How does Scarlet Sister Mary develop the theme of Race and Class?

Scarlet Sister Mary by Julia Peterkin develops Race and Class across the chapters the companion marks for this theme.

The narrative opens with a hierarchical view of Gullah people as superior to other Black groups, and the plantation's legacy of slavery shapes the characters' lives, revealing how race and class intersect in post-Civil War rural South.

The description of the Gullahs as 'far the best black people' and the contrast with 'common white trash' highlights internalized racial hierarchies and class distinctions within the post-slavery South.
