On September 27, 2026, the Church observes the Twenty-Sixth Sunday in Ordinary Time, Year A. The readings address conversion, repentance, humility, and the difference between religious words and obedient action. In Matthew’s Gospel, Jesus presents two sons: one refuses his father’s request but later changes his mind and works in the vineyard; the other promises obedience but does not act.

This Catholic daily reflection considers how genuine faith becomes visible through conduct. Although the date falls during Ordinary Time, the message also serves as a valuable form of Advent preparation: the season of Advent calls the faithful to recognize Christ’s coming, examine the direction of life, and act upon the demands of the Gospel.

The Son Who Changed His Mind

The Gospel begins with a direct request from a father: “Son, go out and work in the vineyard today.” The first son responds, “I will not,” but later changes his mind and goes. The second son answers, “Yes, sir,” but does not go.

Jesus then asks which son did the father’s will. The answer is clear: the son whose actions fulfilled the father’s command.

The parable does not present disobedience as virtuous. The first son’s initial refusal remains a refusal. However, the son does not allow his first answer to determine the rest of his life. He reconsiders, turns away from disobedience, and enters the vineyard.

This is the central movement of conversion. Repentance is not merely regret over a past decision. It is a change of direction that leads to a different course of action.

Words and Deeds

Matthew 21:28-32 exposes the gap that can exist between religious language and lived obedience. The second son speaks respectfully and appears compliant, but his promise produces no work. The first son speaks harshly at first, yet his later action fulfills the father’s will.

The Gospel therefore asks a practical question: What does a person actually do after making a profession of faith?

Catholic spirituality does not separate belief from conduct. Prayer, worship, moral responsibility, service, and care for others belong together. A verbal “yes” to God requires concrete expression in daily life. The Christian vocation is not completed by correct speech alone.

This teaching also provides a warning against spiritual complacency. Familiarity with religious practice, knowledge of Scripture, or membership in a religious community cannot replace conversion of heart. The Gospel measures obedience not by appearance, but by fidelity.

The Mercy of a New Beginning

The First Reading from Ezekiel provides the theological foundation for the Gospel. The Lord does not treat a sinful past as an unchangeable identity. When a wicked person turns away from sin and begins to do what is right and just, that person receives life.

This teaching reveals both the seriousness of sin and the reality of divine mercy. Sin damages communion with God and neighbor, but repentance opens a way forward. The past is not ignored; rather, the person is called to leave behind the actions that caused harm.

The Responsorial Psalm expresses this disposition through a prayer for guidance:

“Your ways, O LORD, make known to me;
teach me your paths.”

The psalmist does not claim self-sufficiency. The faithful person asks to be taught, guided, and corrected. The Lord “shows sinners the way” and “guides the humble to justice.” Humility makes conversion possible because humility allows a person to acknowledge error and receive direction.

The Humility of Christ

The Second Reading, Philippians 2:1-11, places the parable within the wider pattern of Christ’s obedience. Saint Paul presents Jesus Christ as the one who “emptied himself,” took the form of a servant, and humbled himself through obedience, even to death on a cross.

The humility of Christ is not weakness or passivity. It is an active surrender to the will of the Father and a complete orientation toward the salvation of others. Christ’s obedience is expressed through concrete action.

Saint Paul therefore calls the Christian community to share the same attitude:

• Rejecting selfish ambition and vainglory.
• Regarding others with humility.
• Looking beyond personal interests.
• Seeking unity in Christ.
• Allowing faith to shape conduct.

The son who changes his mind and enters the vineyard offers one image of obedience. Christ offers the perfect image. His entire life reveals what it means to hear the Father’s will and carry it out.

Advent Preparation: A Change That Takes Shape

The language of the Gospel is especially appropriate for reflection during Advent. Advent preparation is not limited to external arrangements or seasonal observances. It involves a spiritual examination of whether the Christian life corresponds to the faith professed.

The phrase “changed his mind” can also be understood as a change of heart, purpose, and direction. Advent invites the faithful to consider:

• Whether neglected responsibilities require renewed attention.
• Whether an apology or act of reconciliation has been delayed.
• Whether prayer has become merely verbal rather than relational.
• Whether concern for the poor and vulnerable has become concrete.
• Whether the needs of the Church have been met with action rather than intention.

The Gospel does not demand that the faithful deny past failures. It demands a response to grace. The son’s first answer was not the final word. A person who has resisted God can still enter the vineyard through repentance and obedience.

The Eucharist and the Obedience of Christ

The Eucharist makes present the sacrificial obedience of Jesus Christ. At Mass, the Church receives the Body and Blood of the Lord, who offered himself to the Father for the salvation of the world.

An Eucharist reflection Catholic tradition recognizes that participation in the liturgy calls for a corresponding life of charity and service. The Eucharistic sacrifice cannot be reduced to an external religious observance disconnected from conduct. The faithful are sent from the altar to live according to the self-giving love received in the sacrament.

The Eucharist therefore raises a serious question: Does participation in Sunday worship lead to greater obedience, humility, and concern for others?

Christ’s self-emptying in Philippians 2 provides the measure. The Eucharist forms a people capable of entering the vineyard, accepting responsibility, and serving the mission of the Church. The response to God is not completed by saying “yes” at the level of intention. It must become visible in acts of mercy, justice, reconciliation, and missionary cooperation.

Missionary Responsibility and the Formation of Local Clergy

The vineyard in the Gospel can also represent the Church’s missionary field. Christ sends the entire Church to proclaim the Gospel and to support communities where the Church is young, poor, or unable to sustain its own structures.

The Society of St. Peter the Apostle serves this missionary responsibility by supporting the formation of indigenous clergy and religious vocations in mission territories. The Society was founded in 1889 through the efforts of Stephanie and Jeanne Bigard, a mother and daughter in France, in response to a request from Bishop Jules-Alphonse Cousin, MEP, Vicar Apostolic of Southern Japan and later Bishop of Nagasaki.

Bishop Cousin recognized the importance of forming a local clergy but faced serious financial limitations. Young men with signs of a priestly vocation could not always be admitted or adequately formed. The response of Stephanie and Jeanne Bigard helped establish a lasting work dedicated to the development of priests, religious brothers, and sisters from within mission communities.

Today, the Society supports:

• Ordinary subsidies for the daily needs and formation of seminarians, novices, and religious sisters.
• Extraordinary subsidies for constructing and renovating seminaries.
• Self-sustainability projects that strengthen the long-term life of local Churches.
• Mass intentions to assist seminary formators.
• Scholarships for future seminary educators.

This work reflects the Gospel’s emphasis on action. Missionary responsibility requires more than admiration for the Church’s global mission. It requires practical support for the people who will serve their own communities as priests, religious, and educators.

Prayerful Resolutions for September 27

A prayerful resolution arising from the readings may include:

• A sincere examination of the difference between stated intentions and actual conduct.
• A specific act of repentance regarding a neglected duty or harmful habit.
• A renewed commitment to daily prayer and attentive listening to the Word of God.
• An act of humility that places another person’s legitimate needs before personal preference.
• A concrete contribution to the formation of seminarians and religious in mission territories.
• A decision to approach the Eucharist with greater reverence and a stronger commitment to Christian service.

The Gospel leaves room for a new response. The first answer does not need to be the final answer. Through grace, repentance can become obedience, and obedience can become service.
