Today is the second of three consecutive days when I am presiding at the parish daily Mass. The three gospels are all taken from Matthew 5, the Sermon on the Mount. What follows is really one longer reflection delivered over three days because these three Gospel passages form a remarkably coherent sequence. They are not merely three disconnected sections of the Sermon on the Mount; they describe a progression in Christian discipleship:

• Who we are becoming (The Beatitudes) – yesterday
• What our lives are meant to do (Salt and Light) – today
• The foundation upon which we live (Fulfillment of the Law) – tomorrow

Together they form a unified theme: The Shape, the Mission, and the Foundation of the Christian Life.

In yesterday’s reflection, we noted that the Beatitudes remind us that God is not simply interested in improving our behavior. The challenge of the first reflection was: what kind of person is God shaping me to become? Jesus’ hope is that the transformation of our hearts will shape our lives as Christians. 

Our Lives Visible to the World

Today Jesus’ goal is to show us what happens when that Christian life becomes visible. Jesus tells the disciples, “You are the salt of the earth….You are the light of the world.” Notice that Jesus does not say, “You should try to become salt” or “You should try to become light.” He says, “You are.” Such is the commission of our Baptism. The question is whether we are living in a way that fulfills that identity.

Salt changes whatever it touches. Light transforms darkness simply by being present. That is what happens when the Beatitudes become real in a person’s life. A merciful person changes the atmosphere of a family. A peacemaker changes the atmosphere of a workplace. A person who hungers and thirsts for righteousness changes the atmosphere of a community. It is the difference between being a thermometer that just reflects the temperature of the room and being a thermostat that sets the temperature.

The world often imagines that such influence comes from power, wealth, status, or attention. Jesus offers another vision. The disciple influences the world not primarily through position, but through witness.

Think of the people who have most influenced your faith. They were probably not famous. They may have been a parent, grandparent, teacher, coach, friend, priest, or religious sister. Their influence came from the way they lived. Their lives were the salt that seasoned your life; the light that reflected Christ into your world.

That is what Jesus means when he says: “Your light must shine before others, that they may see your good deeds and glorify your heavenly Father.” The goal is not that people notice us. The goal is that people see something of God through us. What we have received from others, we pay forward by the lives we live.

Yesterday we asked: Who is God shaping me to become? Today we ask: What effect does that transformed life have on others? The answer is simple: a life formed by the Beatitudes becomes salt for and light that changes the world.
