“My friends, our challenge today is not to save Western civilization — or Eastern, for that matter. All civilization is at stake, and we can save it only if all peoples join together in the task.”

Maurice Strong, September 1, 1997 edition of National Review magazine

2000s, Interview with Peter Robinson (2009)

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.

The Saviors of God (1923)
Context: God is imperiled. He is not almighty, that we may cross our hands, waiting for certain victory. He is not all-holy, that we may wait trustingly for him to pity and to save us.
Within the province of our ephemeral flesh all of God is imperiled. He cannot be saved unless we save him with our own struggles; nor can we be saved unless he is saved.
We are one. From the blind worm in the depths of the ocean to the endless arena of the Galaxy, only one person struggles and is imperiled: You. And within your small and earthen breast only one thing struggles and is imperiled: the Universe.

1850s, Speech at Peoria, Illinois (1854)
Context: Our republican robe is soiled, and trailed in the dust. Let us repurify it. Let us turn and wash it white, in the spirit, if not the blood, of the Revolution. Let us turn slavery from its claims of “moral right,” back upon its existing legal rights, and its arguments of 'necessity'. Let us return it to the position our fathers gave it; and there let it rest in peace. Let us re-adopt the Declaration of Independence, and with it, the practices, and policy, which harmonize with it. Let north and south — let all Americans — let all lovers of liberty everywhere — join in the great and good work. If we do this, we shall not only have saved the Union; but we shall have so saved it, as to make, and to keep it, forever worthy of the saving. We shall have so saved it, that the succeeding millions of free happy people, the world over, shall rise up, and call us blessed, to the latest generations.

remarks (2 May 1956) at a Caltech YMCA lunch forum http://calteches.library.caltech.edu/49/2/Religion.htm
Context: Western civilization, it seems to me, stands by two great heritages. One is the scientific spirit of adventure — the adventure into the unknown, an unknown which must be recognized as being unknown in order to be explored; the demand that the unanswerable mysteries of the universe remain unanswered; the attitude that all is uncertain; to summarize it — the humility of the intellect. The other great heritage is Christian ethics — the basis of action on love, the brotherhood of all men, the value of the individual — the humility of the spirit.
These two heritages are logically, thoroughly consistent. But logic is not all; one needs one's heart to follow an idea. If people are going back to religion, what are they going back to? Is the modern church a place to give comfort to a man who doubts God — more, one who disbelieves in God? Is the modern church a place to give comfort and encouragement to the value of such doubts? So far, have we not drawn strength and comfort to maintain the one or the other of these consistent heritages in a way which attacks the values of the other? Is this unavoidable? How can we draw inspiration to support these two pillars of western civilization so that they may stand together in full vigor, mutually unafraid? Is this not the central problem of our time?
