Thomas Aquinas

“ In a sinner there are two things, his guilt and his nature. Accordingly we are bound to succor the sinner as to the maintenance of his nature, but not so as to abet his sin, for this would be to do evil rather than good. ”

“ Our Lord did not absolutely forbid us to invite our friends and kinsmen to eat with us, but to invite them so that they may invite us in return, since that would be an act not of charity but of cupidity. The case may occur, however, that one ought rather to invite strangers, on account of their greater want. For it must be understood that, other things being equal, one ought to succor those rather who are most closely connected with us. ”

“ Now to do good to some is to deal perversely: for instance if one were to do good to an enemy of the common weal, or if one were to do good to an excommunicated person, since, by doing so, he would be holding communion with him. Therefore, since beneficence is an act of charity, we ought not to do good to all. ”

“ It belongs to liberality to moderate this inward passion so as to avoid excessive desire and love for riches; for this makes a man more ready to part with his wealth. Hence, if a man makes some great gift, while yet desiring to keep it for himself, his is not a liberal giving. On the other hand, as regards the outward gift, the act of beneficence belongs in general to friendship or charity. Hence it does not detract from a man's friendship, if, through love, he give his friend something he would like to I keep for himself ”

“ Now no benefactor confers a benefit equal to that which a man receives from his parents: wherefore in paying back benefits received, we should give the first place to our parents before all others, unless, on the other side, there be such weightier motives, as need or some other circumstance, for instance the common good of the Church or state. In other cases we must take to account the connection and the benefit received ”

“ Further, vices are opposed to virtues. Now there are opposed to beneficence certain vices whereby a hurt is inflicted on our neighbor, for instance, rapine, theft and so forth. Therefore beneficence is a special virtue. ”

“ And if of two, one be more closely connected, and the other in greater want, it is not possible to decide, by any general rule, which of them we ought to help rather than the other, since there are various degrees of want as well as of connection: and the matter requires the judgment of a prudent man. ”

“ There is one which should be reckoned, not among the goods of the debtor, but rather as belonging to the person to whom it is due: for instance, a man may have another's goods, whether in money or in kind, either because he has stolen them, or because he has received them on loan or in deposit or in some other way. ”

“ In this case a man ought to pay what he owes, rather than benefit his connections out of it, unless perchance the case be so urgent that it would be lawful for him to take another's property in order to relieve the one who is in need. ”

“ And yet this may vary according to the various requirements of time, place, or matter in hand: because in certain cases one ought, for instance, to succor a stranger, in extreme necessity, rather than one's own father, if he is not in such urgent need. ”
