Reply Obj. 3: A thing may be deemed gratuitous in two ways. In one way on the part of the deed itself, because, to wit, one is not bound to do it; in another way, on the part of the doer, because he does it of his own free will. Now a deed is rendered virtuous, praiseworthy and meritorious, chiefly according as it proceeds from the will. Wherefore although obedience be a duty, if one obey with a prompt will, one's merit is not for that reason diminished, especially before God, Who sees not only the outward deed, but also the inward will. _______________________
SECOND ARTICLE [II-II, Q, 104, Art. 2]
Whether Obedience Is a Special Virtue?
Objection 1: It seems that obedience is not a special virtue. For disobedience is contrary to obedience. But disobedience is a general sin, because Ambrose says (De Parad. viii) that "sin is to disobey the divine law." Therefore obedience is not a special virtue.
Obj. 2: Further, every special virtue is either theological or moral. But obedience is not a theological virtue, since it is not comprised under faith, hope or charity. Nor is it a moral virtue, since it does not hold the mean between excess and deficiency, for the more obedient one is the more is one praised. Therefore obedience is not a special virtue.
Obj. 3: Further, Gregory says (Moral. xxxv) that "obedience is the more meritorious and praiseworthy, the less it holds its own." But every special virtue is the more to be praised the more it holds its own, since virtue requires a man to exercise his will and choice, as stated in Ethic. ii, 4. Therefore obedience is not a special virtue.
Obj. 4: Further, virtues differ in species according to their objects. Now the object of obedience would seem to be the command of a superior, of which, apparently, there are as many kinds as there are degrees of superiority. Therefore obedience is a general virtue, comprising many special virtues.
On the contrary, obedience is reckoned by some to be a part of justice, as stated above (Q. 80).
I answer that, A special virtue is assigned to all good deeds that have a special reason of praise: for it belongs properly to virtue to render a deed good. Now obedience to a superior is due in accordance with the divinely established order of things, as shown above (A. 1), and therefore it is a good, since good consists in mode, species and order, as Augustine states (De Natura Boni iii) [*Cf. First Part, Q. 5, A. 5]. Again, this act has a special aspect of praiseworthiness by reason of its object. For while subjects have many obligations towards their superiors, this one, that they are bound to obey their commands, stands out as special among the rest. Wherefore obedience is a special virtue, and its specific object is a command tacit or express, because the superior's will, however it become known, is a tacit precept, and a man's obedience seems to be all the more prompt, forasmuch as by obeying he forestalls the express command as soon as he understands his superior's will.
Reply Obj. 1: Nothing prevents the one same material object from admitting two special aspects to which two special virtues correspond: thus a soldier, by defending his king's fortress, fulfils both an act of fortitude, by facing the danger of death for a good end, and an act of justice, by rendering due service to his lord. Accordingly the aspect of precept, which obedience considers, occurs in acts of all virtues, but not in all acts of virtue, since not all acts of virtue are a matter of precept, as stated above (I-II, Q. 96, A. 3). Moreover, certain things are sometimes a matter of precept, and pertain to no other virtue, such things for instance as are not evil except because they are forbidden. Wherefore, if obedience be taken in its proper sense, as considering formally and intentionally the aspect of precept, it will be a special virtue, and disobedience a special sin: because in this way it is requisite for obedience that one perform an act of justice or of some other virtue with the intention of fulfilling a precept; and for disobedience that one treat the precept with actual contempt. On the other hand, if obedience be taken in a wide sense for the performance of any action that may be a matter of precept, and disobedience for the omission of that action through any intention whatever, then obedience will be a general virtue, and disobedience a general sin.
