16 Sunday Ordinary Time
Jesus teaches through parables because the kingdom of God is a mystery into which we must enter, rather than a problem that can be answered quickly and neatly. The parables of the wheat and weeds, the mustard seed, and the yeast show that God’s kingdom is already present but not yet complete: good and evil still coexist, while God quietly brings growth through small acts of faith and love. Each of us helps build the kingdom whenever we allow Christ’s word to bear fruit in our lives and plant seeds of goodness in the world.

We are living through what many people call an artificial intelligence revolution. Whenever we need information, help with planning, or an answer to a question, we can simply turn to the AI tool of our choice. Within seconds, it gives us something clear, direct, and concise.
Many of us have grown accustomed to answers like that. We want things explained quickly and neatly.
Jesus, however, does not teach like artificial intelligence.
Jesus teaches in parables. His parables draw upon things that he and the people around him would have encountered every day: fields where seeds were planted, weeds growing among wheat, a tiny mustard seed, and yeast mixed into dough.
Yet Jesus’ parables are not always straightforward. Sometimes they are puzzling. Rather than giving us a simple answer, Jesus invites us to wrestle with a mystery. He wants us to enter into the story, reflect upon it, and discover where we fit within it.
In Matthew’s Gospel, Jesus often uses parables to describe the kingdom of God, also called the kingdom of heaven. The kingdom is so central to Jesus’ mission that we cannot really understand what Jesus is doing unless we understand something about it.
For us, the idea of a kingdom may seem old-fashioned. Certainly, we still have King Charles on our money, but most of us do not think of ourselves as living in a kingdom.
In Jesus’ time, however, kingdoms were a familiar reality. The people of Israel longed for the restoration of the kingdom of David—a time when they would live in their own land, in peace and freedom. Over time, they began to hope for a Messiah who would establish God’s kingdom in a definitive way.
This is the kingdom Jesus announces in his parables. It is unlike any earthly kingdom. It is the world as God desires it to be: a kingdom of justice, peace, mercy, and communion with God. It begins here and now, and it reaches its fulfilment in eternal life.
Theologians sometimes describe this mystery by saying that the kingdom of God is already here, but not yet complete.
The kingdom is already here because Jesus has brought salvation. Through his death and resurrection, he has defeated the power of sin and death. Wherever people live according to the Gospel—where there is mercy, forgiveness, justice, and love—the kingdom of God is already present.
At the same time, the kingdom is not yet fully realized. Evil remains in the world. We still experience sickness, suffering, injustice, corruption, and death. We await the return of Christ, when God’s kingdom will be revealed in its fullness and all things will finally be made right.
The parables we hear today help us understand how to live within this tension between the “already” and the “not yet.”
The first question they address is difficult but important: How can there be so much good in the Church and, at the same time, so much sin and failure?
We are all familiar with the failings of the Church. We can look back upon the violence of the Crusades and the Inquisition. In modern times, we have had to confront the terrible reality of clergy sexual abuse. Within the Church, we find great saints, but we also find serious sin. How can both exist together?
Jesus addresses this mystery in the parable of the wheat and the weeds.
Christ sows good seed in the world. As we heard in the parable of the sower, God’s word is planted within us. Yet we remain free. We can allow that word to bear good fruit, or we can resist it.
Through our choices, we can produce wheat: kindness, generosity, faithfulness, patience, and love. But we can also allow weeds to grow: violence, greed, jealousy, selfishness, and division. The enemy works against what Christ is building.
This mixture of wheat and weeds is found in the world, in the Church, and even within our own hearts. Each of us can recognize both good desires and sinful tendencies within ourselves. With the help of God’s grace, we continue trying to cultivate what is good and remove whatever prevents us from bearing fruit.
The parable also warns us against being too quick to judge and condemn others. The servants want to pull up the weeds immediately, but the landowner tells them to wait, because in pulling up the weeds they might also uproot the wheat.
The final judgment belongs to God. Our task is not to decide who is beyond redemption. Our task is to remain faithful, to encourage what is good, to work against evil, and to trust that Christ will finally set all things right.
The second question addressed by these parables is one many of us ask: With so many challenges in my life and so many problems in the world, how can someone as limited as I am make any real difference?
Here, the parable of the mustard seed offers us great encouragement.
The mustard seed begins as something extraordinarily small, but it grows into a large plant in which the birds can find shelter. In the same way, a small act performed with Christ can bear fruit far beyond what we can see.
A kind word, an act of forgiveness, a moment of patience, a prayer offered for another person, or a decision to help someone in need may seem insignificant. Yet God can use these small actions to begin something much larger.
We know how something can “go viral” on social media. A simple picture or short video can be shared again and again until it reaches thousands or even millions of people.
Goodness can also go viral.
One act of compassion can inspire another. One person’s courage can strengthen a whole community. One small seed of faith can grow into something that provides shelter and hope for many others.
We can think of Saint Teresa of Calcutta. She began by serving people who were poor and dying on the streets of one city. Her work seemed small compared with the enormous suffering in the world. Yet that small seed grew. Her witness inspired her religious community and countless others throughout the world to serve people who had been forgotten.
The kingdom also resembles yeast mixed into flour. Yeast is almost invisible, but it gradually works its way through the whole batch of dough. In the same way, God often works quietly. The kingdom does not always arrive through dramatic events. It grows through ordinary people who allow the Gospel to transform their homes, workplaces, parishes, and communities.
Jesus’ parables do not give us the kind of quick and simple answer that an AI program might provide. Instead, they invite us into the mystery of God’s kingdom—a kingdom already present among us, but not yet complete.
Every time we pray the Our Father, we pray for this kingdom:
“Thy kingdom come, thy will be done, on earth as it is in heaven.”
When we pray these words today, let us remember that we are not merely waiting for God’s kingdom to arrive sometime in the future. Through the grace of Christ, it has already begun.
And each of us has the privilege and responsibility of helping it grow—sometimes through great sacrifices, but more often through small seeds of goodness planted faithfully each day.
