What Did Christianity Look Like Prior to Modern Raceism?

The division is not based on skin color, it's based on whether you're christian or moslem. Why in this period are there four people who are dark skinned african sen who are consecrated as bishops in the roman catholic church? You won't see that again, for the most part, until you get to he twentieth century, i say, the rise of modern racism. The challenge for me is, what did christianity look like prior to modern raceism,. So that we can better understand how we are so shaped by race to day that we can't see race even when it's not there.
