ἔλεγχος

a proof, persuasion, reproof

Definition

The noun ἔλεγχος (elegchos) carries a nuanced range of meanings centered on the idea of convincing demonstration. Its primary sense is that of a 'proof' or 'conviction,' referring to something that provides undeniable evidence, as seen in Hebrews 11:1 where faith is the 'conviction' (proof) of things not seen. It also encompasses the concept of 'reproof' or 'rebuke,' indicating a correction that convincingly exposes error, which is its meaning in 2 Timothy 3:16, stating Scripture is profitable for 'reproof.' The term thus bridges the ideas of proving truth and disproving falsehood through compelling evidence.

Biblical Usage

This word is used only twice in the New Testament, in two distinct but related contexts. In 2 Timothy 3:16, it is used in a pastoral and instructional sense regarding the function of Scripture for 'reproof,' meaning to convict and correct doctrinal or moral error. In Hebrews 11:1, it is used in a philosophical and theological sense, defining faith as the 'conviction' or 'proof' of spiritual realities. Despite the different contexts, both uses share the core idea of a powerful, convincing demonstration that leads to certainty.

Etymology

Derived from the verb ἐλέγχω (elegchō, G1651), which means 'to convict, expose, prove wrong.' The noun form, ἔλεγχος, developed to signify the result or means of that action—the 'conviction,' 'proof,' or 'reproof' itself. In classical Greek, it was used in legal, philosophical, and rhetorical contexts for cross-examination and refutation, carrying into Koine Greek this sense of compelling demonstration of truth or error.

Semantic Range

This word is theologically significant as it defines a key function of Scripture and a core component of faith. In 2 Timothy 3:16, it highlights Scripture's role not just in teaching but in actively convicting and correcting believers, essential for spiritual maturity and sound doctrine. In Hebrews 11:1, it anchors the very definition of faith not as blind hope, but as a firm 'conviction' based on divine evidence, enriching our understanding of biblical faith as a settled certainty granted by God.

In its Greco-Roman cultural setting, ἔλεγχος was a term from logic, rhetoric, and law, referring to the process of proving a case or refuting an opponent through irrefutable argument. This background gives depth to its biblical use: the 'reproof' of Scripture (2 Timothy 3:16) is not a mere scolding but a logical, authoritative correction, and faith's 'conviction' (Hebrews 11:1) is presented as a rational certainty, countering any notion of faith as irrational in the ancient world.

ἐλέγχω (elegchō, G1651) — the verb form meaning 'to convict, reprove, or expose.' διόρθωσις (diorthōsis, G1882) — emphasizes correction or setting right, more on restoration than conviction. νουθεσία (nouthesia, G3559) — focuses on admonition or warning, often with a teaching intent.
