And Jesus answering said unto them,
Render to Caesar the things that are Caesar's, and to God the things that are God's.
And they marveled at him.
All Commentaries on Mark 12:17 Go To Mark 12
Tertullian of Carthage
AD 220
That means render the image of Caesar, which is on the coin, to Caesar, and the image of God, which is imprinted on the person, to God. You give to Caesar only money. But to God, give yourself.
