Lexical Fallacies Ministers Keep Making
Five errors that recur in pulpit Greek and Hebrew. Each is correctable; the discipline is noticing when you are about to commit one.
The lexical fallacies are a well-known list among scholars and a recurring problem in pulpits. They keep happening because they preach beautifully — each one produces a vivid claim that lands. The discipline is to notice when you are about to commit one and choose a more honest move instead.
Five recur often enough to be worth naming explicitly.
The root fallacy
The root fallacy treats the etymological root of a word as its meaning. The classic example is preaching that ἐκκλησία ("church") "really means called-out ones" because its components are ἐκ ("out of") and a verbal stem related to calling. The components are real. The semantic claim is folklore.
By the time a word is in use, its meaning is determined by usage, not by the meanings of its parts. English does this too — "butterfly" is not a fly made of butter, and "understand" has nothing to do with standing under anything. Greek and Hebrew are the same.
The fix is to ask the lexicon what the word means in usage and ignore the etymology unless the lexicon itself flags it as relevant.
The illegitimate totality transfer
This one happens when a minister takes the entire semantic range of a word — every sense the lexicon lists — and imports all of it into the present passage. The result is a sermon point that draws on senses the writer never had in mind in this verse, because the writer was using the word in one sense and one sense only.
If your sermon point depends on the word "carrying overtones" of a sense the construction does not support, you are probably doing illegitimate totality transfer. The fix is to identify which lexicon sense applies in this sentence and preach that sense.
The diachronic fallacy
The diachronic fallacy reads a later meaning of a word back into an earlier text. The most common version uses post-New-Testament patristic usage to determine New Testament meaning, or uses modern theological vocabulary to determine first-century vocabulary. The Greek word "evolved" — and the evolution was not yet present in the text you are preaching.
The fix is to ask what the word meant when this writer was writing. The lexicon will help. So will reading the writer's own other uses.
The cognate trap
A cognate is a related word, but a related word is not the same word. Sermons sometimes leap from a verb to its cognate noun and import the noun's range into the verb's meaning, or vice versa. The English equivalent would be using the meaning of "running" to determine the meaning of "runner" in a sentence where the difference matters.
Sometimes cognates do illuminate. Often they do not. Treat the cognate as a candidate piece of evidence, not as a free import.
The English-meaning import
The fifth fallacy is the most common and the easiest to commit. The Greek word ἀγάπη is sometimes translated "love." The English word "love" carries connotations — romantic, fond, sentimental — that the Greek word may or may not have. The minister hears the English word, thinks the English connotations, and preaches the connotations as if they were in the Greek.
This is sometimes harmless and sometimes very bad. The fix is to interrogate your own English associations and ask whether the lexicon supports them. Often it does not.
The shape of the fix
All five fallacies share a fix: ask the lexicon what the word means in this construction in this writer, and preach that. Resist the rhetorical pull of the more vivid claim that the lexicon will not defend.
This is not a counsel of dryness. The truth in the lexicon is usually richer than the folklore the fallacy produced. The minister who learns to read the lexicon well is the minister whose Greek and Hebrew become genuinely useful from the pulpit, rather than a source of slow-burning embarrassment.
