SECOND ARTICLE [II-II, Q. 33, Art. 2]
Whether Fraternal Correction Is a Matter of Precept?
Objection 1: It would seem that fraternal correction is not a matter of precept. For nothing impossible is a matter of precept, according to the saying of Jerome [*Pelagius, Expos. Symb. ad Damas]: "Accursed be he who says that God has commanded anything impossible." Now it is written (Eccles. 7:14): "Consider the works of God, that no man can correct whom He hath despised." Therefore fraternal correction is not a matter of precept.
Obj. 2: Further, all the precepts of the Divine Law are reduced to the precepts of the Decalogue. But fraternal correction does not come under any precept of the Decalogue. Therefore it is not a matter of precept.
Obj. 3: Further, the omission of a Divine precept is a mortal sin, which has no place in a holy man. Yet holy and spiritual men are found to omit fraternal correction: since Augustine says (De Civ. Dei i, 9): "Not only those of low degree, but also those of high position, refrain from reproving others, moved by a guilty cupidity, not by the claims of charity." Therefore fraternal correction is not a matter of precept.
Obj. 4: Further, whatever is a matter of precept is something due. If, therefore, fraternal correction is a matter of precept, it is due to our brethren that we correct them when they sin. Now when a man owes anyone a material due, such as the payment of a sum of money, he must not be content that his creditor come to him, but he should seek him out, that he may pay him his due. Hence we should have to go seeking for those who need correction, in order that we might correct them; which appears to be inconvenient, both on account of the great number of sinners, for whose correction one man could not suffice, and because religious would have to leave the cloister in order to reprove men, which would be unbecoming. Therefore fraternal correction is not a matter of precept.
On the contrary, Augustine says (De Verb. Dom. xvi, 4): "You become worse than the sinner if you fail to correct him." But this would not be so unless, by this neglect, one omitted to observe some precept. Therefore fraternal correction is a matter of precept.
I answer that, Fraternal correction is a matter of precept. We must observe, however, that while the negative precepts of the Law forbid sinful acts, the positive precepts inculcate acts of virtue. Now sinful acts are evil in themselves, and cannot become good, no matter how, or when, or where, they are done, because of their very nature they are connected with an evil end, as stated in Ethic. ii, 6: wherefore negative precepts bind always and for all times. On the other hand, acts of virtue must not be done anyhow, but by observing the due circumstances, which are requisite in order that an act be virtuous; namely, that it be done where, when, and how it ought to be done. And since the disposition of whatever is directed to the end depends on the formal aspect of the end, the chief of these circumstances of a virtuous act is this aspect of the end, which in this case is the good of virtue. If therefore such a circumstance be omitted from a virtuous act, as entirely takes away the good of virtue, such an act is contrary to a precept. If, however, the circumstance omitted from a virtuous act be such as not to destroy the virtue altogether, though it does not perfectly attain the good of virtue, it is not against a precept. Hence the Philosopher (Ethic. ii, 9) says that if we depart but little from the mean, it is not contrary to the virtue, whereas if we depart much from the mean virtue is destroyed in its act. Now fraternal correction is directed to a brother's amendment: so that it is a matter of precept, in so far as it is necessary for that end, but not so as we have to correct our erring brother at all places and times.
Reply Obj. 1: In all good deeds man's action is not efficacious without the Divine assistance: and yet man must do what is in his power. Hence Augustine says (De Correp. et Gratia xv): "Since we ignore who is predestined and who is not, charity should so guide our feelings, that we wish all to be saved." Consequently we ought to do our brethren the kindness of correcting them, with the hope of God's help.
Reply Obj. 2: As stated above (Q. 32, A. 5, ad 4), all the precepts about rendering service to our neighbor are reduced to the precept about the honor due to parents.
