“We must move into the universe. Mankind must save itself. We must escape the danger of war and politics. We must become astronauts and go out into the universe and discover the God in ourselves.”

Source: The Life of St. Teresa of Jesus (c.1565), Ch. XXV. "Divine Locutions. Discussions on That Subject" ¶ 1 & 2
Context: It will be as well, I think, to explain these locutions of God, and to describe what the soul feels when it receives them, in order that you, my father, may understand the matter; for ever since that time of which I am speaking, when our Lord granted me that grace, it has been an ordinary occurrence until now, as will appear by what I have yet to say.
The words are very distinctly formed; but by the bodily ear they are not heard. They are, however, much more clearly understood than they would be if they were heard by the ear. It is impossible not to understand them, whatever resistance we may offer. When we wish not to hear anything in this world, we can stop our ears, or give attention to something else: so that, even if we do hear, at least we can refuse to understand. In this locution of God addressed to the soul there is no escape, for in spite of ourselves we must listen; and the understanding must apply itself so thoroughly to the comprehension of that which God wills we should hear, that it is nothing to the purpose whether we will it or not; for it is His will, Who can do all things.

1960s, Keep Moving From This Mountain (1965)

Australians in a Nuclear War (1983)
Context: I have derived immense comfort, hope, faith, inspiration from a great American, the Cistercian monk-teacher-activist Thomas Merton. Initially a contemplative religious, Merton's spiritual drive was aimed at halting the dehumanization of man in contemporary society, a sickness he saw as leading to mass violence and ultimately nuclear war. War of any kind is abhorrent. Remember that since the end of World War II, over 40 million people have been killed by conventional weapons. So, if we should succeed in averting nuclear war, we must not let ourselves be sold the alternative of conventional weapons for killing our fellow men. We must cure ourselves of the habit of war.

1790s, Discourse to the Theophilanthropists (1798)
Context: The universe is the bible of a true Theophilanthropist. It is there that he reads of God. It is there that the proofs of his existence are to be sought and to be found. As to written or printed books, by whatever name they are called, they are the works of man's hands, and carry no evidence in themselves that God is the author of any of them. It must be in something that man could not make, that we must seek evidence for our belief, and that something is the universe; the true bible; the inimitable word, of God.

1961, UN speech
Context: Ladies and gentlemen of this Assembly, the decision is ours. Never have the nations of the world had so much to lose, or so much to gain. Together we shall save our planet, or together we shall perish in its flames. Save it we can — and save it we must — and then shall we earn the eternal thanks of mankind and, as peacemakers, the eternal blessing of God.
