“I have generally made it a rule to parry the inquiries and comparisons which the Americans are so apt to thrust at an Englishman. On one or two occasions, when the party has been numerous and worth powder and shot, I have, however, on being hard pressed, and finding my British blood up, found the only mode of allaying their inordinate vanity to be by resorting to this mode of argument:—"I admit all that you or any other person can, could, may, or might advance in praise of the past career of the people of America. Nay, more, I will myself assert that no nation ever did, and in my opinion none ever will, achieve such a title to respect, wonder, and gratitude in so short a period; and further still, I venture to allege that the imagination of statesmen never dreamed of a country that should in half a century make such prodigious advances in civilization and real greatness as yours has done. And now I must add, and I am sure you, as intelligent, reasonable men, will go with me, that fifty years are too short a period in the existence of nations to entitle them to the palm of history. No, wait the ordeal of wars, distresses, and prosperity (the most dangerous of all), which centuries of duration are sure to bring to your country. These are the test, and if, many ages hence, your descendants shall be able only to say of their country as much as I am entitled to say of mine now, that for seven hundred years we have existed as a nation constantly advancing in liberty, wealth, and refinement; holding out the lights of philosophy and true religion to all the world; presenting mankind with the greatest of human institutions in the trial by jury; and that we are the only modern people that for so long a time withstood the attacks of enemies so heroically that a foreign foe never put foot in our capital except as a prisoner (this last is a poser);—if many centuries hence your descendants will be entitled to say something equivalent to this, then, and not till then, will you be entitled to that crown of fame which the historian of centuries is entitled to award."”

Preface to The Autumn in the Spring (May 1932) http://www.learn-chinese.org/modernprose1/bachun/chunt01.htm
Context: In the past several years, my hard work, my books which I wrote through blood and tears, and the purpose of my life all has been focused on: helping everyone to have a spring, so that everyone's heart will be bright, everyone will have a happy life, and everyone will have the freedom to develop in any way they want. I aroused people to have thirst for, thirst for brightness; I put a cause in front of people, a cause which is worthy of people's devotion. But all of my hard work was destroyed by another power. After arousing a young soul, it only made him or her suffer more unbearable trampling torment.

An allusion to the Abraham Lincoln's House Divided Speech and a reference to the Gospel of Matthew, 12:25: "[Every] city or house divided against itself shall not stand."
1960s, October surprise speech (1968)
Context: Throughout my entire public career I have followed the personal philosophy that I am a free man, an American, a public servant, and a member of my party, in that order always and only. For 37 years in the service of our Nation, first as a Congressman, as a Senator, and as Vice President, and now as your President, I have put the unity of the people first. I have put it ahead of any divisive partisanship. And in these times as in times before, it is true that a house divided against itself by the spirit of faction, of party, of region, of religion, of race, is a house that cannot stand.

Context: I am not very impressed with theological arguments whatever they may be used to support. Such arguments have often been found unsatisfactory in the past. In the time of Galileo it was argued that the texts, "And the sun stood still... and hasted not to go down about a whole day" (Joshua x. 13) and "He laid the foundations of the earth, that it should not move at any time" (Psalm cv. 5) were an adequate refutation of the Copernican theory.
