In November 2018 the Catholic bishops of the United States released a Pastoral Letter Against Racism called, Open Wide Our Hearts. The letter is a powerful invitation for all the people of God to “face courageously the vice of racism, . . . reach out generously to the victims of this evil, to assist the conversion needed in those who still harbor racism, and to begin to change policies and structures that allow racism to persist.”
At the below link you can read the entire letter, get new resources and find ideas for how we can respond.
"But racism still profoundly affects our culture, and it has no place in the Christian heart. This evil causes great harm to its victims, and it corrupts the souls of those who harbor racist or prejudicial thoughts. The persistence of the evil of racism is why we are writing this letter now."
