Augustine of Hippo
The portrayal of the ruler on the currency differs from that of his child; both feature an image, yet the representation on the coin is distinct. The son reflects one likeness, while the gold piece shows another. In this sense, you too are a creation of God, yet in a far superior way, for you are aware, both in thought and in your life, of the divine image that resides within you, and of the likeness in which you were crafted! (Cf. Gen. 1:26-27; 2 Cor. 3:2-3.) However, a mere piece of currency does not comprehend that it carries the likeness of the Sovereign.
Upon revealing the coin, you were left without defense, compelled to confront your own dishonesty. In that moment, it was declared to you, ‘Render unto Caesar the things that are Caesar's, and unto God the things that are God's’ (Matthew 22:21), especially after you acknowledged that the coin displayed Caesar's likeness. Just as Caesar looks for his image in currency, so too does God seek His image in humanity.
