“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?”

“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.” 

“It is simply my way of saying that I would rather be a man of conviction than a man of conformity. Occasionally in life one develops a conviction so precious and meaningful that he will stand on it till the end. That is what I have found in nonviolence.”

“Any religion that professes to be concerned with the souls of men and is not concerned with the slums that damn them, the economic conditions that strangle them and the social conditions that cripple them is a dry-as-dust religion.”

“Every man must decide whether he will walk in the light of creative altruism or in the darkness of destructive selfishness.”

“The hope of a secure and livable world lies with disciplined nonconformists who are dedicated to justice, peace and brotherhood.”

“I'm concerned about a better world. I'm concerned about justice; I'm concerned about brotherhood; I'm concerned about truth. And when one is concerned about that, he can never advocate violence. For through violence you may murder a murderer, but you can't murder murder. Through violence you may murder a liar, but you can't establish truth. Through violence you may murder a hater, but you can't murder hate through violence. Darkness cannot put out darkness; only light can do that.”

“If the inexpressible cruelties of slavery could not stop us, the opposition we now face will surely fail. We will win our freedom because the sacred heritage of our nation and the eternal will of God are embodied in our echoing demands.”

“Cowardice asks the question, 'Is it safe?' Expediency asks the question, 'Is it politic?' Vanity asks the question, 'Is it popular?' But, conscience asks the question, 'Is it right?' And there comes a time when one must take a position that is neither safe, nor politic, nor popular, but one must take it because one's conscience tells one that it is right”

“There comes a time when silence is betrayal.”

“noncooperation with evil is just as much a moral duty as is cooperation with good.”

“Love your enemies”

“We are not makers of history. We are made by history.”

“The church must be reminded that it is not the master or the servant of the state, but rather the conscience of the state. It must be the guide and the critic of the state, and never its tool. If the church does not recapture its prophetic zeal, it will become an irrelevant social club without moral or spiritual authority.”

“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.”
