“Only a "dry as dust" religion prompts a minister to extol the glories of Heaven while ignoring the social conditions that cause men an Earthly hell.” 

“Lamentably, it is a historical fact that privileged groups seldom give up their privileges voluntarily. Individuals may see the moral light and voluntarily give up their unjust posture; but, as Reinhold Niebuhr has reminded us, groups tend to be more immoral than individuals.”

“We are going to win our freedom because both the sacred heritage of our nation and the eternal will of the Almighty God are embodied in our echoing demands. So however difficult it is during this period, however difficult it is to continue to live with the agony and the continued existence of racism, however difficult it is to live amidst the constant hurt, the constant insult and the constant disrespect, I can still sing we shall overcome. We shall overcome because the arc of the moral universe is long but it bends towards justice. We shall overcome because Carlisle is right. "No lie can live forever." We shall overcome because William Cullen Bryant is right. "Truth crushed to earth will rise again." We shall overcome because James Russell Lowell is right. "Truth forever on the scaffold, wrong forever on the throne."   Yet that scaffold sways the future. We shall overcome because the Bible is right.  "You shall reap what you sow." With this faith we will be able to hew out of the mountain of despair, a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to speed up the day when all of God's children all over this nation - black men and white men, Jews and Gentiles, Protestants and Catholics will be able to join hands and sing in the words of the old negro spiritual, "Free at Last, Free at Last, Thank God Almighty, We are Free At Last.”

“I became convinced that noncooperation with evil is as much a moral obligation as is cooperation with good.”

“And one day we must ask the question, "Why are there forty million poor people in America?" And when you begin to ask that question, you are raising questions about the economic system, about a broader distribution of wealth. When you ask that question, you begin to question the capitalistic economy.”

“Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.”

“It is cheerful to God when you rejoice or laugh from the bottom of your heart.”

“Take the first step in faith. You don't have to see the whole staircase, just take the first step.”

“Economic insecurity strangles the physical and cultural growth of its victims. Not only are millions deprived of formal education and proper health facilities but our most fundamental social unit—the family—is tortured, corrupted, and weakened by economic insufficiency. When a Negro man is inadequately paid, his wife must work to provide the simple necessities for the children. When a mother has to work she does violence to motherhood by depriving her children of her loving guidance and protection; often they are poorly cared for by others or by none—left to roam the streets unsupervised. It is not the Negro alone who is wronged by a disrupted society; many white families are in similar straits. The Negro mother leaves home to care for—and be a substitute mother for—white children, while the white mother works. In this strange irony lies the promise of future correction.”

“If a man hasn’t discovered something he will die for, he isn’t fit to live.”

“And somewhere along the way it is necessary to see that human progress never rolls in on the wheels of inevitability. It comes through the tireless efforts and the persistent work of dedicated individuals who are willing to be co-workers with God.”

“Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.”

“If a man is called to be a street sweeper. He should sweep streets even as a Michelangelo painted , or Beethoven composed music or Shakespeare wrote poetry. He should sweep streets so well that all hosts of heaven and earth pause to say; Here lives a great sweeper who did his job well "

“it is just as wrong, or even perhaps more so, to use moral means to preserve immoral ends.”

“La oscuridad no puede conducirte fuera de la oscuridad; sólo la luz puede hacer eso. El odio no puede conducirte fuera del odio; sólo el amor puede hacer eso.”
