and still the dead have voices

I'm reading the speeches of MLK for a term paper, and in going through them, I think there's a lot we still haven't learned.

The following is an excerpt from "Paul's Letter to American Christians," which Dr. King gave as a sermon to Dexter Avenue Baptist Church in Montgomery, Alabama. He basically wrote a letter, from Paul (of the Bible) to Americans in then contemporary 1956 America. All emphasis is mine.

"Let me rush on to say something about the church. Americans, I must remind you, as I have said to so many others, that the church is the Body of Christ. So when the church is true to its nature it knows neither division nor disunity. But I am disturbed about what you are doing to the Body of Christ. They tell me that in America you have written within Protestantism more than two hundred and fifty six denominations. The tragedy is not so much that you have such a multiplicity of denominations, but that most of them are warring against each other with a claim to absolute truth. This narrow sectarianism is destroying the unity of the Body of Christ. You must come to see that God is neither a Baptist nor a Methodist; He is neither a Presbyterian nor an Episcopalian. God is bigger than all our denominations. If you are to be true witnesses for Christ, you must come to see that in America.

"But I must not stop with a criticism of Protestantism. I am disturbed about Roman Catholicism. This church stands before the world with its pomp and power, insisting that is possesses the only truth. It incorporates an arrogance that becomes a dangerous spiritual arrogance. It stands with its noble Pope who somehow rises to the miraculous heights of infallibility when he speaks "ex cathedra." But I am disturbed about a person or an institution that claims infallibility in this world. I am disturbed about any church that refuses to cooperate with other churches under the pretense that it is the only true church. I must emphasize the fact that God is not Roman Catholic, and that the boundless sweep of his revelation cannot be limited to the Vatican. Roman Catholicism must do a great deal to mend its ways.

"There is another thing that disturbs me to no end about the American church. You have a white church and you have a Negro church. You have allowed segregation to creep into the doors of the church. How can such a division exist in the true Body of Christ? You must face the tragic fact that when you stand at 11:00 on Sunday Morning to sing "All Hail the Power of Jesus Name" and "Dear Lord and Father of All Mankind," you stand in the most segregated hour of Christian America. They tell me that there is more integration in the entertaining world and other secular agencies than there is in the Christian church. How appalling that is."

This was November 4, 1956. How is it that almost exactly 50 years later we've still the same faults?
