Jesus' answer exceeds the exact limits of the question asked him. His addition, "give to God what is God's" (v. 25), is essential to his understanding of political authority. If ultimate authority belongs to God, then political allegiances must also be subordinated to God. In v. 25 the unmistakable exousia, or authority, of Jesus again emerges. Caesar and God vied for ultimate authority in the political and religious climate of Jesus' day, yet Jesus presumes to speak for both. That ultimate authority resided with God is clearly implied in Jesus' use of "image" (v. 24; Gk. eikÅn), the same word used in Gen 1:26 of humanity's creation in God's image. If coins bear Caesar's image, then they belong to Caesar. The Greek verb apodidonai (v. 25) reinforces this point, for it means to give back to Caesar what already belongs to him. But the same verb is also applied with reference to God. Humanity bears God's image. Humanity must therefore render ultimate submission to the God in whose image it is made.Pillar Luke Commentary (Luke 20:24)
