“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.”

“If we do an eye for an eye and a tooth for a tooth, we will be a blind and toothless nation.”

“True peace is not merely the absence of tension: it is the presence of justice.”

“Not only will we have to repent for the sins of bad people; but we also will have to repent for the appalling silence of good people.”

“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.”

“A nation that continues year after year to spend more money on military defense than on programs of social uplift is approaching spiritual doom.”

“Timpul în sine este neutru. Şi va trebui să regretăm pe parcursul acestei generaţii nu doar cuvintele pline de ură şi acţiunile oamenilor răi, ci şi tăcerea înfricoşătoare a oamenilor buni.”

“Only when it is dark enough can we see the stars.”

“Science investigates, religion interprets. Science gives man knowledge which is power, religion gives man wisdom which is control. Science deals mainly with facts, religion deals with values. The two are not rivals. They are complementary. Science keeps religion from sinking into the valley of crippling irrationalism and paralysing obscurantism. Religion prevents science from falling into the marsh of obsolete materialism and moral nihilism.”

“I said to my children, 'I'm going to work and do everything that I can do to see that you get a good education. I don't ever want you to forget that there are millions of God's children who will not and cannot get a good education, and I don't want you feeling that you are better than they are. For you will never be what you ought to be until they are what they ought to be.”

“But I am also concerned about our moral uprightness and the health of our souls. Therefore I must oppose any attempt to gain our freedom by the methods of malice, hate, and violence that have characterized our oppressors. Hate is just as injurious to the hater as it is to the hated. Like an unchecked cancer, hate corrodes the personality and eats away its vital unity. Many of our inner conflicts are rooted in hate. This is why psychiatrists say, “Love or perish.” Hate is too great a burden to bear.”

“The potential beauty of human life is constantly made ugly by man's ever-recurring song of retaliation.”

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

“The limitation of riots, moral questions aside, is that they cannot win, and their participants know it.”

“Without love, there is no reason to know anyone, for love will in the end connect us to our neighbors, our children and our hearts.”
