OF WAR (In Four Articles)
We must now consider war, under which head there are four points of inquiry:
(1) Whether some kind of war is lawful?
(2) Whether it is lawful for clerics to fight?
(3) Whether it is lawful for belligerents to lay ambushes?
(4) Whether it is lawful to fight on holy days?

FIRST ARTICLE [II-II, Q. 40, Art. 1]
Whether It Is Always Sinful to Wage War?
Objection 1: It would seem that it is always sinful to wage war.
Because punishment is not inflicted except for sin. Now those who wage war are threatened by Our Lord with punishment, according to Matt. 26:52: "All that take the sword shall perish with the sword."
Therefore all wars are unlawful.
Obj. 2: Further, whatever is contrary to a Divine precept is a sin.
But war is contrary to a Divine precept, for it is written (Matt.
5:39): "But I say to you not to resist evil"; and (Rom. 12:19): "Not revenging yourselves, my dearly beloved, but give place unto wrath."
Therefore war is always sinful.
Obj. 3: Further, nothing, except sin, is contrary to an act of virtue. But war is contrary to peace. Therefore war is always a sin.
Obj. 4: Further, the exercise of a lawful thing is itself lawful, as is evident in scientific exercises. But warlike exercises which take place in tournaments are forbidden by the Church, since those who are slain in these trials are deprived of ecclesiastical burial.
Therefore it seems that war is a sin in itself.
_On the contrary,_ Augustine says in a sermon on the son of the centurion [*Ep. ad Marcel. cx.x.xviii]: "If the Christian Religion forbade war altogether, those who sought salutary advice in the Gospel would rather have been counselled to cast aside their arms, and to give up soldiering altogether. _On the contrary,_ they were told: "Do violence to no man ... and be content with your pay"
[*Luke 3:14]. If he commanded them to be content with their pay, he did not forbid soldiering."
_I answer that,_ In order for a war to be just, three things are necessary. First, the authority of the sovereign by whose command the war is to be waged. For it is not the business of a private individual to declare war, because he can seek for redress of his rights from the tribunal of his superior. Moreover it is not the business of a private individual to summon together the people, which has to be done in wartime. And as the care of the common weal is committed to those who are in authority, it is their business to watch over the common weal of the city, kingdom or province subject to them. And just as it is lawful for them to have recourse to the sword in defending that common weal against internal disturbances, when they punish evil-doers, according to the words of the Apostle (Rom. 13:4): "He beareth not the sword in vain: for he is G.o.d"s minister, an avenger to execute wrath upon him that doth evil"; so too, it is their business to have recourse to the sword of war in defending the common weal against external enemies. Hence it is said to those who are in authority (Ps. 81:4): "Rescue the poor: and deliver the needy out of the hand of the sinner"; and for this reason Augustine says (Contra Faust. xxii, 75): "The natural order conducive to peace among mortals demands that the power to declare and counsel war should be in the hands of those who hold the supreme authority."
Secondly, a just cause is required, namely that those who are attacked, should be attacked because they deserve it on account of some fault. Wherefore Augustine says (QQ. in Hept., qu. x, super Jos.): "A just war is wont to be described as one that avenges wrongs, when a nation or state has to be punished, for refusing to make amends for the wrongs inflicted by its subjects, or to restore what it has seized unjustly."
Thirdly, it is necessary that the belligerents should have a rightful intention, so that they intend the advancement of good, or the avoidance of evil. Hence Augustine says (De Verb. Dom. [*The words quoted are to be found not in St. Augustine"s works, but Can. Apud.
Caus. xxiii, qu. 1]): "True religion looks upon as peaceful those wars that are waged not for motives of aggrandizement, or cruelty, but with the object of securing peace, of punishing evil-doers, and of uplifting the good." For it may happen that the war is declared by the legitimate authority, and for a just cause, and yet be rendered unlawful through a wicked intention. Hence Augustine says (Contra Faust. xxii, 74): "The pa.s.sion for inflicting harm, the cruel thirst for vengeance, an unpacific and relentless spirit, the fever of revolt, the l.u.s.t of power, and such like things, all these are rightly condemned in war."
Reply Obj. 1: As Augustine says (Contra Faust. xxii, 70): "To take the sword is to arm oneself in order to take the life of anyone, without the command or permission of superior or lawful authority."
On the other hand, to have recourse to the sword (as a private person) by the authority of the sovereign or judge, or (as a public person) through zeal for justice, and by the authority, so to speak, of G.o.d, is not to "take the sword," but to use it as commissioned by another, wherefore it does not deserve punishment. And yet even those who make sinful use of the sword are not always slain with the sword, yet they always perish with their own sword, because, unless they repent, they are punished eternally for their sinful use of the sword.
Reply Obj. 2: Such like precepts, as Augustine observes (De Serm.
Dom. in Monte i, 19), should always be borne in readiness of mind, so that we be ready to obey them, and, if necessary, to refrain from resistance or self-defense. Nevertheless it is necessary sometimes for a man to act otherwise for the common good, or for the good of those with whom he is fighting. Hence Augustine says (Ep. ad Marcellin. cx.x.xviii): "Those whom we have to punish with a kindly severity, it is necessary to handle in many ways against their will.
For when we are stripping a man of the lawlessness of sin, it is good for him to be vanquished, since nothing is more hopeless than the happiness of sinners, whence arises a guilty impunity, and an evil will, like an internal enemy."
Reply Obj. 3: Those who wage war justly aim at peace, and so they are not opposed to peace, except to the evil peace, which Our Lord "came not to send upon earth" (Matt. 10:34). Hence Augustine says (Ep. ad Bonif. clx.x.xix): "We do not seek peace in order to be at war, but we go to war that we may have peace. Be peaceful, therefore, in warring, so that you may vanquish those whom you war against, and bring them to the prosperity of peace."
Reply Obj. 4: Manly exercises in warlike feats of arms are not all forbidden, but those which are inordinate and perilous, and end in slaying or plundering. In olden times warlike exercises presented no such danger, and hence they were called "exercises of arms" or "bloodless wars," as Jerome states in an epistle [*Reference incorrect: cf. Veget., De Re Milit. i].

SECOND ARTICLE [II-II, Q. 40, Art. 2]
Whether It Is Lawful for Clerics and Bishops to Fight?
Objection 1: It would seem lawful for clerics and bishops to fight.
For, as stated above (A. 1), wars are lawful and just in so far as they protect the poor and the entire common weal from suffering at the hands of the foe. Now this seems to be above all the duty of prelates, for Gregory says (Hom. in Ev. xiv): "The wolf comes upon the sheep, when any unjust and rapacious man oppresses those who are faithful and humble. But he who was thought to be the shepherd, and was not, leaveth the sheep, and flieth, for he fears lest the wolf hurt him, and dares not stand up against his injustice." Therefore it is lawful for prelates and clerics to fight.
Obj. 2: Further, Pope Leo IV writes (xxiii, qu. 8, can. Igitur): "As untoward tidings had frequently come from the Saracen side, some said that the Saracens would come to the port of Rome secretly and covertly; for which reason we commanded our people to gather together, and ordered them to go down to the seash.o.r.e." Therefore it is lawful for bishops to fight.
Obj. 3: Further, apparently, it comes to the same whether a man does a thing himself, or consents to its being done by another, according to Rom. 1:32: "They who do such things, are worthy of death, and not only they that do them, but they also that consent to them that do them." Now those, above all, seem to consent to a thing, who induce others to do it. But it is lawful for bishops and clerics to induce others to fight: for it is written (xxiii, qu. 8, can. Hortatu) that Charles went to war with the Lombards at the instance and entreaty of Adrian, bishop of Rome. Therefore they also are allowed to fight.
Obj. 4: Further, whatever is right and meritorious in itself, is lawful for prelates and clerics. Now it is sometimes right and meritorious to make war, for it is written (xxiii, qu. 8, can. Omni timore) that if "a man die for the true faith, or to save his country, or in defense of Christians, G.o.d will give him a heavenly reward." Therefore it is lawful for bishops and clerics to fight.
_On the contrary,_ It was said to Peter as representing bishops and clerics (Matt. 16:52): "Put up again thy sword into the scabbard [Vulg.: "its place"] [*"Scabbard" is the reading in John 18:11]."
Therefore it is not lawful for them to fight.
_I answer that,_ Several things are requisite for the good of a human society: and a number of things are done better and quicker by a number of persons than by one, as the Philosopher observes (Polit. i, 1), while certain occupations are so inconsistent with one another, that they cannot be fittingly exercised at the same time; wherefore those who are deputed to important duties are forbidden to occupy themselves with things of small importance. Thus according to human laws, soldiers who are deputed to warlike pursuits are forbidden to engage in commerce [*Cod. xii, 35, De Re Milit.].
Now warlike pursuits are altogether incompatible with the duties of a bishop and a cleric, for two reasons. The first reason is a general one, because, to wit, warlike pursuits are full of unrest, so that they hinder the mind very much from the contemplation of Divine things, the praise of G.o.d, and prayers for the people, which belong to the duties of a cleric. Wherefore just as commercial enterprises are forbidden to clerics, because they unsettle the mind too much, so too are warlike pursuits, according to 2 Tim. 2:4: "No man being a soldier to G.o.d, entangleth himself with secular business." The second reason is a special one, because, to wit, all the clerical Orders are directed to the ministry of the altar, on which the Pa.s.sion of Christ is represented sacramentally, according to 1 Cor. 11:26: "As often as you shall eat this bread, and drink the chalice, you shall show the death of the Lord, until He come." Wherefore it is unbecoming for them to slay or shed blood, and it is more fitting that they should be ready to shed their own blood for Christ, so as to imitate in deed what they portray in their ministry. For this reason it has been decreed that those who shed blood, even without sin, become irregular. Now no man who has a certain duty to perform, can lawfully do that which renders him unfit for that duty. Wherefore it is altogether unlawful for clerics to fight, because war is directed to the shedding of blood.
Reply Obj. 1: Prelates ought to withstand not only the wolf who brings spiritual death upon the flock, but also the pillager and the oppressor who work bodily harm; not, however, by having recourse themselves to material arms, but by means of spiritual weapons, according to the saying of the Apostle (2 Cor. 10:4): "The weapons of our warfare are not carnal, but mighty through G.o.d." Such are salutary warnings, devout prayers, and, for those who are obstinate, the sentence of excommunication.
Reply Obj. 2: Prelates and clerics may, by the authority of their superiors, take part in wars, not indeed by taking up arms themselves, but by affording spiritual help to those who fight justly, by exhorting and absolving them, and by other like spiritual helps. Thus in the Old Testament (Joshua 6:4) the priests were commanded to sound the sacred trumpets in the battle. It was for this purpose that bishops or clerics were first allowed to go to the front: and it is an abuse of this permission, if any of them take up arms themselves.
Reply Obj. 3: As stated above (Q. 23, A. 4, ad 2) every power, art or virtue that regards the end, has to dispose that which is directed to the end. Now, among the faithful, carnal wars should be considered as having for their end the Divine spiritual good to which clerics are deputed. Wherefore it is the duty of clerics to dispose and counsel other men to engage in just wars. For they are forbidden to take up arms, not as though it were a sin, but because such an occupation is unbecoming their personality.
Reply Obj. 4: Although it is meritorious to wage a just war, nevertheless it is rendered unlawful for clerics, by reason of their being deputed to works more meritorious still. Thus the marriage act may be meritorious; and yet it becomes reprehensible in those who have vowed virginity, because they are bound to a yet greater good.

THIRD ARTICLE [II-II, Q., 40, Art. 3]
Whether It Is Lawful to Lay Ambushes in War?
Objection 1: It would seem that it is unlawful to lay ambushes in war. For it is written (Deut. 16:20): "Thou shalt follow justly after that which is just." But ambushes, since they are a kind of deception, seem to pertain to injustice. Therefore it is unlawful to lay ambushes even in a just war.
Obj. 2: Further, ambushes and deception seem to be opposed to faithfulness even as lies are. But since we are bound to keep faith with all men, it is wrong to lie to anyone, as Augustine states (Contra Mend. xv). Therefore, as one is bound to keep faith with one"s enemy, as Augustine states (Ep. ad Bonif. clx.x.xix), it seems that it is unlawful to lay ambushes for one"s enemies.
Obj. 3: Further, it is written (Matt. 7:12): "Whatsoever you would that men should do to you, do you also to them": and we ought to observe this in all our dealings with our neighbor. Now our enemy is our neighbor. Therefore, since no man wishes ambushes or deceptions to be prepared for himself, it seems that no one ought to carry on war by laying ambushes.
_On the contrary,_ Augustine says (QQ. in Hept. qu. x super Jos): "Provided the war be just, it is no concern of justice whether it be carried on openly or by ambushes": and he proves this by the authority of the Lord, Who commanded Joshua to lay ambushes for the city of Hai (Joshua 8:2).
_I answer that,_ The object of laying ambushes is in order to deceive the enemy. Now a man may be deceived by another"s word or deed in two ways. First, through being told something false, or through the breaking of a promise, and this is always unlawful. No one ought to deceive the enemy in this way, for there are certain "rights of war and covenants, which ought to be observed even among enemies," as Ambrose states (De Officiis i).
Secondly, a man may be deceived by what we say or do, because we do not declare our purpose or meaning to him. Now we are not always bound to do this, since even in the Sacred Doctrine many things have to be concealed, especially from unbelievers, lest they deride it, according to Matt. 7:6: "Give not that which is holy, to dogs."
Wherefore much more ought the plan of campaign to be hidden from the enemy. For this reason among other things that a soldier has to learn is the art of concealing his purpose lest it come to the enemy"s knowledge, as stated in the Book on _Strategy_ [*Stratagematum i, 1]
by Frontinus. Such like concealment is what is meant by an ambush which may be lawfully employed in a just war.
