“And I must say tonight that a riot is the language of the unheard. And what is it America has failed to hear? ... It has failed to hear that the promises of freedom and justice have not been met. And it has failed to hear that large segments of white society are more concerned about tranquility and the status quo than about justice and humanity.”

“When I took up the cross I recognized it's meaning. The cross is something that you bear, and ultimately, that you die on.”

“The richer we have become materially, the poorer we become morally and spiritually. We have learned to fly in the air like birds and swim in the sea like fish, but we have not learned the simple art of living together as brothers.”

“One has a moral responsibility to disobey unjust laws.”

“„Понякога в живота има моменти на неизразимо удоволствие, което не може напълно  да бъде обяснено със тези символи, наречени думи. Тяхното значение може  да бъде изразено само от недоловимият език на сърцето.”

“On some positions, cowardice asks the question, is it expedient? And then expedience comes along and asks the question, is it politic? Vanity asks the question, is it popular? Conscience asks the question, is it right?

“Whatever affects one directly, affects all indirectly. I can never be what I ought to be until you are what you ought to be. This is the interrelated structure of reality.”

“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.”

“Let no man pull you low enough to hate him.” 

“There are two types of laws, those that are just and those that are unjust. A just law is a man-made code that squares with the moral law. An unjust law is a code that is out of harmony with the moral law...Any law that uplifts the human personality is just. Any law that degrades human personality is unjust. All segregation statutes are unjust because segregation distorts the soul and damages the personality.”

“The greatness of our God lies in the fact that [He] is both tough minded and tender hearted. ... [God] expresses [His] tough mindedness in [His] justice and wrath and [His] tenderheartedness in [His] love and grace. ... On the one hand, God is a God of justice who punished Israel for her wayward deeds, and on the other hand, [He] is a forgiving father whose heart was filled with unutterable joy when the prodigal son returned home.”

“Let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred.”

“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.”

“My call to the ministry was not a miraculous or supernatural something. On the contrary it was an inner urge calling me to serve humanity.”

“Whatever I was, I owed to my family and to all those who struggled with me. But my biggest debt I owed to my wife. She was the one who gave my life meaning. All I could pledge to her, and to all those millions, was that I would do all I could to justify the faith that she, and they, had in me. I would try more than ever to make my life one of which she, and they, could be proud. I would do in private that which I knew my public responsibility demanded.”
