Rejection of the Use of Nuclear Weapons

During the immediate post war period, the Pope Pius XII, John XXIII, and the Second Vatican Council all spoke out clearly against the use of nuclear weapons and against the arms race.

When he traveled to Japan in February 1981, Pope John Paul II visited Hiroshima and Nagasaki as a 'pilgrim of peace'. At the Peace Memorial Park in Hiroshima he said:

To remember the past is to commit oneself to the future. To remember Hiroshima is to abhor nuclear war. To remember Hiroshima is to commit oneself to peace. To remember what the people of this city suffered is to renew our faith in man, in his capacity to do what is good, in his freedom to choose what is right, in his determination to turn disaster into a new beginning. In the face of the man-made calamity that every war is, one must affirm and reaffirm, again and again, that the waging of war is not inevitable or unchangeable. Humanity is not destined to self-destruction. Clashes of ideologies, aspirations and needs can and must be settled and resolved by means other than war and violence. Humanity owes it to itself to settle difference and conflicts by peaceful means. The great spectrum of problems facing the many peoples in varying stages of cultural, social, economic and political development gives rise to international tension and conflict. It is vital for humanity that these problems should be solved in accordance with ethical principles of equity and justice enshrined in meaningful agreements and institutions. The international community should thus give itself a system of law that will regulate international relations and maintain peace, just as the rule of law protects national order.

The Second Vatican Council document Gaudium et Spes stated that the development of new, scientific weapons called for "an evaluation of war with an entirely new attitude" (n 80). Two years earlier, in the encyclical Pacem in Terris, Pope John XXIII had noted as one of the 'signs of the times' the growing conviction that disputes between states could not be solved by recourse to arms (n 126). He felt that, historically, this conviction was based on the "terrible destructive force of modern arms", and that it was "... hardly possible to imagine that in the atomic era war could be used as an instrument of justice" (n 127).

Applying traditional Catholic teaching that the use of force - even in legitimate self defence - must also distinguish between combatants and non-combatants, the Second Vatican Council condemned any use of nuclear weapons as indiscriminate and therefore immoral:

"Any act of war aimed indiscriminately at the destruction of entire cities or extensive areas along with their population is a crime against God and man himself. It merits unhesitating condemnation." (GS No. 80)

 

Dangers of Deterrence

The strategy of nuclear deterrence was also criticized because it diverted intellectual and economic resources away from urgent development needs, and because it did not address the causes of war

"... the arms race in which so many countries are engaged is not a safe way to preserve a steady peace. Nor is the so-called balance resulting from this race a sure and authentic peace. Rather than being eliminated thereby, the causes of war threaten to grow gradually stronger.

...the arms race is an utterly treacherous trap for humanity, and one which injures the poor to an intolerable degree. It is much to be feared that if this race persists, it will eventually spawn all the lethal ruin whose path it is now making ready" (GS n 81)

The Church placed its hope not in a nuclear balance, but in the development of a competent international public authority, mutual trust and verifiable mutual disarmament (GS n 82). Unless and until such an authority was established, the right of states to use force in self defence after all peaceful means had been exhausted was recognized by the Second Vatican Council.

There has been much debate in theological circles over the morality of possessing nuclear weapons and the policy of deterrence. In 1982, Pope John Paul II made the judgement that:

"In current conditions 'deterrence' based on balance, certainly not as an end in itself but as a step on the way toward a progressive disarmament, may still be judged morally acceptable. Nonetheless in order to ensure peace, it is indispensable not to be satisfied with this minimum which is always susceptible to the real danger of explosion".

Message to the General Assembly of the United Nations
7 June 1982, n 8

 

Current Stance

Although the Church still acknowledges the theoretical possibility of a justified use of force under certain conditions (known collectively as the 'Just War Theory'), the practical judgments of the Church on the use of force in particular cases as they have arisen has become less and less accepting of the use of force. The Vatican's diplomatic efforts at the United Nations, and in other international fora, towards disarmament have intensified over the years:

"So long as it is taken as an end in itself, deterrence encourages the protagonists to ensure a constant superiority over one another, in ceaseless race of over-arming.

The concern of the Holy See mounts in seeing the non-proliferation regime, with the NPT as its cornerstone, in disarray. The old policies of nuclear deterrence, which prevailed in the Cold War, must lead now to concrete disarmament measures. The rule of law cannot countenance the continuation of doctrines that hold nuclear weapons as essential.

There can be no moral acceptance of military doctrines that embody the permanence of nuclear weapons. That is why Pope John Paul II has called for the banishment of all nuclear weapons through 'a workable system for negotiation, even of arbitration'. Those nuclear weapons states resisting negotiations should therefore be strongly urged to finally come to the negotiating table.

... my Delegation wishes to reaffirm its well-known position: nuclear weapons are incompatible with the peace we seek for the 21st century; they cannot be justified. These weapons are instruments of death and destruction. The preservation of the Non-Proliferation Treaty demands unequivocal action towards their elimination. Only when such a noble goal is attained can the international community be assured that nations are acting in 'good faith'.

... To keep developing weapon systems that can jeopardize the natural structure upon which all civilization rests seriously undermines the genuine quest of the family of nations to build a culture of peace for the present and future generations".
