Tell us therefore what dost thou think, is it lawful to give tribute to Caesar, or not? But Jesus knowing their wickedness, said: Why do you tempt me, ye hypocrites? She’s me the coin of tribute. And they offered him a penny. And Jesus saith to them: Whose image and inscription is this? They said to him: Caesar’s. Then he saith to them: Render therefore to Caesar the things that are Caesar’s; and to God, the things that are God’s.
” On the threefold image of God: ‘Show me the coin of tribute’
Note that the image is threefold: of likeness, of creation (in which man is created, namely reason), and of restoration, by which the created image is restored, namely the grace of God which is infused into the mind to be renewed.
The image of likeness is that according to which man was made in the image and likeness of the whole Trinity.
By memory he is like the Father, by understanding like the Son, by love like the Holy Spirit.
So St Augustine says, ‘Let me remember you, understand you, and love you.’
Man was made in the image and likeness of God (cf. Gen 1:26-27): his image in the understanding of truth, his likeness in love of virtue.
The light of God’s countenance is the grace of j stification, whereby the created image is imprinted.
The light is the whole and true good of man, whereby he is marked like a penny with the king’s image.
That is why the Lord adds in this Gospel: Render to Caesar the things that are Caesar’s, etc. It is as if he said: ‘As you give back to Caesar his image, so give back your soul to God, enlightened and signed with the light of his countenance.'”
