Word Studies Done Properly

A word study done badly still feels like scholarship, because it involves a lexicon, a Greek or Hebrew term, and a confident conclusion. The fallacies below are named precisely because they are common enough, and persuasive enough, to need names.

The root fallacy assumes a word's meaning is determined by its component parts or historical derivation, as though ekklesia must mean 'the called-out ones' because it is built from ek and kaleo. It is not how living language works in any period, including the first century; a word's current, ordinary use governs its meaning, not the pieces it was assembled from generations earlier. The closely related etymological fallacy makes the same mistake in a slightly different direction, appealing to a word's history or its cognate in another language to fix its meaning, the way pointing out that English 'nice' comes from a Latin word meaning 'ignorant' tells you nothing useful about what 'nice' means today.

Illegitimate totality transfer, a term coined by James Barr, is the error of loading every possible sense a word can carry anywhere in its range into one specific occurrence, as though a single use of logos should be heard as simultaneously meaning 'word,' 'reason,' 'account,' and 'matter' all at once, because the lexicon lists all four. Context selects one sense at a time; a lexicon entry is a menu of possibilities across many contexts, not a stack of meanings all present in every serving.

Anachronism reads a later, often more developed or technical sense of a word back into an earlier text that could not have carried it, treating baptizo in a first-century narrative as though it already meant everything later church controversies loaded onto it, or treating dynamis as though it already carried the modern, post-1867 sense of controlled explosive force.

Finally, there is the simple but common assumption that a single Greek or Hebrew word should always be translated by the same single English word wherever it occurs, and that a single English word always translates the same underlying original. Neither is true. Logos can be word, message, account, or reason depending on context; English 'know' can translate several distinct Hebrew and Greek verbs with different shades of meaning. Word studies that quietly assume a fixed one-to-one correspondence between languages will mislead a student who has not been warned.

Dynamis and dynamite is the cleanest case of anachronism in popular preaching. Dynamis, used across the New Testament for power, ability, or capability, most famously in Romans 1:16, where Paul calls the gospel 'the power of God for salvation,' is regularly preached as though Paul meant something like an explosive charge, ready to detonate. The connection runs backward: Alfred Nobel named his 1867 invention 'dynamite' after the existing Greek word dynamis, precisely because it meant power in general, not because the Greek word already carried any sense of controlled combustion. Paul's readers heard a word for capability and strength, the same word used of God's power to raise the dead (Ephesians 1:19-20) and of ordinary human ability; they heard nothing that would suggest an explosion.

The overdrawn agape-versus-phileo distinction is more stubborn because it survives on a passage that looks, on first glance, built to support it: John 21:15-17, where Jesus asks Peter twice with agapao and once with phileo, and Peter answers all three times with phileo. Generations of preachers have read this as Jesus asking for a higher, sacrificial love and settling, in the third question, for the lesser love Peter can actually offer. That reading does not hold up well on two counts, though the two words are not simply identical in every context either. First, the exchange varies several other word pairs at the same time, feed and shepherd, lambs and sheep, in a pattern that looks like John's ordinary stylistic variety rather than one carefully isolated theological substitution. Second, and more decisively, John's Gospel elsewhere uses agapao and phileo for the identical relationship without any evident difference in meaning: John 3:35 says the Father agapa the Son, and John 5:20 says the Father philei the Son, describing the same love. If phileo marked something lesser than agapao, John could not use it here of the Father's love for the Son. None of this means the two words never carry different shades anywhere in Greek; it means this particular passage cannot be the proof text for a fixed hierarchy between them. The steadier reading of John 21 is that Jesus presses Peter three times, which many readers connect to Peter's three denials even though the text never states that link outright, using the ordinary stylistic variety of a writer who did not treat agapao and phileo as separated by a wall.

Hilasterion, used of Christ in Romans 3:25 (the BSB prints "God presented Him as an atoning sacrifice in His blood through faith," with a footnote offering "as a propitiation" as the alternative, so even the BSB signals that the word is disputed) and in Hebrews 9:5 of the mercy seat, the golden cover of the ark of the covenant in the Septuagint's rendering of the Hebrew kapporet, sits at the center of a genuine and still-live scholarly debate rather than a simple error to correct. C. H. Dodd, in a 1931 article in the Journal of Theological Studies and again in his 1935 book The Bible and the Greeks, argued that hilasterion and its word family in the Greek Old Testament regularly mean 'expiation,' the removal or cleansing of sin, without the sense of appeasing an angry deity that 'propitiation' implies in English, and that pagan usage of related words for placating hostile gods should not be read into Paul. Leon Morris, in his 1955 book The Apostolic Preaching of the Cross, argued in reply that Paul's own case in Romans 1:18 through 3:20, which spends three chapters establishing God's wrath against sin before arriving at 3:25, requires that the wrath actually be addressed and not merely the sin removed, and that 'propitiation' captures something 'expiation' alone does not. Both scholars did careful lexical work, and neither has simply won the point: Dodd's evidence about the word family's ordinary Greek usage stands on its own, and so does Morris's observation that ordinary usage cannot by itself tell you what one heavily-argued passage needs the word to be doing. The disagreement is not solved by a lexicon entry, because the two readings differ on what the whole argument of Romans requires at this specific point, which a lexicon cannot answer alone.

James Barr's The Semantics of Biblical Language, published by Oxford University Press in 1961, is the landmark critique behind most of what this lesson has named. Barr, an Old Testament scholar, argued at length against a style of biblical theology, common in his day, that built doctrinal claims on the supposed etymology or root meaning of Hebrew and Greek words, and against the assumption that Hebrew and Greek each encode a distinctive 'mentality' recoverable from their vocabulary. His central methodological point, drawn from the linguistics of his time, was that meaning belongs to whole utterances in context, not to words in isolation, and that a word's history is a poor guide to what it means on a given occasion of use.

D. A. Carson's Exegetical Fallacies, first published in 1984, is the accessible companion, written for students and pastors rather than for professional linguists, and it is where most seminary students meet these fallacies by name for the first time, including the root fallacy, illegitimate totality transfer, and several others besides the ones this lesson has covered. Carson's stated aim was not to discourage word study but to make it more careful, by showing, through worked examples very much like the ones above, how easily good intentions produce bad exegesis.

Both writers make the same basic point from different angles: word studies are valuable and even necessary, but the value depends entirely on method. A word study that begins with etymology and ends with a doctrine has usually gotten the process backward.

Start by identifying the lemma, the dictionary form of the word, rather than stopping at the one inflected form in front of you. Blue Letter Bible's interlinear tool and Strong's numbering, and STEP Bible's tagged texts, both free, will show you the lemma behind any English word in seconds, along with its Strong's number if you want to search further by that number.

Find every occurrence of that lemma across the relevant corpus, not just the handful a memory verse collection happens to include. Blue Letter Bible's Strong's search and STEP Bible's lemma search both return a full list of occurrences for free; this step alone is what separates a word study from an impression.

Sort what you find by author and by approximate date. A word's usage in the Septuagint two centuries before Paul, in classical Attic Greek four centuries before that, and in Paul's own letters are three different bodies of evidence, and usage drifts across time and community the way any living language's usage does; treating them as one undifferentiated pool is where several of the fallacies above sneak back in.

Let usage in context set the range of meaning for each occurrence, rather than importing the full lexical range into every verse (the error Barr named illegitimate totality transfer). Blue Letter Bible and STEP Bible both give free, full access to the lexicons built to list that range: Thayer's Greek Lexicon and Liddell-Scott for Greek, and Brown-Driver-Briggs (BDB) for Hebrew, all public-domain works included in both tools at no cost, alongside Tyndale House's own tagging on STEP Bible. The specific context in front of you selects from the range a lexicon lists; it does not add to it. BDAG (Bauer, Danker, Arndt, and Gingrich's Greek lexicon, from the University of Chicago Press) and HALOT (the Hebrew and Aramaic Lexicon of the Old Testament, from Brill) are the paid academic standards many seminaries require and neither is available free on Blue Letter Bible or STEP Bible; worth naming so a student knows what they are if a professor mentions them, and worth saying plainly that a diligent student can do sound word-study work for years without ever needing to buy either.

Finally, prefer the same author's usage nearby over usage from a different book, writer, or era. Paul's use of a term elsewhere in Romans, or across his letters generally, is a better guide to what he means by it in Romans 3 than a classical Greek usage four centuries earlier or another New Testament author's usage in a different genre. Nearness in authorship and time is not a guarantee of identical usage, but it is the best available evidence, and it is exactly the evidence a student can gather for free, in an afternoon, using tools built for precisely this task.
