“Plagiarism is sin.”
The statement sounds obvious enough. Christians believe stealing is sin. Christians believe lying is sin. Plagiarism, we are told, is stealing someone else’s words or ideas and representing them as our own. Therefore, plagiarism is sin. But that simple syllogism conceals most of the difficult questions.
What, exactly, has been stolen when a preacher uses another preacher’s outline? What lie has been told when he repeats an illustration he heard years ago? What if he adopts an especially effective explanation from a commentary, or structures his sermon according to a sermon commentary specifically written to help pastors preach the text? How many matching words turn ordinary borrowing into a moral offense?
There are unquestionably dishonest ways for pastors to use other people’s work. A man who secretly purchases complete sermons each week, barely studies the biblical text, and represents those sermons as the fruit of his own pastoral labor may be deceiving the congregation that pays him to study, preach, and teach. A pastor can steal intellectual property, lie about authorship, or simply become lazy and neglect the duties of his office. Scripture gives us perfectly adequate categories for condemning such behavior: theft, deception, laziness, breach of trust, and failure to fulfill one’s responsibilities.
But that is precisely the point. “Plagiarism” is not a self-defining biblical category, and modern academic standards of attribution cannot simply be imported into the pulpit and declared the moral law of God. Nor should plagiarism be confused with copyright infringement: the former concerns attribution and representation, while the latter concerns legally protected rights in expression;1 conduct may constitute one without constituting the other.
Is Plagiarism a Biblical Category?
Scripture nowhere establishes a doctrine of intellectual attribution resembling a modern university-style manual. That does not mean Christians should be indifferent to authorship or that anything short of copyright infringement is morally permissible. It means that before declaring a particular instance of borrowing sinful, we should be able to identify the sin.
If a pastor says, “I developed this illustration myself,” when he knowingly copied it from another preacher, he has lied. If he signs his name to another man’s article and claims authorship, he has deceived. If his church pays him to devote substantial time to sermon preparation while he secretly purchases complete sermons and neglects that responsibility, he may be defrauding his congregation. Those are recognizable moral categories.
But suppose a pastor consults six commentaries and incorporates their observations on his exposition without identifying each commentator from the pulpit. Suppose he hears another preacher explain justification with unusual clarity and later uses substantially the same explanation. Suppose a sermon commentary proposes three divisions of a passage, and the pastor concludes that they accurately reflect the structure of the passage and uses them on Sunday morning.
Calling these things “plagiarism” does not settle their morality. It assumes the very standard it needs to demonstrate. There may be circumstances in which attribution is morally necessary, circumstances in which it is professionally required, circumstances in which it is proper, and circumstances in which it would merely distract from communication. Those categories should not be collapsed into one another. The fundamental question is therefore not simply, “Did this preacher use someone else’s words?” It is, “What representation did he make by using them?”
The strongest response is that attribution is simply a matter of honesty: unless a preacher identifies his source, listeners naturally assume that the words, structure, and ideas originated with him.2 But that argument itself depends upon an assumption. Do congregations actually understand every unattributed theological formulation, illustration, or sermonic structure as a claim of personal authorship? Surely not. Christians routinely hear pastors communicate interpretations, doctrinal formulations, illustrations, and arguments accumulated through years of reading and listening without imagining that each originated with the man speaking. In some circumstances, silence about a source can certainly create a false impression. But whether it does so is a question of context and reasonable expectation—not something established merely by demonstrating literary dependence.
The Academy Has Different Rules for a Reason
Academic institutions uphold unusually rigorous plagiarism standards for good reasons. Academic institutions themselves explain these standards in terms of the distinctive purposes of academic work. Purdue, for example, reminds students that they are there to “learn and produce original work,”3 while Harvard requires transparent acknowledgment of others’ contributions to a student’s ideas, interpretations, and conclusions.4 In that setting, intellectual provenance is part of what is being evaluated.
When a professor assigns a research paper, the student isn’t merely being asked to communicate true information. The assignment is also designed to demonstrate whether that student understands the material, can evaluate evidence, and can construct an argument. The professor therefore needs to know which intellectual work belongs to the student and which came from someone else. The same principle applies to scholarship. Citations establish intellectual provenance, permit verification, situate an argument within previous scholarship, and distinguish inherited material from an author’s original contribution.
Under those circumstances, attribution is integral to the task itself. A student can therefore plagiarize a paper containing nothing but perfectly true information. The problem is that he represented another person’s intellectual labor as satisfying an assignment intended to evaluate his own. A sermon has a different purpose.
The congregation does not assemble on Sunday morning to determine whether its pastor can produce doctrinal insights nobody has previously considered. In fact, unprecedented theological originality from the pulpit is usually a reason for concern. The preacher stands downstream from two thousand years of Christian reflection. He consults commentaries, lexicons, systematic theologies, sermons, confessions, articles, and other teachers. He inherits theological terminology, arguments, interpretations, illustrations, and countless turns of phrase from Christians who came before him.
This is not an unfortunate contamination of otherwise original thought. It is one of the ordinary ways Christians learn. The preacher’s task is not to make Christianity novel. It is to preach the truth.
Pastoral Ministry Is an Exercise in Discernment
The pastoral office is therefore better understood as an office of stewardship and discernment than one of original content production. Paul charges Timothy to “preach the word” and to rightly handle “the word of truth” (2 Tim. 4:2; 2 Tim. 2:15). Titus is instructed to hold firmly to the trustworthy word so that he can teach sound doctrine and rebuke those who contradict it (Titus 1:9). The controlling concern is fidelity to truth already given. A pastor is consequently surrounded by other teachers. Their books line his shelves. Their commentaries sit open on his desk. He remembers their sermons and encounters their arguments in articles and conversations. His responsibility is not to pretend these influences do not exist. His responsibility is to judge them.
Is this interpretation faithful to the text? Is this theological formulation sound? Is this illustration helpful? Does this application actually follow from Scripture? Is this something these particular people need to hear?
Consider an ordinary pastoral conversation. A church member approaches his pastor with a deep and difficult question. The pastor talks with him for twenty minutes and then walks to his bookshelf. “You need to read this,” he says, handing him a book. Has he abdicated his responsibility to teach? Of course not. He may know that the author has treated the question more carefully and comprehensively than he could in a brief conversation. Knowing that the book is trustworthy, knowing that it answers this person’s need, and placing it into his hands is itself an exercise of pastoral discernment.
Pastoral teaching is not synonymous with original composition.
The same principle applies to preaching. An illustration borrowed from a faithful expositor does not become useful because the preacher announces its provenance, nor does it become useless because he simply tells it. Conversely, a pastor can meticulously attribute a bad theological argument and still harm his congregation. A preacher can meticulously attribute error and remain an unfaithful preacher; he can borrow truth and faithfully feed the sheep.
This does not mean attribution never matters. Sometimes honesty requires it, courtesy commends it, or identifying a source helps listeners pursue further study. It means that attribution is subordinate to the preacher’s primary responsibility to discern and faithfully communicate truth.
Churches already understand this principle perfectly well in music ministry. Nobody expects the worship pastor to write the songs sung on Sunday morning. He may lead five songs while having written none of their lyrics, melodies, chord progressions, or theological formulations. In one sense, he is using other people’s work wholesale. Nobody accuses him of plagiarism. Why? Because original composition is not the principal responsibility for which the church called him. We expect him instead to exercise discernment: to select songs that are doctrinally sound, pastorally appropriate, congregationally singable, and useful to the particular church he serves.
A gifted worship pastor might never write an enduring congregational song. His faithfulness may be demonstrated precisely by his ability to recognize excellent material written by others and place it into the mouths of his congregation. His dependence upon other people’s work does not diminish the importance of ministerial competence. It makes discernment more important.
And the analogy contains its own limiting principle. We would rightly criticize a worship pastor who indiscriminately imports whatever songs are popular without reviewing their theology or considering his congregation. His failure would not be that he neglected to compose original songs. His failure would be his neglect to exercise the judgment entrusted to him. So too with the preacher.
A pastor who discovers that another expositor has divided a passage according to its natural structure earns no points for inventing an inferior outline merely to establish his originality. Nor does he necessarily serve his congregation by awkwardly rephrasing an unusually clear theological formulation so that the resulting sentence can more confidently be called his own. The pastoral office cannot be reduced to content production. The church does not primarily need a man capable of generating novel words. It needs a man who knows the Word, knows the sheep, and can faithfully discern what the sheep need to hear.
That distinction becomes especially important when we consider the enormous range of practices now gathered under the single accusation of “sermon plagiarism.” Borrowing an illustration, adopting an outline, reproducing several paragraphs, purchasing a complete sermon, and outsourcing sermon preparation to artificial intelligence may all involve someone else’s intellectual labor. But they are not morally identical acts—and textual originality by itself tells us remarkably little about whether a pastor has actually fulfilled his calling.
Not All Borrowing Is the Same
One problem with the term “sermon plagiarism” is that it can obscure the enormous differences among the practices it describes. A preacher might borrow a memorable phrase. He might retell an illustration. He might adopt another expositor’s outline, incorporate an exegetical insight from a commentary, closely paraphrase several paragraphs, or reproduce an extended section nearly word-for-word. At the far end of the spectrum, he might purchase or download a complete sermon manuscript and preach it essentially unchanged. These practices cannot simply be placed into the same moral category because they share the characteristic of dependence upon another person’s work.
Consider sermon outlines. Two faithful expositors working through the same passage should sometimes arrive at remarkably similar structures for the simple reason that the structure is already present in the text. Even when one preacher clearly adopts another’s outline, the question remains: Does the outline accurately organize the passage? Does the preacher understand it? Has he worked through the text himself? Can he explain and defend what he is preaching?
The same is true of illustrations and theological formulations. Preachers accumulate them over decades of reading and listening, often long after their original provenance has disappeared from memory. Some formulations become so common within theological traditions that attempting to establish their original author would be nearly impossible.
Sermon commentaries make the problem even clearer. These resources are written and marketed precisely to help preachers construct sermons. They offer outlines, applications, illustrations, transitions, and homiletical suggestions for the express purpose of being incorporated into preaching. It would be strange to argue that pastors may purchase such material for use in sermon preparation but incur a moral obligation to provide something resembling scholarly citation every time they actually use it. None of this means quantity is irrelevant.
There is an obvious difference between borrowing an outline and standing in the pulpit reading another man’s 4,000-word sermon manuscript. But the difference is not best explained by discovering the precise number of matching words at which borrowing mysteriously becomes sinful. The more important questions concern labor, representation, and pastoral responsibility.
Suppose a pastor purchases a complete sermon every Saturday night, reads through it once, and delivers it Sunday morning with minor alterations. His congregation reasonably believes that its pastor studies Scripture during the week, wrestles with the text, considers their spiritual condition, and prepares to bring God’s Word to bear upon them. Instead, he has effectively hired an invisible substitute. Something serious has happened there. But saying that the sermon contains “plagiarized words” barely begins to describe the problem. The deeper problem may be that the pastor has abdicated the pastoral labor entrusted to him while maintaining the appearance that he is performing it. That is a much more substantial accusation, and unlike an arbitrary similarity percentage, it can be evaluated biblically.
The distinction also explains why circumstances matter. Imagine a bivocational pastor whose church knows that he relies heavily on published sermon materials because he works fifty hours a week and has limited preparation time. The church may knowingly and gladly accept that arrangement. Another church may call a full-time teaching pastor precisely because it expects him to devote twenty hours each week to original exegetical preparation. The identical sermon manuscript could raise very different questions in those two congregations because they involve very different representations and expectations.
Nor is extensive dependence necessarily equivalent to pastoral abdication. A pastor might begin with another preacher’s sermon, verify every exegetical claim, discard applications inappropriate to his congregation, substantially adapt the material, supplement it from commentaries, and spend hours thinking about how this particular text bears upon these particular people. The finished sermon might keep considerable verbal and structural dependence upon its source while nevertheless representing genuine pastoral labor. Conversely, a pastor can produce completely original prose while doing almost no meaningful pastoral or exegetical work at all. That possibility should make us cautious about treating textual similarity as a proxy for ministerial faithfulness.
The real question is not whether someone else’s labor appears in the sermon. Of course it does. The question is whether the preacher has performed the labor that belongs specifically to him: understanding the text, evaluating what others have said about it, rejecting error, selecting what is useful, applying the Word to his congregation, and standing behind what he preaches as true.
A preacher should therefore be able to own his sermon in a deeper sense than literary authorship. He should comprehend its arguments. He should believe its conclusions. He should be able to defend its exegesis. He should have exercised judgment about its applications. If challenged after the service, he should not discover that he has no idea why “his” sermon made the claims it did. That is why purchasing another man’s sermon and functioning as a human text-to-speech device is so troubling. The problem is not simply that the words belong to somebody else. The problem is that the pastoral judgment behind them may belong to somebody else as well.
This also preserves an important distinction between borrowing and deception. If a pastor explicitly tells his congregation, “I came across a sermon this week that handled this passage so well that I want to bring much of it to you,” virtually every accusation of dishonesty disappears immediately, even though the amount of borrowed material remains exactly the same. The words did not become morally permissible when the source was named. What changed was the representation being made. Attribution can therefore matter greatly without becoming the ultimate measure of faithfulness.
The pastor who regularly passes off purchased sermons as the product of substantial preparation may have a serious integrity problem. The pastor who occasionally uses another preacher’s outline, language, illustrations, or even substantial portions of a sermon does not thereby belong in the same category. “Borrowed” is a description of provenance. It is not yet a moral verdict.
To reach the moral question, we must ask what the pastor was expected to do, what work he actually performed, what he represented to his congregation, and whether he faithfully exercised the discernment his office requires. And increasingly, even those questions cannot be answered by looking for another human writer whose words appear in the sermon. A preacher can now outsource almost the entire process of sermon composition and emerge with thousands of words that no plagiarism detector will ever flag.
Artificial Intelligence and the Failure of the Originality Test
Generative artificial intelligence makes the inadequacy of originality as a measure of pastoral faithfulness impossible to ignore. Imagine two pastors preparing to preach Romans 8. The first spends hours studying the passage, consults several commentaries, listens to another preacher’s treatment of the passage, adopts that preacher’s unusually effective outline, and incorporates several of his phrases and illustrations. A comparison of the two sermons might show enough similarities to generate an accusation of plagiarism.
The second pastor opens ChatGPT and types, “Write me a thirty-five-minute expository sermon on Romans 8:28–30 with three points, illustrations, applications, and a moving conclusion.” He lightly edits the result and preaches it Sunday morning. His sermon may contain thousands of words of apparently original prose and never trigger a plagiarism detector. Yet which man has more faithfully performed the work of a preacher?
This is no longer simply hypothetical. Pastors are already experimenting with—and sometimes outright outsourcing—sermon preparation to generative AI. The legal profession has encountered the same problem in spectacular fashion, with attorneys submitting AI-generated filings containing nonexistent cases, fabricated quotations, and other errors they failed to discover because they had outsourced work without adequately verifying it.
In Mata v. Avianca,5 attorneys were sanctioned after submitting fictitious judicial opinions and quotations generated by ChatGPT. Significantly, the court did not suggest that lawyers must personally originate all their research or arguments; lawyers routinely depend upon associates, law students, contract attorneys, legal databases, and other resources. What they cannot outsource is their gatekeeping responsibility to verify what they submit. The preacher occupies a similar gatekeeping role: his study may contain thousands of other men’s words, but he remains responsible for judging what passes from those resources into his pulpit.
The pastor receives no bonus points for discovering an interpretation nobody has previously considered. He is handling an authoritative text within a community that has been interpreting, defending, and applying it for centuries. His responsibility is accuracy, sound judgment, and faithful application—not novelty. Artificial intelligence, therefore, creates a revealing paradox: a sermon can be textually derivative yet pastorally authentic, while another can be textually original yet pastorally fraudulent.
This does not mean AI has no legitimate place in sermon preparation. A pastor might use it to brainstorm questions, test whether an explanation is clear, identify possible objections, or suggest organizational alternatives, just as he uses search engines, Bible software, sermon databases, and commentaries. The relevant question remains whether the tool assists his pastoral judgment or replaces it. And this returns us to pastoral particularity.
A pastor is not simply a delivery mechanism for theological information. He is charged with preaching this text to these people. He knows the widow who buried her husband last month, the teenager wrestling with unbelief, the new Christian struggling to understand justification, and the mature saint who needs exhortation rather than another theological abstraction. Neither a purchased sermon written for another congregation nor an AI-generated sermon written for no congregation at all possesses that knowledge. The pastor does.
That is why the most serious problem with outsourcing a sermon may have little to do with plagiarism. The church did not call its pastor merely because it needed someone capable of producing 4,000 words by Sunday morning. A computer can now do that in seconds. Rather, the church called a shepherd. And shepherding requires something no originality score can measure: knowing the Word, knowing the sheep, discerning what they need, and faithfully bringing the two together.
The Church Gets to Decide What It Expects
None of this requires churches to be indifferent about how their pastors prepare sermons. Quite the opposite. Within the boundaries established by Scripture, a local church has every right to establish meaningful expectations for the men it calls to preach. It may expect its pastor to devote substantial time each week to personal exegesis. It may prohibit the regular use of purchased sermon manuscripts. It may expect acknowledgment when substantial portions of another preacher’s sermon are reproduced. It may establish boundaries concerning artificial intelligence. And it may conclude that a pastor who systematically conceals his dependence upon others has violated the congregation’s trust. But those judgments belong first to the church because the pastor is accountable to the church for the ministry he performs among them.
The New Testament consistently locates responsibility for recognizing, evaluating, supporting, correcting, and, when necessary, disciplining church leaders within the life of the local church. Congregations participate in recognizing their officers (Acts 6:3–6); elders must satisfy publicly identifiable qualifications (1 Tim. 3:1–7; Titus 1:5–9); accusations against elders receive comparable procedural safeguards, and elders who persist in sin are to be publicly rebuked (1 Tim. 5:19–20). More broadly, Christ entrusts the exercise of church discipline to the assembled church (Matt. 18:17–20; 1 Cor. 5:4–5).
Historic Baptist ecclesiology reflects the same conviction. The Second London Baptist Confession teaches that Christ has invested each gathered church with the authority necessary for its worship and discipline.6 Churches may seek outside counsel in difficult controversies, but such advisers possess no jurisdiction over the church or its officers.7
And different churches may reasonably establish different expectations. A small congregation with a bivocational pastor may knowingly encourage him to make extensive use of sermon helps, published outlines, or trusted preaching resources. Another church may employ a full-time preaching pastor with the explicit expectation that a large portion of his week will be devoted to original exegetical preparation. A church might be comfortable with its pastor adapting another minister’s sermon while another expects substantial dependence to be disclosed.
Those differences do not require us to discover which church has identified the universal Christian standard. Scripture gives churches considerable freedom to order their ministries according to wisdom while remaining within biblical boundaries. What matters is honesty about those expectations. If a congregation has called a pastor with the clear understanding that he will perform substantial personal sermon preparation, and he instead secretly purchases complete sermons every week, the resulting problem is not difficult to identify. He has failed to perform work reasonably expected of him and concealed that failure from the people he serves. That may indeed be serious sin.
But notice how different that analysis is from running two manuscripts through comparison software, identifying matching phrases, and announcing a percentage. Textual similarity can establish literary dependence. It cannot, by itself, establish deception, laziness, theft, pastoral abdication, or ministerial disqualification. Those conclusions require context. They require knowing what kind of material was borrowed, how extensively it was used, whether the pastor understood and evaluated it, what representations he made about his preparation, what expectations his church had established, and whether he actually performed the pastoral work entrusted to him. That is especially important when accusations become public.
There is a considerable moral distance between saying, “These sermons contain substantial unattributed dependence upon another source,” and saying, “This pastor is a thief, a liar, or disqualified from ministry.” The first may be demonstrable through textual comparison. The second is a moral and ecclesiastical judgment requiring considerably more evidence.
Christians who rightly insist that local churches possess authority to evaluate their pastors should be reluctant to replace that authority with an informal tribunal of academics, conference leaders, plagiarism software, or social media commentators applying standards the congregation itself never adopted. A church may ultimately conclude that its pastor’s use of other material demonstrates dishonesty serious enough to warrant discipline or removal. But it should reach that conclusion by asking biblical and pastoral questions, not purely academic ones.
Faithfulness, Not Novelty
Sermon plagiarism can be sinful. Sometimes grievously so. A pastor can lie. He can steal. He can deceive his congregation about the work he performs. He can collect a salary for responsibilities he habitually neglects. He can become dependent upon other preachers to such an extent that he ceases meaningfully to study, discern, and shepherd. None of those possibilities should be minimized. But neither should they be collapsed into the proposition that using another person’s words without attribution is always theft and therefore always sin.
Academic institutions need rigorous plagiarism standards because academic work frequently exists to demonstrate intellectual provenance, independent research, and original contribution. The pulpit exists for another purpose. The preacher is not writing a term paper. He is preaching the Word. His congregation should therefore care far more about whether he understands the text than whether every formulation originated with him; whether he exercises theological discernment rather than whether his outline appeared somewhere before; whether his applications faithfully address the sheep entrusted to him rather than whether an algorithm regards his prose as sufficiently unique.
Borrowing can become deception. Dependence can become laziness. Using another man’s work can become pastoral abdication. Churches should take all of those things seriously. But originality is not faithfulness. Indeed, the rise of generative artificial intelligence should finally make that distinction obvious. We now possess machines capable of producing endless quantities of original religious prose. If generating novel sentences were the essence of sermon preparation, the pastoral shortage could be solved with a subscription fee. Yet the church needs something much older and much harder to manufacture: qualified shepherds who know Scripture, know their people, recognize truth, reject error, exercise wisdom, and faithfully feed the flock.
The question we ask about a sermon should therefore not begin and end with, “Whose words are these?” Instead, we should ask the more important questions:
Is it true? Does the preacher understand it? Has he exercised the pastoral judgment entrusted to him? Has he been honest with his congregation? And has he faithfully brought the Word of God to bear upon the people God has called him to shepherd?
Those questions will not produce a neat similarity percentage. But they will tell us considerably more about whether a preacher has been faithful.
