Christ did not give to Caesar. When confronted by the religious leaders of the day in an attempt to trip him up, Jesus said "Render unto Caesar the things that are Caesar's but to God the things that are God's." This begs the question, "What belongs to Caesar?" Does Caesar own whatever he happens to claim, or is he a thief and a robber?

BTW, Jesus said this after someone produced a coin with Caesar's face on it... the key question here is "What belongs to God?" Whose image and inscription is on every human being? In Whose image is man made? To Whom does every man belong? If I belong to God, what does that leave for Caesar to claim?
