identify and explain three things we learn about the african american community from jem and scout's visit to calpurnia's church

There are no hymnals in Calpurnia's church. Such books represent luxuries that the black church cannot afford. Calpurnia is insulted by church members who believe that she should not have brought white children to the black church; they find out what it is like not to be accepted. Calpurnia speaks very differently to the members of her "black community" in the church than she speaks when she is in the Finch household acting as their housekeeper.
