The readings for the 13th Sunday After Pentecost, Yr. A were: Isaiah 51:1-6; Psalm 138, Romans 12:1-8; Matthew 16:13-20. This sermon was preached at Grace & Glory Lutheran Church in Palmyra, VA on August 23, 2026.
Today with the din of recent Jewish faith discussions and debates still echoing in his ears, Jesus pauses to asks his friends, “Who do people say the Son of Man is?” That term, “Son of Man,” is steeped in Jewish tradition and theology. In both Jewish and Christian scriptures, the term could indicate the humility of a mere mortal in comparison to God’s glory. It could be used as an address by God speaking to some prophets, or it is used be Jesus roughly seventy-eight times when referring to himself.[i] So, we might assume that term is pretty important.
In using the Son of Man title, Jesus echoes an image from a vision first given to the Prophet Daniel. One “like the Son of Man” would be “given dominion and glory and a kingdom, that all peoples, nations, and languages should serve him; his dominion is an everlasting dominion, which shall not pass away, and his kingdom one that shall not be destroyed” (Daniel 7:14). Thus, Jesus is subtly embodying and claiming that role for himself. He’s the savior. He’s the Lord.
Then, Jesus further reveals himself through his authentic teaching and preaching. He speaks as if with authority…as if he is God. Jesus embodies this authority as he heals the sick, exorcises demons, calms seas, feeds multitudes in miraculous ways, and resurrects people. Jesus used this title to affirm his authority to forgive sins (Mark 2:10 for example) and act as Lord of the Sabbath (Mark 2:28). Those with the eyes to see, as empowered by the Spirit, will recognize Jesus as Lord.
Yet, many people misjudge Jesus. Just a few verses before, Pharisees and Sadducees came to Jesus to challenge him. Normally adversarial factions within Judaism, debating about religious practice, scripture, and authority among the people of Israel, they have now become united in their opposition to Jesus…over their concerns about Jesus.[ii]
And as for the general population, as can happen in our own time under social stress, many people fear the End was near as they look at the state of the world around them. Jerusalem was under Roman rule. The Herodian Dynasty was friendlier to Greek ideals than Jewish ones, and they were vassals to Rome. People longed for freedom and the fulfillment of God’s eschatological, if not apocalyptic, promises.
In such a state, some like the Essenes lived extreme lives in the desert sharing in what we might today label a kind of a cultish, communal life. Other people claimed to be or were wrongly identified as the promised Messiah as they rallied people to fight Rome for liberty. This violence helped lead to the military occupation of Judah and the arrival of Pontius Pilat. And many prophets appeared; not all recorded in scripture. Some of these proved false prophets, much as some are appearing in our own time.
In this mix, John the Baptist served and died. We understand now that he prepared the way for Jesus, but at the time, he was primarily recognized as a great prophet in his own right. Some held out hope that he was the Messiah, so maybe…just maybe…John the Baptist would fulfill God’s past promised and come back to life.
Now, this might sound strange to us, but recall that to this day, a small Gnostic group called the Mandaeans who still view John the Baptist as their greatest and ultimate prophet.[iii] To them, Jesus is a false prophet. And in our own nation, a small sect of Hassidic Jews believes their rabbi who died in 1994 is the Messiah. They await his resurrection to complete their redemption.[iv] They think he is the promised Messiah. Likewise, there was and remains a belief that Elijah or Jeremiah would come back when it came time for God’s promises to Israel to be fulfilled. Throughout time, people have and will wrongly place their hope in figures other than Jesus.
That said, surrounded by Pagan temples to false gods, Jesus asks another important question…perhaps the most important eternally. “But who do you think that I am?” In my mind’s eye, I see the great Apostles hesitate. They might even be visibly hemming and hawing a bit, murmuring among themselves. They have likely been discerning together this very point for a while as they walked or rested, but now? Now, they must uncomfortably declare what they believe in front of Jesus and one another.
And reflecting his bold personality but also his leadership role in the group, Simon blurts out their shared hope. “You are the Messiah, the Son of the living God” (Matthew 16:16). Here, Simon has spoken the ultimate truth about Jesus. He has named the proverbial key to it all…the foundation of our faith that rests in Jesus. And as is not unusual in tribal based societies, Jesus gives Simon a new name to reflect this momentous action or moment. He is renamed Peter which means Rock.
Yet interestingly, Jesus does not give him full credit. Flesh and blood have not revealed this to Peter – not any computations in his mind, or words of another apostle or any human. God the Father has revealed this through God’s Spirit. As Lutheran Christians, we understand that only through God’s work can we identify Jesus as Lord. If you believe that Jesus is Lord, it is the Holy Spirit at work in you. You have been called and chosen no matter how small, weak, and imperfect you feel.
Yet, some Christians still overly focus on our personal decision to believe in Jesus…as if faith is a moment in time, a declaration we must make, or something under our power. So much so, people can forget that it isn’t fully our decision after all. It is good to stand up and declare Jesus our Lord. (Lutherans do so at baptisms, and every time we say the Creed, and even when we become adults in the Church through the rite of Confirmation.) God comes to us first…decides to love us and set us apart. Yes, we might read scripture and learn about Jesus, hear of Jesus from others and be invited to follow, but a lot of people have read scripture or heard of Jesus and not come to believe. Yet, the Spirit alone acts within these actions and circumstances to help reveal to us the divine identity of Jesus to us. This is when the time is right for us and the community around us.
Then, we have the problem of what exactly is the rock that Jesus will build his Church upon. Popes, Patriarchs, pastors and priests, along with self-proclaimed Apostles, Prophets and charlatans, have at times declared they are the arbiters of faith at times. Sometimes this puts Christians at odds as much or even more so then the Pharisees, Sadducees, Priests, Essenes and other sects existing in Jesus’ time.
Yet Christ is our cornerstone, and that statement of faith in Jesus as Messiah, Son of the Living God, proves our shared foundation…nothing else on this earth…no Pope, no denomination, no dogma, no theology, no worship style, no hymnal, not even ourselves. In scripture, the Letter to the Hebrews simply declares, “Faith is the assurance of things hoped for, the conviction of things not seen” (Hebrews 11:1).
If you take the time to review Luther’s writings or even just the ELCA’s website, you will hear that Martin Luther similarly wrote, “Faith is a living, daring confidence in God’s grace,” a grace that comes to us only through the sacrifice, death, resurrection and ascension of Jesus, as the Son of God; pointing us in love toward others and the world. Yes, in trying to follow Jesus, Christians can wrongly claim exclusivity. We are right, and others are wrong. We are saved, and they are not. Yet in doing so, as again Luther cautioned, we risk being unbiblical by serving as divine judge and limiting God’s authority to dispense grace as God wills.[v] This echoes the yeast of the Pharisees: hypocrisy, rigid religiosity, and placing obstacles in the way of faith. No, we are not saved by perfect theology or actions…just grace.
Thankfully since the horrors of World War 2 with Christians murdering Christians and many others, there has been a great effort to work towards oneness; remembering that Jesus prayed that his Church may be one as our Triune God is one (John 1722). Even some Roman Catholic resources understand that “In Matthew 16 and [later] Matthew 18, Jesus gives the disciples authority over binding and loosing,” all of them, not just Peter.[vi] The same authority given to Peter in Matthew 16 is given to all the disciples in Matthew 18. It says “you all” have the power to bind and loose. The Pharisees used that specific term, “binding and loosing,” and Jesus and his first disciples knew what it meant. And that phrase inferred that we are to communally “discern authoritative, doctrinal, and disciplinary decisions.”[vii]
In the end, we who believe in Jesus share the keys to the Kingdom, but Jesus remains Lord of his House. Thus, our declarations regarding faith and life, as well as our ecumenical if not interfaith discussions and disagreements, can prove important. Yet we need to humbly remember that we always can err. Our pronouncements can become a wound to others or distraction from biblical truth. We need to remain humble, not triumphant, continuously reforming in light of the revelation of scripture; repenting as necessary. We are to do so in conversation with one another and the teachings of the historic Church, those that came before us. Yet again, Jesus warns us to proceed with caution, not pride, as did Paul in our letter today. For we and our pronouncements can become a stumbling block to another’s fragile faith through our lack of patience, wrongheaded attitudes, blind arguments, lack of compassion, empathy, or love.[viii] Because that is the yeast of the Pharisees.
Echoing the Lutheran theologian (from the late 1800s to early 1900s), Ernst Troeltsch, we discover that we should not confuse sect with Church. To him, a sect is a small, voluntary, and exclusive group that rejects the secular world and demands intense personal devotion from its members and a conscious, adult conversion. Meanwhile, a healthy Church aims to include all of society, even infants through Baptism. It accepts secular authority, reflecting Luther’s own belief in Two Kingdoms. Imperfect as they can be, god can use them. The Church is a place where grace is mediated through sacraments.[ix] We understand that to be Baptism and the Lord’s Supper. Still, even then, Jesus says that he came to draw all people to himself through his sacrifice (John 12:32). The Spirit might yet widen our definition and understanding of the eternal “Church” in surprising ways beyond our imagination…but that’s God’s judgement.
Most simply, faith remains trust in Jesus as the Son of the Living God. Faith in him ultimately makes us saints despite our sins, and creates one holy, catholic (meaning universal) Church despite our denominational divisions or blindness. Thus, Christ’s Church is not any building, singular polity or religious practice, but a spiritual, imperfect communion of those in the flesh that trust in Jesus as Lord…sinner-saints all…in need of ongoing repentance and grace. I’ve often said to friends, my faith is in God, not my denomination.
Remember, it was Jesus who established and continues to build his Church for our sake. He is here with us when two or three gathers in his name to heal our wounds, to forgive our sin, to move us toward reconciliation, and through God’s Spirit seeks to draw us closer to God’s self and make us more holy…transforming us as Paul says. It is he who called each of us here today…or drew you to watch online…and asks us to love others as we are loved. We can come without fear with open hearts declaring Jesus as our Lord. For our faith is in Jesus, the Son of the Living God, who has come to love and save us. Our faith will be used to connect us to him and one another under his roof, the Church, forever…because he loves us, and he is our God. Amen.

[ii] At least as a whole, this proves true. Some will come to believe in Jesus despite the animosity of the religious groups or classes they belong to.
[iii] See “Mandaeans” on Wikipedia. Numbered from around 60,000 to 100,000 believers today. “They may have been among the earliest religious groups to practice baptism, as well as among the earliest adherents of Gnosticism, a belief system of which they are the last surviving representatives.” Based in Iraq, they have been persecuted and spread out due to the Iraq War.
[iv] See “Menachem Mendel Schneerson” on Wikipedia. “During his lifetime, many of his adherents believed that he was the Messiah, though not all Chabadniks subscribe to this belief. His own attitude to the subject, and whether he proclaimed it, is hotly debated among academics and scholars of Judaism.”
[v] The Augsburg Confession indicates that we wanted to remain in relationship among differences, but as time went on, Lutherans also condemned many, including other Lutherans, sometimes killing or persecuting them. And we were and are condemned in turn by others.
[vi] See for example https://catholicproductions.com/blogs/blog/whatever-you-bind-and-loose. In addition, the Catholic Catechism and Canon Law indicates the Pope only has infallible authority when making rare, dogmatic declaration on faith and morals. As noted by Catholic Answers at https://www.catholic.com/tract/papal-infallibility, infallibility means protection from teaching doctrinal error. It does not mean the pope is free from personal sin or bad decisions. Martin Luther argued that Councils could err along with the pope. Papal infallibility was not claimed until the First Vatican Council (1869-1870).
