Topical Lexicon
Occurrences in Scripture

Luke 23:10 – “The chief priests and scribes were standing there, vehemently accusing Him.”

Acts 18:28 – “For he powerfully refuted the Jews in public debate, proving from the Scriptures that Jesus is the Christ.”

Contextual Usage

1. Judicial Hostility (Luke 23:10)

The adverb intensifies the animosity of the religious leaders during Jesus’ Roman trial. Their “vehement” accusations underscore the depth of opposition from the very shepherds of Israel who should have recognized their Messiah. The word paints a courtroom scene charged with passion, bias, and spiritual blindness, contrasting sharply with the silent dignity of Jesus (Isaiah 53:7).

2. Apologetic Fervor (Acts 18:28)

Applied to Apollos in Corinth, the term highlights persuasive strength in proclaiming Christ from the Hebrew Scriptures. His ministry followed the pattern of Paul, demonstrating that authentic Christian preaching engages both heart and mind, forcefully yet graciously dismantling objections (2 Corinthians 10:4-5).

Historical Background

Luke’s Gospel and Acts form a two-volume work addressed to Theophilus, emphasizing the certainty of the gospel narrative (Luke 1:4). In Luke, the word captures the climax of Jewish rejection; in Acts, it illustrates the ongoing vindication of Jesus through Spirit-empowered witnesses. The same historian records both scenes, inviting readers to observe that the cross did not end Jesus’ story—resurrection power now fuels His followers’ bold witness.

Theological and Ministry Implications

• Spiritual Opposition Is Intense. Jesus faced vehement hostility; His servants should not be surprised by similar resistance (John 15:18-20).
• Truth Must Be Declared With Conviction. Apollos’ vigorous defense models a Spirit-filled boldness that relies on Scripture’s sufficiency.
• The Word Cuts Both Ways. The same intensity that fueled unjust accusations in Luke reveals the sinfulness of man, while in Acts it reveals the power of redeemed speech guided by the Spirit (Ephesians 6:17).

Practical Application

• Preachers and teachers should cultivate thorough knowledge of Scripture so their proclamation can be “powerful” rather than merely emotional.
• Believers facing hostility may take comfort: Christ Himself endured worse, and His vindication guarantees ultimate justice.
• Churches should encourage Apollos-like discipleship—grounding believers in the Old and New Testaments to defend the faith “eutonos,” strongly yet respectfully (1 Peter 3:15).

Related Biblical Themes

• Boldness in Witness: Acts 4:31; Philippians 1:14.
• The Authority of Scripture: 2 Timothy 3:15-17.
• Persecution of the Righteous: Psalm 37:12-13; 2 Timothy 3:12.
