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.
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.
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.
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.
In summary, while G1246 is a rare word, its single appearance provides a powerful snapshot of early Christian apologetics. It encapsulates a method of evangelism that is not only vocal but also vigorous, public, and, most importantly, grounded in the authoritative testimony of scripture. The word diakatelénchomai represents a complete and compelling argument designed to convince an audience of the central truth that Jesus is the Christ.
