# What the Algorithm Cannot Carry Last Tuesday I sat with a man whose marriage was ending and whose faith was going with it. I had my phone in my pocket — the one with the AI assistant that can summarise Barth, draft a sermon outline in thirty seconds, and answer questions about the Greek aorist. I did not reach for it. I'm not sure I could have explained why, in the moment. But I've been trying to explain it ever since. What follows is not a takedown of large language models. I use them. Most pastors I know use them, even the ones who claim they don't. The question is not whether AI belongs in pastoral life but what it cannot do there, and why those incapacities matter more than the things it does brilliantly. ## The Seduction Is Real and We Should Admit It I want to start by being honest. The tools are extraordinary. On a Thursday afternoon, with a Sunday sermon still half-formed and three hospital visits behind me, I have asked ChatGPT to summarise the structure of Hebrews 11, suggest five illustrations for the phrase "assurance of things hoped for," and produce a working translation of a difficult phrase in the LXX. Within minutes I had material that would have taken me an hour to assemble from commentaries. Admin is the same story. Drafting a letter to a difficult congregant; tidying minutes; reformatting a rota; building a reading plan for a small group on the doctrine of providence. These are real hours saved, and the hours saved are real hours given back — to my wife, to my children, to the man whose marriage was ending. I say this because the critique that follows is not the reflex of someone who has never tried the thing. The critique only counts if you have felt the pull. AI is useful in the way that the printing press was useful, in the way that the index card was useful, in the way that the search bar was useful. Pastors who refuse to engage with it on principle will, I suspect, become a slightly grumpier version of pastors who refused to engage with the photocopier in 1985. They will not be more spiritual. They will just be slower. So the question is not whether to use it. The question is what it cannot do. And here, I think, there are at least three things — three incapacities that are not bugs to be patched in the next release but features of the technology that no version will ever overcome, because they belong to a different order of reality altogether. ## Presence Is Not a Feature The first thing AI cannot do is be there. I do not mean this as a sentimental gesture toward "human warmth." I mean it as a theological claim. The Christian faith is built on the staggering fact that God did not save us by remote transmission. He did not send instructions. He sent a Son. "The Word became flesh and dwelt among us" (John 1:14). Every doctrine of incarnation, of sacrament, of resurrection, hangs on the conviction that bodies matter to God — that the deepest realities of grace travel through skin and breath and shared space. Augustine's famous line in the Confessions — "you have made us for yourself, and our heart is restless until it rests in you" — is often quoted as a truism about human longing. But notice what it implies. The restlessness is not solved by acquiring better information about God. It is solved by encounter. By presence. By being known and being held by a Person. The pastor who turns up to the hospital bedside, who sits in the awkward silence after the diagnosis, who hands the bereaved widow a cup of tea she will not drink — that pastor is doing something AI structurally cannot do. He is enacting a small echo of the Word-made-flesh. He is saying, with his body, what the gospel says with its whole architecture: that you are not alone, that God has come close, and that he has sent me to sit with you because he himself sits with you. A chatbot can produce sentences about presence. It cannot be present. The difference is not a matter of degree. It is a matter of kind. I think this is why I did not pull out my phone last Tuesday. Not because the AI would have given bad advice — it might have given perfectly serviceable advice. But because the man across from me did not need advice. He needed a witness. He needed someone whose own breath was in the room with him, whose own face would carry the weight of what he was saying. The algorithm could not carry it. I could, just about, and only because I have been carried myself. ## The Machine Has Never Buried Anyone Which brings me to the second incapacity. Paul writes to the Corinthians about the strange logic of pastoral comfort: "Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, who comforts us in all our affliction, so that we may be able to comfort those who are in any affliction, with the comfort with which we ourselves are comforted by God" (2 Corinthians 1:3–4). Read that sentence carefully. The comfort the pastor gives is not generated. It is transmitted. He gives what he has received. The structure is genealogical. You comfort because you have been comforted. You sit with the grieving because you have grieved. You speak hope into a depression because hope was once spoken into yours. This is the pastoral logic of the New Testament, and it is the precise logic AI cannot reproduce. A language model has read every grief memoir ever written. It has ingested the entire corpus of Christian devotional writing on suffering. It can generate paragraphs of remarkable verbal beauty about loss. But it has never lost anything. It has never sat at 3am with its phone in its hand wondering whether to ring a friend. It has never buried a parent. It has never held a child who would not stop crying because she did not yet have the words to say what was wrong. The pastor's authority to speak into suffering is not the authority of expertise. It is the authority of solidarity. When I tell a young man in my congregation that the dark months will pass, I am not making a prediction based on statistical priors. I am telling him something I know because I have been there, and because the people who held me when I was there are also still here, also still being held. A friend of mine, a hospital chaplain in his sixties, once told me that he never feels less useful than when families thank him for "knowing what to say." He never knows what to say. He just keeps showing up, and the showing up is the thing. "Half my ministry," he said, "is being a body in a chair." A body in a chair. The machine has many gifts. It does not have a body, and it has never sat in a chair. I worry about a pastoral generation that learns to outsource the language of comfort before it has done the work of being comforted itself. The words will sound right. They will be the right words. But they will float, untethered from the wound that gave them weight, and the people who receive them will feel the difference, even if they cannot name it. ## Accountability Requires a Body That Can Be Fired The third incapacity is more institutional, but no less serious. Pastoral authority, in any healthy church polity, is hedged about with accountability. Elders examine the pastor. The congregation can withdraw its confidence. Denominations have disciplinary processes, however imperfect. A pastor who teaches heresy can be removed. A pastor who behaves badly can be confronted. A pastor who is simply failing can be helped, or, in the last resort, let go. This structure is not bureaucratic overhead. It is what makes pastoral authority safe enough to receive. When I sit under the preaching of my own pastor, I am not trusting his personal charisma. I am trusting the structure that surrounds him — the elders who have examined his life, the congregation that has called him, the denomination that has ordained him. If he goes wrong, there are people whose job it is to notice, to confront, to correct. The accountability is what makes the authority bearable. An AI cannot be held accountable. There is no body to discipline. No conscience to appeal to. No history of relationships in which trust has been built or broken. If a chatbot tells a young woman in your church something theologically catastrophic about her sexuality, or her suffering, or her dead grandfather's eternal destiny, what is the recourse? You can complain to OpenAI. You can switch models. You cannot rebuke it. You cannot pray with it. You cannot watch its life over the next five years and see whether it bears the fruit of repentance. This matters more than we have yet grasped. A great deal of pastoral harm in the last fifty years has come from authority unchecked by accountability — celebrity pastors, unaccountable platforms, ministries built around a single voice with no eldership able to say no. The temptation of AI is to scale that pathology to infinity: a voice that speaks with apparent confidence about ultimate matters, available at all hours, answerable to no one, and trusted by people who do not understand the technology well enough to know what it is doing. I am not saying people should not use AI to ask theological questions. They will, whether I approve or not. I am saying that the pastor's job description is not just to give answers but to give answers under accountability — answers that he will have to defend on Sunday, to elders on Tuesday, and to Christ on the last day. That accountability is not a limitation on his ministry. It is the thing that makes his ministry worth receiving. ## What Silicon Valley Gets Wrong About Information Underneath these three incapacities is a deeper category error, and it is worth naming. The implicit theology of the AI industry is that human flourishing is fundamentally an information problem. Give people better access to better information, faster, in a more personalised form, and their lives will get better. It is a hopeful vision. It is also, when applied to the pastoral task, almost entirely wrong. Nietzsche, who was wrong about many things but right about this, mocked the modern scholar as the man who has swallowed an encyclopaedia and digested nothing. He saw the danger of confusing the accumulation of facts with the formation of a soul. "Knowledge," he wrote in one of his more lucid moments, "has in us been transformed into a passion which shrinks at no sacrifice and at bottom fears nothing but its own extinction." He was warning against the idea that knowing more makes you more. The Christian tradition has always known this. Pastoral ministry is not information transfer. It is formation. It is the slow, often invisible work of helping people become the kind of people who can love God and neighbour. You cannot download that. You cannot summarise it. You cannot get a sufficiently advanced model to produce it for you. It happens in shared meals, in long conversations, in the awkward moment when someone says something you disagree with and you have to decide whether to challenge it or let it sit. It happens in the slow accumulation of a thousand small acts of faithfulness over a thousand ordinary weeks. The chatbot can give you the content of the faith in a hundred elegant paraphrases. It cannot form you in the faith, because formation requires a relationship across time with someone who themselves is being formed. Paul did not tell Timothy to consult a library. He told him to follow him as he followed Christ. The pattern is irreducibly personal, irreducibly slow, irreducibly embodied. When pastors confuse their job with information delivery, they make themselves replaceable by tools that deliver information better. When they remember that their job is the formation of a people, they discover that the tools, however clever, are working at a different level of the problem altogether. ## The Congregation as the Thing AI Cannot Replicate I planted a church, with a friend I have known since we were boys, in a part of London where drug dealers live in the same postcode as City economists and neither tends to know the other's name. On a good Sunday, both of them are in the room. So is the elderly Nigerian woman who has been a Christian for sixty years, and the graduate student who is not sure she believes any of it, and the young father who has not slept properly since the baby came, and the recovering addict who is six months clean and terrified of week seven. What holds them together is not a shared demographic, a shared politics, or a shared aesthetic. They cannot agree on Brexit, on the colour of the carpet, or on whether the music is too loud. What holds them together is that they are learning, slowly and with many setbacks, to love each other because Christ has loved them. This is the thing AI cannot replicate, and it is also the thing the pastor is shepherding toward. The end of pastoral work is not a well-informed individual with a strong personal devotional life. The end of pastoral work is a community , a strange, mixed, awkward, beautiful community across class and culture and age and grief and joy , that bears witness to a reconciled humanity because it has been reconciled to God. You cannot get that from a tool. You can only get it from a body, a real body of real people who keep turning up to each other through years of small disagreements and large griefs. The pastor's work is to love these specific, difficult, irreplaceable people, and to help them love each other. That is not a task with an efficiency curve. It is the thing itself. Micah's old line keeps coming back to me: "what does the LORD require of you but to do justice, and to love kindness, and to walk humbly with your God?" (Micah 6:8). Walk. Not stream. Not query. Walk. ## So What Do We Actually Do With It So I do not want to land in a place of anxiety, because anxiety is not a Christian posture toward any tool. Let me say plainly what I think a sensible pastor does with AI now. Hand it the things it does well: exegetical research, language work, illustration hunts, sermon outlines you will heavily rewrite, admin emails, rota spreadsheets, the first draft of the welcome leaflet, the suggested reading list for a topical series. These are good uses. They will save you hours. The hours you save are not gains for the machine; they are gains for the people you serve, if you spend them well. Guard fiercely the things it cannot do. Pastoral visits. The preparation that comes from your own prayer over your own people. The decision, in a counselling session, about whether to speak or be silent. The funeral sermon for someone you actually knew. The slow building of trust with the elder who disagrees with you. The Sunday morning encounter with the visitor who is not sure why they came. The hospital chair. The kitchen table. The walk after church when the teenager wants to ask you something real. And learn the difference. The pastor who knows what to hand to the machine and what to keep for himself will serve his people better than the pastor who refuses to use any of it, and far better than the pastor who quietly outsources his soul to it. The discernment is the discipline. There is no app for the discernment. Last Tuesday, the man whose marriage was ending did not need a summary of Barth on covenant. He needed a friend who would not look away. I am not always that friend, and I have failed people more times than I can count. But on Tuesday I sat there, and we prayed, badly, and after a while he cried, and after a while longer he stopped, and we agreed to meet again on Friday. The algorithm could not carry that hour. It was never going to. The hour was carried by Someone else, working through a very ordinary pastor in a very ordinary room. That is the only ministry I have ever known, and it is the only ministry, I suspect, that has ever been worth anything. "We have this treasure in jars of clay, to show that the surpassing power belongs to God and not to us" (2 Corinthians 4:7).
