Fifty years ago today Martin Luther King, Jr. wrote and incredible open letter in response to eight white clergymen in Alabama who had written “A Call for Unity”. The letter still rings true even fifty years later when we read it. Here are two excerpts from the letter itself, you can read the letter in its entirety here.

…Rather, I have tried to say that this normal and healthy discontent can be channeled into the creative outlet of nonviolent direct action. And now this approach is being termed extremist. But though I was initially disappointed at being categorized as an extremist I gradually gained a measure of satisfaction from the label. Was not Jesus an extremist for love: “Love you enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you.” Was not Amos an extremist for justice:”Let justice roll down like waters and righteousness like an ever flowing stream.” Was not Paul an extremist for the Christian gospel: “I bear in my body the marks of the Lord Jesus.” Was not Martin Luther an extremist: “Here I stand; I cannot do otherwise, so help me God.” And John Bunyan: “I will stay in jail to the end of my days before I make a butchery of my conscience.” And Abraham Lincoln, “This nation cannot survive half slave and half free.” And Thomas Jefferson: “We hold these truths to be self evident, that all men are created equal…” So the question is not whether we will be extremists, but what kind of extremists we will be. Will we be extremists for hate or for love? Will be be extremists for the preservation of injustice or for the extension of justice? In that dramatic scene on Calvary’s hill three men were crucified. We must never forget that all three were crucified for the same crime—the crime of extremism. Two were extremists for immorality, and thus fell below their environment. The other, Jesus Christ, was an extremist for love, truth and goodness, and thereby rose above his environment. Perhaps the South, the nation and the world are in dire need of creative extremists.

Yes, these questions are still in my mind. In deep disappointment I have wept over the laxity of the the church. But be assured that my tears have been tears of love. There can be no deep disappointment where there is not deep love. Yes, I love the church. How could I do otherwise? I am in the rather unique position of being the son, the grandson and the great grandson of preachers. Yes, I see the church as the body of Christ. But oh! How we have blemished and scarred that body through social neglect and the fear of being nonconformist.

There was a time when the church was very powerful—in the time when the early Christians rejoiced at being deemed worthy to suffer for what they believed. In those days the church was not merely a thermometer that recorded the ideas and principles of popular opinion; it was a thermostat that transformed the mores of society. Whenever the early Christians entered a town, the people in power became disturbed and immediately sought to convict the Christians for being “disturbers of the peace” and “outside agitators.” But the Christians pressed on, in the conviction that they were “a colony of heaven,” called to obey God rather than man. Small in number, they were big in commitment. They were too God-intoxicated to be “astronomically intimidated.” By their effort and example they brought an end to such ancient evils as infanticide and gladiatorial contests. Things are different now. So often the contemporary church is a weak, ineffectual voice with an uncertain sound. So often it is an archdefender 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 even vocal—sanction of things as they are.

But the judgment of God is upon the church as never before. If today’s church does not recapture the sacrificial spirit of the early church, it will lose its authenticity, forfeit the loyalty of millions, and be dismissed as an irrelevant social club with no meaning for the twentieth century. Every day I meet young people whose disappointment with the church has turned into outright disgust.
