This Sunday is the Fifth Sunday of Ordinary Time. The Gospel reading is from Matthew 5:13-16; Jesus tells His apostles to be the salt of the earth, light of the world. Salt is useful for preserving food, so Jesus says that whoever lives out the Beatitudes will preserve the goodness of the world, or else they will be like salt that has lost its taste and is useless. In the Jewish tradition, Israel is to be the light of the nations. When Jesus tells His apostles to live out the Beatitudes, He is telling them to make Israel glorify God. Whenever Christians intentionally give witness to Christ, the whole world benefits. St. John Chrysostom once said that if all men acted as Christians ought, then even if they did not become saints, then the world would still be changed for the better. There would be morality, happiness, and peace. Christians not only have a duty to sanctify themselves, but to help others become holy and bring out their goodness and grow closer to God. In the Mass, we not only pray for ourselves and our families, but also for the world. We should lift up our colleagues, classmates, and friends to God with our prayers. We are called to care for the needs of others, not only their bodily needs, but also spiritual needs.
