7 Now I have made these remarks because of those heretics who count possessions, and money, and men's bodies accursed. For I neither wish you to be a slave of money, nor to treat as enemies the things which God has given you for use. Never say then that riches are the devil's: for though he say, All these will I give you, for they are delivered unto me, one may indeed even reject his assertion; for we need not believe the liar: and yet perhaps he spoke the truth, being compelled by the power of His presence: for he said not, All these will I give you, for they are mine, but, for they are delivered unto me. He grasped not the dominion of them, but confessed that he had been entrusted with them, and was for a time dispensing them. But at a proper time interpreters should inquire whether his statement is false or true.
