Jeremiah 4:19

 

My soul, my soul! I am in anguish! Oh, my heart!

My heart is pounding in me;

I cannot be silent,

Because you have heard, O my soul,

The sound of the trumpet,

The alarm of war.

St. Matthew 24:3-8

As he sat on the Mount of Olives, the disciples came to him privately, saying, “Tell us, when will this be, and what will be the sign of your coming and of the close of the age?” And Jesus answered them, “Take heed that no one leads you astray. For many will come in my name, saying, ‘I am the Christ,’ and they will lead many astray. And you will hear of wars and rumors of wars; see that you are not alarmed; for this must take place, but the end is not yet. For nation will rise against nation, and kingdom against kingdom, and there will be famines and earthquakes in various places: all this is but the beginning of the sufferings.

Romans 7:23

But I see a different law in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin which is in my members.

Ephesians 6:10-20

Finally, be strong in the Lord and in the strength of his might. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For we are not contending against flesh and blood, but against the principalities, against the powers, against the world rulers of this present darkness, against the spiritual hosts of wickedness in the heavenly places. Therefore take the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having girded your loins with truth, and having put on the breastplate of righteousness, and having shod your feet with the equipment of the gospel of peace; above all taking the shield of faith, with which you can quench all the flaming darts of the evil one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God. Pray at all times in the Spirit, with all prayer and supplication. To that end keep alert with all perseverance, making supplication for all the saints, and also for me, that utterance may be given me in opening my mouth boldly to proclaim the mystery of the gospel, for which I am an ambassador in chains; that I may declare it boldly, as I ought to speak.

1 Corinthians 14:8

For if the trumpet give an uncertain sound, who shall prepare himself to the battle?

James 4:1

What causes wars, and what causes fightings among you? Is it not your passions that are at war in your members?

Revelation 21:5-8

And he who sat upon the throne said, “Behold, I make all things new.” Also he said, “Write this, for these words are trustworthy and true.” And he said to me, “It is done! I am the Alpha and the Omega, the beginning and the end. To the thirsty I will give water without price from the fountain of the water of life. He who conquers shall have this heritage, and I will be his God and he shall be my son. But as for the cowardly, the faithless, the polluted, as for murderers, fornicators, sorcerers, idolaters, and all liars, their lot shall be in the lake that burns with fire and brimstone, which is the second death.”

The Catechism of the Catholic Church

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 modern 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.

Compendium of the Social Doctrine of the Church

Citizens are not obligated in conscience to follow the prescriptions of civil authorities if their precepts are contrary to the demands of the moral order, to the fundamental rights of persons or to the teachings of the Gospel. Unjust laws pose dramatic problems of conscience for morally upright people: when they are called to cooperate in morally evil acts they must refuse. Besides being a moral duty, such a refusal is also a basic human right which, precisely as such, civil law itself is obliged to recognize and protect. 'Those who have recourse to conscientious objection must be protected not only from legal penalties but also from any negative effects on the legal, disciplinary, financial and professional plane.'

It is a grave duty of conscience not to cooperate, not even formally, in practices which, although permitted by civil legislation, are contrary to the Law of God. Such cooperation in fact can never be justified, not by invoking respect for the freedom of others nor by appealing to the fact that it is foreseen and required by civil law. No one can escape the moral responsibility for actions taken, and all will be judged by God himself based on this responsibility (cf. Rom 2:6; 14:12). (Compendium, No. 399)

The right of conscientious objection is not the right of resistance, and the two should be carefully distinguished. Moreover, resistance which can be expressed in "many different concrete ways" should be distinguished from the last and desperate recourse of "armed resistance."

The right to resist an oppressive law or an oppressive government is one that is found in the natural law. It is a right which precedes a government, and so is one that is inalienable.  Resistance generally is something to be avoided, and it is justified only if there is a "serious" infringement or "repeated" and chronic infringements of the natural moral law, a fundamental human right, or a Gospel precept.

Recognizing that natural law is the basis for and places limits on positive law means admitting that it is legitimate to resist authority should it violate in a serious or repeated manner the essential principles of natural law. Saint Thomas Aquinas writes that 'one is obliged to obey . . . insofar as it is required by the order of justice.' Natural law is therefore the basis of the right to resistance.  (Compendium, No. 400)

The right of resistance is not one that necessarily has the overthrow of government in mind. There may be many ways in which resistance may be expressed, and there may be many ends which resistance may have in mind:

There can be many different concrete ways this right may be exercised; there are also many different ends that may be pursued. Resistance to authority is meant to attest to the validity of a different way of looking at things, whether the intent is to achieve partial change, for example, modifying certain laws, or to fight for a radical change in the situation.  (Compendium, No. 400)

Resistance in the sense of armed resistance is something which is a last resort. The Church has identified five conditions all of which must be met before armed resistance is morally justified: "1) there is certain, grave and prolonged violation of fundamental rights, 2) all other means of redress have been exhausted, 3) such resistance will not provoke worse disorders, 4) there is well-founded hope of success; and 5) it is impossible reasonably to foresee any better solution. (Compendium, No. 401)
