Bishop Robert Barron has two excellent videos out on race prejudice and Catholic teaching/understanding.
One is on how Reverend Doctor Martin Luther King's "Letter From the Birmingham Jail" makes use of the reasoning of Saint Thomas Aquinas and why that is important for our nation. You can find that one HERE
The second is on the important relevance of Reverend King's enduring legacy for us as Christians. You find that one HERE
