First, on the part of God, to Whom man is the more closely united, as he is more virtuous or more sacred to God: so that an injury inflicted on such a person redounds on to God according to Zech. 2:8: “He that toucheth you, toucheth the apple of My eye.” Wherefore a sin is the more grievous, according as it is committed against a person more closely united to God by reason of personal sanctity, or official station. On the part of man himself, it is evident that he sins all the more grievously, according as the person against whom he sins, is more united to him, either through natural affinity or kindness received or any other bond; because he seems to sin against himself rather than the other, and, for this very reason, sins all the more grievously, according to Ecclus. 14:5: “He that is evil to himself, to whom will he be good?” On the part of his neighbor, a man sins the more grievously, according as his sin affects more persons: so that a sin committed against a public personage, e.g. a sovereign prince who stands in the place of the whole people, is more grievous than a sin committed against a private person; hence it is expressly prohibited (Ex. 22:28): “The prince of thy people thou shalt not curse.” In like manner it would seem that an injury done to a person of prominence, is all the more grave, on account of the scandal and the disturbance it would cause among many people.
Reply Obj. 1: He who inflicts an injury on a virtuous person, so far as he is concerned, disturbs him internally and externally; but that the latter is not disturbed internally is due to his goodness, which does not extenuate the sin of the injurer.
Reply Obj. 2: The injury which a man inflicts on himself in those things which are subject to the dominion of his will, for instance his possessions, is less sinful than if it were inflicted on another, because he does it of his own will; but in those things that are not subject to the dominion of his will, such as natural and spiritual goods, it is a graver sin to inflict an injury on oneself: for it is more grievous for a man to kill himself than another. Since, however, things belonging to our neighbor are not subject to the dominion of our will, the argument fails to prove, in respect of injuries done to such like things, that it is less grievous to sin in their regard, unless indeed our neighbor be willing, or give his approval.
Reply Obj. 3: There is no respect for persons if God punishes more severely those who sin against a person of higher rank; for this is done because such an injury redounds to the harm of many. ________________________
