Semantic Range Versus the Root Fallacy

A Greek or Hebrew word's meaning is determined by usage, not by etymology. This is one of those statements that scholars consider obvious and ministers occasionally find inconvenient, because etymology produces vivid sermon points and usage often does not.

The discipline is to know which one you are doing and to choose usage every time.

What semantic range is

A word has a semantic range — the set of meanings the word actually carries when speakers use it. The range is established by looking at how the word appears in the corpus: what it modifies, what it is contrasted with, what it stands in parallel with, what translators do with it.

The range is rarely a single point. ἀγάπη does not "mean" one thing. The lexicon catalogs the senses the word actually carries in the Greek of the relevant period. Some senses appear often, some rarely; some appear in particular constructions; some appear in particular authors. The range is structured but not monolithic.

When a sermon makes a claim about a word's meaning, the honest claim is about which sense from the range applies in this passage. Not what the word "really means," because there is no single thing the word really means. What it means here.

What the root fallacy is

The root fallacy works in the opposite direction. Instead of asking what the word's range is in usage, the minister breaks the word into its parts — its root, its prefix, its compound elements — and treats the parts as the meaning.

The example most familiar in pulpits is ἐκκλησία. The components are ἐκ ("out of") and a verbal stem related to calling. The root-fallacy reading: "the church is the called-out ones." The usage reading: by the time of the New Testament, ἐκκλησία means an assembly, with no remaining nuance of being "called out." The components are historical residue, not present meaning.

This is not unique to Greek. English does the same thing — "nice" originally meant "ignorant," and treating the modern word as if it carried that meaning would be ridiculous.

Why the root fallacy preaches well

The root fallacy preaches well because it produces a vivid claim. "The called-out ones" is a richer image than "an assembly." The minister gets a sermon point that lands. The congregation feels they have been let into the depth of the language.

What they have actually been given is a sermon point built on a meaning the writer did not intend. The writer wrote ἐκκλησία; they meant assembly. The sermon has substituted a different meaning, found through etymology, and presented it as exegesis.

The fix

The fix is to ask the lexicon what the word means in usage. The lexicon will give you the range. The range will give you the senses available to the writer. The construction in the verse will narrow the senses to the one the writer was using. That is the meaning you can defend.

If the lexicon's sense is less vivid than the etymology, that is information about the writer. The writer chose the less vivid sense. Preach what the writer chose.

The minister who develops this discipline will lose some vivid sermon points and gain a steadier kind of authority. Greek and Hebrew claims that are usage-based hold up over time. Greek and Hebrew claims that are etymology-based eventually embarrass the minister who made them.

The lexicon is the tool. Trust it more than the etymology, every time.
