditures, and donate some of their savings to help their brothers, their fellowmen who are in need, these are true disciples of Christ and are cooperating with him in bringing God's children back to their Father who is in heaven.
Unlike the salt that has lost its flavor, and the light that is kept under the bushel, the Christian who has thus behaved can change his attitude, provided he is aided by God's grace which is never refused. He can become once more what he ought to be--a life-preserver for his neighbor.
Life on earth is short. The demands of our Christian life may not always be easy, but we know that if we live up to them, we are other Christs. We are continuing his great work by our own good example to our neighbor, and we are giving glory to God, and are earning for ourselves the eternal light of heaven.
