Do No Harm Timothy Carson
Matthew 13:24-30 July 19, 2026
I have struggled with this parable of Jesus. It’s quite beautiful, but it provokes and raises more questions than it answers. Was it told with the background of many Jewish sects in mind? Were the disciples surrounded by competing voices, some of them hurtful or even misleading? Was there dissention in the ranks? Whatever historical context gave rise to this parable, its universality allows it to still provoke us today. The story goes this way:
Once upon a time a farmer sowed good seeds in the field. So far so good. But one night a vandal or antagonist sowed weeds in that field of wheat. When the wheat grew up and sprouted the weeds were right alongside it. And the servants were agitated: What happened? Where did these weeds come from?! You can feel how irate they were. The farmer answers, Who knows, a prankster, somebody trying to ruin me?
Then the servants said, Should we go weeding? And here is the crux of the parable. The farmer answers, No, because pulling the weeds could harm the wheat. Just let them grow together until harvest and we’ll sort out the wheat from the weeds then.
Well that’s not satisfying. It runs against our grain:
Let’s get out there and do something, take care of the problem, nip it in the bud, so to speak. Above all, we want to fix the problem. But as we all know, trying to fix the problem often makes it worse.
One time we were living in St. Louis and a water pipe in the basement was leaking. I used some of that instant plummer to stop the leak but that didn’t work. So I thought I would just take a wrench and tighten it … until one twist too far and the whole pipe came free and water was going everywhere and I was drenched.
Sometimes trying to fix it makes it worse, especially if we don’t know what we’re doing. That recalls the most basic principles of ethics from Aristotle to the Hypocritic oath: Do good and Do no harm.
Sometimes the attempt to do good creates more harm so one has to use caution. And that is at least one thing at work in Jesus’ parable. The council of the farmer is to not harm the wheat by trying to eradicate the weeds. Just let them grow together.
One time my father-in-law was living with us, and he was determined to take care of the weeds growing along a fence line. He got out the Round Up and gave it a good application. That did it, alright. The weeds were dead and gone. But the same day he applied it the wind was blowing and he inadvertently sprayed the whole side yard. In short order the yard was brown as brown can be. Sometimes killing the weeds kills everything else.
No, Jesus said in his parable, error on the side of doing no harm.
But what if we are faced with a clear case of injustice, even genocide? What if those weeds are a malignant evil that’s harming people? Do we just stand by and let it happen?
I recently retraced some of the steps of the German pastor and martyr, Dietrich Bonhoeffer, who died resisting the fascism of the Nazis in WWII. He was the original Antifa, just like all those troops landing on the beaches of Normandy were Antifa – antifascists.
As a Lutheran pastor and theologian, Bonhoeffer struggled with what was the right moral response to Nazism. He ultimately concluded that one can’t sit it out when the tyranny and violation is in front of you. You have to decide. You can’t be neutral. You have to act.
Just how does this jibe with Jesus’ parable? Don’t pull up the weeds because you might hurt the wheat? Just let it grow and in God’s good time it will be sorted out? How much time? At what cost?
Bonhoeffer decided that he had no moral choice but to resist the evil of the Nazis, even as millions of German Christians stood by and did nothing.
We share Bonhoeffer’s moral predicament. When and how do we resist injustice committed by the powerful? Is it enough to just count on the goodness of the righteous? Don’t we have to address the greed of the oligarchs who take from the poor and give more to the rich? Don’t we have to stop the Epstein sex trafficking ring and hold them all accountable? Aren’t we obligated to speak against and stop those who harm others for the sake of their own ideology or religion? Don’t we denounce those who pollute our land, water and air so they can profit? Don’t we say, No way, no how to those who would discriminate because of race or gender or orientation? Most of us would say, No, we’re not willing to sit this out. We’re pulling out the weeds before they take over.
Was Jesus’ parable actually sounding an alarm about extremism, what can happen when people go on crusades, intent to pull out every weed at any cost?
You don’t have to go far into purity culture before you find yourselves in a front-row seat at a Middle Ages-like Crusade, vanquishing the foe, converting at sword point, conducting inquisitions to rip out heretics from our midst and staging witch trials to eliminate every element we have defined as unholy. Can we possibly add up all the harm over the centuries that has been committed by the self-righteous in their weeding campaigns?
I think the case can easily be made that Project 2025 of the Heritage Foundation, a blueprint followed by Christian Nationalists in power right now, is doing exactly this. And it doesn’t matter to them how many people they hurt.
I recently listened to an interview with a woman in Austin, Texas as she described what happened when a cherished pregnancy turned terribly bad. There was no hope of saving the fetus and it was putting her life in jeopardy. But she couldn’t get any care because no doctor would provide a medical abortion. Doctors can lose their licenses, or worse be imprisoned under present law. She almost died and she lost all ability to bear future children. All because a radical religious political fringe is intent on pulling out every ideological weed, even at the expense of women’s health.
The parable speaks truth. Do no harm, especially harm generated by self-righteousness crusades, rigid moral systems imposed on others. Don’t pull up the weeds and harm the wheat.
Think of recent administration attempts to root out any vestiges of diversity, equity and inclusion (things they see as bad for white males). They used high powered AI models to scour the websites and grant applications of government agencies, universities and research institutions and withheld authorized grant monies for medical research until they removed all the perceived weeds of DEI. Medical research. They did harm in the name of doing good.
This is a 21st century version of the Inquisition. Whenever we take it upon ourselves to assume the role of god, when we engage in self-idolatry, things turn demonic very quickly.
We need to be just as careful about doing no harm as doing good.
Like most good parables, Jesus casts us into the horns of a dilemma: In the tension between doing good and doing no harm, what and how will we decide? None of our choices will be perfect ones. As Bonhoeffer discovered, we try to do more good than harm, knowing that the good is not perfect and the harm is unavoidable by degree. Do we violate one of God’s laws to be faithful to another?
Your aunt comes in wearing her new dress. She is so proud of it. But it is the loudest, ugliest, most painful thing you’ve ever seen. You love your aunt. What do you say? Are you honest or kind? You could say, “That’s the ugliest thing I’ve ever seen.” Or you could say, “You are as pretty as a picture in that dress.” Which is it? Honesty or kindness? Which wins? The late theologian Tex Sample called this making a tragic choice. Whatever you choose, you’re going to be a little wrong and a little right. How do we balance doing good and doing no harm? That’s going to depend on a lot of grace.
But because a parable is like a diamond with many facets, let’s turn over the gem stone and take a look from a different angle.
There is a particular plant called darnel, and it is a mimic plant; it resembles grains like wheat and oats and grows among them. It was well-known in antiquity. This imposter, this poser plant was the evil twin of wheat. It evolved in such a way that it depended on humans cultivating grain fields so it could survive. And it was toxic. Small amounts could create a mild intoxicating experience, which is why some cultures used it in the fermentation process. But too much and it could make you really sick.
So we have this imposter growing among the wheat, this intoxicating double, and it’s hard to tell the wheat from the weed. At a deep symbolic level this poses interesting questions for us.
Perhaps Jesus was describing the world of illusion we all inhabit. When It’s hard to discern what is what and every field hosts a little masquerade party, we need to be careful how we employ our sickles. In a world of illusion in which darnel resembles wheat and our judgement is far from perfect, we can inadvertently do harm. As Batman says in The Dark Knight, “You either die a hero, or you live long enough to see yourself become the villain.”
Or maybe the darnel that shows up in the field of our consciousness is the necessary trickster who tests us, confounds us, forces us to see things differently. Maybe the field is our psyche, and we must sort out what’s real and what’s not. Maybe the weeds in our lives have an important part to play.
When we cast our glance into the rear-view mirror of our lives, we are sometimes able to see this more clearly. There are some people, some events, some struggles, some inconveniences, some failures, and some losses that bring everything into focus, into clarity, and they challenge the false notions of ourselves or the world that we carry. They are unbidden and unwanted, and we often do not know that we needed them until later.
Like the servants in the story, we find ourselves preoccupied with how to get rid of them. But as a great mystery, the farmer tells the servants not to uproot the weeds, but rather allow them to grow together. Because, who really knows what needs to go and what needs to stay. And maybe we won’t know until much later, not even until harvest.
