“The time comes when silence is betrayal. That time has come for us today...  ...some of us who have already begun to break the silence of the night have found that the calling to speak is often a vocation of agony, but we must speak.”

“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 "

“If it falls your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, sweep streets like Beethoven composed music, sweep streets like Leontyne Price sings before the Metropolitan Opera.

If you can't be a pine at the top of the hill, be a shrub in the valley. Be be the best little shrub on the side of the hill.”

“[If] a man doesn't have a job or an income, he has neither life nor liberty nor the possibility for the pursuit of happiness. He merely exists.”

“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.”

“History will have to record that the greatest tragedy of this period of social transition was not the strident clamor of the bad people, but the appalling silence of the good people.”

“I am tired of seeing people battered and bruised and bloody, injured and jumped on, along the Jericho Roads of life.”

“Wherever the early Christians entered a town the power structure got disturbed and immediately sought to convict them for being 'disturbers of the peace' and 'outside agitators.' But they went on with the conviction that they were a 'colony of heaven' and had to obey God rather than man. They were small in number but big in commitment. They were too God-intoxicated to be 'astronomically intimidated.' They brought an end to such ancient evils as infanticide and gladiatorial contest. Things are different now. The contemporary Church is so often a weak, ineffectual voice with an uncertain sound. It is so often the archsupporter of the status quo. Far from being disturbed by the presence of the Church, the power structure of the average community is consoled by the Church’s silent and often vocal sanction of things as they are.”
