“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.”

“Hatred paralyzes life; love releases it. Hatred confuses life; love harmonizes it. Hatred darkens life; love illuminates it.”

“The belief that God will do everything for man is as untenable as the belief that man can do everything for himself. It, too, is based on a lack of faith. We must learn that to expect God to do everything while we do nothing is not faith but superstition.”

“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.”

“There comes a time when one must take a position that is neither safe, nor politic, nor popular, but he must take it because his conscience tells him it is right....” 

“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.”

“Any religion that professes to be concerned about the souls of men and is not concerned about the slums that damn them, the economic conditions that strangle them and the social conditions that cripple them is a spiritually moribund religion awaiting burial.”

“I am convinced that love is the most durable power in the world. It is not an expression of impractical idealism, but of practical realism. Far from being the pious injunction of a Utopian dreamer, love is an absolute necessity for the survival of our civilization. To return hate for hate does nothing but intensify the existence of evil in the universe. Someone must have sense enough and morality enough to cut off the chain of hate and evil, and this can only be done through love.” — Martin Luther King Jr.”

“Now is the time to make real the promises of democracy. Now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. Now is the time to open the doors of opportunity to all of God's children. Now is the time to lift our nation from the qu icksands of racial injustice to the solid rock of brotherhood.”

“One has not only a legal but a moral responsibility to obey just laws. Conversely, one has a moral responsibility to disobey unjust laws. I would agree with St. Augustine that ' an unjust law is no law at all.”

“Love is creative and redemptive. Love builds up and unites; hate tears down and destroys. The aftermath of the ‘fight with fire’ method which you suggest is bitterness and chaos, the aftermath of the love method is reconciliation and creation of the beloved community. Physical force can repress, restrain, coerce, destroy, but it cannot create and organize anything permanent; only love can do that. Yes, love—which means understanding, creative, redemptive goodwill, even for one’s enemies—is the solution to the race problem.”

“Through our scientific and technological genius we've made of this world a neighborhood. And now through our moral and ethical commitment we must make of it a brotherhood. We must all learn to live together as brothers—or we will all perish together as fools.”

“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. We must speak with all the humility that is appropriate to our limited vision, but we must speak.”

“People fail to get along because they fear each other; they fear each other because they don't know each other; they don't know each other because they have not communicated with each other.”

“The Christians who engaged in infamous persecutions and shameful inquisitions were not evil men but misguided men. The churchmen who felt they had an edict from God to withstand the progress of science, whether in the form of a Copernican revolution or a Darwinian theory of natural selection, were not mischievous men but misinformed men.”
