Matthew 5:42

"Give to him that asketh thee, and from him that would borrow of thee, turn not thou away." These last are less than what went before; but marvel not, for this He is ever wont to do, mingling the small with the great. And if these be little in comparison with those, let them hearken, who take the goods of others, who distribute their own among harlots, and kindle to themselves a double fire, both by the unrighteous income, and by the pernicious outlay. But by "borrowing," here, He means not the compact with usury, but the use merely. And elsewhere He even amplifies it, saying that we should give to them, from whom we do not expect to receive.

If we understand this only of alms, it cannot stand with the estate of the most part of men who are poor; even the rich if they have been always giving, will not be able to continue always to give. But it maybe understood of the wealth of doctrine: wealth which never fails but the more of it is given away, the more it abounds.

Therefore, He says not, 'Give all things to him that asks;' but, Give to every one that asketh; that you should only give what you can give honestly and rightly. For what if one ask for money to employ in oppressing the innocent man? What if he ask your consent to unclean sin? We must give then only what will hurt neither ourselves or others, as far as man can judge; and when you have refused an inadmissible request, that you may not send away empty him that asked, show the righteousness of your refusal; and such correction of the unlawful petitioner will often be a better gift than the granting his suit. For with more benefit is food taken from the hungry, if certainty of provision causes him to neglect righteousness, than that food should be supplied to him that he may consent to a deed of violence and wrong. That He commands, And from him that would borrow of thee, turn not away, must be referred to the mind; for God loveth a cheerful giver. And every one that receives, indeed borrows, though it is not he that shall pay, but God, who restores to the merciful many fold. Or, if you like to understand by borrowing, only taking with promise to repay, we must understand the Lord's command as embracing both these kinds of affording aid; whether we give outright, or lend to receive again. And of this last kind of showing mercy it is well said, Turn not away, that is, do not be therefore backward to lend, as though, because man shall repay you, therefore God shall not; for what you do by God's command cannot be without fruit. Some object that this command of Christ is altogether inconsistent with civil life in Commonwealths; Who, say they, would suffer, when he could hinder it, the pillage of his estate by an enemy; or would not repay the evil suffered by a plundered province of Rome on the plunderers according to the rights of war? But these precepts of patience are to be observed in readiness of the heart, and that mercy, not to return evil for evil, must be always fulfilled by the will. Yet must we often use a merciful sharpness in dealing with the headstrong. And in this way, if the earthly commonwealth will keep the Christian commandments, even war will not be waged without good charities, to the establishing among the vanquished peaceful harmony of godliness and righteousness. For that victory is beneficial to him from whom it snatches licence to sin; since nothing is more unfortunate for sinners, than the good fortune of their sins, which nourishes an impunity that brings punishment after it, and an evil will is strengthened, as it were some internal enemy.

Because wealth is not ours but God's; God would have us stewards of His wealth, and not lords. Christ bids us lend but not on usury; for he who gives on such terms does not bestow his own, but takes of another; he looses from one chain to bind with many, and gives not for God's righteousness sake, but for his own gain. For money taken on usury is like the bite of an asp; as the asp's poison secretly consumes the limbs, so usury turns all our possessions into debt.
