Describe the significance of Scout's experience at Calpurnia's church in To Kill a Mockingbird.

I'm not sure that Scout values the First Purchase African
Methodist Episcopal Church all that much, but it is important to her for two reasons:
First, it is Calpurnia's church (and probably the only African-American church in
Maycomb). Secondly, she enjoyed the visit that she made with Jem and Cal, getting a
first-hand experience of a Sunday in a black church. Having met Reverend Sykes there,
the children are later invited to sit with him in the balcony during the Tom Robinson
trial. It is important to the novel for this very reason. It is probably the center of
social life for Maycomb's black citizens, and Tom and his family also are members of
First Purchase.
