Readings
Romans 12.1–8 – I appeal to you therefore, brothers and sisters, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewing of your minds, so that you may discern what is the will of God—what is good and acceptable and perfect. For by the grace given to me I say to everyone among you not to think of yourself more highly than you ought to think, but to think with sober judgement, each according to the measure of faith that God has assigned. For as in one body we have many members, and not all the members have the same function, so we, who are many, are one body in Christ, and individually we are members one of another. We have gifts that differ according to the grace given to us: prophecy, in proportion to faith; ministry, in ministering; the teacher, in teaching; the exhorter, in exhortation; the giver, in generosity; the leader, in diligence; the compassionate, in cheerfulness.
Matthew 16.13–20 – Now when Jesus came into the district of Caesarea Philippi, he asked his disciples, ‘Who do people say that the Son of Man is?’ And they said, ‘Some say John the Baptist, but others Elijah, and still others Jeremiah or one of the prophets.’ He said to them, ‘But who do you say that I am?’ Simon Peter answered, ‘You are the Messiah, the Son of the living God.’ And Jesus answered him, ‘Blessed are you, Simon son of Jonah! For flesh and blood has not revealed this to you, but my Father in heaven. And I tell you, you are Peter, and on this rock I will build my church, and the gates of Hades will not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.’ Then he sternly ordered the disciples not to tell anyone that he was the Messiah.
Sermon
There are some questions where the answer doesn’t matter very much once the moment is passed. “What shall we have for tea?” “Where did I put my keys?” “Who left the lights on?” They may feel urgent at the time, but life carries on whatever the answer. And then there are questions which get right underneath everything. Questions whose answers shape the way we understand ourselves and the way we live. Jesus asks one of those questions in today’s Gospel.
He and the disciples have come to Caesarea Philippi, and he asks them: “Who do people say that the Son of Man is?” It’s an easy enough question to begin with, because it’s about what other people think. And the disciples have clearly been listening. They’ve heard the rumours and the conversations. Some say John the Baptist. Others Elijah. Others Jeremiah, or one of the prophets. Plenty of opinions. Plenty of speculation.
And then Jesus changes the question. “But who do you say that I am?” Suddenly it’s personal. Jesus isn’t asking what the crowds think. He isn’t asking what the religious experts have written. He isn’t even asking the disciples what they were taught as children. Who do you say that I am?
And Peter answers: “You are the Messiah, the Son of the living God.” It is one of the great moments in Matthew’s Gospel. Peter gets it. Or at least, Peter gets it for a moment. Because one of the things I love about Peter is that the Gospels never tidy him up. He can make a magnificent confession of faith one minute and get things spectacularly wrong the next.
In fact, that is exactly what happens here. We stop reading at verse 20 this morning, but if we carried on for only a few more verses, Peter would be rebuking Jesus for talking about suffering and death, and Jesus would say to him, “Get behind me, Satan!”
Quite a turnaround. “You are Peter, and on this rock I will build my church.” And then, moments later: “Get behind me, Satan!” Which is worth remembering whenever we imagine that being a faithful Christian means having everything sorted out. Peter certainly didn’t.
He had faith. He also had doubts. He could be brave and frightened, perceptive and completely mistaken. He promised Jesus that he would never desert him and then denied three times that he even knew him. And yet Jesus says: “On this rock I will build my church.” There is hope for all of us in that.
Because the Church is not built out of perfect people. It never has been. The Church is built out of people who, like Peter, are learning what it means to say, “You are the Messiah, the Son of the living God,” and then trying to work out what that confession means on Monday morning.
And perhaps that is where Paul’s words to the Romans help us. Paul writes: “Present your bodies as a living sacrifice, holy and acceptable to God.” In other words, faith cannot remain simply an answer to a question.
Peter says who Jesus is. Paul asks what happens next.
If Jesus really is the Christ, then that changes something. Not simply what we believe in our heads, but how we live. How we spend our time. How we use what we have. How we treat people. What we do with the gifts God has given us.
“Do not be conformed to this world,” Paul says, “but be transformed by the renewing of your minds.”
That transformation is not about becoming some impossibly holy version of ourselves. It is about allowing our encounter with Christ gradually to reshape us. And Paul immediately makes that very practical. We have different gifts, he says. Prophecy. Ministry. Teaching. Encouragement. Giving. Leadership. Compassion. Not everyone does everything.
That matters enormously for the life of the Church. Sometimes we can slip into thinking that there are a few people who “do ministry” while everybody else comes along to receive it. But that isn’t Paul’s picture of the Church at all. For Paul, the Church is a body. Different people, different gifts, different callings — but each one belonging to the others.
And that takes us back to Peter. “On this rock I will build my church.” Notice whose Church it is. Not Peter’s. Not the disciples’. Not the clergy’s. Not ours. Christ says, “I will build my church.” That can be both challenging and wonderfully liberating.
Because we can become terribly anxious about the Church. We worry about congregations and buildings and money and volunteers. We worry about whether younger generations will come. We worry about what things might look like in five or ten or twenty years. Some of those concerns are perfectly reasonable. We have responsibilities and we should take them seriously.
But the future of the Church does not ultimately rest upon our ability to keep everything going. “I will build my church,” says Jesus. Our task is not to save the Church. Our task is to be the Church. To worship Christ. To love our neighbours. To serve our communities. To recognise and use the gifts God has given us. To welcome people. To forgive one another. To speak of hope. To notice those whom everybody else overlooks.
And, through all of that, to keep answering Jesus’ question: “Who do you say that I am?”
Because that question never really goes away. We may have recited the Creed hundreds of times. We may have worshipped in church for decades. We may know the stories and the hymns and the prayers by heart. But Jesus still asks: Who do you say that I am?
Not simply with your lips. With your life. Who do you say that I am in the way you treat the difficult neighbour? Who do you say that I am in the way you use your money? Who do you say that I am when somebody needs your time? Who do you say that I am when you are frightened about the future? Who do you say that I am when faith feels uncertain and prayer feels difficult?
Peter’s answer was not the end of his journey. In many ways, it was only the beginning. He still had an enormous amount to learn about what kind of Messiah Jesus would be. He would fail. He would misunderstand. He would run away.
But Christ did not give up on him. And Christ built his Church with people like him. People like us. Ordinary, complicated, gifted, fallible people who have heard Christ’s question and, however imperfectly, have found themselves saying: “You are the Messiah, the Son of the living God.”
And if it is his Church, then perhaps we can hold it a little less anxiously and serve it a little more joyfully. Because the foundation of the Church is not our competence, our strength or even the certainty of our faith. The foundation is Christ himself. The Messiah. The Son of the living God.
And the one who is still building his Church through wonderfully imperfect people like us.
Amen.
