The problem with "black culture" is that it's what I call a "chit'lin' culture." I didn't understand what Malcolm X meant back when I was a kid in the 60s; I understand him better now.
What is a "chit'in' culture?" Chitterlings are the intestines of swine. They are nasty, filled with feces, generally considered garbage. During slavery, the masters got the choice portions of the hog, the slaves got maws, feet, tails, and entrails. The slaves learned to pick away the most noxious parts of the chit'lin's very, very carefully, boil them very hard, season them very heavily to make them palatable and not immediately deadly.
The same happened with culture. Slavers stripped the kidnapped Africans of their own cultures, but allowed them to have only the entrails of American culture. Slaves--and freedmen as well--were not allowed to participate in the "choice cuts" of American culture. For that portion of American culture they were allowed, they picked away the most noxious parts very carefully, boiled it very hard, and seasoned it very heavily to make it palatable and not immediately deadly.
But the basic truth about both chitterlings and American culture for black people: It's not nutritious and ultimately unhealthy. Malcolm X understood that and thus advocated that blacks cake a top-to-bottom critical examination of the culture that we had so long strive to emulate and join, in fact, to reject it and develop a "for us, by us" culture that was actually beneficial to our American situation.
He thought Islam presented such an alternative culture. I disagree because I know Jesus is real. But I agree that American black people need that top-to-bottom critical review of what we call "African-American culture" that would ultimately involve rejecting a great deal of it.
Even as Christians, I think American black people should do that top-to-bottom critical examination of the way white people have taught us to "do church." Not the basic doctrines, but how as Christians we relate to one another and to the society at large. What's good for the dominant ethnic group is not necessarily good for everyone in it. "African-American culture" is a broken culture, and it's always been broken.
For instance, American Christians tend to look at poverty as being the fault of the impoverished. From the early and general acceptance of the un-biblical "God helps those who help themselves" to the modern "if you're poor, it's because you don't have enough faith," the poor are most quickly presumed to be poor by their own fault.
These Christians will point to, generally, verses from Proverbs to prove their point. However...Proverbs was written during the Israel Monarchy. At that time, Israel was the Promised Land flowing with "milk and honey." The Mosaic Law had specific provisions to prevent the kinds of accumulated debt, permanent transfer and accumulation of wealth, and other things that would create a permanent poverty class. In Solomon's time, it was probably true that if an Israelite was poor for very long, it was probably his fault.
By the time of Jesus, that system was broken. Jesus was aware that the poor were poor because of systematic economic oppression...which continues to this day even more efficiently.
That's the kind of thing black people need to look at closely even in the way that we do church. The Western European form of Christianity is not the only form to consider.
