### Core Meaning & Semantic Range
The Greek word **diakatelénchomai**, represented by `{{G1246}}`, means **to prove downright** or to confute, and is translated as **convince**. This specific term appears only **1 time** in **1 unique verse** in the entire Bible, highlighting a very particular and forceful type of argument. Its definition implies a thorough and decisive refutation of opposing views.
### Biblical Occurrences & Contextual Analysis
The sole use of `{{G1246}}` is found in [[Acts 18:28]], which describes the ministry of Apollos. The verse states that he "mightily **convinced** the Jews, and that publickly, shewing by the scriptures that Jesus was Christ." This context demonstrates that the conviction was not a simple discussion, but a powerful, public, and evidence-based argument rooted in scripture. Apollos effectively confuted the Jewish arguments by using their own holy writings to prove the identity of Jesus.
### Related Words & Concepts
Several related Greek words from its only context in [[Acts 18:28]] help clarify its meaning:
* `{{G2159}}` **eutónōs** (in a well-strung manner, i.e. (figuratively) intensely (in a good sense, cogently; in a bad one, fiercely):--mightily, vehemently): This adverb specifies the intense and cogent manner of the conviction. It is also used to describe how fiercely the chief priests accused Jesus [[Luke 23:10]].
* `{{G1124}}` **graphḗ** (a document, i.e. holy Writ (or its contents or a statement in it):--scripture): This is the basis of the conviction. The scriptures are the source of proof, and all **scripture** is described as profitable for doctrine and reproof [[2 Timothy 3:16]].
* `{{G1925}}` **epideíknymi** (to exhibit (physically or mentally):--shew): This action of "shewing" is the method of conviction. Apollos was **shewing** from the scriptures, presenting them as evidence to prove his point [[Acts 18:28]].
* `{{G1219}}` **dēmósios** (public; (feminine singular dative case as adverb) in public:--common, openly, publickly): This indicates the open forum for the argument. The conviction was done **publickly**, demonstrating that it was a proclamation for all to hear [[Acts 18:28]].
### Theological Significance
The theological weight of `{{G1246}}` is centered on the nature of Christian apologetics and evangelism.
* **Scriptural Proof:** The act of convincing is explicitly tied to the use of the scriptures `{{G1124}}`. The power of the argument in [[Acts 18:28]] comes not from human wisdom but from "shewing by the scriptures" that Jesus is the Christ, aligning with Jesus' own statement that the scriptures testify of him [[John 5:39]].
* **Public Witness:** The conviction was performed **publickly** `{{G1219}}`, establishing a pattern of open, reasoned defense of the faith. It was a mighty `{{G2159}}` and visible demonstration intended for the community.
* **Christ-Centered Proclamation:** The ultimate goal of this powerful conviction was to establish the identity of Jesus `{{G2424}}` as the **Christ** `{{G5547}}`. This highlights the central message of the early church: that the long-awaited Messiah had come in the person of Jesus [[Acts 18:28]].
### Summary
