1168. For a neighbor who is in ordinary spiritual necessity charity requires that something be done (Ecclus, xvii. 12). (a) But it does not require the risk of life or of serious bodily loss, for the person in danger can easily and better help himself. Thus, it is not necessary that one should penetrate into the haunts of criminals and endanger one’s life, in order to drag away one who chooses to go to such places. (b) It does require that one be willing to undergo a slight bodily inconvenience or deprivation. Thus, an ordinary headache or the loss of a meal ought not to stop one from counselling another in order to keep him away from bad company.
1169. If only corporal good (life, health, liberty, etc.) is compared with corporal good of the same kind, then, as said above, one should prefer one’s own good to that of another. Thus, it is not lawful to offer oneself as substitute for a condemned criminal, or to put one’s family into bankruptcy to save another family from bankruptcy. But, if a neighbor’s corporal good is of a more important kind or is connected with higher goods, then one may sacrifice one’s own good for that of another.
(a) Thus, one may prefer a greater corporal good of a neighbor to a lesser corporal good of one’s own. Examples: One may weaken one’s health to save another’s life. One may give of one’s blood for a transfusion to assist another who is in danger of death.
(b) One may prefer an equal corporal good of a neighbor to an equal corporal good of one’s own, if the common good requires this; for the good of all is preferable to that of an individual. Thus, one may expose oneself to the peril of death in order to protect a public person whose life is very important to the nation. Thus, policemen and firemen, soldiers and sailors, are daily imperilling their own safety for the safety of the public.
(c) One may prefer an equal corporal good of another, who is only a private individual, to one’s own equal good, if the intention is to practise virtue, to assist a person in need, or to give edification. At least, it is more probable that this is lawful, for the good of virtue is a higher good than the good of the body, and the Fathers praise holy men who sold themselves into slavery, or who gave themselves as hostages to barbarians, for the liberation of captives; and they hold up for admiration Damon and Pythias, each of whom was ready to die for the other. Hence, it is not against the charity owed to self to jump into a river and risk one’s life in order to rescue a drowning person, for heroic charity is a hotter adornment to self than mere, ordinary charity. Similarly, if two explorers in a wilderness have only enough provisions for one to reach civilization, one of them may surrender his rations to the other, that both may not be lost.
1170. There are two exceptions to the rules just given: (a) A person should not risk his life for another’s life, if he thereby endangers his own salvation (e.g., if he is in a state of sin and cannot reconcile himself to God). But this case is theoretical, for it is admitted that one who makes the supreme sacrifice of giving his life with a virtuous intention, has not only charity, but the perfection of charity (John, xv. 13), which will certainly purify him even from a multitude of sins. (b) One should not risk one’s life for the life of another, if a third party has a higher claim on him. Thus, a married man, who has a dependent wife and children, may not throw away his life for the sake of a friend.
1171. The order of charity between different neighbors is as follows: (a) as to good in general (e.g., the attainment of salvation), we should love all neighbors alike, for we should desire salvation for all; (b) as to good in particular (e.g., the degree of beatitude), we should love some more than others. Thus, we should desire a higher degree of glory for the Blessed Virgin than for the Saints.
1172. The reasons for loving one neighbor more than another can be reduced to two. (a) One neighbor may be nearer to God than another, and hence more deserving of love—for example, a saintly acquaintance may be nearer to God than a sinful relative. (b) One neighbor may be nearer to ourselves on account of relationship by blood or marriage, friendship, civil or professional ties, etc. Thus, a cousin is nearer by nature to his cousin than another person who is not a relative.
1173. The order of charity as between those nearer to God and those nearer to self is as follows:
(a) Objectively, we should esteem more those who are better, and desire for them that higher degree of God’s favor which belongs to their merits. But we may desire for those nearer to ourselves that they will finally surpass in holiness those now better than they are, and thus attain to a greater beatitude. Moreover, while we prefer in one respect (i.e., that of holiness) a saintly person, who is a stranger, we prefer in many respects (e.g., on account of relationship, friendship, gratitude) another who is less holy.
