The Greek verb apodeiknumi means to show forth, demonstrate, or prove something publicly — to present evidence that establishes a fact beyond reasonable doubt. It was used in rhetoric for formal proof and in official contexts for public appointment or display.
Apodeiknumi appears in Peter's Pentecost sermon (Acts 2:22): 'Jesus of Nazareth was a man accredited (apodeiknumi) by God to you by miracles, wonders and signs.' The miracles were God's public proof, his divine attestation of Jesus' identity and authority. The word is significant: the resurrection was not merely an event but a demonstration — the ultimate apodeiknumi that validated every claim Jesus made. Paul uses it in 1 Corinthians 4:9 of apostles being 'displayed' as a spectacle before the world — a darker sense of being put on public show through suffering.
