“Worship at its best is a social experience with people of all levels of life coming together to realize their oneness and unity under God. Whenever the church, consciously or unconsciously caters to one class it loses the spiritual force of the "whosoever will, let him come, doctrine and is in danger of becoming a little more than a social club with a thin veneer of religiosity.”

“All this is simply to say that all life is interrelated. We are caught in an inescapable network of mutuality; tied in a single garment of destiny. Whatever affects one directly, affects all indirectly. As long as there is poverty in this world, no man can be totally rich even if he has a billion dollars. As long as diseases are rampant and millions of people cannot expect to live more than twenty or thirty years, no man can be totally healthy, even if he just got a clean bill of health from the finest clinic in America. Strangely enough, I can never be what I ought to be until you are what you ought to be. You can never be what you ought to be until I am what I ought to be.”

“...law and order exist for the purpose of establishing justice and that when they fail in this purpose they become the dangerously structured dams that block the flow of social progress.”

“Love is the only force capable of transforming an enemy into a friend.”

“There can be no deep disappointment where there is not deep love.”

“I've looked over, and I've seen the promised land. I may not get there with you, but I want you to know tonight that we as a people will get to the promised land. So I'm happy tonight. I'm not worried about anything. I'm not fearing any man. ”

“Whatever measure of influence I had as a result of the importance which the world attaches to the Nobel Peace Prize would have to be used to bring the philosophy of nonviolence to all the world’s people who grapple with the age-old problem of racial injustice.”

“Time itself is neutral; it can be used either destructively or constructively”

“[Nonviolence] is directed against forces of evil rather than against persons who happen to be doing the evil. It is evil that the nonviolent resister seeks to defeat, not the persons victimized by evil.”

“During a crisis period, a desperate attempt is made by the extremists to influence the minds of the liberal forces in the ruling majority. So, for example, in the present transition white Southerners attempt to convince Northern whites that the Negroes are inherently criminal.”

“The mere fact that we live in the United States means that we are caught in a network of inescapable mutuality. Therefore, no American can afford to be apathetic about the problem of racial justice. It is a problem that meets every man at his front door. The racial problem will be solved in America to the degree that every American considers himself personally confronted with it. Whether one lives in the heart of the Deep South or on the periphery of the North, the problem of injustice is his problem; it is his problem because it is America’s problem.”

“Todo hombre debe decidir si caminará a la luz del altruismo creativo o en la oscuridad del egoísmo destructivo. Éste es el juicio. La pregunta más urgente, e ineludible, de la vida es: ¿Qué estás haciendo por los demás?”

“Something is happening in Memphis; something is happening in our world. And you know, if I were standing at the beginning of time, with the possibility of taking a kind of general and panoramic view of the whole of human history up to now, and the Almighty said to me, "Martin Luther King, which age would you like to live in?" I would take my mental flight by Egypt and I would watch God's children in their magnificent trek from the dark dungeons of Egypt through, or rather across the Red Sea, through the wilderness on toward the promised land. And in spite of its magnificence, I wouldn't stop there. I would move on by Greece and take my mind to Mount Olympus. And I would see Plato, Aristotle, Socrates, Euripides and Aristophanes assembled around the Parthenon. And I would watch them around the Parthenon as they discussed the great and eternal issues of reality. But I wouldn't stop there. I would go on, even to the great heyday of the Roman Empire. And I would see developments around there, through various emperors and leaders. But I wouldn't stop there. I would even come up to the day of the Renaissance, and get a quick picture of all that the Renaissance did for the cultural and aesthetic life of man. But I wouldn't stop there. I would even go by the way that the man for whom I am named had his habitat. And I would watch Martin Luther as he tacked his ninety-five theses on the door at the church of Wittenberg. But I wouldn't stop there. I would come on up even to 1863, and watch a vacillating President by the name of Abraham Lincoln finally come to the conclusion that he had to sign the Emancipation Proclamation. But I wouldn't stop there. I would even come up to the early thirties, and see a man grappling with the problems of the bankruptcy of his nation. And come with an eloquent cry that we have nothing to fear but "fear itself." But I wouldn't stop there.”

“The first principle of value that we need to rediscover is this: that all reality hinges on moral foundations. In other words, that this is a moral universe, and that there are moral laws of the universe just as abiding as the physical laws. (from "Rediscovering Lost Values")”

“One day the absurdity of the almost universal human belief in the slavery of other animals will be palpable. We shall then have discovered our souls and become worthier of sharing this planet with them.”
