Twenty-first Sunday in Ordinary Time, Year A: Jesus and the Keys

Reflection for the Twenty-first Sunday in Ordinary Time, Year A – August 23, 2026

As we gather for the Twenty-first Sunday in Ordinary Time, the Church invites us to contemplate authority, faith, and the unsearchable wisdom of God. These readings follow closely on the Memorial of the Queenship of the Blessed Virgin Mary (August 22), offering a beautiful continuum: Mary, exalted as Queen of Heaven through her humble “yes,” points us toward the keys of the Kingdom entrusted by her Son.

In the first reading from Isaiah 22:19-23, the Lord deposes the unfaithful steward Shebna and elevates Eliakim, placing “the key of the House of David on Eliakim’s shoulder.” When he opens, no one shall shut; when he shuts, no one shall open. This image of stewardship and authority prefigures the Gospel. God chooses not the proud or self-promoting, but the one who will serve as a father to the people—a reliable peg fixed in a sure place. True authority is a gift for the building up of God’s household, not for personal glory.

Saint Paul’s hymn in Romans 11:33-36 deepens this mystery: “Oh, the depth of the riches and wisdom and knowledge of God! How inscrutable are his judgments and how unsearchable his ways!” All things are from him, through him, and for him. God’s plan often confounds human expectation. The same God who raised the lowly Virgin of Nazareth to the dignity of Queen Mother is the One who reveals the Messiah not through flesh and blood, but through the Father’s grace.

This revelation reaches its climax in the Gospel (Matthew 16:13-20). At Caesarea Philippi, Jesus asks, “Who do you say that I am?” Simon Peter’s inspired confession—“You are the Christ, the Son of the living God”—draws Jesus’ solemn reply: “You are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it. I will give you the keys to the kingdom of heaven.” The keys once promised to Eliakim are now given to Peter, establishing the enduring foundation of the Church. Authority here is rooted in faith, sustained by divine revelation, and ordered toward service and the binding and loosing of sin for the sake of salvation.

Peter and the Papacy

This passage stands at the heart of the Church’s teaching on the papacy. Jesus deliberately changes Simon’s name to Petros (Peter, “rock”) and declares that upon this rock He will build His Church. The gift of the keys evokes the authority of the royal steward in Isaiah—symbolizing full governing power in the household of the King. The power to bind and loose refers to the authority to teach, govern, and forgive sins in Christ’s name.From the earliest centuries, the Church has understood Peter as the first among the apostles, endowed with a unique primacy of leadership and pastoral care. This primacy did not end with Peter’s martyrdom in Rome; it continues in his successors, the Bishops of Rome. The Pope, as successor of Peter, serves as the visible principle of unity for the entire Church, the guardian of the deposit of faith, and the servant of the servants of God. 

Christ’s promise that the gates of hell shall not prevail against the Church is tied to this Petrine office: the rock remains firm because it is sustained by the Lord’s own word and the Holy Spirit.The papacy is therefore not a human invention or a claim to worldly power, but a gift of Christ for the safeguarding of the Gospel and the pastoral care of His flock. Like Eliakim of old, the Pope is called to be a father to God’s people—opening the doors of mercy, teaching with authority, and strengthening the brethren in faith. When we look to the Chair of Peter, we see not merely a man, but the enduring presence of Christ’s own pastoral care for His Church until the end of time.Just yesterday we celebrated Mary as Queen—crowned not by worldly power but by her intimate share in the redemptive work of her Son. As Queen Mother she intercedes for us with a mother’s solicitude, guiding us to the same Christ whom Peter confessed. Her queenship reminds us that the greatest in the Kingdom are those who humble themselves. Mary’s fiat made her the perfect disciple; 

Peter’s confession made him the rock. Both point us to Jesus, the true King, whose Church stands firm against every assault through the ministry of Peter’s successors.As we receive the Eucharist this Sunday, may we renew our own confession of faith. Who do we say that Jesus is—not merely with our lips, but with our lives? May Our Lady, Queen of Heaven and Earth, intercede for us, and may the successor of Peter continue to strengthen us in unity and truth, that we may remain faithful stewards of the keys entrusted to the Church, living in the unsearchable wisdom and eternal love of God. Lord, your love is eternal; do not forsake the work of your hands. Amen.
