Agreed with Madison here--you've framed this really well, and it's one of the reasons why I think Heng's work is so important. Because it gives a long genealogy of race and racism, we can see how DEEPLY embedded ideologies around race into primary cultural touchstones like in this case Christian theology. Thinking ahead to the final project (which I'll send around a message about in the next day), this might be an interesting topic for you to develop further.
