A sermon preached at Berkswell church, Sunday 30th August 2026
Thirteenth Sunday after Trinity. Year A
Jeremiah 15: 15 -21
Romans 12: 9 ā end
Matthew 16: 21 ā end
Get behind me Satan. You have set your mind on human things and not the things of God.
Let your love be genuine
One canāt help but feel a little sympathy for Peter. One minute Jesus is giving him the Keys to the Gates of Heaven itself, the next he is dismissed as the very embodiment all that is sinful. First he is given full authority in Heaven and on earth, to loose and to bind, to absolve sin and to impose penance, and then he himself is firmly put in his place, as the most sinning of sinners. One minute he is Peter the Rock, the human foundation upon which Jesus builds his church, and the next he is a different kind of stone altogether, one you trip over, a stumbling block, a hindrance that causes nothing but damage and disaster.
We are at Caesarea Philippi, in hill country to the north of the Sea of Galilee, on the slopes of Mount Hermon, in the Golan Heights, the border land between the modern states of Israel and Syria. At this spot, the fisherman then called Simon has openly recognised that Jesus is the Messiah, the Son of the Living God. He is blessed by Jesus, given a new name in Peter and a new identity as the Rock. He is granted the Keys to Heaven itself and invested with spiritual authority. That was our Gospel reading last Sunday. And no sooner does Peter offer his wholehearted support in the event of Jesus being ill-treated by the civil or religious authorities, than he is cursed and humiliated, rebuked for setting his mind on human concerns and not the things of heaven.
What should he have said or done instead? How should Peter have set aside human concerns and thought only of the divine? How could any of us? Does it mean simply that we should withdraw from human affairs, from political involvement, into a quiet form of contemplative spiritual life, a life in which we rise above the troubles of everyday life both great and small, local, national and international, and seek to live a life of quiet prayer? There are many Christians, very many, who have done this, and who still do. It is a good way of life.
But not the only way. Straight after this shocking castigation Jesus says that we are to take up the cross. And to take up the cross is to become no less than the body of Christ. It was the frail all-too-human body of Jesus, God-made-human, that before us carried that cross. The cross of Crucifixion, the cross of humiliation and ignominy, as well as of agony and of an excruciating death, was carried by Jesus, God-made-Man, carried literally on his all-too-human, frail, vulnerable body, publicly, through the streets of Jerusalem. When Jesus calls us to take up the cross he calls us to be his frail vulnerable, cross-carrying body, publicly in our streets today.
Just as Jesus was himself God in the very particular there and then of Galilee and Judaea of the early first century, Jesus asks us to be his cross-carrying body in the very particular here and now of Berkswell, Warwickshire, England, in the 2020s. To call ourselves the Body of Christ includes recognising two things: that we are to do the work of God in this place and at this time, and that we do so carrying the weight of the knowledge of our own frailty, our own vulnerability, our own weakness and fragility, both individually and even together as one body. To take up the cross and follow, to become the Body of Christ, is to show that human frailty to the powers of the world, a glorious frailty that shames brute force and domination. To take up the cross and to follow, to be the Body of Christ, to set our minds on heavenly things, does not mean withdrawing from the world, but rather it is to be in the world without acceding to the brute power of the world and without conforming to its false values. To be present, but different, and by being present and different to transform and convert, transform and convert others, yes, and to begin that process by transforming and converting our own selves. Paul tells it plainly in our second reading: To bless those who curse us, bless and not curse, to refrain from repaying evil with evil, never to avenge, but to refrain and withhold, to feed our enemies and give them something to drink, and to overcome evil, not with more evil but instead with goodness. Paul sums it up in the opening phrase of our reading: Let your love be genuine.
This is what conforming our minds to the mind of Christ himself means. This is what it is to set our minds not on human things but instead on things divine. Our Salvation includes the transformation of our minds and our hearts as preparation for our full participation in the Kingdom of Godās love. We are partners with God in the serious work of the conversion of our thinking, of the transformation of our minds, as well as our hearts, so that our minds do become set not on things human, but rather on things divine.
From earliest days the teachers of the church understood this. We are, they affirmed, made in the image of God and we are being formed by God after his own likeness, a formation that continues all through our lives, until death and if necessary, beyond death, such is Godās unconditional love for us. Being made in the image of God we already possess, frail and vulnerable though we be, the capacity and desire for virtue, the capacity and desire for right and proper thinking, the capacity and desire to set our minds on the things of God. This is what being in the image of God means: having the capacity and desire for goodness. It is likewise axiomatic that we are still incomplete, still all sinners, that we all fall short, that we all set our minds on the wrong things. Each and every one of us. But being sinners does not mean that we are inherently bad. Quite the opposite. None of us is beyond redemption, as Mark explained powerfully last week, because all of us, each of us, is made in the image of God with the capacity and desire for virtue. Sin is not a character flaw, but rather a mistake in our judgement.
Now, I do not wish to to dismiss our sin as trivial and insignificant. It isnāt, it is a serious matter, a very serious matter. But it is rooted not in the design of human nature, but in a mistake that we make in our application, a mistake in our understanding, our thinking.
Those first great teachers of Christianity, knew this. Humans, they taught, do choose goodness. Sin lies in the mistake of choosing, the wrong goodness, choosing a lesser good instead of a greater good, in mistaking something that is partially good for something more fully good, never mind for that which is the best. Sin is rooted not in a lack of desire for goodness, rather sin is a mistake in our understanding of what goodness is. Like children we seek easy and transient pleasure, mistaking it for something that which is truly good and lasting. Sin is not a character flaw, but rather a mistake.
The ultimate good, that which we ought to prefer above all else is the Love that is God, the love of God and the love of our neighbours, each of whom, like us, is in the image of the God who is Love.
In our pride we mistake our own uniqueness for superiority, thinking ourselves better than our neighbours. In our envy we resent the happiness of our neighbours, thinking their happiness excludes ours. In our wrath we misdirect our anger, blaming others rather than examining our selves and our own actions and responsibility. In each of these we choose the lesser good of love for ourselves over the higher good of love for our neighbour. In our avarice we seek to find happiness in things rather than with people. In our gluttony we seek satisfaction in looking after ourselves rather than seeing to the needs of others. In our lust we separate s*x from the love of another person, use the person as a means and treat the s*x as an end in itself and not as an expression of love. In each of these, we choose the lesser good of our own satisfaction over the higher good of loving our neighbour. In the indifference of our sloth, we simply fail to choose goodness at all. This is thinking the way that men think, and not in the manner of God
Peter is emblematic of us all. Like Peter, we sin, not because we are wicked by nature, but because we mistake a lesser good for the greater good, the greatest good, that is the Love that itself is God. After this shocking rebuke, Peter continued to sin, most prominently in his three-fold denial on the night Jesus was betrayed. Like Peter, we too will continue to sin. Peter was redeemed and blessed after the Resurrection. Like Peter we shall be redeemed and we shall be blessed in the Resurrection. At Caesarea Philippi Jesus castigated Peter for his sin ā but before that he had already chosen him and blessed him. Like Peter, though we sin and set our minds on human desires, though we too deserve castigation, we have already, all of us, been chosen, and already, all of us been blessed.
