September 21, 2024 – Called to Unity and Mercy in Today’s Mass Readings

A Call to Unity, Ministry, and Mercy

Today’s readings interweave themes that are central to the Christian life: unity, vocation, and mercy. Each reading offers a unique reflection on how we are called to build up the Body of Christ, embrace the gifts we’ve been given, and show mercy to others. At their core, these passages remind us that we are all part of a larger community—the Church—where each of us plays a vital role in furthering God’s Kingdom.

St. Paul’s letter to the Ephesians emphasizes the importance of living a life worthy of our Christian calling, urging us to maintain the unity of the Spirit. Psalm 19 offers a poetic reminder that God continuously reveals Himself through creation—showing us how the whole world declares His glory, even without words. Lastly, Matthew’s Gospel presents the radical call of Matthew, a tax collector, highlighting Jesus’ mission to bring mercy to sinners and outcasts.

These readings challenge us to examine our lives: Are we fostering unity? Are we using our gifts for the good of others? Are we extending mercy to those around us? Through today’s Scripture, we are invited to reflect on the vastness of God’s love and the depth of His call to each of us.

First Reading – Ephesians 4:1-7, 11-13

Called to Build the Body of Christ: Unity in Diversity

Paul’s letter to the Ephesians is one of his most profound teachings on the nature of the Church and Christian community. Written from prison, the letter urges both Jewish and Gentile converts to live in unity despite their differences. Ephesus, a bustling and diverse city, faced the challenge of integrating people from different cultures and religious backgrounds. Paul’s message, however, transcends the context of the early Church and speaks to us today: We are all part of one Body, united by one Spirit, called by one Lord, and redeemed through one faith and one baptism.

Historically, the early Church grappled with divisions as it welcomed converts from various traditions. Jewish Christians often adhered to Mosaic law, while Gentile Christians did not, creating tension. Paul emphasizes that this diversity in backgrounds is part of God’s design, and all members of the Church—no matter their role—are called to contribute to the building up of the Body of Christ.

Ephesians 4:1-7, 11-13
New Revised Standard Version Catholic Edition

Unity in the Body of Christ
I therefore, the prisoner in the Lord, beg you to lead a life worthy of the calling to which you have been called, with all humility and gentleness, with patience, bearing with one another in love, making every effort to maintain the unity of the Spirit in the bond of peace. There is one body and one Spirit, just as you were called to the one hope of your calling, one Lord, one faith, one baptism, one God and Father of all, who is above all and through all and in all.
But each of us was given grace according to the measure of Christ’s gift.

11 The gifts he gave were that some would be apostles, some prophets, some evangelists, some pastors and teachers, 12 to equip the saints for the work of ministry, for building up the body of Christ, 13 until all of us come to the unity of the faith and of the knowledge of the Son of God, to maturity, to the measure of the full stature of Christ.

Detailed Exegesis

Verse 1: “I therefore, the prisoner in the Lord, beg you to lead a life worthy of the calling to which you have been called.”

Paul, referring to himself as a “prisoner in the Lord,” reminds the Ephesians that his faithfulness to Christ has led to imprisonment. His plea to “lead a life worthy” underscores that being Christian is more than just professing belief—it is a call to live in a way that reflects God’s love and holiness. The Catechism of the Catholic Church (CCC) teaches that “the dignity of the human person is rooted in his creation in the image and likeness of God” (CCC 1700), a dignity that calls us to reflect God’s grace in our lives.

Verse 2: “With all humility and gentleness, with patience, bearing with one another in love.”

Humility, gentleness, and patience are key virtues that foster unity. Paul’s call to bear with one another in love speaks to the Christian concept of agape—self-sacrificial love. St. Augustine reflected on this virtue, saying, “It was pride that changed angels into devils; it is humility that makes men as angels.” Love is the foundation for maintaining peace and unity within the Church.

Verse 3: “Making every effort to maintain the unity of the Spirit in the bond of peace.”

Unity within the Church requires intentional effort. Paul urges the Ephesians to strive for peace and maintain unity, a unity rooted in the Holy Spirit. The Catechism echoes this, teaching that the Church’s oneness is grounded in the unity of the Triune God (CCC 813). This verse invites us to reflect on how we contribute to unity in our own communities. Are we peacemakers, or do we cause division?

Verse 4-6: “There is one body and one Spirit, just as you were called to the one hope of your calling, one Lord, one faith, one baptism, one God and Father of all, who is above all and through all and in all.”

Paul declares the unity of the Christian faith: one Body (the Church), one Spirit (the Holy Spirit), one hope (eternal life), one Lord (Jesus Christ), one faith, and one baptism. The Catechism reflects this teaching, noting that the Church is the “visible plan of God’s love for humanity” (CCC 776). Despite our differences, we are all united in this divine plan, called to live as one in Christ.

Verses 7, 11-13: “But each of us was given grace according to the measure of Christ’s gift… The gifts he gave were that some would be apostles, some prophets, some evangelists, some pastors and teachers, to equip the saints for the work of ministry, for building up the body of Christ.”

While unity is essential, Paul also emphasizes the diversity of gifts within the Church. Each of us has been given a unique role to play, whether as an apostle, prophet, teacher, or pastor, all for the “building up” of the Body of Christ. The Catechism notes, “The unity of the Body of Christ does not do away with the diversity of its members and functions” (CCC 791). Our diverse gifts are necessary for the flourishing of the Church.

Reflection: Embracing Our Unique Calling

This passage encourages us to reflect on our role in the Church. How are we contributing to the building up of the Body of Christ? Are we fostering humility, love, and peace in our relationships? How can we use our unique gifts to foster unity in our community today? God calls each of us to live a life worthy of our calling, and that begins with recognizing the importance of unity and diversity within the Church.

Responsorial Psalm – Psalm 19:2-5

Creation Declares the Glory of God

Psalm 19 is a poetic reflection on how creation itself declares the glory of God. The psalmist meditates on the natural world’s ability to reveal God’s majesty without using words. This idea of “natural revelation” refers to how the beauty and order of creation point to God’s existence and power. As St. Bonaventure said, “In everything, no matter how small, we see God.”

Throughout history, this Psalm has been interpreted as a testimony to God’s universal revelation. Unlike the Law, which was given specifically to the Israelites, creation speaks to all people, regardless of their background or knowledge of Scripture.

Psalm 19:2-5
New Revised Standard Version Catholic Edition

Day to day pours forth speech,
    and night to night declares knowledge.
There is no speech, nor are there words;
    their voice is not heard;
yet their voice goes out through all the earth,
    and their words to the end of the world.
In the heavens he has set a tent for the sun,
which comes out like a bridegroom from his wedding canopy,
    and like a strong man runs its course with joy.

Detailed Exegesis

Verse 2: “Day to day pours forth speech, and night to night declares knowledge.”

The psalmist beautifully describes how each day and night reveals God’s glory. Although creation does not speak with words, its message about the Creator is constant and clear. St. Thomas Aquinas reflected that nature reveals God through its existence and order, writing that “the heavens declare the glory of God, for all the creatures reflect His beauty and greatness.”

Verse 3: “There is no speech, nor are there words; their voice is not heard.”

Although creation does not literally speak, its testimony is unmistakable. The Catechism reminds us that God can be known “with certainty from the created world by the natural light of human reason” (CCC 36). Nature’s beauty and order reflect the Creator, and sometimes, it is in silence that we best hear God speaking to us.

Verse 4: “Yet their voice goes out through all the earth, and their words to the end of the world.”

The message of creation is universal. No matter where we are in the world, we can witness the evidence of God’s existence in the natural world. This verse also foreshadows the spread of the Gospel, which would eventually reach all nations, carrying the message of salvation to every corner of the earth.

Verse 5: “In the heavens he has set a tent for the sun, which comes out like a bridegroom from his wedding canopy, and like a strong man runs its course with joy.”

The sun is compared to a bridegroom, an image full of life and joy. Just as the sun rises and sets each day, bringing light to the world, so too does Christ, the Bridegroom, bring new life to His Church. This joyful imagery reminds us of God’s faithfulness and His love for creation, especially for us, His children.

Reflection: Seeing God in Creation

This Psalm calls us to pause and appreciate the beauty of creation, seeing it as a reflection of God’s glory. Do we take time to notice God’s presence in the world around us? How can we become more attentive to the ways God speaks to us through nature? Whether it’s watching a sunset or walking through a garden, these moments offer a chance to encounter God in the beauty He has created.

Holy Gospel – Matthew 9:9-13

The Call of Matthew: Jesus Calls the Outcast

In today’s Gospel, Jesus calls Matthew, a tax collector, to follow Him. In Jewish society, tax collectors were considered traitors and sinners because they worked for the Roman Empire and were often associated with greed and corruption. Yet, Jesus invites Matthew into discipleship, demonstrating that no one is beyond God’s mercy.

Matthew’s calling is a powerful example of how Jesus came to save the lost and the broken. By choosing Matthew, Jesus shows that He came not to call the righteous but sinners, inviting those who are far from God into a life of grace and transformation.

Matthew 9:9-13
New Revised Standard Version Catholic Edition

The Call of Matthew
As Jesus was walking along, he saw a man called Matthew sitting at the tax booth; and he said to him, “Follow me.” And he got up and followed him.
10 And as he sat at dinner in the house, many tax collectors and sinners came and were sitting with him and his disciples. 11 When the Pharisees saw this, they said to his disciples, “Why does your teacher eat with tax collectors and sinners?” 12 But when he heard this, he said, “Those who are well have no need of a physician, but those who are sick. 13 Go and learn what this means, ‘I desire mercy, not sacrifice.’ For I have come to call not the righteous but sinners.”

Detailed Exegesis

Verse 9: “As Jesus was walking along, he saw a man called Matthew sitting at the tax booth; and he said to him, ‘Follow me.’ And he got up and followed him.”

Without hesitation, Jesus calls Matthew, a known sinner, to follow Him. Matthew’s immediate response—leaving everything behind—speaks to the power of Jesus’ invitation. The Catechism teaches that Christ’s call is extended to all people, no matter their background (CCC 541). This moment reminds us that God’s grace can transform anyone, regardless of their past.

Verse 10: “And as he sat at dinner in the house, many tax collectors and sinners came and were sitting with him and his disciples.”

Jesus not only calls Matthew but shares a meal with him and other sinners. This act was scandalous to the religious leaders of the time, who believed that associating with sinners made one impure. Jesus, however, shows us that true holiness is found in extending mercy to the outcasts, rather than separating ourselves from them.

Verse 11: “When the Pharisees saw this, they said to his disciples, ‘Why does your teacher eat with tax collectors and sinners?’”

The Pharisees represent a rigid, legalistic understanding of holiness, one that focuses on external purity rather than internal transformation. Their question reveals their misunderstanding of Jesus’ mission. Do we sometimes judge others in the same way, focusing on their sins rather than offering them mercy?

Verse 12: “But when he heard this, he said, ‘Those who are well have no need of a physician, but those who are sick.’”

Jesus responds by likening Himself to a physician—His mission is to heal the spiritually sick. Just as a doctor focuses on those who are ill, Jesus focuses on sinners, bringing them back to spiritual health. The Catechism reminds us that the Church is like a hospital for sinners, where we all come to be healed by God’s grace (CCC 1422).

Verse 13: “Go and learn what this means, ‘I desire mercy, not sacrifice.’ For I have come to call not the righteous but sinners.”

Here, Jesus quotes Hosea 6:6, emphasizing that God values mercy over ritual sacrifices. The Pharisees, focused on external observance, miss the heart of God’s message: true holiness is found in extending mercy to others. The Catechism teaches that “works of mercy are charitable actions by which we come to the aid of our neighbor” (CCC 2447). Jesus invites us to follow His example by prioritizing mercy over judgment.

Reflection: Responding to the Call of Mercy

Matthew’s story is a powerful reminder that no one is beyond the reach of God’s mercy. Just as Jesus called Matthew, He calls each of us to follow Him, regardless of our past mistakes. How can we extend mercy to those around us, especially those who feel marginalized or rejected? Jesus invites us to be instruments of His mercy in a world that desperately needs it.

Unity, Giftedness, and Mercy

Today’s readings deliver a profound message about living out our Christian calling. St. Paul reminds us of the importance of unity within the Church while also recognizing the diversity of gifts that God has given each of us. Psalm 19 challenges us to see God’s glory in creation, and the Gospel of Matthew reveals Jesus’ heart for sinners, reminding us that we are all called to extend mercy to others.

As we move forward in our spiritual journey, let us strive to foster unity, use our unique gifts for the good of others, and show mercy to those in need. How is God calling you to respond to His invitation today? Just as Jesus called Matthew, He calls each of us to follow Him in a life of transformation, love, and service.
