“I believe in God who made of one blood all races that dwell on earth. I believe that all men, black and brown and white, are brothers, varying through Time and Opportunity, in form and gift and feature, but differing in no essential particular, and alike in soul and in the possibility of infinite development.”

"Social Justice and the Emerging New Age" address at the Herman W. Read Fieldhouse, Western Michigan University (18 December 1963)

1960s, Why I Am Opposed to the War in Vietnam (1967)
Context: We are presently moving down a dead-end road that can lead to national disaster. America has strayed to the far country of racism and militarism. The home that all too many Americans left was solidly structured idealistically; its pillars were solidly grounded in the insights of our Judeo-Christian heritage. All men are made in the image of God. All men are brothers. All men are created equal. Every man is an heir to a legacy of dignity and worth. Every man has rights that are neither conferred by, nor derived from the State — they are God-given. Out of one blood, God made all men to dwell upon the face of the earth. What a marvelous foundation for any home! What a glorious and healthy place to inhabit. But America's strayed away, and this unnatural excursion has brought only confusion and bewilderment. It has left hearts aching with guilt and minds distorted with irrationality.

This I Believe (1952)
Context: I believe in —  I am proud to belong to —  the United States. Despite shortcomings, from lynchings to bad faith in high places, our nation has had the most decent and kindly internal practices and foreign policies to be found anywhere in history.
And finally, I believe in my whole race. Yellow, white, black, red, brown — in the honesty, courage, intelligence, durability … and goodness …. of the overwhelming majority of my brothers and sisters everywhere on this planet. I am proud to be a human being. I believe that we have come this far by the skin of our teeth, that we always make it just by the skin of our teeth — but that we will always make it … survive … endure. I believe that this hairless embryo with the aching, oversize brain case and the opposable thumb, this animal barely up from the apes, will endure — will endure longer than his home planet, will spread out to the other planets, to the stars, and beyond, carrying with him his honesty, his insatiable curiosity, his unlimited courage — and his noble essential decency.
This I believe with all my heart.

Context: I believe in recognizing every human being as a human being, neither white, black, brown nor red. When you are dealing with humanity as one family, there's no question of integration or intermarriage. It's just one human being marrying another human being, or one human being living around and with another human being.

1950s, Give Us the Ballot (1957)
Context: We must not seek to use our emerging freedom and our growing power to do the same thing to the white minority that has been done to us for so many centuries. Our aim must never be to defeat or humiliate the white man. We must not become victimized with a philosophy of black supremacy. God is not interested merely in freeing black men and brown men and yellow men, but God is interested in freeing the whole human race. We must work with determination to create a society, not where black men are superior and other men are inferior and vice versa, but a society in which all men will live together as brothers and respect the dignity and worth of human personality.
