In chapter twelve of "To Kill A Mockingbird" what purpose does the scene bewtween Calpurnia and Lula at First Purchase church serve? List serveral...

This scene illustrates a couple of different things:

1. It shows that people of any color, class, or description can become uncomfortable with dramatic change or alteration of the usual. Lula serves as an example of this fear when she interrogates Calpurnia about her intent in bringing the Finch children to the service.

2. It also shows the value and merit of Calpurnia as a loyal ally of the Finches. She doesn't back down, she doesn't apologize, she just goes on about the business of church with the children in tow, illustrating her own dignity and quiet confidence. The kids learn that despite differences in methodology, the church service isn't that different from their average Sunday at their own church.
