describe jem's and scout's visit to first purchase church?

Calpurnia takes Scout and Jem to her own church. Re. Sykes and the congregation are all very hospitable to Scout and Jem. They know Atticus is sacrificing much defend Tom Robinson. Lula is one person who does not want Scout and Jem there, "Lula stopped, but she said, "You ain't got no business bringin' white chillun here – they got their church, we got our'n. It is our church, ain't it, Miss Cal?" Lula has a point. Hell would freeze over before a white church let a Black child in; Lula is just doing the same thing. Still, the difference is that they are the kids of Atticus and guests of Calpurnia. Zeebo the garbage collector apologizes to Jem, "Mister Jem," he said, "we're mighty glad to have you all here. Don't pay no 'tention to Lula, she's contentious because Reverend Sykes threatened to church her. She's a troublemaker from way back...." Scout and Jem see how poor the church is but they also see how rich in community and brotherhood it is as well.

scout and jem experience first-hand what it feels like to be the object of racial intolerance.

The experience of how they experience the way the black church has a poor community, but also a strong community as well.

They experience how poor the black church is.
