I'm not American, or Black, but there have been many good African Bishops, Church Fathers, who have blessed the Universal Church. https://en.wikipedia.org/wiki/Church_Fathers
That glorious list includes St. Augustine of Hippo and St. Athanasius of Alexandria. The Church is not just America, where Christianity arrived much later, or any other individual nation alone. She is Universal and has a 2000 year History. Yes, yes, there are racial differences between different people groups, that's true, and of course it has to do with both Nature and Nurture, but it's also true that (1) God made Adam in His Own Image, and we are all descended from Adam. (2) God freely adopts as His Children in Baptism people from every race. (3) Our Lord Jesus Christ shed every drop of His Precious Blood for every single person. (4) As St. Paul says (Acts 17:26), He has made all mankind from one first father, and so we are all related. (5) Those of the same race as you are more closely related to you than others. We should love people of our own race, of course. I do. But we should not condemn or despise or look down on people of a different race and imagine, especially when they are Christians, and Grace has begun to aid Nature, that they can never rise, either materially or spiritually, to great heights. All the races and every person has their own role to play in God's Plan of Salvation. Once upon a happy time, Catholic Europe sent Christian Missionaries to the farthest ends of the world. The time may one day come when Christian missionaries from other parts of the world re-evangelize Europe/America.
Pope Ven. Pius XII famously said, after warning of the Crisis in the Church, and the ѕυιcιdє of altering the Faith in the Liturgy etc, as warned by Our Lady of Fatima, that missionaries would one day rise up from Africa, from Asia and from America: "These underdeveloped peoples will save the Church, Eminence. A day will come when the civilized world will deny its God, when the Church will doubt as Peter doubted. She will be tempted to believe that man has become God, that His Son is only a symbol, a philosophy like so many others. And in churches, Christians will search for the red lamp where Jesus awaits them, like the sinful woman crying out before the empty tomb: ‘Where have they taken Him?’
Then, priests will rise up from Africa, from Asia, from America, formed here in this seminary of the Missions, who will say and who will proclaim that the ‘bread of life’ is not ordinary bread, that the mother of the God-man is not a mother like others. And they will be cut to pieces to testify that Christianity is not a religion like others, since her head is the Son of God, and the Church is His Church."
