What does the visit to Calpurnia's church teach Jem and Scout? What was the purpose of the scene? How does the author create a meaningful scene?

In To Kill A Mockingbird, Calpurnia provides Jem and Scout with the rich experience of connecting the two worlds of blacks and whites

Explanation:

Calpurnia, the Finch's black housekeeper, provides a link between the black world and the white world in which the children move. She is a constant in their lives and fills a mothering role in the absence of their own mother. As a wise and loving black woman, Calpurnia provides the children with an experience which guards them against being drawn into the racist attitudes of the majority of their society.
