Final answer:
The church service at First Purchase and the Finch children's normal church differ in their treatment of women and leadership roles.
Step-by-step explanation:
The differences between the church service at First Purchase and the service at the church the Finch children normally attended can be seen in the treatment of women and leadership roles within the church.
At First Purchase, the church service reflects a more inclusive approach towards women. While women had greater freedom of expression, they were still granted fewer leadership roles and authority compared to men.
On the other hand, the church the Finch children normally attended, which aligns more with the attitudes in the South, reasserts the dominance of men and largely limits the roles and authority of women within the church.
