In October 1965, during the meeting of the Second Vatican Council, Pope Paul VI paid a visit to the United Nations. The then Secretary General of the United Nations had invited the Holy Father to speak to the General Assembly in marking the twentieth anniversary of the organisation. Paul VI himself described this visit as a moment "bearing the imprint of a unique greatness", both for himself and for the United Nations. The full English text of Pope Paul's address can be found here at the Vatican website; the United Nations website carries a radio report, in English, of his visit here, a report that conveys something of the high expectations surrounding Pope Paul's visit. The address was originally delivered in French: text at the Vatican website here and audio on the United Nations site here.
Pope Paul's speech is memorable for its impassioned plea for peace:
Here our message reaches its culmination and we will speak first of all negatively. These are the words you are looking for us to say and the words we cannot utter without feeling aware of their seriousness and solemnity: never again one against the other, never, never again!
Was not this the very end for which the United Nations came into existence: to be against war and for peace? Listen to the clear words of a great man who is no longer with us, John Kennedy, who proclaimed four years ago: "Mankind must put an end to war, or war will put an end to mankind." There is no need for a long talk to proclaim the main purpose of your Institution. It is enough to recall that the blood of millions, countless unheard-of sufferings, useless massacres and frightening ruins have sanctioned the agreement that unites you with an oath that ought to change the future history of the world: never again war, never again war! It is peace, peace, that has to guide the destiny of the nations of all mankind!
But what I would like to explore is those sections of Pope Paul's address which indicate how he, and in his person the Holy See, understood the nature of the organisation that is the United Nations.
You offer the many States which can no longer ignore each other a form of coexistence that is extremely simple and fruitful. First of all, you recognize them and distinguish them from each other. Now you certainly do not confer existence on States, but you do qualify each nation as worthy of being seated in the orderly assembly of peoples. You confer recognition of lofty moral and juridical value upon each sovereign national community and you guarantee it an honorable international citizenship.
There are two components in this paragraph. The first is a recognition that each of the individual states is not able to ignore the others; the behaviours of any one state have an influence on the behaviours of other states. And then secondly, in this context, the UN is recognises for each national community a "moral and juridical value" in a relationship to the like value of every other state, what the speech terms "international citizenship". Each national community is recognised as being of account in the consideration of every other national community. "Your vocation is to bring not just some peoples but all peoples together as brothers", to use the words Pope Paul used later in his address. This same paragraph ends with the following sentence which, though it does not require further exposition, is nevertheless significant for its implications for what should govern the relations between states:
You [ie the UN] sanction the great principle that relationships between nations must be regulated by reason, justice, law and negotiation, and not by force, violence, war, nor indeed by fear and deceit.
Pope Paul identifies a mission of working for peace as being characteristic of the nature of the United Nations:
Gentlemen, you have accomplished and are now in the course of accomplishing a great work: you are teaching men peace. The United Nations is the great school where people get this education and we are here in the assembly hall of this school. Anyone who takes his place here becomes a pupil and a teacher in the art of building peace. And when you go outside of this room, the world looks to you as the architects and builders of peace.
As you know very well, peace is not built merely by means of politics and a balance of power and interests. It is built with the mind, with ideas, with the works of peace. You are working at this great endeavor, but you are only at the beginning of your labors.
We do now have many more years experience of the work of the United Nations than were available to Pope Paul in 1965, an experience during which the deliberations of the UN Security Council in particular have not infrequently been the scene of exactly the politics of power and individual interests (think, for example, of the lack of action with regard to Syria since the civil war broke out there) to which Pope Paul drew attention. Reading Pope Paul's words today makes us feel that those words need to be repeated again to recall the members of the United Nations to their essential vocation.
To speak of humaneness and generosity is to echo another constitutional principle of the United Nations, its positive summit: you are working here not just to eliminate conflicts between States, but to make it possible for States to work for each other. You are not content with facilitating coexistence between nations. You are taking a much bigger step forward, one worthy of our praise and our support: you are organizing fraternal collaboration between nations..... This is the finest aspect of the United Nations Organization, its very genuine human side....
What you are proclaiming here are the basic rights and duties of man, his dignity, his liberty and above all his religious liberty. We feel that you are spokesmen for what is loftiest in human wisdom - we might almost say its sacred character - for it is above all a question of human life, and human life is sacred; no one can dare attack it.
We do not need to say anything further on this dimension of the work of the United Nations as identified by Pope Paul, beyond perhaps suggesting that Pope Paul is identifying an idea of international fraternity in its work that would later become the subject of Pope Francis' encyclical Fratelli Tutti.
Whilst these passages indicate something of how Pope Paul understood the nature and mission of the United Nations, an earlier part of his address offers what might rather be seen as a prudential judgement of the UN as being "the obligatory path of modern civilization and world peace":
Permit us to say that we have a message, and a happy one, to hand over to each one of you Our message is meant to be first of all a solemn moral ratification of this lofty Institution, and it comes from our experience of history. It is as an "expert on humanity" that we bring this Organization the support and approval of our recent predecessors, that of the Catholic hierarchy, and our own, convinced as we are that this Organization represents the obligatory path of modern civilization and world peace.
Whilst it may not be perfect - and Pope Paul recognised that the United Nations was setting out on its path rather than having achieved its purpose - this is an organisation to which support should be given.
[Postscript: it is also worth noting that Pope Paul referred, in a very diplomatic way, to some specific issues in his address - disarmament, birth control, the economic and social progress of poorer nations, literacy and culture.]
