“We must reach out our hand in friendship and dignity both to those who would befriend us and those who would be our enemy.”

1950s, What Desires Are Politically Important? (1950)
Context: We love those who hate our enemies, and if we had no enemies there would be very few people whom we should love.
All this, however, is only true so long as we are concerned solely with attitudes towards other human beings. You might regard the soil as your enemy because it yields reluctantly a niggardly subsistence. You might regard Mother Nature in general as your enemy, and envisage human life as a struggle to get the better of Mother Nature. If men viewed life in this way, cooperation of the whole human race would become easy. And men could easily be brought to view life in this way if schools, newspapers, and politicians devoted themselves to this end. But schools are out to teach patriotism; newspapers are out to stir up excitement; and politicians are out to get re-elected. None of the three, therefore, can do anything towards saving the human race from reciprocal suicide.

Deeds Rather Than Words (1963)
Context: To me, today, at age sixty-one, all prayer, by the humble or highly placed, has one thing in common: supplication for strength and inspiration to carry on the best human impulses which should bind us together for a better world. Without such inspiration, we would rapidly deteriorate and finally perish. But in our troubled time, the right of men to think and worship as their conscience dictates is being sorely pressed. We can retain these privileges only by being constantly on guard and fighting off any encroachment on these precepts. To retreat from any of the principles handed down by our forefathers, who shed their blood for the ideals we still embrace, would be a complete victory for those who would destroy liberty and justice for the individual.

Day of Affirmation Address (1966)
Context: The help and the leadership of South Africa or of the United States cannot be accepted if we, within our own country or in our relationships with others, deny individual integrity, human dignity, and the common humanity of man. If we would lead outside our borders, if we would help those who need our assistance, if we would meet our responsibilities to mankind, we must first, all of us, demolish the borders which history has erected between men within our own nations — barriers of race and religion, social class and ignorance.
Our answer is the world's hope; it is to rely on youth. The cruelties and the obstacles of this swiftly changing planet will not yield to obsolete dogmas and outworn slogans. It cannot be moved by those who cling to a present which is already dying, who prefer the illusion of security to the excitement and danger which comes with even the most peaceful progress. This world demands the qualities of youth: not a time of life but a state of mind, a temper of the will, a quality of the imagination, a predominance of courage over timidity, of the appetite for adventure over the love of ease.

1950s, Loving Your Enemies (Christmas 1957)
Context: Jesus is eternally right. History is replete with the bleached bones of nations that refused to listen to him. May we in the twentieth century hear and follow his words-before it is too late. May we solemnly realize that we shall never be true sons of our heavenly Father until we love our enemies and pray for those who persecute us.
