Dear Tom:
To boycott all war, that is to be a total pacifist, is permitted to a Catholic if their conscience leads them into that direction. To be a total pacifist is to object to all war no matter what the causes of that war, even a "just war." If war were to come to the shores of the United States you could not defend this country as a soldier, as an underground guerrilla or resistance fighter, or as a private citizen.
But, as it is with any subject, one must have an informed conscience.
Here is what the Church says from the Catechism about defending oneself against a deadly attack and about war:
Legitimate defense
2263 The legitimate defense of persons and societies is not an exception to the prohibition against the murder of the innocent that constitutes intentional killing. "The act of self-defense can have a double effect: the preservation of one's own life; and the killing of the aggressor. . . . The one is intended, the other is not."
2264 Love toward oneself remains a fundamental principle of morality. Therefore it is legitimate to insist on respect for one's own right to life. Someone who defends his life is not guilty of murder even if he is forced to deal his aggressor a lethal blow:
- If a man in self-defense uses more than necessary violence, it will be unlawful: whereas if he repels force with moderation, his defense will be lawful. . . . Nor is it necessary for salvation that a man omit the act of moderate self-defense to avoid killing the other man, since one is bound to take more care of one's own life than of another's.
2265 Legitimate defense can be not only a right but a grave duty for one who is responsible for the lives of others. The defense of the common good requires that an unjust aggressor be rendered unable to cause harm. For this reason, those who legitimately hold authority also have the right to use arms to repel aggressors against the civil community entrusted to their responsibility.
2266 The efforts of the state to curb the spread of behavior harmful to people's rights and to the basic rules of civil society correspond to the requirement of safeguarding the common good. Legitimate public authority has the right and duty to inflict punishment proportionate to the gravity of the offense. Punishment has the primary aim of redressing the disorder introduced by the offense. When it is willingly accepted by the guilty party, it assumes the value of expiation. Punishment then, in addition to defending public order and protecting people's safety, has a medicinal purpose: as far as possible, it must contribute to the correction of the guilty party.
2267 Assuming that the guilty party's identity and responsibility have been fully determined, the traditional teaching of the Church does not exclude recourse to the death penalty, if this is the only possible way of effectively defending human lives against the unjust aggressor.
If, however, non-lethal means are sufficient to defend and protect people's safety from the aggressor, authority will limit itself to such means, as these are more in keeping with the concrete conditions of the common good and more in conformity to the dignity of the human person.
Today, in fact, as a consequence of the possibilities which the state has for effectively preventing crime, by rendering one who has committed an offense incapable of doing harm - without definitely taking away from him the possibility of redeeming himself - the cases in which the execution of the offender is an absolute necessity "are very rare, if not practically nonexistent."
Concerning War, Just War theory, and Conscientious Objection to War:
2304 Respect for and development of human life require peace. Peace is not merely the absence of war, and it is not limited to maintaining a balance of powers between adversaries. Peace cannot be attained on earth without safeguarding the goods of persons, free communication among men, respect for the dignity of persons and peoples, and the assiduous practice of fraternity. Peace is "the tranquillity of order." Peace is the work of justice and the effect of charity.
2305 Earthly peace is the image and fruit of the peace of Christ, the messianic "Prince of Peace." By the blood of his Cross, "in his own person he killed the hostility," he reconciled men with God and made his Church the sacrament of the unity of the human race and of its union with God. "He is our peace." He has declared: "Blessed are the peacemakers."
2306 Those who renounce violence and bloodshed and, in order to safeguard human rights, make use of those means of defense available to the weakest, bear witness to evangelical charity, provided they do so without harming the rights and obligations of other men and societies. They bear legitimate witness to the gravity of the physical and moral risks of recourse to violence, with all its destruction and death.
Avoiding war
2307 The fifth commandment forbids the intentional destruction of human life. Because of the evils and injustices that accompany all war, the Church insistently urges everyone to prayer and to action so that the divine Goodness may free us from the ancient bondage of war.
2308 All citizens and all governments are obliged to work for the avoidance of war.
However, "as long as the danger of war persists and there is no international authority with the necessary competence and power, governments cannot be denied the right of lawful self-defense, once all peace efforts have failed."
2309 The strict conditions for legitimate defense by military force require rigorous consideration. The gravity of such a decision makes it subject to rigorous conditions of moral legitimacy. At one and the same time:
- the damage inflicted by the aggressor on the nation or community of nations must be lasting, grave, and certain;
- all other means of putting an end to it must have been shown to be impractical or ineffective;
- there must be serious prospects of success;
- the use of arms must not produce evils and disorders graver than the evil to be eliminated. The power of modem means of destruction weighs very heavily in evaluating this condition.
These are the traditional elements enumerated in what is called the "just war" doctrine.
The evaluation of these conditions for moral legitimacy belongs to the prudential judgment of those who have responsibility for the common good.
2310 Public authorities, in this case, have the right and duty to impose on citizens the obligations necessary for national defense.
Those who are sworn to serve their country in the armed forces are servants of the security and freedom of nations. If they carry out their duty honorably, they truly contribute to the common good of the nation and the maintenance of peace.
2311 Public authorities should make equitable provision for those who for reasons of conscience refuse to bear arms; these are nonetheless obliged to serve the human community in some other way.
2312 The Church and human reason both assert the permanent validity of the moral law during armed conflict. "The mere fact that war has regrettably broken out does not mean that everything becomes licit between the warring parties."
2313 Non-combatants, wounded soldiers, and prisoners must be respected and treated humanely.
Actions deliberately contrary to the law of nations and to its universal principles are crimes, as are the orders that command such actions. Blind obedience does not suffice to excuse those who carry them out. Thus the extermination of a people, nation, or ethnic minority must be condemned as a mortal sin. One is morally bound to resist orders that command genocide.
2314 "Every act of war directed to the indiscriminate destruction of whole cities or vast areas with their inhabitants is a crime against God and man, which merits firm and unequivocal condemnation."A danger of modern warfare is that it provides the opportunity to those who possess modern scientific weapons especially atomic, biological, or chemical weapons - to commit such crimes.
2315 The accumulation of arms strikes many as a paradoxically suitable way of deterring potential adversaries from war. They see it as the most effective means of ensuring peace among nations. This method of deterrence gives rise to strong moral reservations. The arms race does not ensure peace. Far from eliminating the causes of war, it risks aggravating them. Spending enormous sums to produce ever new types of weapons impedes efforts to aid needy populations; it thwarts the development of peoples. Over-armament multiplies reasons for conflict and increases the danger of escalation.
2316 The production and the sale of arms affect the common good of nations and of the international community. Hence public authorities have the right and duty to regulate them. The short-term pursuit of private or collective interests cannot legitimate undertakings that promote violence and conflict among nations and compromise the international juridical order.
2317 Injustice, excessive economic or social inequalities, envy, distrust, and pride raging among men and nations constantly threaten peace and cause wars. Everything done to overcome these disorders contributes to building up peace and avoiding war:
-
Insofar as men are sinners, the threat of war hangs over them and will so continue until Christ comes again; but insofar as they can vanquish sin by coming together in charity, violence itself will be vanquished and these words will be fulfilled: "they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war any more."
I am reminded of the movie "The Mission." Two missionary priests in 18th Century South America struggled with the issue of violence. The people they served were under attack. Toward the end of the movie the two priests took two different actions in the face of the soldiers killing their people. The movie correctly did not promote one action over the other as both actions are permitted according to one's conscience.
One priest, Father Gabriel (played by Jeremy Irons), processed through the battlefield holding up the Eucharist in a monstrance.
The other priest, a convert and formerly a mercenary and slaver, Rodrigo Mendoza (played by Robert De Niro), took up arms to protect the people.
Just as Father Mendoza falls mortally wounded, he sees Father Gabriel, who is singing with the children and holding up the Eucharist, fall and die. The women and children are also shot down.
The movie ends with the audience pondering which priest, who both gave their lives for the people, did the right thing—to take up arms, or to process through the battleground singing with the Eucharist.
If you have not seen this 1986 movie, you must see it.
Before I took vows I had no problem serving my country, which I did during the last year of Vietnam. I had no problem with the need to kill others to defend my country. Since I am now a brother I struggle with this.
If I were confronted with death squads, like those in El Salvador in the 1980s, would I pick up a weapon to protect the women and children of the village? I do not know.
I was almost in a situation like that as a civilian, not as a soldier, when I was part of an independent team of TV and still photographers planning to go to Honduras to record on film a forced march of refugees that might have been as terrible as the Bataan Death march during WWII. Obviously, the government would not want this documented. This was a very dangerous trip.
We made all the plans, assembled the team, but then did not raise the needed funds for the trip. Thus, that test as a civilian in wartime "harms way" never came. If it came to the point that I needed to stop being the photographer and save the lives of women and children, I think I would have tried to save the lives of the people. I guess that makes me a terrible photojournalist who is always to stay neutral and "get the shot." Would I have protected the refugees by killing the soldiers? I do not know. One can never know until it happens. My inclination is yes, but now as a brother, i really do not know. All I can do is to ask God to give me the strength to do what He wants me to do should I be in such a situation. There are worse things than death. Non-Christians do not understand that much.
Martin Luther King Jr. once said, "If a man has not found something worth dying for, he is not fit to live." I have lived my entire life according to that Maxim.
In the end, you (we all) must decide according to our informed conscience whether or not we will go to war.
God Bless,
Bro. Ignatius Mary
