Lecture 11-3: Guidelines for Honesty, Authorship, and Preaching Ethics

Ephesians 4:25 — "Therefore putting away falsehood, speak truth each one with his neighbor. For we are members of one another." (World English Bible)

2 Corinthians 4:2 — "But we have renounced the hidden things of shame, not walking in craftiness, nor handling the word of God deceitfully; but by the manifestation of the truth commending ourselves to every man's conscience in the sight of God." (WEB)

Ephesians 5:9 — "for the fruit of the Spirit is in all goodness and righteousness and truth," (WEB)

3.1 What a congregation actually trusts, and what it does not

It is worth being precise about the specific trust at stake, because overstating it produces an unworkable standard and understating it produces no standard at all.

A congregation does not trust, and has never trusted, that a sermon is the product of the preacher's mind operating in isolation from every other influence. Sermons have always been shaped by commentaries, systematic theologies, other preachers' recorded sermons, conversations, personal counseling experience, and — for centuries now — inherited outlines and illustrations passed through preaching traditions with no attribution at all. None of this has ever been regarded as a breach of trust requiring disclosure, because the relevant trust was never about the sermon's causal history in that sense.

What a congregation does trust is that the sermon represents the preacher's own settled conviction — that when the preacher says "I believe this text teaches," the preacher actually, personally believes it, has tested it against Scripture and conscience, and stands behind it as a claim the preacher is prepared to be held accountable for, including in private conversation afterward if a hearer pushes back on it. This is a trust about the preacher's relationship to the content delivered, not about the content's causal origin. A sermon heavily informed by a particular commentator's reading violates no trust, because the preacher has still made that reading the preacher's own through study and conviction. A sermon substantially generated by an AI system and delivered without the preacher's own substantive engagement violates this trust precisely because the "I believe" implicit in preaching is no longer straightforwardly true — the preacher is presenting as personal conviction something that was, in the relevant sense, someone (something) else's output, adopted rather than arrived at.

3.2 Ephesians 4:25 and 2 Corinthians 4:2 as the operative standard

Ephesians 4:25 sits inside Paul's practical instructions for the "new self" the Ephesians are to put on, and its logic is unusually direct: "putting away falsehood, speak truth each one with his neighbor. For we are members of one another" (WEB). The reason given for truth-telling is not merely that lying is wrong in the abstract, but that the community is a single body ("members of one another") whose functioning depends on members being able to trust what other members tell them. A congregation is exactly this kind of body with respect to its preacher, and a preacher who allows a congregation to believe a sermon represents personal conviction when it substantially does not has introduced exactly the kind of falsehood this verse addresses — not a lie about a fact within the sermon, necessarily, but a lie (or at minimum, an uncorrected false impression) about the sermon's own status.

2 Corinthians 4:2 is even more pointed for preaching specifically, because Paul states it as a description of his own ministerial practice: "we have renounced the hidden things of shame, not walking in craftiness, nor handling the word of God deceitfully; but by the manifestation of the truth commending ourselves to every man's conscience in the sight of God" (WEB). Paul names "handling the word of God deceitfully" as a live temptation for a preacher specifically — not a generic sin any person might commit, but a specific occupational hazard of the preaching task, presumably because a preacher has unusual opportunity and unusual cover to shape what a congregation believes without full transparency about how. The remedy Paul states is "manifestation of the truth" — open dealing, examined by the hearer's own conscience — as opposed to craftiness, which trades on the hearer not being able to see clearly what is actually happening. A preacher who conceals substantial AI authorship of a sermon's content, allowing the congregation to believe it is receiving the preacher's own wrestled conviction, is engaged in something close to what Paul names here: not deceit about the sermon's content, necessarily, but deceit about its status, concealed under cover of a form (preaching) the congregation has no independent way to audit.

3.3 A concrete guideline, stated honestly as imperfect

Building on 11-1's distinction between legitimate and illegitimate AI use, this lecture proposes a working guideline for disclosure specifically:

AI used as a research assistant — the legitimate uses named in lecture 11-1 (word studies, cross-reference lookup, structural brainstorming later substantially reshaped, clarity-checking a manuscript the preacher already wrote) — does not require disclosure, for the same reason consulting a commentary or a colleague does not require disclosure. The preacher has still done the work of forming personal conviction; the tool informed that work without replacing it.

AI-drafted content substantially adopted and presented as the preacher's own reflection — an illustration the preacher did not personally experience presented as though it were personal experience, an exegetical conclusion generated by the tool and preached without the preacher's own independent verification and ownership of it, or a sermon whose content the preacher did not substantially originate — is not fine, and disclosure does not cure the underlying problem, because the issue is not merely that the congregation was not told; it is that the sermon is not, in the sense the congregation is entitled to assume, the preacher's own.

This lecture states plainly that this guideline, however useful, does not resolve every case cleanly. A preacher who asks an AI system for "three possible illustrations of costly forgiveness" and then substantially rewrites one in the preacher's own words and adds a genuinely personal application has arguably stayed on the legitimate side of the line — the core creative and reflective work is still the preacher's — even though the initial prompt for the idea came from the tool. A preacher who takes that same illustration nearly verbatim and delivers it as though recalling a personal memory has clearly crossed the line, and has compounded the authorship problem with an outright factual falsehood about where the illustration came from (a case flagged already in 11-1, and sharpened here). Between these two relatively clear cases lies real ambiguity — how much rewriting and personal ownership is enough — that this lecture does not claim to resolve with a bright line, because none likely exists that would not be either too permissive or too restrictive for the range of actual cases a preacher will face.

3.4 The positive standard, not only the prohibition

Ephesians 4:25 and 2 Corinthians 4:2 state what to avoid. Ephesians 5:9 supplies the positive posture this lecture wants a preacher to aim at rather than merely the violation to steer around: "for the fruit of the Spirit is in all goodness and righteousness and truth" (WEB). The verse names truth not as an isolated rule to comply with under threat of violation, but as one strand of a single fruit that also includes goodness and righteousness — truthfulness in preaching is not a bare compliance standard but an expression of the same Spirit-formed character that should also be producing goodness (genuine care for what serves the congregation) and righteousness (a rightly ordered relationship to God and neighbor) in the preacher generally.

Framed this way, the question "must I disclose this?" is the wrong first question, useful mainly at the margins where genuine ambiguity remains (as in 3.3). The better first question, closer to what Ephesians 5:9 is actually asking of the preacher, is whether the preacher's use of any tool — AI included — is consistent with a settled character of goodness, righteousness, and truth toward the congregation, such that the preacher would be entirely comfortable naming exactly how the sermon was prepared if a member asked directly, with no need to hope the question does not come up. A preacher whose honest answer to "how was this sermon prepared?" would be uncomfortable to give has very likely already crossed the line this lecture has been describing, whatever formal disclosure policy is or is not in place — and a preacher whose honest answer would be unremarkable to give has very likely stayed within it. This is not a legal test designed to survive every hypothetical; it is a pastoral test aimed at the actual conscience of an actual preacher, which is, this lecture argues, where questions of preaching ethics ultimately have to be settled.
