To Our Venerable Brethren the Patriarchs, Primates, Archbishops, Bishops, and all other Local Ordinaries who are at Peace and in Communion with the Apostolic See, and to the Clergy and Faithful of the entire Catholic World, and to all Men of Good Will.

Venerable Brethren and Dearest Sons Health and Apostolic Benediction.

Peace on Earth-which man throughout the ages has so longed for and sought after-can never be established, never guaranteed, except by the diligent observance of the divinely established order.

Order in the Universe

2. That a marvelous order predominates in the world of living beings and in the forces of nature, is the plain lesson which the progress of modern research and the discoveries of technology teach us. And it is part of the greatness of man that he can appreciate that order, and devise the means for harnessing those forces for his own benefit.

3. But what emerges first and foremost from the progress of scientific knowledge and the inventions of technology is the infinite greatness of God Himself, who created both man and the universe. Yes; out of nothing He made all things, and filled them with the fullness of His own wisdom and goodness. Hence, these are the words the holy psalmist used in praise of God: "O Lord, our Lord: how admirable is thy name in the whole earth!"¹ And elsewhere he says: "How great are thy works, O Lord! Thou hast made all things in wisdom."²

Moreover,^2a God created man "in His own image and likeness,"³ endowed him with intelligence and freedom, and made him lord of creation. All this the psalmist proclaims when he says: "Thou hast made him a little less than the angels: thou hast crowned him with glory and honor, and hast set him over the works of thy hands. Thou hast subjected all things under his feet."⁴

Order in Human Beings

4. And yet there is a disunity among individuals and among nations which is in striking contrast to this perfect order in the universe. One would think that the relationships that bind men together could only be governed by force.

5. But the world's Creator has stamped man's inmost being with an order revealed to man by his conscience; and his conscience insists on his preserving it. Men "show the work of the law written in their hearts. Their conscience bears witness to them."⁵ And how could it be otherwise? All created being reflects the infinite wisdom of God. It reflects it all the more clearly, the higher it stands in the scale of perfection.⁶

6. But the mischief is often caused by erroneous opinions. Many people think that the laws which govern man's relations with the State are the same as those which regulate the blind, elemental forces of the universe. But it is not so; the laws which govern men are quite different. The Father of the universe has inscribed them in man's nature, and that is where we must look for them; there and nowhere else.

7. These laws clearly indicate how a man must behave toward his fellows in society, and how the mutual relationships between the members of a State and its officials are to be conducted. They show too what principles must govern the relations between States; and finally, what should be the relations between individuals or States on the one hand, and the world-wide community of nations on the other. Men's common interests make it imperative that at long last a world-wide community of nations be established.
