Something I wrote on a Charles Williams discussion board
The coin is such an interesting image in the gospels . . . the parable of the lost coin, the parable of the talents (where the Master himself is an investor), the coin that Peter catches in a fish, and of course the Roman Denarius that Jesus lifts into our attention: "Whose image do you see on it?" . . . "Give to Caesar what is Caesar's; to God what is God's" This brings a number of truths to light. First that our participation in human exchange, on most its basic levels (both physical and spiritual) owes something real, a true allegiance, to Caesar (or the analogous magistrate), something that is figured in the currency that bears his image. Secondly, that we are called to enter into an analogous exchange with God, only the stakes (as Pascal might say) are infinite. Just as to do honor to the emperor's image we must run risks, venture our capital, for God we must run the ultimate risk, make an unretractable investment, in the only coin which is current in the Kingdom, our very being, stamped with his image -- through which exchange we honor our co-inherence with God, and are more fully united to Him. Somewhere in "The Descent of the Dove" Williams talks about money as the symbol of human co-inherence, but I don't have a copy handy. Anyone know the reference?
