At the same time, also, this doctrine of exceeding wisdom is introduced, that the Lord God is the only real citizen, and that every created being is but a stranger and a sojourner. But those who are called citizens are called so rather in consequence of a slight misapplication of the name than in strict truth. And it is a sufficient gift to wise men—if considered comparatively with the only true citizen, God—for them to have the rank of strangers and sojourners. With respect to foolish men, of them there is absolutely no one who is a stranger or sojourner in the city of God, but such an one is found to be utterly an exile. And this is implied in what he said besides as a most authoritative doctrine, "The land shall not be utterly sold away." Nor did God add "by whom," in order that from that point being passed over in silence, he who was not wholly uninitiated in natural philosophy, might be benefited in respect of knowledge.

Therefore, if you consider the matter, you will find that all men, and especially those who have been alluded to as giving gratuitously, sell rather than give; and that they, who we fancy are receiving favours, are, in reality, purchasing the benefits which they derive; for they who give, hoping to receive a requital, such as praise or honour, and seeking for a return of the favour which they are conferring, under the specious name of a gift, are, in reality, making a bargain. Since it is usual, for those who sell, to receive a price in return for what they part with; but they who, receiving presents, feel anxiety to make a return for them, and make such a return in due season, they in reality perform the part of purchasers; for as they know how to receive, so also do they know how to requite.

But God distributes his good things, not like a seller vending his wares at a high price, but he is inclined to make presents of everything, pouring forth the inexhaustible fountains of his graces, and never desiring any return; for he has no need of anything, nor is there any created being competent to give him a suitable gift in return.

As all things then are confessed to be the possessions of God, and proved to be so by sound reasonings and testimonies, which cannot possibly be convicted of bearing false witness, for they are the sacred oracles which Moses has recorded in the Holy Scriptures that bear witness; we must deprecate that mind which fancied that that which originated in a meeting with the outward sense was his own property, and which called it Cain, and said, "I have gotten a man by means of God," in this also greatly erring. But in what did he err?

Because God was the cause, not the instrument; and what was born was created indeed through the agency of some instrument, but was by all means called into existence by the great first cause; for many things must co-operate in the origination of anything; by whom, from what, by means of what, and why? Now he by whom a thing originates is the cause; that from which a thing is made is the material; that by means of which it was made is the instrument; and why, is the object.
