14. With this Finger, as we read, God wrote on those tables of stone which Moses received. For God did not with a finger of flesh write the forms and portions of those letters which we read, but gave the law by His Spirit. And so the Apostle says: “For the Law is spiritual, which, indeed, is written not with ink, but with the Spirit of the living God; not in tables of stone, but on fleshy tables of the heart.” For if the letter of the Apostle is written in the Spirit, what hinders us from believing that the Law of God was written not with ink, but with the Spirit of God, which certainly does not stain but enlightens the secret places of our heart and mind?
